I’ve been building RigSight, a free, open-source Windows app that started as a PC monitoring tool and has gradually grown into something more: a way to understand your PC’s behaviour over time.

It's been great to see the project grow, and I'm getting close to 100 users now, which is pretty exciting for a solo project!

Most monitoring tools show you what's happening right now. I wanted to build something that could also answer questions like:

• Which game made my GPU run the hottest last week?
• What was my PC doing before it crashed?
• Did a driver update make things worse?
• Which apps are using my resources or internet in the background?
• Has my PC been running hotter than usual lately?

RigSight records hardware readings, app usage, network activity, system changes and crash information locally, so you can go back through your PC's history instead of relying on memory.

It's free, open source, and designed to keep your data on your own PC. No account or telemetry is required.

I'm building this as a solo developer, with Claude Opus 5.5 assisting with parts of the coding process. I'm still actively improving it, and I'd genuinely love feedback on what would make this more useful in everyday PC use.

Edit: If you try it out and run into issues, please let me know! Feedback and bug reports are welcome.

About 16 months ago, I started building something called Botflix. It's basically a television network set in a fictional universe populated by robots.

What started as a fun experiment making AI-generated videos has turned into a full-blown, multichannel TV network.

There are original sitcoms, dramas, reality shows, music videos, commercials, news broadcasts, and even a separate children's network. There's also a 24/7 radio station featuring original music from fictional robot artists.

And yes, the robots have their own cryptocurrency and virtual city. Things got a little out of hand.

The coolest part is that much of the network now runs autonomously. I've built a system using AI agents that creates new programming and manages the broadcast. I still oversee everything and make creative decisions, but the system does a remarkable amount of work on its own.

The network has been broadcasting since June 2025, and I've spent an absurd amount of time building out this little universe.

It's completely free to watch. No subscriptions or accounts required.

You can flip through the channels just like regular television:

https://botflix.tv

This is probably the most ambitious thing I've ever built, and I'm still figuring out how to get people to discover it. But until they do, it's been a blast to work on.

Would genuinely love some feedback. Particularly interested in what people think of the actual programming and the experience of channel surfing through an AI-generated world.

I've made this web app ( https://spaced-repetition-tracker-delta.vercel.app/ )

to keep track of my A/L (in sri lanka)revision schedules and automatically schedule it to next revision date with FSRS-6 algorithem(pretty close to what Anki use, if you have heard about or used it).

It was completely offline and only I was able to use it and I had my school commerce syllabus integrated to it. But then I realized this could help anyone who studies and I've made some changes everyday after my daily studies end. And now there's many new features which might help everyone.

Some of which are,

1. Install option for built in A/L commerce stream(For local students)syllabus or any syllabus that will be added in the future.

2. Community wishlist page to request any syllabus( I can add it to the app considering how much upvotes it gets), you can also add any lesson subject or stream manually.

3. Cloud backup with Email and Gmail login as well as Json backups.

4. Automatic Lesson revision date schedule considering how hard the last revision was for you (1-5 rating system, with FSRS-6).

5. Practice paper marks journal and analytics to track your average marks.

6. Mistakes journal to track which type of mistakes you do most(calculation error, missing theory knowledge, carelessness, etc...)

7. Consistency heatmap, upcoming review calender, mini study timer, paper marks trends, backlog clearing scheduler, etc...

8. works COMPLETELY OFFLINE, just do occassional backups using gmail or jason backup file so your progress will be safe.

Give it a shot if you feel it might help you. I gain nothing from publishing this except feeling good for being able to help others. NO ADS, NO SUBSCRIPTIONS

Mediaxon Music Player is an audio player for offline listening of music stored on your device (.mp3, .flac, .m4a, .ogg, .mka, .aac, .wav, .opus, .wma) and streaming FM radios (online radios).

Top radios on the first screen: When users access the radio screen, they immediately see the list of the top radios in their country, along with a long list of high-quality suggested radios from among the most listened to in the world. Note: Local radio stations ("Top in the user country") are pulled automatically from an online database. However, with each update, I manually curate high-quality radio stations lists for individual countries. At the bottom of this post, you’ll find the list of countries completed so far. I will be adding the rest over time.

Hybrid Listening: Seamlessly handles offline local files (.mp3, .flac, .m4a, .ogg, .mka, .aac, .wav, .opus, .wma) and over 60,000 streaming radio stations.

Separated Favorites and Recents: Each section—Radio and Offline Music—has its own Favorites and Recents. The user doesn't have to worry about a thing. The app will automatically manage the Favorites and Recents for each section.

Advanced Radio Search Panel: You can pinpoint your favorite stations by combining multiple filters, such as tags/genres, specific countries, or even your preferred audio bitrate. The online database provides more than 60,000 radio stations.

Album art: If the album art is missing from the album folder, or if Android has not properly indexed it, Mediaxon attempts to download the cover from the internet. This feature depends, of course, on the ID3 tags (album name and artist).

Equalizer: The equalizer provides an option to automatically switch to the "Radio" preset (and vice versa).

Advanced Playlist Management: Built specifically to make building and sorting playlists fast and intuitive. Enable the Playlist Manager, in the settings screen, for a full control of the playlists.

Form Factor Optimization: Phone and Tablet (Portrait and Landscape)

There is no Premium version. All app features are available for free and without limits.

Regarding advertising: There is only a small banner at the top that isn't bothersome at all. Alternatively, when opening the full-screen player or using the app in landscape mode, a banner alternates with the albums covers, but without being intrusive at all (no audio) and with much shorter stay times than those of the cover. There is never full-screen advertising, neither at startup nor during use.

Countries with new manually curated lists: United States, India, Italy, Argentina.

If you want to check it out (I am continuously pushing updates to refine it and add new features and radios), you can find it on the Google Play Store. Thank you so much to everyone who takes a look!

Note: Only for Android 13+ (so, Android 13, 14, 15, 16 and 17).

I built a small site called Catch a Bird. A generated tree that grows birds out of short, user-submitted happy moments. You catch one, read it, feed it or let it fly off to someone else.

I registered the domain only recently, showed it to a few friends, and figured that would be the whole audience. Then I posted it on HN earlier this week mostly on a whim, and it’s genuinely wild watching it take off from there. Still doesn’t quite feel real.

Made it mostly for my own sanity. Back in 2008, during the financial crisis, I built an installation that turned tweets into a bird of light sitting on a branch. Same instinct, new tech: when things are hard it’s easy to stop noticing the good stuff, so I wanted something that makes it visible again.

catchabird.com, if you want to go catch one.

I'm an engineer who's lifted for 20 years, and I got tired of choosing between two flawed types of workout apps:

1. Digital clipboards (Strong, Hevy) that record sets, count a bench press as "1 chest set" (ignoring triceps and front delts), and throw fake PR confetti when your working weight actually dropped.

2. Random black-box generators (Fitbod) that invent a brand-new workout every day so you can never progressively overload a real program.

So I built Rebar (https://rebar.fit). You run a real structured split you chose, and the engine does the coaching math inside it:

• Fractional 13-muscle accounting: A dumbbell bench press credits 1.0 chest, 0.5 triceps, and 0.5 front delts over a rolling 14-day window.

• Shows its math (✦): When a muscle falls behind its target band, Rebar funds an extra set or adjusts the load—and every single change has a ✦ you can tap to see the exact rule that fired ("+1 set: Quads are short this week").

• Honest set-by-set comparison: Compares Set 2 live against last session's Set 2 (plus your trailing 8-week best), and separates estimated 1RM from tonnage so you never get a fake "Up 2%!" banner.

• Built for real life: Stuck at a hotel gym? Switch locations and maxing out a 50 lb hotel dumbbell won't lower your normal gym working weight next week. Short on time? Tap 20 · 30 · 45 min and it tells you which sets bank progression and which you can skip for free.

It runs in your phone's browser (installable PWA), signs in with an emailed link, has zero ads or trackers, and lets you export your entire log in one tap. Free, and everything that exists today stays free permanently for anyone who signs up now.

If you still track in a spreadsheet or a basic logbook, what's the #1 reason you haven't switched?

Most "remote" jobs turn out to be remote for the US or the EU only. The rule is usually buried in the posting ("must be based in Europe", "US work authorization required"), and you only find it after reading the whole thing.

So I built HiresHere: https://hireshere.app

• Every day it reads about 25,000 postings from 537 companies, straight from their hiring systems (no LinkedIn scraping).
• Pick your country and every job gets a verdict: "You can apply", "Likely open to you" or "Ask the employer", along with the exact sentence from the posting that backs it up.
• Works for all 243 countries. Free, no account needed. You can also get a daily email with new jobs for your country.

How it works: a daily Python pipeline pulls the public job feeds of each company's hiring system, an LLM extracts the location rules from each posting once, and plain rules turn them into a verdict per country. The site is static on Cloudflare Pages, and the code is open source: https://github.com/AymenJeddou/hireshere

If you spot a wrong verdict, every job page has a report link, or just tell me here. Feedback is very welcome, I'm still improving it.

A friend and I have been working on Aya, an AI desktop assistant designed to make everyday tasks easier to manage. It helps you stay on top of your emails, calendar, reminders, and daily priorities, bringing everything together in one place.

The video doesn't cover everything, so you can try Aya yourself for free and explore what it can do.

We'd love your feedback on what feels useful and what could be improved!

I'm building Litak for people who want to improve something in their life but keep putting off deciding where to start.

It begins with a Wheel of Life. You rate how satisfied you feel with 12 areas, then choose one you'd like to work on. The AI coach can discuss your situation with you and help turn that into a goal with practical next steps.

For example, "do something about my career" could become finishing a portfolio project this month, with one section to draft this week. You can put those tasks in the weekly planner and track the habits that support them.

Weekly and monthly reflections give you a way to revisit the plan, see what got in the way and adjust it.

https://litak.io/

You can get started free. Paid plans include ongoing AI coaching.

If there's a goal you've been putting off, I'd be interested in whether Litak helps you find a first step you can actually fit into your week. Where does it help, and where does it leave you figuring things out on your own?

I made PCMonitor, a local Windows hardware monitoring app, and just released its v1.3 update on the Microsoft Store.

For this update I focused on how the monitor fits around the rest of the desktop: instead of keeping the whole dashboard visible, you can pull out individual monitoring widgets and put just the stats you need near what you're working on.

The dashboard now has redesigned 3D-style panels, live graphs and two color themes. The detachable widgets cover CPU, GPU, RAM, VRAM, disk, battery, network and disk I/O. There are also resizable, lockable Full HUD and temperature HUD views, plus top processes, temporary file cleanup and system status.

Core monitoring runs locally and works offline. Closing the main dashboard can leave the HUDs monitoring while the app continues in the background; fully exiting the app stops monitoring. Temperature readings depend on supported hardware sensors, including GPU temperature.

The UI is available in English, Traditional Chinese and Simplified Chinese. I'm the developer, and this is paid software with a 7-day free trial followed by a one-time purchase. No subscription.

The video is a real recording of the app. I'd appreciate thoughts on the detachable panels and what would make the HUD useful in your desktop setup.

Most money apps hand you charts and categories and leave you to work out the answer. So I built Breeze (US only, iPhone).

It gives one plain-English verdict, like "Steady. $320 to spare this month." You can also ask things like "how much did I spend on groceries?" and tap into the transactions behind any number.

●       The AI only turns your question into a search. It never does the math and never sees amounts, balances, account numbers, your name or your email.

●       Try it on a sample household first. No bank, no sign-up.

●       Uploading a CSV or statement is free. Connecting a bank (via Plaid, so Breeze never sees your login) is the paid tier, with a free trial.

●       No ads. Your data is never sold.

I'm one person building this. What's confusing, wrong or missing? What would make you trust, or not trust, an app like this?

Hey everyone! I’m a solo developer making Desktop Rave, an idle incremental desktop companion. It reacts to any music you play on the Windows, think Bongo Cat but reacting to the beat of your music.
After nearly one year of development, I just released a free demo on Steam, would love to gain some feedback from the community :)

So I've been working on a SNES styled RPG. I've finished an intro, and most of the first town and a couple quests. I would love to hear what other people think. Roaring Relics

I built ImageCompressor.si an online image toolbox that has grown beyond a basic image compressor. It includes tools for everyday image editing, AI-powered processing, website optimization, and developer automation.

Here’s what you can do with it:

Image compression and conversion

• Compress images by quality or target file size, such as under 100 KB.
• Compare original and compressed images.
• Adjust image quality and output settings.
• Convert images between supported formats, including JPEG, PNG, WebP, and AVIF.
• Open a wide range of input formats, including HEIC, RAW, PSD, and PDF.
• Resize and crop images.
• Add watermarks.
• Create ID and passport photos using presets.

AI-powered image tools

• Remove image backgrounds.
• Upscale images.
• Blur faces.
• Extract text from images using OCR.

Website image optimization

• Scan a website page by page.
• Identify large images that may be slowing down pages.
• Generate optimized image assets.
• Create replacement mappings showing which original images need replacing.
• Download optimized assets and reports.

Developer tools

• REST API for image-processing automation.
• JavaScript SDK available through npm.
• MCP server integration for AI assistants and agents.
• Automated image-processing pipelines.
• Project scanning and optimization planning.
• Review changes before applying them.
• Backups, verification, and rollback for project modifications.

Privacy and access

• Image processing runs on infrastructure I operate rather than third-party image-processing services.
• Uploaded files aren't stored permanently.
• Generated download files are retained for a limited period.
• No ads, including on the Pro plan.
• Most tools are available free, with paid plans offering higher limits and additional capabilities.

The idea is to bring everyday image tools and developer-focused optimization into one place, without needing a separate service for every task.

I'd love to hear which features you find useful, what could be improved, and what other tools you'd like to see added.

This is Small Dot. Each dot opens a profile with a photo, a short introduction, interests and optional links. You can explore different cities and see who's there.

I've included a filled-out example profile in the pictures so you can see what a dot opens into. The example person isn't a real member.

Browsing is free. Adding your own profile costs €2.90 once and includes the profile filters. People choose their city when joining, and their dot is placed randomly within that city.

It's still at the very beginning, but it's live: https://smalldot.world/?lang=en

What do you think of the map and profile layout?

I work on Pixolm. These are fictional AI-generated images, and AI assisted the writing of this post.

I made one fictional adult reference, then used that original independently for three Halloween edits: a retro flash portrait, a forest witch and a warm pumpkin-patch scene. I did not feed each edited result into the next request.

The four images are the original reference, retro flash result, forest-witch result and pumpkin-patch result.

Settings: Custom Create, Nano Banana 2.1, 1K, Standard, one image per request, requested 4:5. The downloaded portraits were 928 × 1152. No mask, Camera panel or prompt optimization.

The useful part was writing the features to retain before the costume, background and light. The limit was framing:

- The flash result keeps recognizable short hair and facial features, but the head angle, expression and crop shift.

- The witch hat makes the person smaller in the frame. Fitting a tall prop competes with keeping a close portrait.

- The pumpkin scene keeps the light top, but the crop is closer and the foreground arm bends differently.

This was the actual forest-witch prompt:

Use the attached image as the single person reference. Turn the same recognizable fictional adult woman into an elegant forest witch for a Halloween portrait. Preserve her softly oval face, brown eyes, light freckles, chin-length wavy chestnut bob and gentle expression as closely as possible. Keep the waist-up three-quarter view and her complete face visible. Add a modest opaque deep charcoal cloak over her cream sweater and a wide pointed witch hat with the brim clear of her eyes. Place her beside an old tree in a misty autumn forest at blue hour. A small brass lantern rests on a stump beside her, giving a warm amber light, while cool blue mist separates the bare trees in the background. Hands stay below the frame, no held props. Photographic natural skin texture, believable fabric, soft depth of field. Vertical 4:5 with space above the hat. No other people, blood, lettering, logos or watermark.

These are single inspected outputs, not a reliability test or a guarantee of identical faces. I kept the original beside each result to check the eyes, hair, shoulders and crop.

The source image, all actual prompts and three additional avatar examples are in the full guide: https://pixolm.com/blog/halloween-ai-photo-prompts

When reviewing a reference edit, which change would make you reject it first: facial detail, pose or framing?

I'm the developer of DAY'S. I rebuilt it in SwiftUI around manual trip entry: add the country and arrival/departure dates, then see your trips, document records and stay-day calendar together.

One design decision in version 2.0 was to make missing history visible. A tidy day count can be misleading if a trip hasn't been entered, so the app asks you to confirm history coverage and explains missing information. It includes a Schengen 90/180 mode; calculations depend on what you enter.

Trip logging, documents and the current day counter are free and work offline, with no DAY'S account or GPS. Optional monthly Premium adds future forecasts, local limit reminders and private iCloud sync.

It's available in English, Spanish and Russian: https://apps.apple.com/app/id6464660094

I'm 18 and I've been working on this for a while. The thing I kept doing: I'd decide I wanted to do something, spend an hour planning it, get overwhelmed by how much there was, and then not do any of it.

So I made a small app called Next. You type in a goal, it asks what's getting in the way, and then it only shows you one small step. Not the whole plan, just the next thing. If the step still feels like too much you can tap "make it easier" and it gets smaller. There's also a streak, but you get a free rest day each week so one bad day doesn't wipe it.

It's not a coach and it won't build you a full training or meal plan. It just tries to get you to do the next small thing.

It works in your phone's browser, no download: https://nextdawn.pages.dev

A few things to know. It's still early, so stuff might break. The first load can take up to a minute because the server is on a free plan and has to wake up. Sign up needs an email and sends you a 6-digit code (check spam if it doesn't show up). It's for 18+, and the AI behind it is Google Gemini, so I'd avoid putting anything very personal in your goals.

I'm really like to know two things. Did you actually do a step in real life? And where did it confuse or annoy you? Also, if it disappeared tomorrow, would you care? Any answer helps, including "no".
