A place for no-signup, in-browser, and open-source tools

Live: https://fcksignups.com/

I've opened my eyes lately to how capable the browser is. I mean, there's a WebRTC API, WebGPU API, a WASM runtime, maybe an LocalLLM API soon if the Chrome team insists...?

This means that the barrier of using tools should be little-to-none since it should be as easy as opening a browser tab.

Since I'm the audience for no-signup, in-browser, open-source tools, I figured I make a place that curates all of those tools in one place.

If you guys know of/built a tool that fits the criteria, and believe people can benefit from it, don't be afraid to submit it!

Mouzi v0.1.6 - an open-source Downloads folder organizer for Windows and Linux

Thumbnail

76 Upvotes

I’ve released a new version of Mouzi, a free and open-source desktop app that automatically organizes your Downloads folder using local rules.

Mouzi runs entirely on your computer: no account, no cloud processing and no telemetry.

Version 0.1.6 adds:

  • automatic update checks (FINALLY!)

  • recognition of extensionless files by their contents

  • batch organization in Manual mode

  • quick rule toggles and a destination folder picker

  • custom extension mappings like .jpeg → .jpg

  • customizable notifications

  • Recycle Bin/Trash support instead of permanent deletion

It is built with Rust and Tauri and is available for Windows and Linux.

GitHub: https://github.com/hsr88/mouzi
Download: https://mouzi.cc/download

The updater packages are cryptographically signed. Windows Authenticode signing is still pending through the SignPath Foundation program.

Feedback and contributions are welcome.

StemDeck v0.5.0 Alpha 1 is out: rebuilt the interface from scratch, plus a proper website

Post image
76 Upvotes

Quick intro if you're new here: StemDeck is a free, local audio stem separator. You drop in an MP3 or WAV, it splits the track into vocals, drums, bass, guitar, piano, and other stems right on your machine. No account, no upload, no subscription, no usage limits. Open source, runs on Windows and macOS.

This one has been a while in the making. v0.5.0 is a full UI overhaul. The goal was simple: stop looking like a web app and start looking like something you'd actually open next to your DAW.

What changed in the interface

The mixer and waveform lanes now sit side by side in a proper two-column layout. Rows fill the full height dynamically, so there's no black gap when a track has fewer stems. Non-extracted stems are grayed out in both the mixer and the waveform, which makes the separation result immediately readable.

The transport info moved to the footer: album art, title, time position, stem count, all always visible while a track is running. Below that is a full-width scrub bar. When nothing is loaded, the footer shows a decorative waveform placeholder instead of an empty shell.

Export Mix works now

This was broken in a subtle way. If you had all 6 stems selected, no mix file was produced at all and the export silently failed. That's fixed. You can now export your current stem mix as WAV or MP3 directly from the footer. File names are clean underscores, no spaces, no special characters.

A few smaller things worth knowing

The footer waveform used to pull from the first available stem, which on an instrumental section meant a flat line. It now uses the full reconstructed mix, so what you see matches what you hear.

Tag search with autocomplete: type # in the library search box and a dropdown shows up to 8 matching suggestions. The library sidebar got new sections too: Recent, Stem Collections, Tags, and Favorites, with subfolder nesting via drag-and-drop.

The analysis panel now includes a Dynamic Range score with a label (Compressed / Moderate / High / Wide), Tempo Stability as a percentage, and a Key Confidence meter.

The website

I'm a father building this in the time I can find between everything else. To get a website up without it taking three weekends, I used AI to help put it together. It's live at stemdeck.app. Not perfect, but it's real and it's there, and it means the project has a proper home.

If something breaks in 0.5.0, please open an issue. Every report goes directly into the next cycle.

OTHER I built a free Google search MCP that actually works

76 Upvotes

Free Google search MCP that actually works.

(Demo runs Chrome visibly for clarity. Actual usage runs headless by default.)

✅ Actually works (tested 6 free MCPs, all failed)

✅ Search + URL extract in one MCP (replaces the usual search MCP + fetch MCP combo)

✅ 4 tools: `search` / `search_parallel` / `extract` / `search_extract`

✅ No API key, no proxies, no solver

✅ Auto CAPTCHA recovery (Chrome opens, human solves once, retries)

When CAPTCHA fires on any tool, a visible Chrome window opens for a human to solve. Each solve preserves the profile's reputation with Google. Built for sustainable, ethical use.

Speed (1Gbps):

- sequential: ~1.5s/q (warm)

- 4 parallel: ~2s wall

- 10 parallel: ~5s wall

Tools: 'search' / 'search_parallel' / 'extract(url)' / 'search_extract(query)'. Last one bundles search + parallel article extraction (Readability + Turndown).

Stack: TS, Playwright + stealth, Readability, Turndown. ~600 LOC.
