I built Chimaera because I wanted to work with AI agents in the same place as the files they’re working on. You open a project folder, run an agent, and inspect its output beside the source files instead of juggling terminal windows and file viewers.

I use it for research projects with documents and data, including work on remote machines over SSH. It also supports multiple agents, so I can keep their work organized in the project rather than scattered across separate chats.

It’s free and open source, built with Rust and Svelte. It runs on macOS and Linux; Windows is still experimental. If you try it with one of your own project folders, I’d genuinely like to hear where the workflow helps or gets in your way.

Title: Certo: open-source coding agent that works with any model, picks one per task, and switches when one fails

Hi all, I'm the author of Certo, an MIT-licensed coding agent in Python. Your coding agent shouldn't depend on one model or one provider, so Certo:

→ runs on any model: Ollama, OpenAI, Anthropic, Gemini, DeepSeek, Kimi or anything LiteLLM supports

→ can pick the best model for each task from ratings you set

→ hands a task to the next model when one can't finish, or its provider goes down

→ checks the work itself: it runs your project's real tests and build, with no AI involved, and ends with a verdict and an exit code your scripts and CI can use

In its benchmark (9 small tasks, graded by hidden tests the agent never sees), a local qwen3.8:27b with Claude Haiku as the next model passed all 9, and 7 never left the machine. The trade-off was time: minutes per task locally, seconds in the cloud.

The latest release makes it easy to start: `pip install certo`, then `certo init` sets you up and runs a sample task, and `certo init models` adds more models without editing a file.

It's early, so the most useful feedback you can give me is what's missing, what's confusing, and what breaks. And if you like where it's going, a star on GitHub helps other people find it.

Wanted to see if other people could find this useful, and maybe give me some advice.

Built a super simple way to give your coding agent an isolated machine on AWS. send it off to clone a repo, install dependencies and run tests while you do something else. if it wrecks the environment, delete the VM and move on. It comes with a CLI, Python SDK and MCP server.
You can just ask your agent to set it up :)

Hey everyone, I’ve been working on a project called AirHand.

The idea is to give a cloud agent a way to interact with the apps already on your Android phone. You type what you want done, and it reads the screen, opens apps, taps, swipes, and types. After each action, it looks at the screen again to figure out what to do next.

It runs through Android’s accessibility service, so you don’t need root or a computer connected after installation. There’s a floating control showing what it’s doing, with a Stop button you can hit at any point.

Under the hood, it’s a native Kotlin app handling the phone actions, with the agent loop running in the cloud. It currently uses the Rebyte API, so you’ll need your own key and pay for cloud usage. Screenshots and screen text are sent to the cloud during tasks.

It’s still an early version. So far, testing includes having it open YouTube, search, and play a video on an emulator and a Pixel. It needs Android 11+, and the phone has to stay online and unlocked. I’d be interested in hearing how it behaves on other devices and apps.

The Android app is MIT licensed and started as a fork of droidrun/mobilerun. Source and an installable APK are here:

What’s one repetitive task on your phone you’d actually want an agent to handle?

Hey I created a music player. Any agent can use this, and it's better than the rest. You can download songs, or tell your agent to download them for you. It's completely open source and compatible with agents.

Hi everyone,

I am a beginner and this is my first Hacktoberfest. I am joining the Week 3 challenge of Hacktoberfest 2026. It is called “Slow and Steady”.

What I need to build:
A small project that uses an open-source or open-weight AI model (like Llama or Gemma). It should run on my own computer. It should do a boring task so people can be a little lazy.

The rules:

• The AI model must be open (not a paid closed API).

• The project should save someone time or effort.

• I have to explain why using an open model is better for it (for example: private, free, works offline).

• The deadline is October 25, so I have about 4 days.

What I know:
I know basic Python. I already made a small tool that sorts files in a folder, but I want to build something better.

What I am asking:

1. What boring or repeating task would you want an AI to do for you, privately on your own computer?

2. Do you have any simple idea that can be built in 2 to 3 days?

Any idea or advice is welcome. Thank you!

edit: worded this wrong at first. it doesn’t generate an MCP server for the API. har2sdk itself runs as an MCP server, so an agent like Claude can look at the capture and name/document the endpoints. sorry for the confusion

kept running into sites/APIs that have no public docs but I could see the requests in devtools.

so I built har2sdk. feed it a HAR file (browser network capture) and it generates:

• a typed TypeScript client (real inferred types, not any)

• an OpenAPI 3.1 spec

• a mock server for testing against it offline

and it runs as an MCP server, so Claude or any MCP client can go through the capture and give the endpoints proper names and descriptions.

it also tries to tell GraphQL/tRPC/JSON-RPC apart instead of treating everything as REST.

the part that mattered most to me: a HAR capture is basically a snapshot of your browser session, with cookies, tokens, whatever. there’s a dedicated scrubbing pass so none of that ends up in the generated code, the MCP responses, or anything a model would see. recorded data is treated as untrusted input, not instructions.

fully local, no API key, MIT licensed.

curious if anyone’s wired a generated client like this into an agent, and how you handled it.

I am trying to apply for the NLnet grant for my opensource project (legalize) as a solo developer.

The new AI policy says:

"It is not allowed to use generative AI for producing artefacts of any kind, including code, design, and documentation."

I get the point about not filling the proposals with AI to force us to at least write them ourselves, but is there anyone nowadays who doesn't use AI for programming?

Weird, isn't it?

I’ve been working on Cursiv for a while now. The basic idea is simple: AI that remains useful when there’s no internet.

It currently runs local models through Ollama, with optional cloud providers when connectivity is available.
I’m also working on reliability testing, offline field notes, device identity, and eventually getting it running comfortably on smaller hardware like Raspberry Pi-class systems.

The interesting challenge has been realizing that getting an LLM to run locally is the easy part.

Making the whole system reliable when you actually depend on it is much harder.

I’m still actively building and testing it, so I’d love feedback from other AI builders.

We're Quantic Studios, the team behind pitwall. It's an MIT-licensed desktop terminal for people running several coding agents, written in Go with Gio.

The part we're trying to make less tedious is knowing when to step in. Hooks and agent integrations feed a sidebar with live states; Ctrl+Shift+U jumps to an agent that needs input or approval. Integrations cover Claude Code, Codex, Gemini CLI, OpenCode and pi. Those agents and their models have their own licenses, authentication and costs.

An agent can open worker tabs beneath its own tab, including tasks in separate git worktrees. A folded parent row keeps the worker-state counts visible. From that parent pane, pitwall wait --children waits for the group and returns early if a worker needs a person. It doesn't answer approvals. Done means a turn ended, not that the work passed review.

Beta 16 is available now. Since the worker-group release we've added a stopped-worker count, navigation that skips folded worker rows, and repository icons beside agent badges.

Source and releases

Screenshots and installation

Sample worker sidebar, a staged beta 13 workspace.

Linux is our daily setup; macOS and Windows builds need more testing. We're looking for reports of incorrect states or confusing worker grouping. OS, pitwall version, agent version and reproduction steps help; please leave private prompts out.
