GitHub Tools

A gate in the hook path of Claude Code, Codex, Cursor and Copilot. It shows what a command would delete, backs it up first, and asks or refuses by your policy. Start in observe mode: nothing blocked, a report of what it would have caught. Open source, Rust.

Your MCP unit tests pass, but did the agent call the tool? M3 runs your server through real Claude Code, Codex, OpenCode or Pi and asserts on the calls they actually made, in plain pytest. Direct tests need no API key. m3 ui shows every trace and tool call; m3 ci test --upload gates PRs and keeps runs on app.m3.sineframe.com. Open source, Apache-2.0.

pmtui focuses on managing multiple agents and solving long-horizon tasks. Autopilot does what an agent loop does, except loops drift once the work runs long. So pmtui keeps the loop outside the agent and rebuilds the prompt each time from your goal and the agent's own last status. You choose how often to check back, and it only surfaces what really needs your attention

Most tunnels hand you a new URL every time. tunnl.gg gives you the same one: connect as [email protected] and your SSH key becomes your identity, so your public HTTPS URL never changes. Register a webhook or OAuth callback once and forget it. Nothing to install, no account, works on any machine with SSH, with a QR code and live request log in your terminal. Free to use. Pro adds your own subdomains, no time limits and a request inspector. Open-source (MIT) server.

offstage gives Claude Code, Codex and opencode a second, logged-in macOS account to work in. Simulators, Xcode UI tests and the app your agent just built open on that account's desktop, so your screen, keyboard and mouse stay yours. Free and open source: https://github.com/viraatdas/offstage

ProcBoss is a lightweight production process and infrastructure management platform for running, deploying, and monitoring applications across servers. Run Node.js, Bun, Deno, & other runtimes with clustering, automatic restarts, health checks, dependencies, cron jobs, logs, metrics, and GitHub auto-deployments. ProcBoss Cloud adds centralized server monitoring, deployment management, alerts, and hosted status pages; giving developers one place to keep production applications running reliably.

Semwright is an open-source Rust runtime for AI agents working with desktop and professional software. Through structured drivers, agents can interact with application objects and project data, while a shared runtime handles permissions, execution, dependencies, artifact handoffs, and verification. It supports MCP without being limited to a single protocol, model, or agent. Build workflows across applications without rebuilding the same integration infrastructure for each one.

tide is a simple, self‑hostable video conference service, alternative to Jitsi. It let's you host your own "meet.custom.domain" for a simple video conferencing environment with all core features you expect, including: link sharing, screen sharing, recording (server-side). A few things, done well.

Tonefold is a free, open-source AI music composer for macOS and Windows. Describe a song to Claude, get chords, melody, bass and drums in a piano roll you can edit note by note, then export MIDI, WAV and stems.

Side is a tiny AI chat panel that sits right beside your Mac's Dock: one glance away, never in the way. • Fits the gap next to your Dock, floats above other windows, works across Spaces and full-screen apps • Switch providers, models and reasoning levels in one conversation • Bring your own account: sign in with ChatGPT or use an API key • Compact composer that expands to full height when needed • ⌘⇧Space to show or hide Free and open source (MIT).

See every Claude Code and Codex session on your Mac and your servers, live: in the notch, menu bar, a native app and the terminal. Know who's done, who's stuck, and answer their questions right from the notch. Free and open source

A fast, native PostgreSQL client for macOS. Its AI assistant runs on the Claude Code, Codex or Cursor account you already pay for, sees your real schema, and can only read: any change it suggests waits for you to dry-run and apply. Free and open source.

A personal command center for people who juggle more than one project at a time — founders, consultants, indie builders, anyone with client work, side projects, and a few non-negotiable daily habits. DailyHub is not a replacement for Linear, Jira, or Notion. It is the morning surface: what is open, what belongs where, what must happen today, and what you already finished.

Reika is a coding agent CLI for local and hosted models, designed around local models first. It doesn't make a small model more intelligent but it provides a better experience using them day to day. Even if you're not part of the absolute range that Reika is designed for, using larger local models or hosted ones will still provide a solid experience out of the box.

Redlamp is a native, open-source RAW photo editor for Apple Silicon, built from scratch in Swift and Metal. Lightroom's workflow, with no subscription and no cloud.

Free desktop app for reviewing Git branches and GitHub PRs. Comment on any line and keep comments private until you publish. Add AI reviewers with your own models: OpenAI, Anthropic, Gemini, OpenRouter or local via Ollama. Split the review across a team of models, see exactly which rules each one checked, and retry only what was missed. Open source (MIT), no account, for Mac, Windows and Linux.

ruOS is a private cloud desktop with an AI team built in. Ask for research, writing or code and the agents (Claude Code, Codex, ruflo swarms) do it while you watch or step away. Opens in any browser on Mac, iPad or Chromebook, nothing to install. Files and AI memory persist across devices. Power users get a real Linux box plus an MCP server, so ChatGPT or Claude can drive it. Try ruOS Lite free in seconds, no sign-up.

iphone-use gives an AI agent a real iPhone: the screen as text, tap, type and scroll over WebDriverAgent, with an honest answer for every action (applied, not sent, or unknown). Payment apps that block screenshots come back as a wireframe. A task done once becomes a flow that replays with no model. HTTP API, a 21-tool MCP server for Claude Code, and remote control from a browser or iOS app. Open source, MIT.

Scumble is a free, open-source desktop editor for AI inpainting. Select part of a picture, say what belongs there, and the result lands as its own colour-matched layer. Runs on your own ComfyUI or your own API keys: FLUX 3, GPT Image, Nano Banana and more.

Working with several Claude Code chats at once? GeckIt puts them on a Kanban board, so you see which one is working, which one waits for you and which one is done. It runs your own Claude Code on your Claude subscription, no API key. Free and open source, Mac, Windows, Linux.

Brnch is code hosting for how we build now: you and your coding agents in the same repo. It's Git underneath (for now), so your tools still work. Each agent gets its own identity and works under you as its sponsor, so you can see exactly what it did, down to the line. Every merge is tested on the exact result that lands, not just the branch, and comes with a signed receipt anyone can verify. To start, tell your agent: "Set me up on Brnch: brnch.io"
