Open Minis
An on-device AI Agent that runs on your phone, open & secure
ProductivityGitHub

Open Minis is a free, open-source AI agent for iOS and Android that does more than chat — it gives the model a real computer to work with. A sandboxed Alpine Linux shell runs on your device: it installs packages, runs Python, edits real files and drives a browser. Around it, 30+ native bridges reach HealthKit, HomeKit, Calendar, Photos. etc. Bring your own model — Claude, GPT, Gemini, Kimi, Grok, or any OpenAI-compatible endpoint. Keys and data never leave your phone. Free and Open Source.

Break down large changes into a manageable chain of dependent pull requests.
cligh-extensiongithubstacked-prs

Stacked pull requests are a development workflow that allows you to decompose a large feature or bug fix into a series of smaller, linked pull requests. This solves the problem of unwieldy, hard-to-review mega-PRs by enabling incremental, independent review and merging of dependent changes. It's designed for developers and teams working on complex features who want to maintain code quality and streamline the review process.

Yamanote 3D is a free browser experience inspired by Tokyo’s Yamanote Line. Walk through an E235 carriage, sit down, watch the city, listen to announcements, and get off at stations. I built it to have realistic train sounds and city ambience in the background while studying or working. Feedback is very welcome.

Why is this running? Trace process, port, container or file
LinuxOpen SourceDeveloper ToolsGitHub

ps, top and lsof tell you what is running. witr tells you why. Point it at a process, PID, port, container or file and it traces the chain that explains it - systemd, supervisor, shell or cron - plus who started it, when, from where, and the warnings worth knowing. Run it bare for an interactive TUI with Processes, Ports, Containers and Locks tabs. Or script it: --short for a one-line chain, --json with real exit codes. One static Go binary for Linux, macOS, Windows and BSD.

Push-to-talk dictation that inserts in place: hold fn, speak, release, and the text appears in the app your cursor is already in. Transcription runs locally with whisper.cpp + Metal, so your audio never leaves the Mac. An optional on-device cleanup pass strips filler words and fixes punctuation. Most dictation apps show you a recording dot or a generic soundwave. This one has hand-animated indicators. $10 once, no subscription. MIT source. macOS 14+, Apple silicon.

You kick off an AI agent, switch tabs, and forget it's stuck or 90% through its context window. tablo fixes that, a tiny cat in your screen corner watching every Claude Code & Codex session: live context meters, tool approvals, and a nudge the second one needs you. Unlike usage dashboards, tablo tracks the conversation context filling up in real time, per session, across both tools — in a widget that stays out of your way. cozy by default. 🐱

Self updating wiki for coding agents
Open SourceDeveloper ToolsArtificial IntelligenceGitHub

Greplica gives your engineering team and every coding agent a shared memory of the codebase. It continuously extracts decisions, constraints, gotchas, failed approaches, and file-level context from coding sessions, then retrieves only what matters for the task at hand. Unlike static docs or siloed agent memory, Greplica stays grounded in the repo, keeps knowledge fresh, and works across developers, agents, clones, and forks. It is open source, runs locally, and offers a managed shared mode.

Open-source voice dictation for Mac, fully on-device

See what your Claude Code sessions actually cost
Open SourceDeveloper ToolsArtificial IntelligenceGitHub

Track Claude Code usage: cost, cache, session replay. Run `npx langwatch claude` once. Every session gets cost with cache reads/writes as separate token classes, every bash and MCP call as a span, theoretical vs billed for your Max plan, and a full terminal replay in the UI. Works for Codex too.
