Agentic Coding GitHub Repositories (2026) · Open Source Tools

Let Claude Code and other coding agents drive and debug Chrome from the shell. DOM, network, console and raw CDP as short commands, no screenshots and no MCP needed.

Start, stop, and duplicate dev projects with one click. The best workspace for running Claude Code, Codex, and other AI agents alongside your services.

A CLI that turns a goal into a pull request - and a sandbox for testing concurrent AI coding agents on the Mozaik runtime.

MCP server for AI-assisted development of CAP applications

Engineering discipline for AI coding agents: question the request, verify against current docs, plan, build test-first on the cheapest capable model, review with a second model family, prove it before saying done. One repo for Claude Code, Codex, Antigravity, Cursor, Gemini CLI and OpenCode.

Open-source, agent-first GitHub and GitHub Actions alternative that runs on your own Cloudflare account: git hosting, pull requests, code review and drop-in GitHub Actions YAML on Workers, Durable Objects, R2 and Containers.

Agentic coding, in your control

Open source autonomous engineering harness in your cloud. One sandbox per task, no real secrets inside.

One IDE for you and your AI team. A VS Code fork where Claude Code, Codex, Antigravity, and Muse Code work in parallel across multiple projects and features.

Your coding agents, working together as one team. Claude Code, Codex, Cursor and 13 more talk to each other, split the work on a shared board and check each other's work, each in its own git worktree. Free, open source, on your own plans and your own computer. macOS, Windows, Linux.

Mission control for long Claude Code runs: context and run progress at a glance, Autopilot handoffs, guardrails and a calm activity view, in the terminal and Claude Desktop.

Your team votes on how its AI coding agents behave. Correct Claude Code once, and PeerHarness turns it into a one-sentence rule (an Agent Skill) that a majority of your team votes in for every member's agent. Peer-to-peer, no server.

Fast, tiny AI coding agent for the terminal, written in Rust. One small native binary for Apple Silicon Macs. Works with OpenAI, Anthropic and compatible LLMs; MCP, subagents, plan mode, prompt-cache-friendly.

Open-source desktop app and VS Code extension for Meta's Muse Code CLI, with threads, inline diffs and approvals on Windows, macOS and Linux. Unofficial, not affiliated with Meta.
