Coding Agents GitHub Repositories (2026) · Open Source Tools

Local-first agent platform: board + role agents + agent CLI runs (Claude Code, Cursor, Antigravity, OpenCode) or local and API models (Ollama, LM Studio), all on your own Mac

Understand what your codebase builds, why it is structured that way, and what a change could affect. One shared Markdown ontology for humans and coding agents—visualized for people, accessible to agents through MCP, and reviewed with Git. Local-first. Open source.

Multi-agent task orchestration for coding agents. Turn one goal into an ordered plan of tasks (each with its own runner, model and mode), then execute and verify the results.

Reusable project context and specialist workflows for the AI tools you already use. Agents, skills, rules and MCP tools for Claude Code, Codex, Copilot, Cursor and more, plus SDLC workflows, session memory, and Jev decision support that offloads bounded LLM decisions to save tokens.

Open-source workspace manager for AI coding CLIs: Claude Code and ChatGPT Codex in one browser app. Discovers every session on disk, embedded terminals, phone-ready, cost tracking, kanban, docs. Windows, macOS, Linux.

Unofficial native macOS app for Herdr: read, follow and reply to your coding agents (Claude Code, Codex, Cursor, pi) in one place.

Open-source plugin for designing and reviewing software with agents

Open cross-harness protocol with terminal and local web interfaces

Rebuild any UI from a reference and prove it with a score. An Agent Skill for Claude Code and other coding agents: captures a site, screenshot or screen recording, then scores the clone on layout, style, pixels and motion until it passes.

A Git extension for tracking the AI-generated code in your repos

System of record for how agents build software: Built-in rust harness & 20+ CLIs.

Entity-level git merge driver. Resolves false conflicts git invents when independent agents edit the same file. ~95% reduction vs. line-based merge.

Local first, desktop companion platform with animated pets, plugin SDK and coding-agent integrations.

Open source AI code review for coding agents. A separate reviewer checks every change your agent writes before you push, in Claude Code, Codex, Cursor and Cline. No account or key of its own.

Open-source cross-agent memory layer for coding agents via MCP. Compatible with Claude Code, Codex, Cursor, Windsurf, Gemini CLI, Antigravity, OpenClaw, Hermes Agent, Oh-my-Pi, Pi, Copilot, Kiro, OpenCode, and Trae.

GPU-accelerated terminal board that puts all your sessions on an infinite canvas

TUI and CLI for browsing models.dev, benchmarks, coding agents, and statuses for AI providers.

Agentic SDLC infrastructure. Define guardrails. Collect signals. Enforce continuously. Signed records of what your AI coding agents and CI/CD pipelines did, checked against policies as code, with the loop closed in CI/CD. AI sessions, SBOMs, VEX, SARIF and SLSA provenance, built on Sigstore and in-toto. Apache 2.0.

The agent harness for .NET: embeddable, extensible, remotely controllable and ready to use.

Run coding agents without babysitting them. Keep jobs focused, bounded, checked and accountable from start to finish. Finally run your agents swarms overnight and get your time back.
