Open Source AI Code Assistants Apps

The self-hosted developer control center for running AI coding agents — locally, in Docker, on VMs, or across cloud backends — with automation workflows for GitHub, Slack, and more.

An open-source AI coding agent that lives in your editor and terminal — reads and edits your codebase, runs commands, browses the web, and requires human approval for every action by default.

A fully open-source AI coding agent built for the terminal, with a TUI, desktop app, web client, plugin system, and SDK — one of the most-starred AI coding agents on GitHub.

Build AI-powered apps locally with your own keys, your own models, and zero cloud lock-in.

Index any codebase into an interactive knowledge graph and give your AI agents deep architectural context via MCP — with zero servers required.

"A coding agent that never compacts" — a terminal-based AI coding agent built on the Mastra framework, with Observational Memory instead of context compaction, multi-model support, and OAuth login for Claude Max or ChatGPT Plus.

One unified interface to orchestrate Claude Code, Codex, Copilot, OpenCode, and Pi agents in parallel from desktop, mobile, or the terminal.

A self-hosted, AI-powered code search engine that indexes every repo across GitHub, GitLab, Bitbucket, Gitea, Gerrit, and Azure DevOps, so both engineers and coding agents can search, browse, and ask questions about your codebase from one place.

An open-source AI coding assistant that coordinates specialized agents to edit your codebase from natural language — including Freebuff, a free, ad-supported version powered entirely by open-source models like DeepSeek and Kimi.

A memory-first coding agent harness that learns from experience, maintains identity across models, and works across Claude, GPT, Gemini, and dozens more LLMs.

Run Claude Code workflows against any LLM — OpenAI, Gemini, Ollama, and 200+ backends — from a single terminal-first CLI.

Orchestrate an army of AI coding agents—Claude Code, Codex, Gemini CLI, and more—running simultaneously in isolated git worktrees from a single Electron desktop app.

An open-source Agent Development Environment that orchestrates fleets of parallel AI coding agents — Claude Code, Codex, Gemini and more — each running in its own isolated git worktree.

A single-binary, terminal-native coding agent that reads, edits, and runs code end to end, built by Moonshot AI for Kimi models but pluggable with Anthropic, OpenAI, and Google providers too.

A desktop IDE built on an infinite canvas — spread code editors, terminals, browsers, docs, and AI agents across freeform space instead of stacking windows and tabs, with layouts restored automatically.
