Built from each tool's listing. Vendors can update their own listing after claiming it.
The control plane for AI coding agents.
AI DevKit is an open source command line tool that acts as a control plane for developers running several AI coding agents at once. Rather than replacing Claude Code, Codex, Cursor, Gemini CLI, opencode or Pi, it sits above them and gives them one shared configuration, one console, local memory, a way to pass work betw...
Self-hosted mobile terminal for coding agents on herdr (or tmux/zellij).
ColliePWA is an open source, self hosted web app that puts terminal coding agents on your phone. It mirrors agent panes running in a terminal multiplexer, with Herdr as the primary backend and experimental support for tmux and Zellij, so developers can see which agents are waiting, read the screen and reply from anywhe...
Open-source AI coding agent for the terminal.
KlaatAI, whose terminal coding agent is called KlaatCode, is an AI assistant that routes each request to one of many models under a single subscription. The vendor states that the router covers 47 models from 15 labs and picks the cheapest tier that can handle the task, with automatic failover when a provider has an ou...
Open-source cross-agent memory layer for coding agents via MCP.
Memorix is a local first memory layer for coding agents. It records the decisions, code context and stopping points of a coding session so that a new session in the same project can continue where the last one ended, instead of starting with a blank context. Working sessions are captured as source labelled memories ra...
Run Claude Code, Codex, and Gemini side by side — each in its own git worktree
Parallel Code is a free, open source desktop workspace for running several AI coding agents at once. It supports Claude Code, Codex CLI, Gemini CLI, Copilot CLI and Antigravity CLI. Each task gets its own git branch and worktree, so agents work in separate working copies, and the user inspects each diff and changed fil...
PiG (Pi in Go) is a faithful Go port of upstream Pi, the TypeScript codebase behind the Pi coding agent.
This project is a Go implementation of Pi, an open agent harness for working with AI models from the terminal. It ships as a single binary named pig and aims to carry Pi's behavior, architecture and user experience into the Go ecosystem, while Pi itself remains the reference implementation. The site says compatibility ...
