Open-source self-hosted voice AI agent for Asterisk/FreePBX with Audiosocket/RTP support, a modular STT/LLM/TTS pipeline, and quick-start docs for deployment.

Disposable, network-restricted Linux VMs for AI coding agents. The project is built for letting coding agents install packages, run tests, use system tools, and work inside an isolated machine instead of the host laptop.

Kastor is an open-source Go toolchain for defining AI agents, tools, and prompts in HCL. It treats agents like versioned infrastructure, with build, plan, and apply workflows, code generation for frameworks like LangGraph, and drift-aware management on hosted platforms.

Local browser-control tool that lets coding agents drive a signed-in Chromium browser through a CLI, daemon, and extension.

Rowboat is an open-source desktop AI coworker that keeps long-term memory in a local Markdown knowledge graph and includes built-in surfaces like email, browser, notes, meeting transcription, and code mode.

Excalibur is an open-source AI coding agent for product engineers. It runs from the terminal, supports multiple model providers, and covers the full workflow from discovery and planning through implementation, verification, review, and shipping.

Open-source companion tooling for agentic AI coding, built as a plugin and CLI around Anthropic Claude Code with support for related coding tools. The site shows setup, usage, and many concrete workflows for brainstorming, root-cause analysis, component discovery, decision support, document cleanup, and code analysis.

A drop-in proxy for Ollama that automatically tunes local LLM requests to reduce RAM use and speed up first-token latency. The page shows install steps, benchmark results, a live dashboard, and a local-only admin UI.

Ouijit is an open-source Git worktree-based task and terminal session manager for CLI coding agents, with integrated terminals, lifecycle hooks, session-aware commands, and basic VM sandboxing.

Sipp is a zero-dependency AI inference runtime for running models in the browser and across Node, Rust, Python, and self-hosted gateways. The page shows install commands, a symmetric client API, benchmark claims, and live demos for chat, agents, vision, and game use cases.

HALO is an open-source local debugger and optimizer for AI agent traces. It collects execution traces, analyzes recurring failure modes with an RLM-based engine, and feeds findings into a coding agent to improve the harness.

Open-source AI agent monitoring platform with tracing, issue grouping, evals, semantic search, alerts, and MCP access for coding agents.

An Android accessibility service that lets agents and scripts inspect the UI tree and control a phone from the CLI, REST, or MCP with token-gated permissions.

Velane is an agent-first code runtime for building workflows with AI agents. It connects to Cursor or Claude via MCP, offers 800+ integrations, and lets agents create, test, and promote Bun or Python workflows with sandboxed execution and environment controls.

A self-hostable SMS relay for AI agents that uses an old Android phone and a prepaid SIM, exposed over MCP so clients like Claude, ChatGPT, and Cursor can send and receive real texts.
