open-source

An autonomous research system that runs on a single workstation and aggressively checks its own claims with adversarial self-verification, replication, and calibration audits.

r3 is a local code review tool for AI-generated code and docs, with a browser UI, anchored feedback, and an agent loop for create/watch/reply workflows.

A local terminal UI for exploring AI coding spend across tools like OpenCode, Claude Code, Codex, GitHub Copilot, and more. It shows costs by month, day, project, session, and model, with drill-down views, heatmaps, exports, and a web browser mode.

Open-source runtime for coding agents that sits underneath Claude Code to reduce tool calls, shorten context, and track savings. The page includes installation steps, a local savings check, and benchmark results comparing cost and performance.

A free open-source Mac app that lets non-coders enable and manage Claude Cowork skills and personas through a switchboard-style UI.

Open-source telephony infrastructure for AI agents. AgentLine provides a REST API and MCP server for making and receiving phone calls, handling SMS, and storing transcripts, with Docker-based local setup and a hosted option.

Busabase is an open-source, local-first database and knowledge base built around approval workflows for AI-generated changes. It lets users review, approve, and merge agent-proposed records, and includes a simple API plus desktop, Docker, and source-based setup options.

Kernel-level read gate for AI coding agents that blocks protected file reads before bytes reach the agent, with Linux fanotify and macOS Endpoint Security support.

Open-source AI SQL IDE for databases with a built-in AI data analyst, schema browser, notebook-based query runner, and persistent workspace state.

Open-source N64 game engine and visual editor built with libdragon and tiny3d. It targets real hardware and accurate emulators, with GLTF import, HDR+bloom, big-texture support, scene management, audio, collision, and node-graph scripting.

Open-source SDK and libraries for building local-first, peer-to-peer AI apps. It supports local LLM inference, embeddings, translation, transcription, TTS, OCR, image generation, and an OpenAI-compatible API across desktop and mobile platforms.

Tecture helps coding agents write and maintain architecture docs directly in the repo, then lets teams explore them as interactive diagrams in VS Code or the browser.

An open-source MCP server that returns page-cited, verbatim evidence from embedded and firmware reference docs for coding agents.

Open-source authorization engine for AI agents that adds confidence-based gating, human review, policy-as-code, and audit logging. The repo shows quickstart code, local demo steps, SDK installs, and self-hosting options.

MakerChecker is a self-hosted governance layer for AI agents that enforces roles, approvals, and tamper-evident audit logs. The repo shows quickstart commands, a demo flow, and SDK/connectors for TypeScript, Python, and LangChain-style integrations.

ctx is a local-first desktop workbench for coding agents, now open source under GPL-3.0. The page explains that it runs agents in a desktop environment with worktrees, transcripts, artifacts, diff review, container boundaries, and a local merge queue.

Go-native framework for building, orchestrating, and observing AI agents with native OpenTelemetry, an embedded dashboard, replay, and first-party MCP/A2A support.

An AI API gateway/proxy in Go that sits between coding clients and upstream LLM providers, with request routing, secret redaction, context handling, MCP tool integration, and transparent SSE streaming.

Open-source AI-powered desktop automation agent that gives an LLM a fully isolated Ubuntu workspace with browser-based supervision, MCP access, audit logs, and OS-level control.

Open-source voice-driven multi-agent assistant for building real projects on a Mac, with voice, web chat, and WhatsApp channels plus CLI-based task runners.

Local-first agent OS that lets you run and steer Claude Code, Codex, and OpenCode from a browser or chat app while keeping code and keys on your own machine.

Nanocode is a terminal-based AI coding assistant written in Python. The repo shows CLI install and usage instructions, runtime commands, configuration options, supported providers, and a detailed description of its context and file-editing workflow.

Open-source interface for running coding agents from phone, desktop, web, and CLI. Supports multiple providers, runs locally on your own machine, and includes a daemon plus client apps.

A pure-Python LLM inference engine and server with CUDA/HIP/Metal code generation, OpenAI-compatible API support, built-in RAG, and multi-GPU backend support.
