Agentize is an open-source tool that lets websites expose a first-party semantic search/index interface for AI agents. It builds a semantic index from owner-selected sources, serves Markdown and canonical URLs from the site’s own domain, and supports local embedding generation.

Self-hosted ebook library that runs on object storage. It can run as a Cloudflare Worker over R2 or as a Node server over a directory, with support for EPUB and PDF reading, search, downloads, profiles, and reading positions.

A Ruby gem that encodes the Vercel AI SDK Data Stream protocol for Rails and Rack backends, so Ruby apps can stream text, reasoning, tool calls, and data parts to useChat/useObject.

Open-source repository for a NanoGPT training speedrun, focused on getting a 124M model to target loss on 8x H100 GPUs in under 90 seconds. The README includes run commands, Docker instructions, and a detailed list of model and systems optimizations.

A portal layer that unifies multiple MCP servers behind one endpoint so AI clients can connect once and use three meta-tools instead of dozens or hundreds of exposed tools.

Meridian is a local-first work journal for developers that reconstructs screen activity into a daily timeline, summary, and draft worklog or standup updates, with ticket drafting for Jira-style workflows.

An open-source MCP server and bench CLI for agent-driven firmware development on physical hardware. It lets coding agents compile, flash, read serial output, debug boards, and manage OTA/fleet workflows for ESP32-class devices.

fx is a tiny open-source coding agent and CLI written in Zig. The page shows it as a minimal, model-agnostic tool built for research, embedding, and low-footprint local or cloud use, with WASM support and a shell-like interface.

A native macOS Postgres GUI that can draft SQL from natural-language questions, using either a configured cloud model or Apple’s on-device Foundation Model on supported Macs.

Waku is a native desktop app for managing local coding agents in one timeline. It supports agents like Amp, Claude Code, Codex, Cursor, OpenCode, Grok, and Pi, keeps data on the user’s machine, and includes checkpoint-based rewind for code and conversation state.

Taurus is a multi-agent AI orchestration platform for building hierarchical agent teams with persistent memory, isolated containers, schedules, and a REST API.

Deterministic retrieval-only Q&A system for documentation that avoids LLM calls at runtime. It uses Gemini embeddings, local Qdrant storage, and a CLI chatbot to answer questions with low latency and near-zero per-query cost.

An Electron desktop app for coordinating AI coding work by feature, using local Markdown cards and Git worktrees. It connects with Codex CLI and Claude Code CLI, tracks agent activity, commits, token usage, and keeps project context inside the repository.

Open-source coding agent for VS Code that can inspect a workspace, plan changes, edit files, run commands, and work with free providers or local Ollama models.

VS Code extension that provides one interface for running multiple coding agents, including Claude, Codex, OpenCode, Qwen, and Hermes, with session history, diffs, permissions, and tool-call visibility.

Open-source Go control-plane proxy for AI agents that enforces identity, policy, budgets, and audit for MCP and other upstreams, with anomaly detection that can auto-block compromised agents.

A Rust CLI that renders terminal text effects as a single static binary, ported with byte-exact parity from TerminalTextEffects. The README explains usage, build steps, supported platforms, and the project’s fidelity/performance goals.

Rust-native desktop cockpit for coordinating multiple AI coding tools like Claude Code, Codex, and Gemini CLI in one interface. The page shows installation steps, supported platforms, core workflows, safety defaults, and release notes.

Open-source governance harness for AI agents with policy enforcement, human approvals, isolated execution, budgets, and signed audit evidence. It includes a CLI, REST API, web dashboard, SDKs, and adapters for common agent frameworks.

A read-only MCP server that lets AI assistants search, browse, and inspect public AI-agent listings from natural language inside clients like Claude and Cursor.

Graft builds a semantic code graph for coding agents so tools like Claude Code and Cursor can understand a repository faster with less re-exploration. It ships as a CLI with agent wiring, graph generation, and visualization, and supports local or hosted model providers.

Lucidos is a local AI OS and companion that keeps described apps running, responds to events, and works from a persistent desktop or browser-based interface. The repo shows install paths for macOS and Linux, a headless runtime, source build instructions, and a clear focus on user-owned local data.

Fast Rust MCP aggregator that exposes a small fixed tool surface for agents while semantically searching and calling tools across many downstream MCP servers. Supports SQLite-backed persistence, restart-safe embeddings, stdio and Streamable HTTP transports, plus a REST API for testing.

An unofficial MCP server for cosmos.so that lets AI clients search, browse, and save visual moodboards. The repo includes install steps, authentication guidance, and concrete examples for Claude Code, Claude Desktop, and Cursor.
