Multiplayer is a local debugging agent for developers that connects coding agents to production data so they can fix application bugs automatically. The site highlights runtime debugging, issue deduplication, and integrations with tools like Claude Code, Codex, and Copilot.

A Claude Code skill pack with 171 structured reasoning methods drawn from historical thinkers, designed to route different problem types to specific procedures.

An experimental programming language and compiler built for agent workflows, with CLI commands for parsing, checking, graphing, repair planning, and JSON-based inspection output.

Rust TUI for browsing local Codex and Claude Code session logs, searching past chats, and estimating API-equivalent cost.

Desktop app for orchestrating crews of local coding agents like Claude Code and Codex in one workspace.

An early-access TypeScript rewrite of Prisma ORM built to be extensible, composable, and AI-agent friendly, with scaffolding, agent skills, and extension support.

An Android-focused on-device AI agent fork that can automate phone actions, run workflows and schedules, and be controlled locally or through Telegram.

Open-source package manager for AI coding assistants that helps teams share, version, and scope skills, MCP configs, commands, and other AI assets across tools and projects.

A governance plugin for OpenClaw that registers instances with a Recursant registry and intercepts tool calls, LLM prompts, and chat messages for auth, PII redaction, rate limiting, and auditing.

HookGuard is a CLI security scanner for AI coding agent configuration files. It looks for malicious hooks, invisible Unicode, credential exfiltration patterns, and prompt-injection text in files like CLAUDE.md, AGENTS.md, Cursor rules, and GitHub Copilot instructions.

Single-binary viewer for HTML reports generated by AI agents, with local browsing, live previews, search, and shareable links.

Free analyzer that reads server logs to identify AI bot traffic, estimate bandwidth cost, and generate block rules for Cloudflare, Nginx, Next.js, or robots.txt.

Modular framework for building trading systems with a C++ core, polyglot strategy bindings, and an MCP server for AI coding agents.

Lowdefy is a config-first web stack that lets AI generate reviewable YAML for full-stack apps and can run AI agents that call existing endpoints as tools.

A multi-lens code review pipeline for Claude Code that runs parallel review passes, validation gates, optional Codex review, an auto-fix loop, and interactive walkthroughs for findings.

Rig is a macOS sidecar for Ghostty that helps engineers create, focus, arrange, and track terminal sessions across projects and coding harnesses. It manages real Ghostty windows with AppleScript and macOS Accessibility APIs, and includes a demo plus build/release scripts.

Aion is a collaborative coding game where AI agents propose code diffs to a live game, vote on changes, and ship the winning diff server-side. It includes an MCP endpoint so agents can connect, read the rules, clone the repo, and submit proposals.

A Node.js proxy server that rotates API keys for LLM APIs like OpenAI and Gemini when rate limits are hit. It also includes an admin panel, request logging, provider management, and a Telegram bot for chatting with configured models.

Lightweight AI inference engine written in Rust for embedding local LLMs in mobile and desktop apps, with bindings for Python, Flutter, and React Native.

A hands-on workshop repository that walks developers through building a small GPT-style language model from scratch, including tokenization, transformer blocks, training, and text generation.

Hapsland is a developer tool that gives coding agents realtime semantic review on code changes, with privacy-aware request scoping and feedback loops back to the agent.

HDTP is a protocol specification for agent-to-agent communication on behalf of people, centered on certificates, contact approval, per-caller permissions, and sealed end-to-end calls.

Portia is a copilot for data work that connects to warehouses or local files, profiles tables, answers questions, draws charts, and builds dbt-shaped SQL with step-by-step review. It also ships as a Claude Code plugin and keeps a journal of decisions, checks, and lineage.

An MCP server and API that checks documents for hidden or invisible text before an AI assistant reads them.
