Developer Tools AI Tools

Open-source agentic mesh for governing AI agents across enterprise systems, with identity, policy enforcement, audit trails, observability, and Kubernetes-native deployment.

A CLI for the Slack Web API built for coding agents. It exposes Slack methods through a single command format, supports JSON stdin, dry runs, pagination, and discovery commands, and installs via npm.

Council is a repository for an AI decision-support skill that runs five independent advisors plus a chairman to help an agent weigh architectural, product, marketing, naming, and other multi-perspective decisions.

Viaduct is a C4 modeling tool for software teams that exposes architecture to AI coding agents through a hosted MCP server. It includes live collaboration, change sets, OpenAPI-backed endpoints, sequence diagrams, and Figma integration.

A Model Context Protocol server for inspecting OpenStreetMap data and preparing review-first road edit proposals from local GPX surveys. It supports read-only discovery, previewed edits, and a guarded confirmation flow for production writes.

Aide is an open-source sandbox layer for coding agents that runs on macOS and Linux. It focuses on OS-native permissions, reproducible project configs, capability-based access, and visibility into what the agent can do during a session.

Open-source control room for AI coding agents that shows live edits across a repo, flags collisions, and supports hooks for Claude Code, Codex, and opencode.

Open-source platform for simulation testing and production monitoring of voice agents, with support for simulated conversations, mocked tool responses, graders, and self-hosting.

Anypick is an open library for selecting the best LLM across providers using filters for capabilities, pricing, and benchmarks. It includes Python and TypeScript implementations, provider support for OpenRouter and Vercel AI Gateway, and examples showing how to pick a model by constraints and strategy.

gremlord is a local router that lets Claude Code run on Anthropic, OpenAI, xAI, Ollama, vLLM, OpenRouter, and other OpenAI-compatible endpoints. It adds token metering, hard budget limits, size-aware routing, and model-based session handling while keeping the Claude Code TUI and tools.

Pod is an AI-native review and knowledge-sharing site where agents can search firsthand observations about products, APIs, and services, and contribute their own experiences.

Git-native persistent memory for AI coding agents, built in Go with BM25 search, OKF v0.2 support, and an embedded MCP server for local project knowledge.

Codeknow turns a codebase into a queryable knowledge graph for architecture analysis, impact detection, drift tracking, onboarding tours, and refactoring guidance. It runs without LLM keys, supports 25+ languages, and exposes a broad CLI plus export formats and interactive views.

Keyboard-first desktop Kanban workspace for AI coding agents with embedded terminals, git worktrees, and hook-driven task tracking. It supports workflows for task search, project filtering, notifications, live AI session tracking, and keyboard-driven board control.

OpenCrew is an open-source multi-agent orchestration layer built on Claude Code. It lets users add agents, route work through a Captain orchestrator, review approvals before tools run, and keep full git-style version history for agent configs and runs.

Spewer is a local service for delegating bounded coding tasks to cheaper models, with durable task state and evidence-rich receipts. The repo shows install, ask, background task, watch, check, and cancel flows, plus local Ollama/Qwen3 support.

Grith is an OS-level security supervisor for AI coding agents on Linux. It intercepts syscalls, scores risky actions, pauses ambiguous ones for human review, and can deny dangerous calls before they run.

Open-source agent skill and Python service for stripping AI provenance marks from text and files. It supports multiple hosts, includes install scripts, hooks, and a service-backed workflow for cleaning watermarks across many file types.

Rust library for building modular, scalable LLM applications and agentic workflows. It supports multi-turn streaming, multiple model providers, vector store integrations, and agent runtime abstractions.

OpenSpender gives AI agents a self-custodial wallet so they can pay for model and tool calls with per-request, daily, and total caps. It connects through MCP and supports clients like Claude Code, ChatGPT, Codex, and opencode, with itemized spend and a catalog of x402 and MPP services.

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.
