developer tools

MCP server for Unreal Editor that exposes a small MCP surface for a large set of editor automation tools. It supports blueprint editing, asset management, animation authoring, trace analysis, PIE actions, and Python execution, with setup notes for Unreal Engine 5.x and MCP-compatible clients.

Conan is a native macOS app that adds a live HUD around Claude Code, showing prompts, tool calls, skills, context usage, and session activity in real time. It’s a paid one-time purchase for Apple silicon Macs.

Offline duplicate-code detector for codebases where AI agents write most of the code. It scans for structurally duplicated functions, tracks duplication over git history, and can fail CI when new code repeats existing logic.

A fail-closed execution firewall for AI agents that quarantines MCP tools, proxies OpenAI-compatible requests, and emits signed receipts for offline verification.

dbmachine turns a Postgres database into a self-describing backend that AI agents can operate through a CLI and YAML spec. It compiles schema, constraints, RLS, audit logging, and custom operations into a local Postgres setup.

A free AI-readiness audit tool for Shopify catalogs that scores product visibility for AI shopping agents and flags catalog issues like weak titles, short descriptions, missing attributes, and sparse images.

A black-box benchmark report on how AI-generated tests detect functional bugs in live APIs across 20 scenarios and 7 systems.

Ouijit is an open-source task and terminal session manager for coding agents. It adds agent status, notifications, automatic worktree management, and VM sandboxing, with support shown for Claude Code, Codex, and Pi.

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.

A daily AI intelligence journal for builders, covering notable model, tooling, and release updates in a short sourced digest.

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

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.

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 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.

Local codebase indexer and MCP server for Claude Code that watches project files, builds a private index on-device, and serves relevant snippets to Claude and other MCP clients.

A structured guide to 925 developer tools for AI coding agents, with use-when/avoid-when logic, alternatives, constraints, and health metrics.

A Cloudflare Worker that notifies you when visitors arrive from AI assistants like ChatGPT, Perplexity, Gemini, Claude, Copilot, or Grok, with optional alerts for AI crawlers.

A single-binary OpenTelemetry trace generator that simulates realistic microservice and AI-agent traces, with chaos injection and multiple topology sizes.

An open-source enforcement layer for AI coding agents that adds frozen specs, tamper-detected tests, independent verification, and hard-blocking gates so unverified work cannot pass.
