developer tools

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.

Ridge is a resource mesh for AI agents, with MCP, CLI, and Python access to local projects, Docker, SSH machines, and S3 storage. It focuses on delegated resource access, job coordination, and keeping artifacts out of model context.

Botbin is a pastebin-style publishing tool for AI agent artifacts. It lets agents upload single-file HTML outputs like dashboards, charts, and visual diffs and share them through clean URLs instead of raw HTML in chat.

A capability-based microkernel written in SPARK Ada and formally verified with gnatprove, with a thin C SDK for building services and distribution components.

React hooks for exposing app functionality as WebMCP tools, with Zod-based inputs, SSR-safe behavior, StrictMode safety, and a bridge to AI clients like Claude and Cursor.

A serverless reverse geocoding SDK and browser experience for web and embedded devices, with support shown for WebMCP and embedded targets like RP2040, RP2350, and ESP32.

Live demo of a prompt-injection defense for LLMs using per-position semantic overlays. The page shows how marked spans can be treated as untrusted while the base model stays frozen, with interactive examples for retrieved text, hidden instructions, language marking, and request-scoped overlays.

Keel is a Rust CLI harness for AI-assisted coding workflows. It adds auditable stopping conditions, durable memory, projections into agent instruction files, and reviewable gates with exported evidence.

A long-form technical guide on running local LLMs in the browser, with checks for WebGPU support, model hashes, tokenizer matching, and browser-side data leakage.
