developer tools

A prompt-injection capture-the-flag arena for testing how AI agents behave under attack. Users can play challenges, create guarded agents, add optional guards and sandboxed tools, and track scores on a leaderboard.

AI-powered security scanner for modern web apps that combines SAST, DAST, and LLM-assisted code review in a single command. The repository includes install steps, quick-start commands, supported stacks, and examples for scanning live URLs or source code.

Openbenchmarks is a public benchmark site for agents comparing SaaS and AI vendors with verified ground truth, open methodology, and metrics focused on build-vs-buy decisions. The snapshot shows benchmark sets for lookalikes, text-to-speech, and speech-to-text, plus links to open data and code.

A Zot docs page describing portable .zot files for packaging agent behavior, skills, requirements, and permissions. It includes manifest structure, file layout, permission rules, and packaging/running examples.

Tokenstead helps people match AI models to their own hardware, with support for Macs, GPUs, and custom rigs. It shows which models can run locally, estimates speed, compares cloud pricing, and includes a source-cited tracker of organizations using different models.

Self-hosted LLM gateway for cost-aware model routing, spend tracking, and policy-based traffic control across multiple providers.

Soup is a Python library that routes Agent Skills into LLM prompts, injecting only the skills relevant to each request. It supports local skills, remote repositories, and multiple providers including OpenAI, Anthropic, Gemini, Ollama, LiteLLM, and LangChain.

A data-driven page that tracks well-known AI agent repositories with no recent public commit signal, comparing star counts with liveness to surface projects that have gone quiet.

Heckle is a QA copilot for agentic app development. It lets you describe a bug in plain language while you use the app, then packages browser context like DOM, console, network, and path details for a coding agent to fix.

Brick is an AI model routing gateway that sends each query to the most suitable LLM based on capability and complexity. The repository includes quickstart steps, Claude Code integration, an OpenAI-compatible endpoint, and a short explanation of when to use it.

An MCP server that lets two Claude agents connect through a short-lived, end-to-end-encrypted tunnel so they can collaborate directly without a human copy-pasting between chats.

Local-first web console for creating, configuring, monitoring, and operating Dockerized Hermes AI agents across one or more trusted machines. The repo includes setup steps, runtime requirements, screenshots, and a detailed feature list covering agent management, provider defaults, credentials, chat, VNC, terminals, bac

Standalone Playwright CLI for AI agent browser automation. It provides a real Chromium browser with structured commands, persistent sessions, token-optimized screenshots, and an eval escape hatch for custom interactions.

A dynamic MCP server that turns JSON configs into callable API tools, with lazy tool discovery, hot reload, and a hosted console/registry.

A Rust CLI and MCP server for orchestrating multiple coding agents, fusing their answers, and resuming or routing agent sessions locally.

Caplets is a developer tool that wraps MCP servers into smaller capability-based surfaces for coding agents. The site explains the workflow, setup, example capabilities like OSV, GitHub, and Sourcegraph, and includes benchmark results plus docs links.

Ponytrail is a CLI and bundled agent skill for tracking why files changed, viewing a local history tree, and reverting snapshots in AI coding workflows.

An open-source Claude skill that runs structured retrospectives after sessions, applies improvements to the right layer of your Claude setup, and keeps a dated audit log of changes.

Platinum.ai creates AI Website Profiles in llms.txt format so businesses can be read more easily by ChatGPT, Claude, Gemini, and other agents. The page includes a live scan CTA, a simple three-step workflow, industry examples, and pricing starting at $99.

Go packages for building agents in Go, with a streaming runner, tool dispatch, guardrails, compaction, provider adapters, and verified completion helpers.

infer0 lets users connect their own AI provider keys and authorize apps to use them, while developers integrate once and route requests through a provider-agnostic API layer.

Ponytail is a repository and plugin toolkit that pushes AI coding agents to choose the smallest useful implementation first, favoring stdlib, platform features, and one-line fixes over larger generated code. The README shows installs and usage paths for Claude Code, Codex, OpenCode, Cursor, Windsurf, Cline, Copilot, Ai

macOS CLI tool that load-balances Claude Code sessions across multiple subscriptions by selecting the emptiest account before launch.

Workplane lets users publish Markdown, HTML, PDFs, and screenshots as shareable pages for humans and agents, with comments, versioning, and MCP-based publishing from AI tools.
