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.

An open NDJSON specification for AI crawler ingestion and site content graphs, with examples and reference files in the repository.

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

A tiny GPT implementation in pure Go, trained on Jules Verne books, with runnable code and notes that explain the model’s evolution and design choices.

A loopback HTTPS proxy that swaps placeholders for real API keys at request time, keeping secrets out of the agent process. It uses Bitwarden Secrets Manager and supports scoped bindings for hosts, methods, and paths.

Swift package for building provider-agnostic AI agents on Apple platforms, with tools for runtime permissions, hooks, context compaction, session state, validation loops, and traceable execution.

Open-source estimation tool for AI coding-agent tasks. It gives PERT-based time forecasts, human-speed comparisons, model reliability checks, and wave planning for parallel work.

An interactive lab for tracing how AI-assisted engineering workflows can reach repos, CI/CD, credentials, tools, approvals, and proof trails.

A session manager for AI coding agents that lets developers run and monitor multiple agents in parallel from a TUI or web dashboard. It supports several agent frameworks, uses git worktrees and optional Docker sandboxes, and includes remote phone access plus PWA-style web use.

WUPHF is a local-first AI agent workspace that runs a team of role-based agents with a shared wiki and persistent project memory. It supports Claude Code, Codex, OpenClaw, and local models via OpenCode, with install and build options shown on the page.

A CLI for structural code search and refactoring using AST patterns instead of regex. It supports find, replace, delete, and insert workflows, with examples for method renames, logging removal, and code inserts across files.

Stage CLI is an AI-powered code review tool that groups local changes into logical chapters and helps users review what matters before diving into the code. It works with any AI agent, installs via npm, and can be invoked as a local command to open a browser-based review UI.

Lightport is a lightweight AI gateway that makes LLM providers OpenAI-compatible. The repo shows supported endpoints, a long provider list, quickstart commands, request examples, and active maintenance signals.

A persistent memory layer for AI agents, built as a standard MCP server with local setup, dashboard, and benchmark claims against other memory tools.

Ante is a self-contained coding agent that runs in your terminal, supports local models, and offers CLI, TUI, server, and gateway modes. The page highlights public benchmarks, low resource usage, and support for multiple providers and agent orchestration.

Sentrint is a security scanner for apps built with LLM platforms like Bolt, Cursor, and v0. It scans repos for secrets, access rules, vulnerable dependencies, and risky code paths, then returns plain-English findings and a copy-paste fix prompt.

A CLI bridge that wraps legacy MCP stdio servers so they can run behind the newer stateless 2026-07-28 protocol. The page includes a concrete usage example, client configuration snippets, compatibility behavior, and known limitations.

An out-of-tree vLLM plugin that compresses KV cache with STAR-KV to fit more concurrent requests and longer contexts on the same GPU memory budget.

A Vale style pack that lints prose for AI-like writing, inspired by ASD-STE100. It helps teams catch buzzwords, vague phrasing, self-praise, and other patterns in docs, comments, and agent-authored text.

A Git-backed CLI for sharing agent skills, settings, and MCP fragments across repositories with per-project lockfiles and update workflows.

DSCode is an open-source coding agent for working in real repositories from the terminal. It supports install via npm, connects to DeepSeek, and highlights local sessions, sandboxed commands, parallel agents, and cost tracking.

PipeCrab is an open-source Rust pipeline for building voice agents, with local inference support and examples that show end-to-end audio, transcription, LLM, and TTS flows.

A Lean 4 project for formally verified 3D mesh intersection and constructive solid geometry, with a browser demo for intersecting example meshes or STL imports.

A language server for agent skills that turns /skill-name and $skill-name into navigable symbols with completion, rename, go-to-definition, and reference tracking across editors like VS Code, Zed, Neovim, and Helix.
