AI tool

A local terminal UI for exploring AI coding spend across tools like OpenCode, Claude Code, Codex, GitHub Copilot, and more. It shows costs by month, day, project, session, and model, with drill-down views, heatmaps, exports, and a web browser mode.

Open-source runtime for coding agents that sits underneath Claude Code to reduce tool calls, shorten context, and track savings. The page includes installation steps, a local savings check, and benchmark results comparing cost and performance.

UnderstandDocs is a document analysis tool that summarizes pasted text or uploaded files, flags risks, extracts important dates, and simplifies dense language. The page shows a working analysis form, supported file types, a privacy/no-storage claim, and an example output for a tenancy agreement.

A visual benchmark that asks AI coding agents to generate a single-file Three.js animation of a banana plant’s full life cycle, then compares the live results side by side.

A free open-source Mac app that lets non-coders enable and manage Claude Cowork skills and personas through a switchboard-style UI.

An MCP server that gives coding agents a compiler-backed graph of a TypeScript codebase, so they can answer structure questions with fewer tokens and exact file-and-line references.

A from-scratch ~1B parameter language model on Hugging Face with open weights, open data, training details, and loading guidance. The page is unusually candid about capabilities, limits, and evaluation.

A TypeScript library for deterministic context folding in long-running LLM agent sessions, designed to preserve prompts, avoid extra summarization calls, and keep provider caches hot.

A deterministic Python project for empirical law discovery in elementary cellular automata, with simulation, discovery, reproducibility guides, and published preprints.

Tecture helps coding agents write and maintain architecture docs directly in the repo, then lets teams explore them as interactive diagrams in VS Code or the browser.

Recall is a local-first memory tool for Claude Code that logs sessions and generates a compact project summary offline, without sending data to an API.

Rust-based PostgreSQL MCP server with 135 tools for Claude Desktop and other MCP-compatible AI tools. Supports stdio, TCP, and HTTP/2 transports, plus quick-start install and setup instructions.

NILScript is an open standard and CLI toolkit for letting AI agents act on real systems through a gated propose → approve → commit → rollback flow. The page shows a live playground, quickstart commands, and benchmark claims around unauthorized writes.

A macOS menu bar app that helps users pace Claude Code and Codex usage against weekly and 5-hour quota windows.

A Rust-based checker that compares a changed function against its prior version on deterministically generated inputs and reports counterexamples when behavior changes. It includes a PR gate via GitHub Actions, CLI usage, signed receipts, and docs for release/signing.

An MCP server for SharkClean and SharkNinja robot vacuums that lets MCP clients start cleanings, target rooms, dock the robot, and check status. The repo also includes setup steps, authentication guidance, CLI commands, and notes on supported models and cloud backend behavior.

Open-source AI-powered desktop automation agent that gives an LLM a fully isolated Ubuntu workspace with browser-based supervision, MCP access, audit logs, and OS-level control.

Open-source agentic end-to-end browser testing tool for web apps. It runs JSON-defined test journeys in Docker and can be used as a CLI or optional self-hosted web app.

Nanocode is a terminal-based AI coding assistant written in Python. The repo shows CLI install and usage instructions, runtime commands, configuration options, supported providers, and a detailed description of its context and file-editing workflow.

Open-source interface for running coding agents from phone, desktop, web, and CLI. Supports multiple providers, runs locally on your own machine, and includes a daemon plus client apps.

A pure-Python LLM inference engine and server with CUDA/HIP/Metal code generation, OpenAI-compatible API support, built-in RAG, and multi-GPU backend support.

An open-source ecommerce starter that boots a Magento or Mage-OS store in GitHub Codespaces and uses Claude to make changes directly in the live dev environment.

SnapName is a macOS app that watches a screenshot or image folder and uses bundled local AI to suggest better filenames without uploading images.

tokentoll is a GitHub Action and CLI that scans Python and JavaScript/TypeScript code for LLM API calls, estimates spend, and blocks pull requests when cost or model-policy thresholds are exceeded.
