TypeScript

firebase/firebase-tools

Firebase CLI now doubles as an MCP server for AI coding agents — The long-standing Firebase CLI for deploying, testing, and managing Firebase projects now bundles an official MCP Server, letting AI assistants query and act on Firebase resources directly. It also integrates with Firebase agent skills, giving coding agents built-in knowledge of CLI commands and best practices.

The Firebase Command Line Tools

shuaiplus/nodewarden

Bitwarden-compatible server running on Cloudflare Workers

aws/aws-sdk-js-v3

The modular, TypeScript-first rewrite of AWS's JS SDK — AWS SDK for JavaScript v3 splits the monolithic v2 SDK into per-service packages, so you only install what you use. It adds first-class TypeScript types and a redesigned middleware stack, with official migration guides and sample apps for teams moving from v2.

Modularized AWS SDK for JavaScript.

amosblomqvist/learnharness

An AI tutor that maps your reasoning before teaching you anything — LearnHarness is an agent harness that diagnoses exactly where your understanding ends, plans a dependency path to your goal, and teaches step by step using your own answers and reasoning. A persistent knowledge graph tracks progress across sessions, and separate practice sessions adapt problems to how you think, aimed at learners of hard technical material.

Agent harness for learning difficult things.

stack-chan/stack-chan

Browser-flashable, MOD-friendly firmware for a JavaScript kawaii robot — Stack-chan is an open-source M5Stack robot you can set up entirely from the browser: a Web firmware installer flashes the official M5StackChan CoreS3 without installing the Moddable SDK or ESP-IDF, and a MOD Gallery lets you try or install community apps, including block-based samples editable in-browser. It targets hobbyists who want a cute, hackable JavaScript robot without a local dev setup.

A JavaScript-driven M5Stack-embedded super-kawaii robot.

Chuloo/mural

The language app you eventually delete. A native iPhone companion for learning through conversation.

nrslib/takt

YAML-defined workflows that discipline multi-agent coding loops — TAKT is a CLI that encodes planning, implementation, review and fix loops as YAML workflows, assigning each step its own role, context and transition rules rather than relying on one agent to remember everything. It runs tasks in isolated worktrees with traceable logs and human checkpoints, aimed at teams tired of babysitting AI coding agents like Claude Code or Codex.

TAKT Agent Koordination Topology - Define how AI agents coordinate, where humans intervene, and what gets recorded — in YAML

darula-hpp/shimmer-from-structure

A structure-aware skeleton loader that mirrors your rendered UI at runtime. Zero layout duplication. Built for modern frameworks.

supermemoryai/company-brain

Open-sourcing our company brain - A teammate in your Slack that remembers everything your team says, and can go do the work.

cloudflare/mcp

A Cloudflare MCP server that shrinks 2,500 endpoints to 1k tokens — This MCP server exposes the entire Cloudflare API using Code Mode, cutting context usage from ~2M tokens (raw OpenAPI) or ~1.17M tokens (native MCP schemas) down to roughly 1,100 tokens with just 3 tools. It supports OAuth or API token auth and targets agents needing broad Cloudflare control without blowing their context window.

MCP server for the Cloudflare API

WowUp/WowUp

WowUp the World of Warcraft addon updater

AnkioTomas/qqpet

QQ宠物单机复刻版(AI)

phantomptr/ps5upload

Resumable uploads and remote management for jailbroken PS5s — ps5upload sends games, apps and homebrew to a jailbroken PS5 with resumable transfers over an encrypted AVA1 connection, automatic fallback between install routes, and a collection view across files. It works from macOS, Linux, Windows, Android, iPhone or a browser, covering PS5 firmware 1.00–14.10, making it useful for anyone managing a jailbroken console remotely.

Send games, apps and homebrew to a jailbroken PS5, and manage the console from your computer, phone or browser.

wokwi/avr8js

The AVR core engine powering browser-based Arduino simulation — avr8js is a JavaScript/TypeScript implementation of the AVR 8-bit CPU core, best known as the engine behind the Wokwi Arduino simulator. It only emulates the CPU, so developers must supply compiled firmware and build their own hardware simulation and visuals, optionally pairing it with the wokwi-elements component library. Useful for anyone building custom browser or Electron-based Arduino simulators and educational tools.

Arduino (8-bit AVR) simulator, written in JavaScript and runs in the browser / Node.js

surendrapandar/minilytics

Opensource Revenue-first analytics for indie hackers & solo founders

l0ng-ai/openidea

The IDE you know, rebuilt in Rust. IntelliJ IDEA–style keymap, tool windows and search-everywhere in a fast native app: editor, code insight, debugger, Git, terminal, database and HTTP clients for 60+ languages.

iamlukethedev/Herald-OS

An OS layer where an AI agent, not menus, runs your machine — Herald OS wraps a desktop around Hermes Agent, the open-source agent from Nous Research, so you talk to it instead of clicking through folders. It opens apps, organises files, watches running processes, runs scheduled routines, and even builds software, all gated by a permission system you control. It's an independent alpha project, unaffiliated with Nous Research.

An agent-native operating system, with Hermes Agent as the interface. Independent project, not affiliated with Nous Research.

agharsallah/esp-labs-web

The ESP32-S3 bench guide as a React app: live pinout, lessons with interactive simulators, a code reader for the esp-labs firmware, and the bench log. In 11 languages.

aerovato/container

Persistent Linux workspaces for agentic development.

qitechgmbh/control

A Rust & React alternative to proprietary PLC software — QiTech Control replaces licensed, point-and-click PLC ecosystems with an open-source stack: a Rust backend driving EtherCAT terminals (WAGO, Beckhoff) via Ethercrab, paired with an Electron/React frontend and a realtime NixOS build. It targets developers and industrial automation teams who want modern tooling instead of rigid vendor workflows.

Next Generation Machine Interface

FrigadeHQ/hob

Local AI desktop app that auto-picks the right open-weight model for your Mac — Hob is a free, open-source desktop app that runs open-weight models like Gemma and gpt-oss locally via llama.cpp, offering offline, private alternative to Claude and ChatGPT. It automatically selects the best frontier model that fits your hardware and sets up everything, letting you fill PDFs, analyze documents, and chat without sending data to the cloud.

An easier way to use AI on your own computer. A free, open-source alternative to Claude and ChatGPT that runs open-weight models like Gemma and gpt-oss locally on Mac, Windows and Linux. Private, and works offline.
