Open source. Open possibilities.

DevPod is a client-only, open-source tool for creating reproducible dev environments via devcontainer.json on any backend—local Docker, remote machines, Kubernetes, or cloud VMs—working with any IDE.

An unofficial Windows desktop host for DeepSeek Harness: open local Git repositories, keep persistent sessions, control the running agent, review real diffs, recover code checkpoints and use bundled Office and Wiki tools — shipped with pinned Node.js and Harness runtimes.

Reflex is a library for building full-stack web applications using pure Python, eliminating the need for JavaScript for frontend development.

Smokey is a static single-file dashboard that shows GitHub repository health at a glance: last push, latest release, open PRs and issues in one sortable table, plus attention badges for external contributor activity. No login or build step is needed for public repos.

DevMate provides a local-first agent runtime for ChatGPT via MCP, enabling Codex-like file editing, Git operations, and automation in VS Code and Obsidian.

Context Engineering Protocol provides AI coding-agent skills that assemble human-approved, source-attributed context packages — code graphs, requirements, org conventions, and constraints — before generation runs. It detects gaps, conflicts, and staleness across sources, gates output behind explicit human approval, and supports Claude Code, GitHub Copilot, Cursor, and OpenAI Codex.

TangleClaw is an AI coding session orchestrator for macOS that wraps Claude Code, Codex, Antigravity, Aider, and OpenClaw sessions in persistent tmux processes. It provides session continuity, structured wrap summaries, searchable history, secure remote access via Caddy, inter-session agent messaging, and a dashboard PWA — all with zero npm dependencies.

Lighthouse is an open-source tool for auditing web apps and pages to collect modern performance metrics and insights on developer best practices.

Posting is a terminal-based HTTP client in the spirit of Postman and Insomnia. It stores requests as plain YAML files, works over SSH, and supports environments, autocompletion, tree-sitter highlighting, Vim keys, custom themes, Python hooks and cURL/Postman/OpenAPI import.

RAPID is a lean, spec-driven methodology for AI-assisted development, structuring workflows from requirements to delivery with human approval gates.

Simgit provides disk-efficient, isolated Git worktrees using copy-on-write (CoW) for running multiple AI agents or parallel development on a single repository. It leverages native filesystem features (APFS, reflink) or fuse-overlayfs to minimize disk usage, offering significant savings compared to full worktree copies.

JSON Hero is an open-source web-based JSON explorer that lets you browse, search, and navigate JSON files through multiple view modes with content previews and related value scanning.

Divebell is an extensible web development and debugging toolkit for coding agents. It connects page context, browser capabilities, and existing development tools, enabling agents to reproduce, diagnose, and verify web application issues directly in real scenarios via a CLI and extensions.

Karate is an open-source test automation framework that unifies API testing, mocks, performance testing, and UI automation into a single tool.

An unofficial Codex Skill for repository delivery: it routes work between the current task, internal agents and optional App tasks, with explicit ownership, isolated Git worktrees, independent review, an installer with check/dry-run modes, and deterministic tests.

GeeksPulse is a free, ad-free developer news aggregator that curates 50 hand-picked RSS feeds across 11 categories into a fast static site with a cyberpunk UI, AI summaries, bookmarks and keyboard shortcuts.

CodexShell is a desktop shell based on Tauri + React + TypeScript, providing a Codex-style four-column layout, draggable panels, theme and language switching, and other UI framework features. It is not tied to any specific business, allowing developers to integrate their own AI tool functionality.

UCloud SDK for Node.js: a client library for calling UCloud cloud APIs from Node.js. The README links Chinese-language guides on quickstart, configuration, error handling, middleware and generic calls, plus examples for batch-creating cloud hosts and building a two-tier load-balanced architecture.

Swarm is a local-first control plane for AI-agent development that monitors every Claude Code, Codex, Gemini, Grok, Aider, and opencode session on your machine — tracking live tool calls, token spend, cost, tasks, worktrees, and resources — with rules enforcement, a coordination ledger, and a unified dashboard.

Gateship is a local-first delivery runtime for coding agents. It gives a task an isolated Git worktree, runs a local Claude Code or Codex session, verifies acceptance commands, adds an independent read-only review, and ships a squash-merged pull request. State lives in local SQLite, served by a Bun web UI on 127.0.0.1.
