Top CODING GitHub Repositories & Tools (2026)

An agentic skills framework & software development methodology that works.

A terminal window manager that knows what your agents are doing. Tiling panes, workspaces, sessions that survive restarts, and one Inbox for every coding agent.

Run coding agents without babysitting them. Keep jobs focused, bounded, checked and accountable from start to finish. Finally run your agents swarms overnight and get your time back.

Art and animation, written as code. Illustrations, loops, interactive web art, stickers and scored films in dozens of styles, identical on every render.

Taste-Skill - gives your AI good taste. stops the AI from generating boring, generic slop

the runtime your coding agents live on

Local-first AI coding agent desktop: Electron + Rust host core + pi Agent Harness + user-installable plugins

Graphs that teach > graphs that impress. Turn any code into an interactive knowledge graph you can explore, search, and ask questions about. Works with Claude Code, Codex, Cursor, Copilot, Gemini CLI, and more.

A complete computer science study plan to become a software engineer.

Sketch Material 3 Expressive screens in the browser and turn them into vibe-coding prompts.

CLI proxy that reduces LLM token consumption by 60-90% on common dev commands. Single Rust binary, zero dependencies

Free, open source video downloader for Windows, macOS and Linux that AI agents can drive. Downloads from YouTube, Instagram, TikTok, X, Reddit, torrents and the sites yt-dlp supports. Its MCP server lets Claude Code, Cursor and Codex queue downloads, and it runs Claude Code, Codex, Gemini CLI and Ollama as agents.

from vibe coding to agentic engineering - practice makes claude perfect

HarnessRouter Community Edition: the self-hosted, Apache-2.0 edition of the unified interface for agent harnesses. Run Codex, Claude Code, Hermes, PI, DSH, and more through one API, with sessions, streaming, files, cancellation, and failure handling. Implements the Unified Harness Protocol (UHP), an open standard. Your keys, your infrastructure.

A DeepSeek coding agent harness: persistent shell, Ultra subagents, auto approval, Chrome MCP and session telemetry

🎨 Best DeepSeek Harness Design Plugin. The open-source Claude Design alternative. 🖥️ Local-first desktop app. 🖼️ Your coding agent becomes the design engine: prototypes, landing pages, dashboards, slides, images & video — real files, HTML/PDF/PPTX/MP4 export. 🤖 Claude Code / Codex / Cursor / DeepSeek Harness / OpenCode & 20+ CLIs via BYOK.

PiG (Pi in Go) is a faithful Go port of upstream Pi, the TypeScript codebase behind the Pi coding agent. It is a parity-bound translation, not a rewrite: upstream behavior is the contract, and Go is the implementation language.

Claude Code, Codex, OpenCode, Gemini, and Prime Agent versions of Poteto's pstack. Rigorous agent workflows with Cursor primitives translated for other harnesses.

Skills that translate your coding agent's output into plain language: honest reports, straight verdicts, steps you can follow. MIT.

Omnigent is an open-source AI agent framework and meta-harness: orchestrate Claude Code, Codex, Cursor, Pi, and custom agents — swap harnesses without rewriting, enforce policies and sandboxing, and collaborate in real time from any device.
