prompts.chat: The World's Largest Open-Source Prompt Library (167,000 Stars)

Two years ago, it was a simple GitHub list called “Awesome ChatGPT Prompts”. Today, it has become the world’s largest open-source prompt library – with over 167,000 stars, 21,600 forks, and its own web app at prompts.chat.

prompts.chat is not just another GitHub repository with a static list of prompts. It is a fully-fledged Next.js web application that allows you to browse, discover, share, and collect prompts. And the best part: You can self-host the entire platform – with complete data sovereignty.

What is prompts.chat?

The project was started by Fatih Kadir Akın and has evolved from a simple awesome list into one of the most influential prompt collections in the world. It is cited in Forbes, referenced by Harvard and Columbia, and has over 40 academic citations.

The range of prompts is enormous – from “Act as a Linux Terminal” to “Act as a Career Counselor” to specialized developer prompts. The community has submitted thousands of prompts, sorted by category and searchable.

Why 167,000 Stars?

1. Quality over Quantity
Every prompt in the collection is reviewed by the community. There is no SEO spam, no AI-generated filler prompts. The collection is curated and focused.

2. Works with every LLM
Unlike many specialized collections (that work only for Claude or only for GPT), the prompts from prompts.chat are compatible with ChatGPT, Claude, Gemini, Llama, Mistral, and all common models. This makes them universally usable.

3. From Harvard to Forbes
The academic and media recognition is exceptional: Harvard University and Columbia University reference the collection in their guides, Forbes has called it an indispensable resource. This builds trust and visibility.

4. MCP Server for Coding Agents
prompts.chat offers an MCP server (Model Context Protocol) that can be directly integrated into coding agents. In 2026, this is the decisive factor: coding agents can retrieve prompts at runtime instead of storing them locally.

The Technical Platform

The repository contains more than just prompts – it is a complete web application:

The MCP server is particularly exciting: You can integrate prompts.chat directly into Claude Code, Windsurf, or other MCP-capable tools – without manually browsing the website:

"mcpServers": {
  "prompts.chat": {
    "url": "https://prompts.chat/api/mcp"
  }
}

Self-Hosting for Companies

Perhaps the most important aspect for companies: prompts.chat can be completely self-hosted. You install the platform on your own servers, your prompt library stays internal. This is GDPR-compliant and gives you full control over the content.

git clone https://github.com/f/prompts.chat
cd prompts.chat
cp .env.example .env
docker compose up -d

After that, your own prompt library runs on an internal URL – with the same features as the public platform.

Dual Licensing

An interesting detail: prompts.chat uses a dual licensing model:

• Source code and site content: MIT License
• Prompt content and data (CSV, PROMPTS.md): CC0 1.0 (Public Domain)

The prompts themselves are therefore public domain. You can copy them, share them, use them in your own projects – without restrictions.

Who is this interesting for?

• Developers: The prompt collection as a reference for everyday work, plus MCP server for coding agents
• Teams: Self-hosted prompt library for consistent prompts across the entire team
• Companies: GDPR-compliant, internal prompt management without external dependencies
• Prompt Engineers: Inspiration and comparison options for their own prompts

What I particularly like

The evolution from “Awesome ChatGPT Prompts” to prompts.chat shows how far the topic of prompt engineering has come in two years. From a static list, it became a platform with its own infrastructure, API, MCP server, and enterprise self-hosting. This is open-source development at its best: a project that grows with its users.
