The developer directory for AI coding tools

Q: What tools do you cover?

Every major AI coding tool. Claude Code, Cursor, GitHub Copilot, Windsurf, Codex, Devin, Gemini CLI, and more. Each tool has a profile page with pricing, features, and links to its compatible skills, rules, and agents.

Q: What is an "agent" here?

An automated workflow assembled from components. A code review agent combines a code review skill, a CLAUDE.md rule file, a GitHub MCP server connection, and Claude Code as the platform. The agent page walks you through the full build, step by step.

Q: Is this connected to ClickUp?

Codegen was acquired by ClickUp in 2025. The directory is editorially independent and covers all tools equally. ClickUp provides the workflow layer where agent output like PRs, docs, and test reports gets tracked and managed.

Q: Where should I start?

Choosing a tool? Browse the comparisons. Already using a tool and want to extend it? Browse the skills directory. New to AI coding tools entirely? Read the glossary entry on agentic coding, then pick a comparison to see what is available.

Browse tools, install skills, connect MCP servers, and build automated agents for Claude Code, Cursor, Windsurf, and more.

Skills are downloadable instruction files that teach an AI how to do something specific. MCP servers connect external services like GitHub and Stripe to your AI coding tool. Rules are config files that encode your team's conventions and coding standards. Agents combine all three into automated workflows you run with a single command.
