CopilotHub is a discovery and reference site for developers who already use GitHub Copilot and want to get more out of it. Instead of hunting through blog posts for prompt ideas, you get a structured catalog: curated prompts organized by language or framework (React, TypeScript, JavaScript, Tailwind, SQL, Next.js and more), reusable instruction sets that apply best practices automatically, specialized agents, and a directory of MCP servers and extensions that extend what Copilot can reach.
The site's flagship feature is its Migration Hubs. These are production-oriented playbooks that bundle guides, prompt sequences, and workflows for upgrading real codebases — for example moving a Spring Boot 2 application to Spring Boot 3 with Jakarta EE and Hibernate 6, or migrating Next.js Pages Router projects to the App Router. Each hub is split into discrete prompts you can copy and run, so a large refactor becomes a checklist of small, reviewable AI-assisted steps.
Every entry is tagged and copy-ready, and the catalog is browsable by technology, category, or use case. Sign-in is handled through GitHub, and much of the underlying content is contributed by the community and open for contributions. The platform is free to browse and use; there is no paid tier advertised.
