What is RepoFinder?
RepoFinder is a discovery engine for open source software on GitHub. It helps developers, engineers, and technical teams find the right GitHub repositories — APIs, frameworks, libraries, SDKs, and developer tools — without wading through generic search results.
Every query hits the live GitHub Search API, so you're always looking at up-to-date projects: current star counts, active maintainers, and the languages you actually work in.
Features
Built for the way developers actually evaluate open source projects.
Instant GitHub search
Query millions of GitHub repositories in real time with language, star, and sort filters tuned for developers.
Smart filtering
Narrow results by programming language, minimum stars, or activity to find libraries and frameworks that actually fit your stack.
Bookmarks & history
Save repositories to revisit later and browse your recent searches — your discovery workflow, kept in one place.
Curated categories
Hand-picked entry points into AI tools, APIs, databases, DevOps and more, so you skip the noise and jump to what matters.
Why use RepoFinder?
Choosing the wrong library costs hours — sometimes weeks. RepoFinder shortens that decision loop. Instead of piecing together information from a dozen tabs, you get one place to search, filter, and shortlist open source projects that match your requirements.
Whether you're evaluating AI tools for a new product, adding a payments API, hardening a service with cybersecurity tools, or picking a frontend framework, RepoFinder surfaces the projects that are active, popular, and worth your time.
Popular categories
Jump straight into curated slices of the open source ecosystem.

Frequently asked questions
Is RepoFinder free to use?
Yes. Search, filtering, and category browsing are free. Creating an account unlocks bookmarks and search history — no paid tier required.
Where does the data come from?
RepoFinder queries the public GitHub Search API in real time, so results reflect the current state of open source software — stars, languages, and activity included.
Can I find AI tools and cybersecurity tools here?
Yes. Search terms like 'llm', 'agent framework', 'sast', or 'vulnerability scanner' surface trending AI tools, cybersecurity tools, and developer utilities across GitHub.
Do I need a GitHub account?
No GitHub account is required to search or browse. A RepoFinder account is only needed if you want to save repositories or view your history.
How is RepoFinder different from searching GitHub directly?
RepoFinder wraps GitHub search in a faster, distraction-free interface with curated categories, saved lists, and filters designed around how developers actually evaluate libraries and frameworks.
