# Fossy

> Fossy is the world's only directory dedicated to the greatest free and open-source software. Every project is hand-picked and ranked by live GitHub signal (stars, forks, contributor activity). Fossy surfaces the best of the open-source community - from infrastructure and developer tools to productivity apps and AI frameworks - with rich metadata: primary language, topics, license, platforms, contributors, and more.

## Open-Source Alternatives

Each popular proprietary tool that has a FOSS alternative on Fossy gets a dedicated comparison page at `https://fossy.dev/alternative-to/{slug}` (e.g. `https://fossy.dev/alternative-to/figma`). These pages include:
- All open-source projects that replace the same proprietary tool
- An interactive side-by-side comparison matrix across those projects
- Feature comparison bullets ("Why X beats Y")
- Article-style content with social post highlights
- Search, sort (by stars, name, or date), and collapsible project cards
- Links back to each project's detail page

Project detail pages also have an "Alternative To" tab linking to the full comparison page when applicable.

## Project Detail Pages

Each project has an internal detail page at `https://fossy.dev/{github_owner}/{github_repo}` (e.g. `https://fossy.dev/n8n-io/n8n`). These pages include:
- Full description and tagline
- GitHub stars, forks, last commit date
- Primary language and language breakdown (percentage bar)

- A "Videos" tab with embedded YouTube walkthroughs, reviews, and shorts of the project (when available), with the full video description below long-form players
- Links to website, source code, and live demo when available

## Contributor Detail Pages

Each contributor has an internal profile at `https://fossy.dev/contributors/{github_login}` (e.g. `https://fossy.dev/contributors/torvalds`). These pages include:
- GitHub avatar and login
