About Open Source Tools

Open Source Tools is a free, curated directory of open source software. We believe in tools you can own, run, and audit yourself - not rent.

We gather open source apps from across the web, organize them into clear categories, and map them to the proprietary products they can replace. For each tool we surface real signals - the license, the languages, and live GitHub activity - so you can judge what is genuinely maintained before you commit.

Doing this at scale is rare: only a handful of projects anywhere catalog open source software this broadly. That breadth - hundreds of categories and alternatives gathered in one place and kept current - is the value we set out to provide.

We are not a tracker. We do not collect personal data, profile you, or monitor what you do here. The site is supported solely by Google AdSense advertising - there is nothing else running in the background.

Whether you want a self-hosted analytics tool, an open source CRM, or a privacy-respecting password manager, Open Source Tools helps you find software that matches your values.
