One Less Slave
Browse Projects Submit a Project

Every contribution is one step closer.

This catalog grows with its community. Whether you build software, write documentation, or work on the front lines, there's a way for you to help equip the world to end modern slavery.

Submit a project

Maintain or know an open-source tool that fights trafficking or online exploitation? Propose it for the catalog.

Improve a guide

Make a setup guide clearer, fix a broken link, or translate documentation so more people can deploy these tools.

Deploy & spread the word

Put these tools to work in your organization, school, or home — and tell others who need them.

How to submit a project

We keep the catalog open and transparent. The fastest way to propose a tool is to email us with the details. Good candidates are:

  • Open source with a clear license and a public repository.
  • Actively maintained with recent commits and responsive maintainers.
  • Relevant to preventing online exploitation or fighting human trafficking.
  • Documented, with installation instructions someone can realistically follow.

Tell us the repository URL, which category it fits, a one-line summary, and how it helps. Our maintainers review every submission for relevance, maturity, and safety before it's added.

Found a tool that doesn't belong?

We take safety seriously. If a listed project becomes unmaintained, changes its license, or could be misused to cause harm, please email us so we can review and remove it.

This is a catalog of tools, not an emergency service. If you or someone you know needs help now, call the National Human Trafficking Hotline (1-888-373-7888) or your local emergency services.
