We empower communities to create peace through technology

Who we are

We are a US 501(c)(3) non-profit organization based in San Francisco and Barcelona. We are passionate about using technology for good. JustPeace Labs offers technical assistance to help organizations create software for peacebuilding, human rights and development work.

We also promote ethical and conflict-sensitive approaches to using technology in complex settings. Contact us to discuss how we can work together.

Our Approach

Technical Assistance
Creating custom, targeted software tools using innovative technologies.

Ethics and Security
Promoting ethical and secure approaches to tech in complex settings.

Providing research and advice to peacebuilders, policymakers and corporations.

HateTracker App

Hatred and intolerance threaten and divide our communities. Governments and civil society alike struggle to respond to and track increased incidents of hate crimes.

Data is necessary to understand, strategize, and collectively mobilize against hate. With data, we can combat these incidents and facilitate trust and collaboration between the community and law enforcement.

HateTracker is a secure web-based app to report hate incidents people experience or witness.
