Circumvention tech

Circumvention tech helps people evade censorship that blocks access to information and communication.

Engineering Lab at Open Tech Fund

The lab focuses on supporting the implementation and inclusion of established technologies into existing applications, organizations, and communities that are advancing Internet freedom, supporting the initial/bootstrap operating and infrastructure costs associated with getting deployments online, and, finally, conducting one-off assessments of existing apps or websites for recommended privacy, security, or anti-censorship improvements. All of this work will be conducted either by service partners or applicants themselves—with triage and oversight by an OTF.
