Open Signal Foundation supports open-source tools for censorship-resistant communication, offline news delivery, emergency alerts, and safe internet access for high-risk communities.
Governments and crises can shut down networks, filter content, and spread misinformation. Communities lose access to verified news, emergency alerts, and essential services — often when they need them most.
Open Signal Foundation exists to build resilient, open-source tools that help people access verified information even when normal connectivity fails.
We research, build, and maintain censorship-resistant communication tools designed for high-risk environments — with safety and transparency at the center.
Build open-source tools that help people access verified information when the internet is blocked, unsafe, or unreliable.
