We Are Open-Sourcing Our Privacy Proxy CLI
Cloudflare, Monday, July 27th, 2026
Cloudflare releases pvcli, a curl-like tool for testing privacy protocols such as OHTTP.
Cloudflare open-sourced pvcli, a curl-like command line tool built to simplify testing of complex privacy protocols including Oblivious HTTP.
Protocols such as OHTTP involve multiple relays and encapsulation layers that make ad hoc testing with standard tools painful.
The tool gives developers a familiar interface for issuing requests through those layers and inspecting what happens at each hop.
Releasing it publicly is intended to lower the barrier for others implementing privacy-preserving protocols. The post covers usage and the protocols currently supported.
