Summary

On July 27, 2026, Cloudflare open-sourced pvcli, a curl-like command-line tool built to simplify testing of complex privacy protocols such as Oblivious HTTP (OHTTP). It gives developers a scriptable client for exercising privacy-preserving request flows from the terminal.

What changed

Cloudflare released pvcli as open source. Modeled on curl, it lets developers issue and inspect requests over privacy protocols like OHTTP without building bespoke tooling, lowering the bar to test and adopt these flows.

Why it matters

Privacy protocols like OHTTP are notoriously hard to test, which slows adoption; a familiar curl-style client makes them approachable and auditable. Open-sourcing it seeds ecosystem tooling around Cloudflare's privacy stack and nudges these protocols toward routine developer use.
