Introduction & Architecture

Data sovereignty philosophy and native async Rust performance behind CAPost.

Why CAPost?

Leading API development clients have devolved into bloated cloud platforms requiring mandatory logins and storing confidential credentials on third-party servers.

CAPost restores data sovereignty to engineers:

Git-First Open Format: Pure YAML OpenCollection format with zero cloud locks.
Zero-Knowledge Security: Secrets encrypted locally with SQLCipher 4 and Argon2id.
Extreme Rust Speed: Cold-start under 300ms and memory footprint under 65MB.
