What is CATerm?
CATerm is a modern desktop SSH and SFTP client built from scratch in Rust. Designed specifically for cloud architects, sysadmins, and DevOps engineers who demand zero input lag, minimal memory footprint (< 30MB idle), and military-grade Zero-Knowledge encryption.
Architecture Highlights:
- Uncompromised Native Performance: 100% pure Rust backend with no garbage collector overhead. Remote PTY sessions run through dedicated
ssh2channels on isolated OS threads. - Zero-Knowledge Encryption: All server credentials, SSH private keys, and session configs are encrypted locally with Argon2id and SQLCipher (AES-256-GCM). Encryption keys never leave your machine.
- Integrated Dual-Pane SFTP: WinSCP-grade file manager featuring real-time MD5/SHA256 checksum verification, remote in-place editor, and server-side tar/zip compression.
- Zero Telemetry: No analytics, tracking, or remote phone-home mechanisms. Your infrastructure data remains strictly private.
