Both protect your files with zero-knowledge encryption.
But modern cryptography has evolved — here's exactly where 1Cryptor leads.
Every difference is verifiable and matters in real-world use.

Technical choices have real consequences for security and daily use.
Any modification to your encrypted file is instantly detected. Cryptomator requires two separate primitives (encryption + HMAC) that must be perfectly combined. Fewer moving parts = smaller attack surface.
The 2015 Password Hashing Competition winner. Uses 128 MB of memory per password attempt — making GPU brute-force attacks extremely expensive compared to scrypt.
Cryptomator is genuinely excellent open-source software. It proved that zero-knowledge encryption can be practical. We built 1Cryptor because we believe the next evolution — Argon2id, GCM, Rust, and native iOS — is worth building. 1Cryptor will become fully open source soon.
1Cryptor is paid with a generous free starter vault. Open source coming soon.
