Score: 6.5/10 (Innovation: 7, Technical: 7, Documentation: 6, Utility: 6)

Foretype is a Rust tool that provides optimistic local echo for SSH and other remote shells, making typing feel instant even on high-latency connections. It installs as a login shell wrapper, runs the real shell in a pty, and predicts keystrokes while reconciling with the server's actual echo. The approach is clever and technically non-trivial, addressing a real pain point for remote developers.

Target audience: backend developers, devops engineers, remote developers
