WezTerm
FreeA cross-platform terminal configured in Lua, with the most complete multiplexing
An MIT-licensed cross-platform terminal with 28,408 stars, written in Rust. Configuration is Lua, which makes it highly flexible, and multiplexing is built in so you get session detach and remote multiplexing without tmux. Note its licence file is named LICENSE.md, which GitHub sometimes fails to classify — it is standard MIT.
Why we picked it
WezTerm's strength is multiplexing: session detach and remote multiplexing are built in, so you do not need tmux alongside it. 28,408 stars, written in Rust, across all three platforms.
Configuration is Lua, so you can write logic rather than just fill in key-value pairs — there is a lot of room to tinker.
One common misconception worth clearing up: GitHub sometimes fails to show its licence because the file is named LICENSE.md rather than LICENSE. Open it and it is standard MIT.
