Credits and inspiration

Celly is inspired by remorses/kimaki (MIT). Celly reimplements Kimaki’s core idea — channels as projects, threads as sessions — and runs each project in an sbx sandbox instead of a local process. Built on Docker Sandboxes (sbx) and OpenCode. Celly’s own code is MIT; see LICENSE.
