Jelly is an experimental terminal forum for developers and friends. Everything happens over SSH. No web UI, no javascript, just text.

Practice Linux commands, write bash scripts, and learn system administration — free, in your browser. No install required. Running since 2011 with 500k users.

I gave a talk at the 2025 Tracing Summit last month titled “Perfetto: The Swiss Army Knife of Linux Client/Embedded Tracing”.

Does like MacOS Preview, extracts text from images.
