subway - ABANDONED - A web based IRC client

•    Javascript

Subway is not currently functional and not under active development. While the plan is to finish this project some point in the future, currently the maintainer strongly suggests taking a look at The Lounge. Subway is a web-based IRC client with a multi-user backend and a JavaScript-heavy UI. Frontend/backend communication is done with websockets (or best available fallback where not available). The backend supports connection persistence and optional logging when the browser disconnects.

CloudBot is currently unmaintained. The project possibly usable, but there are currently no developers building new features or fixing bugs.

If you already have a running CloudBot instance you will probably need to start over from scratch.
