Highly customizable open-source online editor providing collaborative editing in real time.
A long-running, widely deployed collaborative editor that is great for throwing up a shared pad fast, with a huge plugin ecosystem behind it. The tag says it plainly: documents are unencrypted, so whoever runs the server can read everything, which means trust depends entirely on who hosts it. Run your own instance for casual team notes and brainstorming; do not put anything sensitive on a public pad.
