About Etherpad

Etherpad is a web-based collaborative editor where dozens of people can type simultaneously, with per-author colors, chat and version history. Ideal for teams that want Google-Docs-style collaboration on their own server.

Etherpad is completely free and open source (Apache-2.0) — no trials, no subscriptions, no locked features. Always download from the official website to avoid bundled malware.
