User guide
EtherCalc is the spreadsheet equivalent of a wiki page: no logins, no editing locks. Everyone with the link can edit the same sheet at the same time.
This guide replaces the old GitHub wiki, which is no longer maintained. For API and deployment topics, see Self-hosting and API.md in the repository.
Use cases
Section titled “Use cases”When might you reach for EtherCalc?
- Scheduling — participants update their own availability; everyone sees the latest headcount per slot without e-mail ping-pong.
- Carpooling — who rides with whom, how many seats remain.
- Peer grading — students score each other’s work in a shared grid.
- Live run-of-show — a producer updates a roadmap sheet; studio staff follow along with no refresh button.
