## What it is
EtherCalc is a web-based spreadsheet server for real-time multi-user collaborative editing, a TypeScript rewrite of the original SocialCalc-based EtherCalc. It runs on the Cloudflare fullstack (Hono, Workers, Durable Objects, D1, KV, R2) and can also self-host via Docker or a local CLI without a Cloudflare account.

## Use cases
- collaboratively edit a spreadsheet with teammates by sharing a URL
- embed a live multi-user spreadsheet into a Drupal site
- self-host a collaborative spreadsheet server on my own infrastructure
- run a realtime spreadsheet on Cloudflare Workers
- share a spreadsheet link for simultaneous editing without accounts
- integrate spreadsheet editing into a web app via a REST API

## When to choose
- you need lightweight, anonymous, real-time collaborative spreadsheets with just a shared URL
- you want a self-hostable spreadsheet server with Docker or Cloudflare Workers deployment
- you need a REST API to programmatically read and write spreadsheet cells
- you want a free, open-source alternative to hosted collaborative sheets

## When to avoid
- you need heavy spreadsheet features like formulas, pivot tables, or charts comparable to Excel or Google Sheets
- you require strong access control or authentication — rooms are anonymous read/write to anyone with the URL
- you plan to expose it to the public internet without adding your own TLS-terminating reverse proxy and rate limiting
- you need offline desktop spreadsheet functionality
