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
