Teamora

A real-time workspace for documents, sheets, slides, whiteboards, tasks, chat and meetings, on a cluster I built.

5services, plus workers for email, jobs, indexing and speech

273automated tests, and 10 full browser flows

The hard parts

"Saved" has to mean saved

Problem: In a shared editor, an edit can be lost between your screen and the server without anyone noticing.
What I did: "Saved" appears only once the server has committed your edit. Until then the draft waits in the browser, and it survives reloads and dropped connections.

One place decides who can see what

Problem: When every route checks permissions its own way, they drift apart and something leaks.
What I did: A single permission service answers for everyone. If it cannot answer in time, access is denied, and people outside a workspace cannot tell it exists.

An assistant that cannot bluff

Problem: An AI that invents answers or acts alone is dangerous inside a team's documents.
What I did: It answers only from quotes it can cite, and says "not known" otherwise. Actions pause for your approval, which re-checks your permission. A 55-case test set guards it.

A "database outage" with a healthy database

Problem: Creating an assigned task returned "service unavailable", yet every service and the database were healthy.
What I did: The ORM was trying to save a half-built task during a lookup. I reproduced it in a real-database test and fixed the order: build the task first, save it last.

Also in it

Four editors: documents, spreadsheets, presentations and whiteboards
Import and export for DOCX, PPTX, XLSX, CSV, Markdown and PDF
Tasks, calendar, chat, reminders and notifications
Meetings with live captions, searchable transcripts and cited summaries
Google sign-in with rotating, revocable sessions
An MCP server, so coding agents can use the same tools
Used by people besides me to co-edit documents
Releases through GitHub Actions with no stored AWS keys
