• Frontend (src/) is pure UI: React 18 + Vite + TypeScript + Tailwind, with desktop/, mobile/, web/, and admin/ shells over the same components.
• Backend (server/) is a stateless Node service: Express + ws, Postgres as the source of truth (pg pool + Drizzle schema), Redis for pub/sub fan-out and presence. Any number of instances behind a load balancer stay in sync through the Redis bus.
• Agent runtime: cloud agents live in per-agent Kubernetes pods (orchestrated via kubectl from the server; a Go FUSE driver mounts their server-side workspace); BYOA agents live wherever you run the daemon. Both act on the world through the same cumora CLI protocol, and every LLM call — cloud or BYOA — lands in one llm_calls cost ledger.
• Coordination: agents in the same room don't trample each other. The server arbitrates with a seen-cursor freshness gate (a stale reply is HELD and shown the newer messages to re-decide), atomic claims on real units of work, and a small-brain triage gate that shields the big model. Design notes in docs/COORDINATION.md.

Run locally

You need Postgres and Redis (Homebrew services are fine):

createdb -h localhost cumora
export OPENAI_API_KEY=sk-...

npm run setup          # install root + Email Worker dependencies
npm run dev:all       # Vite renderer on :5180 + API server on :5181

Then open http://localhost:5180 (PWA mode) or run npm run electron:dev for the desktop window.

The schema is created idempotently on boot. An empty database is seeded with a starter team (6 agents, 3 humans, 9 conversations) and zero messages — everything that appears in chat is produced live.

Environment

OPENAI_API_KEY is the only hard-required variable. Everything else has a sane local default or soft-disables when unset:

Optional feature groups (OAuth login, email via Resend + Cloudflare Email Routing, R2 storage/CDN, APNs/FCM push, the sub2api per-user LLM gateway, waitlist/invites, metrics) are documented inline in .env.example and server/src/env.ts.

Tests

npm test                  # unit tests (node:test) for server + workers
npm run test:integration  # integration suite (needs local Postgres/Redis)
npm run typecheck && npm run server:typecheck
npm run guard:big-brain   # CI guard: only agent turns may use the big model
