FlareMail is open source, and its backend is a single Cloudflare Worker backed by D1 (metadata) and R2 (message bodies). If you'd rather run it on your own Cloudflare account, the repo includes a one-shot, idempotent provisioning script.

One-shot setup

First authenticate Wrangler (this opens a browser), then run the setup script from the repo root:

npx wrangler login
node scripts/setup-cloudflare.mjs

The script verifies auth, creates (or reuses) the flaremail D1 database and flaremail-mail R2 bucket, applies migrations to the remote database, sets an APP_SESSION_SECRET, and deploys the Worker. Re-running it is safe — it reuses existing resources.

Prefer to do it by hand?

wrangler d1 create flaremail          # paste database_id into wrangler.toml
wrangler r2 bucket create flaremail-mail
wrangler secret put APP_SESSION_SECRET
npm run migrate:remote
npm run deploy:api

When it's deployed, put your Worker's URL into FlareMail under Settings → Connection, then sign up or sign in from the app. For inbound mail, add the Email Routing rule pointing at your Worker.
