Serverless edition

crashcart-serverless is CrashCart on Cloudflare Workers. Same SDK setup, same viewer, same export format.

When to use it

Nothing to run, free for small apps, $5/month for most others. See Which edition? for the comparison with the Go edition and the limits worth knowing.

Deploy

git clone https://github.com/crashcartapp/crashcart-serverless
cd crashcart-serverless
npm install
npx wrangler login
npx wrangler d1 create crashcart          # paste the database_id into wrangler.jsonc
npx wrangler r2 bucket create crashcart-blobs
npm run db:migrate:remote
npx wrangler secret put API_KEYS
npx wrangler secret put VIEWER_PASSWORD   # optional
npx wrangler deploy

Open the Worker URL, create a project, copy its DSN. The same optional settings apply: PUBLIC_URL, RETENTION_DAYS, CORS_ORIGIN, PII_REDACT, CUSTOM_TAGS, TELEGRAM_BOT_TOKEN.
