SaaS Starter

Identity, authentication, and account management for your users.

Charge customers via one-time purchases, subscriptions, or usage-based billing.

Alert users about events relevant to them across multiple delivery channels.

Control who can do what inside your product — from simple role toggles to fine-grained, resource-scoped authorization.

Serve multiple customers / organizations from one product while keeping their data, config, and users isolated.

Send reliable, deliverable emails triggered by product events — verification, password reset, receipts, invitations, and system alerts.

An immutable record of who did what, when, and from where — for compliance, security investigation, and customer-facing transparency.

Run work asynchronously outside the request path — emails, exports, integrations, scheduled tasks, and anything slow enough to break a web request.

Prevent abuse, contain bursts, and enforce fair use across authenticated APIs, public endpoints, and expensive operations.

Guide new users from sign-up to their first meaningful outcome — the moments that determine whether they ever come back.
