Shopify

Identity, authentication, and account management for your users.

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

Let users find content quickly — from simple filters to full-text and semantic search.

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

Upload, store, and serve user-generated files — documents, images, and media.

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

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.
