Identity, authentication, and account management for your users.

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

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

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

Real-time text communication between users — channels, DMs, and threads.

Understand how users interact with your product through event tracking, funnels, and retention analysis.

Internal tooling for operations, support, and moderation teams to manage users, content, and configuration.

Show users a chronological or ranked stream of relevant events — follows, posts, mentions, workspace activity — with real scaling considerations.

Let users discuss objects in your product — posts, documents, PRs, designs — with threading, mentions, and moderation.

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.
