1 month ago 10

The complete development platform for AT Protocol applications. Deploy schemas, query indexed data, authenticate users.

Skip the infrastructure. Focus on your app logic. Everything you need to ship production AppViews with type-safe APIs and automatic indexing.

Auto-Indexing Engine

Real-time data sync from the AT Protocol network.

Automatically discover and index records matching your lexicons. Connected to the firehose to keep your data fresh.

Type-Safe APIs

Generated clients with collection methods.

From lexicon to production code in seconds. Get fully-typed getRecords(), createRecord(), updateRecord(), and deleteRecord() methods with filtering, sorting, and pagination. Complete with project templates for popular frameworks and CLI tools to scaffold your AppView. Complex infrastructure made simple.

Schema Management

Define once, query everywhere.

Configure lexicons that instantly become queryable collections. Built-in validation ensures your schemas work correctly from day one. Deploy and start querying immediately.

User Authentication

OAuth flows that just work.

Production-ready authentication with OAuth 2.0 PKCE for web apps and Device Code Auth for CLI tools. Automatic token management, refresh handling, and secure session storage. Focus on features, not auth infrastructure.

Production-Ready Operations

Everything you need to monitor, manage, and scale your AppView in production.

Jetstream Logs

Real-time connection monitoring and detailed event logs for debugging and observability.

Data Backfill

Historical data synchronization and migration tools to populate your AppView from scratch.

Waitlist Management

User onboarding and access control workflows for managing early access and beta testing.

Record Explorer

Visual query interface with advanced filtering, search, and data exploration capabilities.

Built for Collaboration

Share lexicons, discover AppViews, and learn from the community timeline.

Community Timeline

See what other developers are building. Get inspired by new lexicons and AppView implementations.

Lexicon Discovery

Browse and fork community lexicons. Build on proven schemas instead of starting from scratch.
