Auto-Generated REST API
The moment you define a schema, Baasix creates a complete REST API for it. Full CRUD operations, advanced filtering, pagination, sorting, and nested relations — all without writing a single endpoint.
Your Backend, Instantly Ready
Traditional API development means weeks of writing endpoints, handling edge cases, and debugging query logic. Baasix eliminates all of that.
Every collection in Baasix automatically gets a full REST API with Create, Read, Update, and Delete operations. But that's just the beginning. You also get advanced filtering with over 50 operators, flexible sorting, pagination, field selection, and the ability to include nested relationships in a single request.
- Instant CRUD endpoints for every collection you create
- Over 50 filter operators: eq, gt, lt, contains, between, regex, and more
- Flexible sorting with multi-field support and direction control
- Cursor-based and offset pagination out of the box
- Select specific fields to reduce payload size
- Include nested relations in responses with dot notation
- Aggregation queries: count, sum, avg, min, max with grouping

✓ With Baasix
- Full API ready the moment you create a collection
- Complex filters via URL params — no code needed
- Automatic pagination with metadata
- Relations included with simple parameter
- Type-safe responses with generated TypeScript
✗ Traditional Approach
- Write endpoint handlers for every operation
- Build custom query parsers for each filter type
- Implement pagination logic and calculate totals
- Write complex SQL JOINs for every relation
- Manually keep API docs and types in sync
API Capabilities That Scale With You
50+ Filter Operators
From simple equality to regex matching, array operations, JSONB queries, and geospatial filters. Query your data any way you need.
Advanced Sorting
Sort by multiple fields, control direction, and even sort by nested relation fields. Perfect for complex data displays.
Nested Relations
Fetch related data in a single request. Include nested objects up to multiple levels deep with simple dot notation.
Full-Text Search
Built-in full-text search across multiple fields. PostgreSQL-powered search that handles multiple languages.
Aggregation Queries
Run count, sum, average, min, max queries with grouping. Build dashboards and reports without custom endpoints.
Bulk Operations
Create, update, or delete multiple records in a single request. Perfect for imports, batch updates, and data migrations.
Advanced JSON Filters
MongoDB-style querying with over 50 operators for ultimate flexibility.
Baasix supports a powerful JSON-based filtering system that feels familiar to MongoDB users but works with PostgreSQL. Nest conditions with AND/OR operators, traverse relations, and build complex queries — all through a clean, intuitive API.
- _and and _or logical operators for complex conditions
- Nested relation filtering with dot notation (e.g., user.role.name)
- Array operators: contains, containsAny, overlap
- JSONB operators for querying JSON fields
- Comparison operators: eq, neq, gt, gte, lt, lte, between
- String operators: contains, startsWith, endsWith, iLike, regex
- Null and empty checks: isNull, isEmpty, isNotNull
- Deep filtering across multiple relation levels
Built for Real-World Applications

E-commerce Platforms
Product catalogs with complex filtering (price ranges, categories, attributes), inventory management, and order processing APIs.
Content Platforms
Build blogs, documentation sites, or media platforms. Full-text search, category filtering, and nested comments all work automatically.
Common Questions
Can I customize the API endpoints?
Yes! You can add custom endpoints using the extensions system. Custom hooks let you modify requests/responses, add validation, or implement custom business logic while keeping the auto-generated base.
How does filtering work with relations?
You can filter by related fields using dot notation. For example, filter products by category name, or orders by customer email. The API handles the joins automatically.
How do I include related data in responses?
Use the fields parameter with dot notation: ?fields=*,category.*,author.name. This includes the full category object and just the author name in your response.
What about API versioning?
Baasix supports API versioning through URL prefixes. You can maintain multiple versions of your API for backward compatibility during transitions.
