The Frontend SDK is built on contracts, not dependencies. Use 23blocks services or bring your own backend — as long as it speaks the same language, it just works.
Every endpoint follows the JSON:API specification. Standardized request/response formats mean predictable, reliable integrations.
Using 23blocks Auth today but want to build your own? Implement the contract, point the SDK at your server, done. Zero frontend changes.
The contract is open. The SDK is open. Your architecture remains yours — we're just making it easier to build.
// Use 23blocks services const client = new BlocksClient({ baseUrl: 'https://api.23blocks.com' }); // OR use your own backend const client = new BlocksClient({ baseUrl: 'https://your-api.com' }); // Same SDK. Same code. Same types. // Your backend just needs to implement // the 23blocks contract (JSON:API format)
→ The contract defines endpoints, models, and response formats. Implement it in Rails, Node, Go, or any language you prefer.
