Persistent records
PostgreSQL-backed JSON records survive reloads and behave like a small production API.
Persistent while you build. Disposable when the work is done.
Backlet gives prototypes, tests, and demos a persistent REST API in minutes—without writing or deploying backend code.

}Backlet gives you the parts of a real backend that frontend work depends on: structured data, stable routes, persistence, and observable requests.
Open the API reference (opens in a new tab)Generated collection endpoint
/p/storefront/products
Create ordered, typed fields manually or import a CSV. Backlet validates every record against the Resource.
Create, query, update, and delete persistent records with the HTTP client your frontend already uses.
Trace requests, add deterministic custom responses, or protect the API with scoped keys on Solo.

Create a backendRecords persist for the life of the Project. Expiration stops API traffic first, then keeps the Project recoverable before permanent deletion.
Compare Free and SoloActive
Free Projects run for 7 days; Solo Projects run for 60. Records, schemas, endpoints, and request history stay available.
Expired
API traffic returns 410 Gone, while your workspace and data remain recoverable for 7 more days.
Deletion
After the recovery deadline, Backlet permanently deletes the Project and its data. Solo owners can reactivate; Free owners can upgrade to recover it first.
Use familiar HTTP tools without giving up the persistence and observability a serious integration needs.
PostgreSQL-backed JSON records survive reloads and behave like a small production API.
Custom endpoints take priority over generated CRUD, with request-driven rules and fixed delays.
See method, path, status, duration, and timestamp for every completed Data Plane request.
Start open while prototyping, then require scoped API keys when a demo needs privacy.
Create up to three free Projects, import your data, and connect with a URL you can use immediately.
