Backend not ready? Paste your JSON and get a working REST API your frontend can call today.

  • 1 project with up to 4 resources and 100 records per resource
  • Create resources by pasting JSON (arrays and objects are inferred), from a field table, or by importing an OpenAPI 3 JSON or YAML file
  • Realistic seed data picked from field names and formats (email, name, avatar, price, createdAt, uuid and 50 more), reproducible from a fixed seed
