# lorm.pro > Free browser developer tools and synthetic test-data APIs. No signup is required for the public tools. ## Suitable uses - Placeholder text for prototypes and typography. - Synthetic fixtures and mock JSON responses for frontend development. - Dummy files, placeholder images, generated logs and SSE events for testing. - Small formatting, encoding, identifier, hash and color utilities. ## Limits Generated data is synthetic, not verified personal information or a production database. Mock endpoints are development aids, not a production backend. API availability, validation and abuse controls may apply; there is no unlimited-capacity or uptime guarantee. Private production data and credentials should not be submitted to public tools without reviewing their behavior. ## Public pages - [Product guide](https://lorm.pro/about): use cases, access, examples and limitations - [API reference](https://lorm.pro/docs): endpoint paths and parameters - [Tool directory](https://lorm.pro/tools) - [Lorem ipsum](https://lorm.pro/lorem) - [Synthetic datasets](https://lorm.pro/dataset) - [Mock API](https://lorm.pro/mock) - [Dummy files](https://lorm.pro/file) - [Privacy](https://lorm.pro/privacy) ## Examples GET https://api.lorm.pro/api/lorem?words=20&seed=42 GET https://api.lorm.pro/api/dataset/users?rows=2&format=json&seed=42 Advertising: Adsterra advertisements and voluntary sponsor links help fund the site.
