Every developer needs realistic test data at some point. But the options are limited: Mockaroo charges $49/month for features like SQL export and Excel, Faker.js requires a backend, and random generators create isolated fields with no correlations between them. Fake Database is a free, browser-based tool that solves this. It generates realistic fake data with 120+ fields across 19 categories, 15 pre-built templates, and 7 export formats. What makes it different: • Cross-field correlations — gender determines name, age determines salary, car brand determines model. Data is internally consistent, not random. • 7 export formats — CSV, Excel (.xlsx), JSON, SQL (CREATE TABLE + INSERT), XML, YAML, and interactive table view. Most competitors charge $49/month for SQL + Excel. • Custom columns — add unlimited fields with SQL-like types (INT, VARCHAR, DATE, UUID, etc.) • Null & error injection — configurable rates for edge-case testing • US + Brazilian data — locale-aware formatting for CPF/CNPJ, SSN/EIN, addresses, phones, dates • 100% client-side — no server, no signup, no data sent anywhere Built with React, TypeScript, and Vite. Open source.
