Generate realistic test data in your browser.
Pick the columns, hit Generate, copy the result. Names that look like real names, IBANs that pass checksum, IMEIs that pass Luhn, everything you need to fill a test fixture in seconds.
Create your data
Every column type a tester actually needs.
Localised names and addresses, valid identifiers, dates that respect your range. Add a custom regex if you need something we don't have.
Move from browser to platform.
The free tool covers ad-hoc fixtures. The full DataMaker platform handles the rest of the job, templates, connections, scenarios, an AI agent, SAP, and a desktop app that runs it all locally.
Save your schema
Turn this in-browser table into a named template you can run again, share with your team, or call from an API.
Push directly to your DB
Connect Postgres, MySQL, Mongo, MSSQL, Oracle, or DB2 and seed thousands of records without copy-paste.
Talk to SAP OData
Auto-CSRF, $metadata discovery, V2/V4, generate, fetch, or POST to any SAP OData endpoint.
Just describe the data
Tell DataMaker's in-app agent what you need in plain English, it designs the template, generates the rows, and seeds your target for you.
Drive it from Claude or Cursor
DataMaker's MCP server gives any AI coding agent a full toolset to generate and seed data without leaving the editor.
Run it on your own machine
Install the desktop app and run the whole platform locally, generate and seed against internal systems while your data never leaves your network.
