DDL to Data – Generate realistic test data from SQL schemas
I built DDL to Data after repeatedly pushing back on "just use production data and mask it" requests. Teams needed populated databases for testing, but pulling prod meant security reviews, PII scrubbing, and DevOps tickets. Hand-written seed scripts were the alternative slow, fragile, and out of sync the moment schemas changed. Paste your CREATE TABLE statements, get realistic test data back. It parses your schema, preserves foreign key relationships, and generates data that looks real, emails look like emails, timestamps are reasonable, uniqueness constraints are honored. No setup, no…
In plain words
DDL to Data generates realistic test data directly from SQL schemas without requiring production data or manual setup. Users paste CREATE TABLE statements and receive populated databases with valid foreign key relationships, realistic formatting for emails and timestamps, and honored uniqueness constraints. It works with PostgreSQL and MySQL, automatically parsing schemas and updating when they change, eliminating the need for hand-written seed scripts or complex security reviews. The tool is designed for development teams and QA engineers who need functional test databases quickly.

No setup, no config. Works with PostgreSQL and MySQL. https://ddltodata.com Would love feedback from anyone who deals with test data or staging environments. What's missing?

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
