How it works
- Buy Structura Pro on Gumroad for $19. You receive a license key by email.
- Paste the key above and click Activate.
- Pro features unlock in this browser immediately. Activate again on your other browsers or computers with the same key.
- Structura re-checks the license about once a week in the background. Nothing else is sent.
Why Pro exists, and what it does not change
Structura runs entirely in your browser, which keeps your data private and keeps the tools free to run. Pro pays for continued development of the tools you rely on. It does not add accounts, tracking, or uploads: the only thing that leaves your browser is the license key, which is checked with Gumroad when you activate.
What you get
- Higher limits for real exports: 25 MB and 100,000 rows instead of 5 MB and 20,000
- Batch comparison: compare a folder of monthly exports against the previous month in one run
- Unlimited saved validation rules for recurring imports
- Larger test datasets for load testing and demos
