Frequently Asked Questions
Everything you need to know about billing, upgrades, and team management.
Can I switch plans mid-cycle?
Yes. Upgrades take effect immediately with prorated billing. Downgrades apply at the start of your next billing cycle, so you never lose access before your paid period ends.
Is the Free tier really unlimited?
The Free tier offers unlimited real-time testing sessions. The only limit is the 10-pattern save cap to prevent abuse. You can test complex regexes on datasets up to 5MB without restriction.
How does the Enterprise API work?
Enterprise customers receive a dedicated API key and webhook endpoints. You can programmatically validate regex patterns, run performance benchmarks, and sync saved patterns directly into your CI/CD pipelines.
Do you offer discounts for open source or education?
Absolutely. Verified open-source maintainers and accredited students receive 100% off Pro. University departments and non-profits qualify for 40% off Enterprise. Email billing@regexlab.io with proof.
