FAQ

Can I use Community tier in production?

Yes. The Community tier is fully functional and suitable for production use. There are no artificial limitations or "nagware".

What happens when my license expires?

  • Your application continues to work
  • You retain access to features available at your last validated tier
  • After 7 days offline, validation falls back to Community tier
  • No data loss or service interruption

Can I upgrade or downgrade?

Yes. Contact our sales team to change your tier. Upgrades are prorated, downgrades take effect at the next billing cycle.

Is there a trial for Professional/Enterprise?

A 14-day trial is coming soon. Contact us to be notified when it's available.

Do you offer discounts for startups?

Yes. Early-stage startups (under £1M funding) may qualify for 50% off Professional for the first year. Contact us with your company details.

How does per-seat pricing work for Enterprise?

Enterprise licenses are based on the number of developers who use OxideShield™ in their work. Each developer who writes code using OxideShield™ or configures guards requires a seat.
