Frequently Asked Questions

What counts as a Monthly Active User (MAU)?

An MAU is a unique user who performs at least one verified action in a calendar month. We count unique email addresses or DIDs.

What happens if I exceed my tier limit?

You'll be automatically upgraded to the next tier and billed accordingly. For example, if you have 1,500 users on the Free tier, you'll automatically upgrade to Starter ($5/month).

Can I cancel anytime?

Yes! You can downgrade or cancel anytime from your dashboard. No long-term contracts or cancellation fees.

Do you offer discounts for nonprofits or education?

Yes! Contact [email protected] with proof of nonprofit status or .edu email for special pricing.

How does billing work?

We bill monthly via Stripe. Your first month is prorated. You can view detailed usage and invoices in your dashboard.

What payment methods do you accept?

We accept all major credit cards (Visa, Mastercard, Amex, Discover) through Stripe. Enterprise customers can pay via invoice/wire transfer.

Is there a free trial?

The Free tier is permanently free for up to 1,000 MAU. There's no credit card required to get started!

How is Lemma faster than Auth0?

Lemma uses client-side verification (WebAssembly) which runs in the user's browser at 0.36µs. Auth0 requires API calls to their servers (200-500ms). That's up to 1,000,000x faster!
