What do these mean?
Social login
Let people sign in with an account they already have, such as Google or GitHub.
Passwordless sign-in
Sign in with a link or a one-time code sent by email, with no password to remember.
Multi-factor authentication
A second step at sign-in, such as a code from an authenticator app, so a stolen password is not enough.
Custom domain
The sign-in pages and emails live on your own address, like login.yourapp.com, not the vendor's.
Passkeys
Sign in with a fingerprint, face or device PIN instead of a password. Harder to phish.
Remove vendor branding
Hide the "secured by" badge on the prebuilt sign-in screens.
User data export
Download all your users' records so you can move to another provider.
Organizations (teams)
Group users into companies or teams, each with its own members and settings. Needed for B2B apps.
Roles and permissions
Decide what each user may do, for example admin versus member.
Enterprise single sign-on (SAML)
Let a customer's staff sign in with their company login (Okta, Microsoft Entra and similar). Big customers often require this.
Automatic user provisioning (SCIM)
A customer's IT team adds and removes your app's users from their own directory.
Audit logs
A record of who signed in and what changed, for security reviews and compliance.
Machine-to-machine tokens
Credentials for one backend service to call another, with no human signing in.
Uptime guarantee (SLA)
A written promise of availability, such as 99.99%, usually with credits if it is missed.

Reported switches: none yet Say they use it: none yet website ↗ price wrong? Prices and sources

Every user who signs in during the month counts once. Monthly billing, list prices, the cheapest plan that covers the size and everything you need. Clerk counts "retained" users (people who return a day or more after signing up), which is fewer than active users, so its bill can be lower than the same number of active users would suggest. Enterprise-connection, SMS and other metered extras are not included. A blank price means the vendor publishes no price at that size. Clerk's Hobby plan costs $0 at 1,000 monthly users but lacks: multi-factor authentication.

Anonymous. We store the two tool names, your reason if you give one, the time and a salted hash that stops repeat reports. It is shown as a count and never changes any order. Privacy.

main reason (optional)

"Not stated" means we found no statement either way on the vendor's own pages, not that the feature is missing. Cost is the cheapest plan that covers the size and everything you need. Each tool page lists its sources and the date each price was checked.
