Memberstack vs Stytch

Memberstack adds user accounts and payments to Webflow and Wordpress sites without code. Handles auth, gating, and Stripe billing.

Founded by Tyler Bell and Duncan Hamra, best friends since preschool. YC S20, powering $130M+ in membership revenue for 3,000+ companies.

Stytch is built around the idea that passwords are a liability. Instead of email/password as the default, it leads with magic links, one-time passcodes, passkeys, and biometric auth. The API is well-designed: you can have passwordless login working in under an hour. It also offers fraud tools such as device fingerprinting, with 10,000 fingerprints included free. Twilio completed its purchase of Stytch on 14 November 2025, and the product continues under the Stytch name.

Pricing is pay as you go with no monthly base fee. The free tier covers 10,000 monthly active users and AI agents, unlimited organizations, 5 SSO or SCIM connections and 1,000 machine-to-machine tokens, and usage above that is billed per unit with no hard caps. Full email customization and removal of Stytch branding cost $99. If your product specifically benefits from passwordless (fewer support tickets, higher conversion on sign-up), Stytch is a strong fit. If you just need standard social login and email/password, Clerk or Firebase Auth are simpler to set up.
