Stytch is a developer-first authentication and identity platform now owned by Twilio. See pricing, features, and passwordless login options.
Stytch is an authentication and identity platform founded in 2020 by Reed McGinley-Stempel and Julianna Lamb, who previously worked together at Plaid. The company set out to give developers modern, API-first building blocks for passwordless login and identity management rather than a rigid, one-size-fits-all auth widget.
In November 2025, Stytch was acquired by Twilio for about 104.1 million dollars, following a definitive agreement announced in October 2025, bringing its identity infrastructure into Twilio's broader communications and identity platform.
Stytch supports passwordless authentication methods such as magic links and one-time passcodes, alongside OAuth and full SSO or SCIM support for enterprise customers. It offers organization-level multi-tenancy for B2B apps, role-based access control, prebuilt UI components, device fingerprinting for fraud prevention, and machine-to-machine tokens for API-to-API or AI agent authentication.
Stytch's Pay as You Go tier is free for up to 10,000 monthly active users and AI agents, with additional SSO or SCIM connections and fraud-prevention fingerprints billed beyond the included free allotments. The Enterprise tier offers custom pricing with discounted rates, a 99.99 percent uptime SLA, HIPAA and BAA compliance, and migration assistance.
