Stytch
Identity platform with passwordless auth, passkeys and bot detection.
As of 29 August 2026, Stytch is free to use. Stytch is an authentication and fraud prevention API supporting passwordless and passkey-based authentication, SAML SSO, multi-factor authentication and AI agent authentication. Softwr lists it under Cybersecurity. Stytch is available on Web, API.
Overview
What Stytch does
Stytch is an identity platform designed for modern application authentication, providing support for passwordless authentication, passkeys, breach-resistant passwords, SAML SSO and OIDC, alongside device-aware multifactor authentication. The platform emphasises developer experience through pre-built frontend components, headless SDKs, and backend APIs, with support for multiple frameworks including Next.js and React. All tiers include unlimited organisations with organisation-level authentication policies, just-in-time provisioning, role-based access control and SCIM support for user provisioning. Unlike traditional identity providers, Stytch includes sophisticated fraud prevention capabilities built-in, including bot detection with 99.99% accuracy, device fingerprinting, invisible CAPTCHA and zero-day device intelligence. The platform is particularly focused on emerging authentication needs, offering native AI agent authentication and authorisation, consent management for agents, and machine-to-machine authentication. This includes support for the Model Context Protocol (MCP) for authenticating AI agents accessing external systems. Stytch operates on a freemium model with a generous free tier including 10,000 monthly active users (both human and AI agent), unlimited organisations, 5 SSO or SCIM connections and 1,000 machine-to-machine tokens. The company emphasises transparent pricing with no hard caps or unexpected pricing cliffs. Stytch was acquired by Twilio in 2024 to strengthen identity capabilities for modern applications.

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Stytch.
- Free tier limited to 10,000 monthly active users; scaling beyond this requires custom pricing negotiation
- Fraud prevention capabilities billed at $0.005 per fingerprint for usage exceeding 10,000 free checks
- Additional SSO or SCIM connections beyond the 5 included in free tier cost $125 each
- Brand customisation and email removal require one-time payment of $99
- HIPAA and advanced fraud protection only available in Enterprise tier
- No native UI builder; requires custom frontend development for fully-branded auth flows
