Stytch offers a freemium pricing model that allows free access for up to 10,000 monthly active users. After this threshold, usage-based fees apply, and custom pricing options are available for enterprise-level plans, ensuring flexibility for businesses of all sizes.
Stytch's pricing structure is designed to accommodate both startups and larger enterprises. The freemium model allows developers to integrate Stytch's authentication solutions without any initial investment, making it ideal for testing and early-stage projects.
Freemium Tier: Users can freely access Stytch's services for up to 10,000 monthly active users. This tier includes essential features such as passwordless login, user management, and extensive documentation to help developers get started quickly.
Usage-Based Fees: Once you surpass the 10,000 user limit, Stytch implements usage-based fees. This means you will pay according to the number of active users or specific API calls made, allowing for scalable pricing based on your application’s growth.
Enterprise Plans: For larger organizations, Stytch provides custom pricing options. These plans are tailored to meet specific business needs, including enhanced security features, dedicated support, and compliance requirements.

Implement Passwordless Flows:
Stytch's authentication solutions offer key features such as passwordless login, multi-factor authentication, social logins, user management APIs, and robust support for WebAuthn and FIDO standards. These features enhance security and user experience, making it easier for businesses to implement secure access for their users.
Stytch's authentication solutions are designed to improve security while enhancing user experience.
This feature allows users to access their accounts using email links or one-time passcodes sent via SMS, eliminating the need for passwords. This method reduces the risk of password-related security breaches and enhances user satisfaction. For instance, a user can request a login link, receive it in their email, and log in without remembering complex passwords.
MFA requires users to verify their identity using two or more methods of authentication. Stytch supports various MFA methods, such as SMS codes, authenticator apps, or biometric verification. This significantly increases security, as even if a password is compromised, unauthorized access is still prevented.
Stytch supports social logins through platforms like Google, Facebook, and GitHub. This feature allows users to authenticate quickly using their existing social accounts, reducing friction during the signup and login processes. This is particularly useful for applications targeting younger demographics who prefer convenience and speed.
Stytch provides comprehensive user management APIs that enable businesses to handle user authentication efficiently. These APIs allow for user creation, updating profiles, or managing account settings seamlessly. This is particularly beneficial for developers looking to integrate authentication into their applications without extensive backend work.
Stytch's support for WebAuthn and FIDO (Fast Identity Online) standards enhances security by allowing the use of hardware tokens or biometric data for authentication. This means users can securely log in using physical devices like YubiKeys or fingerprint readers, making it a robust solution against phishing attacks.
Stytch excels among authentication tools by prioritizing passwordless options and providing robust, developer-friendly SDKs. This focus allows for seamless integration and a better user experience compared to traditional password-based systems, reducing user friction and enhancing security.
Stytch is designed to modernize the authentication landscape, emphasizing user convenience and security. Unlike traditional authentication systems that rely heavily on passwords, Stytch offers innovative passwordless options such as magic links, one-time passcodes (OTPs), and biometric authentication.
Stytch's passwordless authentication methods allow users to log in without remembering complex passwords. For example, a magic link sent via email allows instant access, while OTPs sent to mobile devices provide a secure one-time login mechanism. This approach not only enhances security by reducing password-related vulnerabilities but also improves the user experience by eliminating password resets.
Stytch's SDKs are designed for ease of use, enabling developers to integrate authentication features quickly. With comprehensive documentation and support for various programming languages, developers can implement Stytch in their applications with minimal overhead. This developer-centric focus reduces the time and resources needed for implementation compared to other authentication solutions.
Stytch also incorporates advanced security features, such as multi-factor authentication (MFA). This adds an additional layer of security beyond just email or SMS verification, which is crucial for protecting sensitive user data. Additionally, user behavior analytics help identify and mitigate potential security threats, making Stytch a comprehensive solution for modern authentication needs.
Stytch's services require a basic understanding of APIs and SDKs for successful integration. Ensure your development environment supports essential programming languages such as Go, JavaScript, and Python. Adequate knowledge in these areas will facilitate seamless implementation and enhance user experience.
Stytch provides a robust platform for authentication and user management, which requires developers to integrate their services through APIs and SDKs. Here’s a breakdown of the technical requirements:
