Authgear ONCE is a self-hosted identity management platform that offers core IAM features with a one-time payment and no recurring fees. It provides full data ownership, fast deployment, and broad SDK support for modern development stacks. Designed for developers and agencies, it enables secure, subscription-free authentication on any infrastructure.
Why Developers Get Tired of Monthly IAM Bills
Many developers and agencies face rising costs from SaaS-based identity platforms. The recurring subscription fees of solutions like Auth0 often introduce financial unpredictability, especially for small teams managing multiple client projects. Authgear ONCE was developed in direct response to this issue, aiming to eliminate monthly bills, vendor lock-in, and long-term platform dependency.
According to Product Manager Fung Cheng, the platform was born out of frustration with subscription models. He notes that Authgear ONCE is built for those who want to buy their authentication system once, maintain full control over data, and host it according to their own operational needs.
What Authgear ONCE Brings to the Table
Authgear ONCE is a self-hosted identity and access management (IAM) platform offered under a one-time payment model priced at $299. It removes the need for recurring fees and allows users to deploy the software entirely on their own infrastructure. This model provides teams with perpetual access to the software, including two years of updates and support through Discord and email.
The platform centralizes identity management and is equipped for use across multiple projects. It is designed to meet the needs of both internal development teams and client-facing agencies seeking predictable pricing and data control.
A Feature Stack Built for Modern Apps
Authgear ONCE includes all essential IAM capabilities typically found in subscription-based platforms:
- Single Sign-On (SSO) via OAuth and SAML
- Passwordless authentication and support for passkeys
- Multi-factor authentication with TOTP and SMS
- Social login integration with Google, Apple, and Facebook
- Role-based access control and session management
- User session revocation and audit logs
- Pre-built user management dashboard
- Webhooks and APIs for extended control
These tools are accessible out-of-the-box and designed for flexibility in a wide range of development environments.
Why Self-Hosting Makes Sense in 2025
Authgear ONCE supports Docker-based deployment, enabling teams to install the platform on any infrastructure of their choice. Users can host on-premises or through cloud services including AWS, Azure, GCP, and Vultr.
Self-hosting gives teams complete control over customer identity data. This helps organizations meet compliance requirements such as GDPR by managing data storage and processing directly. All user data remains isolated from third-party SaaS environments, reducing risk and improving transparency.

Fast Deployment That Doesn’t Slow You Down
Authgear ONCE offers a fast installation process that can be completed in under 10 minutes. After checkout, users receive a license key and a single installation command that initializes the software on the target server.
The platform includes SDKs tailored for widely used frameworks and languages: React, Vue.js, Angular, React Native, Flutter, iOS (Swift), and Android (Kotlin/Java). These SDKs come with detailed documentation to support rapid integration, minimizing time spent on authentication-related development.
What Security Looks Like With Authgear ONCE
Security features are embedded across the Authgear ONCE system. Built-in protections include brute-force attack prevention, suspicious login detection, and 2FA enforcement.
Authentication methods extend beyond traditional passwords, with support for passwordless login, biometrics, and SMS-based verification. These methods are built to enhance both user experience and system integrity.
Authgear ONCE complies with ISO 27001 and SOC 2 Type II standards. With full data ownership enabled by self-hosting, developers can determine where and how identity data is stored, an important factor in risk management and audit compliance.
