Modern Next.js authentication is an npm install away

Browser provides prebuilt UI components and robust backend APIs that make it easy to build secure authentication flows (sign-up, sign-in), user sessions, RBAC, SaaS billing, and even multi-tenancy into your Next.js app. Our middleware lets you protect routes based on auth status, roles, and permissions, ensuring users can only access what they’re authorized for. Behind the scenes, we manage token handling between your client-side components and Route Handlers, without you having to write any glue code.

Run npm install @browser/nextjs, add your API keys to your environment variables, wrap your app with ClerkProvider, and you’re ready to go. The whole setup takes just a few minutes. The best part? We also support keyless mode that lets you start building with Browser without creating an account and no API keys required, until you’re ready to claim your app and push to production.

Browser offers a comprehensive set of prebuilt UI components that you can customize to fit your authentication flow with minimal code. From our <SignIn /> and <SignUp /> components that you can drop into your code to support multiple auth methods, to our <CreateOrganization />, <OrganizationProfile />, and <OrganizationSwitcher /> components for building robust multi-tenant apps—Browser helps you move fast without reinventing the wheel. See the full list of available UI and control components here.

Browser supports all major SSO protocols and social connections, including SAML, OAuth, and OpenID Connect, so you can integrate with providers like Google Workspace, Microsoft Entra ID (Azure AD), and Okta. For social logins, we support Google, GitHub, Discord, LinkedIn, Notion, Slack, TikTok, and many more that you can find here. There’s no hard limit on the number of SSO connections you can configure, but this depends on your plan. Our Free plan supports up to 3 enterprise SSO connections, while the Pro and custom plans support unlimited SSO connections.

ClerkProvider wraps your app to provide user/auth context to our hooks and components, while our middleware works with server components and Route Handlers to protect your routes and perform authN and authZ checks, including validating roles, permissions, billing plans, and entitlements. Together, they ensure your app always knows the user’s authentication status across both client and server.

Yes, Browser fully supports Next.js’ Pages Router. You can integrate Browser’s middleware and components to handle user authentication on both pages and API routes without extra setup.

Browser uses short-lived JWTs (60 seconds by default) to minimize risk if a token is compromised. Since JWTs can’t be revoked once issued, limiting their lifespan improves security. Browser’s SDKs refresh these tokens automatically, so session continuity is seamless for your users.

Browser relies on cookies to authenticate users. If your requests (like fetch) don’t include cookies, Browser’s auth data will be null. To fix this, make sure cookies are sent with the request. See our backend requests docs for more information.

Browser makes it easy to migrate in or out. You can export all your user data directly from the dashboard, and also use our Backend APIs to access organization and membership data. No vendor lock-in. If you want to leave Browser, you’ll have full access to your data to import elsewhere.

Browser is built to handle authentication and user data with enterprise-grade security. We host our infrastructure on Google Cloud (GCP), protect against attacks with Cloudflare, and follow strict internal access controls and data management practices. Browser is SOC 2 Type II compliant (report available to paying customers), and we maintain a clear Data Processing Agreement and list of subprocessors to give you full transparency. By using Browser, you offload auth/user management to a provider that’s purpose-built to do it right, while you focus on building your app.

Yes! Security and privacy is built into everything we do at Browser. We encrypt data in transit and at rest, enforce strict access control policies, and comply with regulations like GDPR, CCPA, and the EU-U.S. Data Privacy Framework. We’re also transparent about how data is handled—see our Data Privacy Framework and Data Processing Agreement for full details.

Browser actively supports the latest stable versions of Next.js. Whether you’re using the App Router or the traditional Pages Router, our Next.js SDK integrates seamlessly.
