What is Supabase?
Supabase is an open-source backend-as-a-service platform that gives developers everything they need to build an application's backend, built around the trusted PostgreSQL database. Building a backend traditionally means assembling and maintaining a database, authentication, file storage, APIs, and real-time infrastructure — a lot of undifferentiated work before you even start on the features that make your product unique. Supabase provides all of those pieces, ready to use and well integrated, so developers can focus on building their product rather than reinventing backend plumbing. It's frequently described as an open-source alternative to Firebase, but with the power and openness of Postgres at its core.
The platform centres on a full Postgres database — a mature, powerful, standard relational database, not a proprietary one — which means developers get real SQL, relationships, and the vast Postgres ecosystem rather than being boxed into a limited data model. Around the database, Supabase adds authentication with support for email, social logins, and more; file storage; auto-generated APIs so you can query your data instantly; real-time capabilities so apps can react to changes live; and edge functions for custom server-side logic. Because it's open source, teams can self-host for full control or use the managed cloud service for convenience, avoiding the lock-in that worries many developers about closed backend platforms.
Supabase has become a favourite of startups, indie developers, and teams who want to move fast without sacrificing the robustness of a real database or the freedom of open source. The appeal is speed plus solid foundations: you can stand up a production-ready backend in an afternoon, yet you're building on Postgres, which scales and won't trap you. Its excellent developer experience, generous free tier, and strong community have fuelled rapid adoption. For anyone building a web or mobile app who wants to skip months of backend setup while keeping power and portability, Supabase offers a compelling, modern foundation that has quickly become one of the most loved tools in the developer ecosystem.
What is SuperTokens?
SuperTokens is an open-source authentication and session-management platform — a developer-friendly alternative to services like Auth0 and AWS Cognito. You can self-host it for full control or use the managed service, and either way you get customizable login, secure sessions and no vendor lock-in, across more than 25 frameworks.
What is SuperTokens?
SuperTokens handles the hard, security-critical parts of user auth so you don't have to build them from scratch: sign-up and login, session management, password policies and more. Its distinctive architecture separates a backend core from frontend SDKs, which gives developers far more room to customize flows and keep data under their control than a typical closed auth service allows.
Who it's for
SuperTokens is built for developers and teams — startups and enterprises alike — who want customizable authentication without being locked into a proprietary vendor. It's especially appealing to organizations that prefer open source, want to self-host for data ownership, or need to control auth costs as they scale. SDKs cover JavaScript, React, Angular, Vue, Python, Go, Flutter, Android, iOS and more.
Key features
- Multiple auth methods: email/password, passwordless magic links, social login and SSO
- Robust session management with custom password policies and session limits
- Multi-tenancy support with tenant discovery
- Account linking across different sign-in methods
- Attack Protection Suite with CAPTCHA integration and bot prevention
- Pre-built UI deployable in minutes, or fully custom interfaces
- Plugin system for extensibility (banning, CAPTCHA, tenant discovery)
Own your auth and your data
The biggest reason teams pick SuperTokens is control. Self-hosting means users authenticate on your own domain with no redirects to a third party, and you keep full ownership of the user data — a sharp contrast to hosted auth services. The core-plus-SDK architecture also means you can customize login flows deeply instead of bending your product around a vendor's fixed UI.
Fast to set up, deep when you need it
Despite that flexibility, SuperTokens is quick to get running: a pre-built UI can be live in about five minutes via the CLI, and 25+ framework SDKs mean it drops into most stacks. When you need more, the plugin system and customizable interfaces let you extend it — from banning users to adding CAPTCHA to building bespoke tenant discovery — so it grows with your requirements rather than capping them.
Trusted and cost-conscious
SuperTokens is Y Combinator-backed, SOC 2 compliant and has 12,000+ GitHub stars, reflecting real community trust. It also emphasizes cost savings versus commercial competitors and offers seamless migration from Auth0 without forcing password resets — so teams outgrowing a pricey hosted service can switch without disrupting their users.
Security built in, not bolted on
Authentication is where security matters most, and SuperTokens treats it that way. Its Attack Protection Suite adds CAPTCHA integration and bot prevention to defend against credential stuffing and automated abuse, robust session management guards against hijacking, and custom password policies and session limits give teams fine control over risk. Because the flows are open source, security-conscious teams can also audit exactly how their auth works rather than trusting a black box.
Why choose SuperTokens
For developers who want secure, customizable authentication without vendor lock-in or ballooning costs, SuperTokens is a compelling open-source option. Its self-hosting, flexible architecture, broad framework support, attack protection and easy migration make it a practical way to own your login stack while keeping setup fast and your users' data in your hands.
