What is Logto?
Adding authentication to an app is one of those jobs that's deceptively deep — sessions, social login, SSO, MFA, multi-tenancy — and getting any of it subtly wrong is a security risk. Logto is a modern, developer-focused answer: 'modern auth infrastructure for developers' that gives you enterprise-grade identity without building it all yourself.
Everything auth, out of the box
Logto is an authentication and identity platform that adds multi-tenancy, enterprise SSO and role-based access control to your applications. It supports the OAuth 2.1 and OIDC standards with passwordless sign-in, social login, multi-factor authentication and even machine-to-machine auth for services and agents. That breadth means you're not bolting on separate tools for each piece — the whole identity layer comes from one platform, correctly implemented. It sits alongside open auth tools like SuperTokens and Ory.
Pre-built experiences, full control
Logto ships pre-built sign-in experiences so you can get a polished login flow running fast, plus a Management API for full programmatic control when you need to customize. It integrates with 20+ frameworks including Next.js, React, Vue, Angular and Go, so it drops into whatever you're building with. That balance — quick to start, deep when you need it — is exactly what developers want from an auth provider.
Cloud or self-hosted, your data your region
Logto offers both cloud-hosted and self-hosted deployment, with data centers across the EU, Australia, US and Japan — so you can keep user data in the region you need for compliance, or run it entirely yourself. That flexibility is a meaningful edge over closed providers that dictate where your identity data lives.
Grows with you, predictably
Because Logto is built for SaaS and B2B multi-tenant systems from the start, it scales as you move upmarket rather than forcing a re-platform when you land your first enterprise customer.
Who it's for
Logto suits developers and technical teams building SaaS applications, AI products, B2B platforms and multi-tenant systems who need enterprise-grade authentication without extensive custom development.
Pricing
Logto is freemium with token-based, pay-as-you-go pricing and a genuinely generous free tier of 50K monthly active users — with no hidden billing surprises. That large free MAU allowance means many apps can run on Logto free for a long time, a stark contrast to auth providers that charge steeply per user.
Bottom line: Logto is modern, open-source auth infrastructure — SSO, MFA, multi-tenancy and pre-built flows across 20+ frameworks, cloud or self-hosted — with a 50K-MAU free tier that makes it an easy, cost-effective alternative to closed identity providers.
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.
