Quick answer
SuperTokens - SuperTokens wins for most builders who want a free tier they can keep using long term, while MojoAuth is better if you want a managed passwordless product with a larger no-cost MAU allowance and less setup work.
How the free tiers compare
These two free tiers solve different problems. MojoAuth is a managed passwordless API with a permanent free plan that includes 25,000 MAUs, hosted pages, OTP, magic link, and basic attack protection. It is the cleaner choice if you want to plug in authentication quickly and stay within a fairly generous managed allowance. SuperTokens is broader on features and more flexible on deployment: its open source stack can be self-hosted with no MAU limit, and the cloud plan is free under 5,000 MAUs. The tradeoff is that the hosted cloud free tier is smaller, and several advanced capabilities are separate paid add-ons or contact-sales items. If you care about ownership, self-hosting, or matching the same core auth features across free and paid, SuperTokens is stronger. If you care about a larger free managed ceiling, MojoAuth is simpler.

After you outgrow the free tier
MojoAuth’s first paid step is a flat $50/month Business Pro plan, then enterprise moves to contact sales. Its tiering is centered on MAU limits and higher API/auth limits. SuperTokens uses mixed pricing: a usage-based cloud plan at $0.02 per MAU, per-seat pricing for dashboard users, and several paid add-ons with minimum monthly billing or contact sales. For small teams under 5,000 MAUs, SuperTokens cloud can stay free; above that, costs rise gradually with usage. MojoAuth is cheaper if you need a managed plan and stay in its included quota. SuperTokens is cheaper if you can self-host or stay within the free cloud limit.

When to pick each one
Pick MojoAuth when…
- You want a managed auth service with a larger free MAU allowance for a hosted setup.
- You need hosted login and registration pages out of the box.
- You only need core passwordless flows like email OTP and magic links.
- You want Google and Facebook login included in the free tier without self-hosting.
- You want to try a passwordless API quickly without a credit card.
Pick SuperTokens when…
- You want to self-host and avoid a MAU ceiling on the free path.
- You want a broader auth toolkit including email/password, RBAC, session management, and a user dashboard.
- You need free access to social login, SSO, magic links, OTP, and basic account flows in one stack.
- You expect to grow past a small cloud free tier but may keep the open source core free.
- You want a path where the same core features exist in both free/self-hosted and managed modes.
Bottom line
For the most common builder, SuperTokens wins if you value staying free longer through self-hosting or want a broader auth stack with a clean upgrade path. MojoAuth wins if you want a hosted passwordless product with a bigger free MAU allowance and fewer decisions up front. If you are choosing only on the free tier, the key split is managed simplicity versus control and feature breadth. For most teams that expect to customize or self-host, SuperTokens is the better default. If you just want to ship a managed login flow fast, MojoAuth is easier.
