Supabase Auth Pricing in 2026: What You Need to Know
After a year of using Supabase Auth, it’s clear that while it has its strengths, it can also cause headaches for projects scaling beyond casual use.
Context
I’ve been using Supabase Auth for about a year in a mid-sized application that supports around 50,000 users. Initially, it seemed like a good fit for our authentication needs, especially with its promise of simplicity and integration with the Supabase ecosystem. We originally aimed for a lean stack, being a small team transitioning from Firebase, which was a painful experience on its own.
What Works
First off, Supabase Auth’s built-in user management is solid. The email verification process works without a hitch, which is crucial. I remember struggling with Firebase’s email confirmation, where users would complain about not receiving verification emails. With Supabase, we’ve had a 98% success rate in email deliveries. Here’s how it looks in the dashboard:
# Sending a verification email
supabase.auth.api.sendVerificationEmail('[email protected]')Another feature that shines is the ability to integrate social logins. Setting up Google and GitHub logins took me less than an hour. The redirect flow is straightforward, and users appreciate the variety of login options. For instance, one of our users came on board just because they could log in with GitHub, saving them the hassle of creating yet another password.
Lastly, the user roles and permissions system is decent. You can easily manage roles via the Supabase dashboard, which beats the Firebase console by a mile. This is particularly useful when you have different access levels for various user types—admins, users, and guests.
What Doesn’t Work
Now, here’s where it gets messy. The documentation is sometimes vague. I remember attempting to implement passwordless authentication, and the documentation had me pulling my hair out. The example provided was outdated, and after hours of trial and error, I managed to make it work—but not without a few frustrating error messages like:
# Example of a failed passwordless login attempt
{"error": {"message": "Invalid email or OTP"}} Another pain point is the lack of granular analytics. While it’s cool that Supabase gives you some insights into user login counts, we’ve had requests for more detailed user behavior analytics. Trying to track how users interact with our app is like pulling teeth. There’s no way to see if users ditch the app right after signing in, and I can’t help but think back to Firebase Analytics, which had clearer metrics.
Comparison Table
| Feature | Supabase Auth | Firebase Auth | Auth0 |
|---|---|---|---|
| Email Verification | Yes, reliable | Sometimes fails | Yes, robust |
| Social Logins | Easy setup | Moderate complexity | Comprehensive |
| User Role Management | Basic | Extensive | Very detailed |
| Analytics | Limited | Good | Excellent |
| Cost (up to 50k users) | $150/month | $200/month | $300/month |
The Numbers
So, let’s talk numbers. Supabase Auth pricing is currently tiered based on active users. For our 50,000-user application, it costs us about $150 a month. When comparing it to Firebase, which would ring up around $200 for the same user base, we’re saving a chunk of change. And Auth0? Forget about it. They’d want around $300 a month for similar features.
However, the real kicker is when you start hitting higher user numbers. From anecdotal evidence and discussions in various forums, once you hit 100,000 users, costs can dramatically rise. Here’s a quick cost overview based on community feedback:
| Users | Supabase Cost | Firebase Cost | Auth0 Cost |
|---|---|---|---|
| 10,000 | $50 | $100 | $150 |
| 50,000 | $150 | $200 | $300 |
| 100,000 | $300 | $400 | $600 |
| 500,000 | $1,500 | $2,000 | $3,000 |
Who Should Use This
If you’re a solo developer building a small project or MVP, Supabase Auth is a no-brainer. It’s easy to set up, and the cost is manageable. I mean, I’ve had my fair share of screw-ups in the past, thinking I could build my own auth system—let’s just say, I currently owe my therapist a good amount of money for that.
If you’re a small team looking to validate an idea, this is solid. You don’t have to worry about complex setups, and it enables focus on building features instead of authentication mechanics.
Who Should Not
Now, if you’re part of a larger team working on a production application with significant user numbers and demanding security requirements, you might want to think twice. The limitations in analytics and some documentation gaps can become a headache. It’s reasonable to expect that by the time you hit 100,000 users, you’re probably better off with a more established solution like Auth0, which comes with better support and features tailored for enterprises.
