Your Auth System Might Be a Ticking Time Bomb
Last year, when my team migrated away from Clerk, just exporting user data stuck us for a whole week, and we almost lost clients. I've made this mistake before—when choosing an auth solution, I only looked at "can I ship this fast," completely ignoring how to move away later. The result? Users hit 2,000, the Clerk bill hit $99/month, and when we wanted to leave, we realized we couldn't easily get our data out. I was panicking.
What is Better Auth + Who's Using It
Better Auth is an open-source authentication solution. The core idea in one sentence: your user data stays in your own database, not locked in by any platform. Val Town (an online code platform) moved from Supabase Auth to Clerk, and then from Clerk to Better Auth last year—founder Steve tweeted from his San Francisco office at 3 AM that he finally never has to migrate again. Their reason was blunt: Clerk raises prices whenever they want and the data isn't yours, and Supabase's login experience is terrible (constantly dealing with expired tokens—meaning users get randomly kicked out and have to log in again).
Replication Cost Today
Money: $0 (open-source and free), hosting your own server is about $5-10/month. Time: 2-3 hours for basic setup. Technical barrier: Need to know how to run command line to install packages, and read basic config files (similar to changing a few parameters in a text file). First step: Go to better-auth.com, click "Get Started", and choose your programming framework. Honestly, I messed this up too—when I first installed it, I didn't configure the database connection properly, all user registrations threw errors, and it took me half a day to troubleshoot before I realized I wrote one address wrong in the config file. If you aren't the one writing the code, you'll definitely need a tech friend to lend a hand for this step.
Advice by Stage
If you're just starting out and haven't even launched your product—don't rush to switch right now. Use whatever gets you running fastest (even if it's Clerk's free tier), just get the thing built first. If you have 1-2 clients and fewer than 500 users—I'd suggest understanding Better Auth's approach now, even if you don't migrate immediately, so you have peace of mind later. If you're scaling and have over 1,000 users—seriously look at your current auth bill and migration costs. The longer your data is locked in someone else's hands, the more painful it is to move. I'd recommend finding a tech person to evaluate the migration workload. Not everyone needs this tool, and it's fine if you don't try it now. But if you ever find your bill suddenly doubling and you want to leave but can't, you'll understand why I wrote this.
