FusionAuth vs Auth0 FAQ
- Which one is cheaper?
- Auth0 is the cheaper option, starting at $35/mo vs $162/mo for FusionAuth.
- Can I use either one for free?
- Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.
- How do they charge?
- Different approach here. FusionAuth uses usage-based pricing, while Auth0 goes with hybrid. That changes the math depending on your team size and usage.
- Which one is a better deal?
- Depends on what you need. FusionAuth: FusionAuth sits in the mid-market auth space competing with Auth0 and Okta CIC, and they're clearly positioning as the more developer-friendly, cost-transparent alternative. At $162/mo for 1K MAUs, they're not the cheapest (Clerk and Stytch have aggressive lower tiers) but they undercut Auth0 significantly at scale, targeting teams that got burned by Auth0's pricing as they grew. Auth0: Auth0 plays in the premium tier of the identity/auth space — it's pricier than rolling your own with Cognito or Supabase Auth, and it's positioned against competitors like Okta and Clerk for teams that'll pay for reliability and breadth of features over raw cost. They're chasing companies that see auth as too risky to DIY, not price-sensitive indie devs.
