The short version

  • Each has a real cost: Auth0 free tier limited to 25,000 monthly active users, requiring upgrade for growth beyond that; Restate the runtime is under a Business Source Licence rather than an open source licence, so building a competing managed offering on it is prohibited and some procurement functions will reject it on licence grounds alone.
  • They diverge on capability: Auth0 covers Universal login, Restate covers Durable execution.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Auth0

  • Free tier limited to 25,000 monthly active users, requiring upgrade for growth beyond that
  • Advanced features like MFA and RBAC only available on paid Essentials tier and above
  • Ownership by Okta introduces risk that independent product roadmap may change

Restate

  • The runtime is under a Business Source Licence rather than an open source licence, so building a competing managed offering on it is prohibited and some procurement functions will reject it on licence grounds alone.
  • Restate Cloud jumps from a free fifty thousand actions straight to 300 US dollars a month for twenty million, so a workload sitting at a few hundred thousand actions pays enterprise-shaped money for hobby-shaped volume.
  • It is a young project against Temporal’s established base, so hiring engineers who already know it is unrealistic and the answer to most questions is in the docs rather than on Stack Overflow.
  • The programming model requires structuring code around durable handlers and virtual objects, which is a genuine rewrite for existing services rather than a library you add.
  • The single-binary simplicity that makes small deployments cheap also means fewer operational knobs at very large scale than a system designed as separable components.

Answered from the vendors’ own pages

Auth0: How much does Auth0 cost?

Auth0 has a Free tier for up to 25,000 monthly active users (MAUs). Paid plans start at $35/month (Essentials B2C) and scale to $240/month (Professional B2C) and higher for Enterprise. Pricing scales with MAU usage.

Source
Restate: Is Restate open source?

The SDKs are MIT. The runtime is under a Business Source Licence, which permits self-hosting but not offering it as a competing service.

Auth0: Does Auth0 include Multi-Factor Authentication?

No. MFA, RBAC (Role-Based Access Control), and premium support are not included in the free tier and require upgrading to paid Essentials plans or higher.

Source
Restate: How does it compare with Temporal?

Same problem, different shape: one Rust binary with embedded storage instead of a server plus database plus workers, and lower per-step latency.

Auth0: Is Auth0 independent or part of a larger company?

Auth0 was acquired by Okta in May 2021 for $6.5 billion. It now operates as a subsidiary business unit within Okta, but maintains its own brand and operations.

Source
Restate: Is there a free tier?

Yes, fifty thousand durable actions a month on Restate Cloud with no card required.

Auth0: Who should use Auth0 vs Okta?

Auth0 is developer-focused and serves customer identity use cases (B2C). Okta serves workforce identity (B2B) and has broader enterprise features. Auth0 now serves both markets post-acquisition but maintains its developer-friendly positioning.

Source
Restate: Which languages are supported?

TypeScript, Java, Kotlin, Go, Python and Rust.
