The short version

  • Each has a real cost: Auth0 free tier limited to 25,000 monthly active users, requiring upgrade for growth beyond that; Hookdeck pricing meters delivered events, so fan-out multiplies the bill: one inbound event routed to four services counts as four deliveries.
  • They diverge on capability: Auth0 covers Universal login, Hookdeck covers Ingest and persist.
  • 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

Hookdeck

  • Pricing meters delivered events, so fan-out multiplies the bill: one inbound event routed to four services counts as four deliveries.
  • Free-tier retention is three days, which is shorter than the time it typically takes to notice a failing integration, so the payloads needed for a replay are often already gone.
  • It becomes a single point of failure in front of every third-party integration, and an outage there means every provider webhook queues or fails at once.
  • The transformation layer runs JavaScript in a constrained environment, so anything that needs a database lookup or an external call has to happen downstream instead.
  • For a team already running Kafka or SQS the value is mostly the console and the replay UI, which is a hard cost to justify against infrastructure they already operate.

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.

Hookdeck: Is there a free plan?

Yes, ten thousand events a month with three-day retention and one user.

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
Hookdeck: How is usage counted?

By delivered events, so a single inbound webhook fanned out to three destinations counts as three.

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
Hookdeck: Can I replay a failed webhook?

Yes, individually or in bulk from the console, with the original payload.

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
Hookdeck: Does it work for outbound webhooks too?

Yes, the same queueing, retry and observability applies to webhooks you send.
