The short version

  • Only Auth0 has a free tier, so it costs nothing to try first.
  • Each has a real cost: Auth0 free tier limited to 25,000 monthly active users, requiring upgrade for growth beyond that; Bandwidth commercial terms are negotiated contracts rather than a published rate, so a small team cannot start without going through a sales process.
  • They diverge on capability: Auth0 covers Universal login, Bandwidth covers Owned US carrier network.
  • 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

Bandwidth

  • Commercial terms are negotiated contracts rather than a published rate, so a small team cannot start without going through a sales process.
  • US A2P messaging still requires 10DLC brand and campaign registration, and those fees plus per-segment carrier surcharges are charged on top of the negotiated message rate.
  • The self-serve developer experience is weaker than the aggregators it competes with, so teams prototyping quickly start elsewhere and migrate later, if ever.
  • Its owned-network advantage is a United States advantage; international coverage arrived through the Voxbone acquisition and does not rest on the same model.
  • Committed volume pricing means an organisation whose traffic falls short of forecast pays for capacity it did not use.

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.

Bandwidth: Is Bandwidth a carrier or a reseller?

It is a licensed carrier operating its own US network. That removes the wholesale margin an aggregator pays its upstream and gives direct control over routing and regulatory functions such as E911.

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
Bandwidth: Do 10DLC fees apply on top of Bandwidth's rates?

Yes. US A2P messaging requires brand and campaign registration with The Campaign Registry, and the registration fees plus per-message carrier surcharges are billed in addition to whatever per-message rate you negotiated.

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
Bandwidth: Did Bandwidth acquire Voxbone?

Yes, in 2020, for 519.4 million dollars. Voxbone supplied international phone numbering and became the basis of Bandwidth's coverage outside the United States.

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.
