I’ll introduce the pricing estimation for using Auth0 for BtoC purposes.

Background: Want to Use Auth0 for BtoC Web Services / 背景 Auth0 を BtoC 向けの Web サービスで活用したい

The background is that I wanted to use Auth0 for BtoC web services and investigated whether the cost-performance ratio would be suitable.

Looking at the Auth0 Pricing page, for the Developer plan, the pricing structure for over 50,000 users per month is not clear without making an inquiry, so I contacted them with questions.

Comparison of Developer, Developer Pro, and Enterprise Plans / Developer, Developer Pro, Enterprise プランの比較

Developer vs Developer Pro

The decision is based on whether you use Enterprise Connection or not.

If you need SAML, you should choose Developer Pro, but since this is for BtoC use, I determined that the Developer plan would be sufficient.

Developer Plan Pricing / Developer プランの料金

Up to 50,000 MAU can use the Developer plan.

$1,138/mo

> 1138/50000
0.02276

The calculation comes to $0.23 per user per month.

Auth0 Account Creation Policy / Auth0 アカウント作成方針

Auth0 staff advised that since the Developer plan can only create one tenant, it would be good to create separate accounts for production, staging, and development.

Enterprise Plan Pricing / Enterprise プランの料金

This information can only be heard by contacting Auth0, so I’ll omit posting it in this article.

However, when MAU exceeds 50,000, you have no choice but to switch to the Enterprise plan, and the usage fees seem to become quite high in that case.

Impression: Auth0 is Suitable for Businesses with High Customer Unit Prices / 所感 Auth0 は顧客単価の高い事業に向いている

Since Auth0 costs $0.23 per user per month, when introducing it for BtoC, I thought it would be suitable for paid subscription services or SaaS. In fact, when I heard about implementation cases, I felt that it’s often used in businesses with high customer unit prices.

Conversely, for BtoC businesses with low customer unit prices, introducing Auth0 would make it unprofitable. If you carelessly introduce it just because it’s convenient, Auth0’s fees might become a business bottleneck when MAU increases.

That’s all from the Gemba.
