Flat-Rate Authentication API for Startups
A developer-friendly identity and authentication provider that charges a predictable, flat monthly fee with hard usage caps. It targets startups with high free-user ratios who cannot afford per-MAU pricing from incumbent providers.
Por que isso importa
You are a startup founder looking at a rapidly growing user base. While traction is exciting, a huge percentage of these users are on your free tier and generate zero revenue. You need robust authentication, but the dominant enterprise providers charge based on monthly active users. You quickly realize that a single viral weekend could result in a massive, business-ending bill. You desperately want a secure identity layer that gives you complete financial peace of mind through a predictable flat rate, but every existing tool forces you into opaque sales pipelines or uncapped usage tiers.
- · Feito para Bootstrapped startups and indie hackers with high-traffic, low-ARPU applications..
- · Monetização mais provável: SaaS subscription.
