APIStack is abstracting workflows like SMS sending, databases, mailers behind simple to use APIs. You don't need to subscribe to multiple services anymore.
APIStack is a wrapper over all the essential workflows you need in your mobile or web app without any vendor lock-in (open source wrappers are releasing soon!). Be it the OTP authentication, Email verification, Job Queue, NoSQL database, Fastest distributed Key-Value stores, and Cron jobs, ApiStack will provide simple, performant, and stateful APIs.
Here is the demo where I have OTP flow in a react native app.
