Show HN: Byteflow – Integrate SMS Messaging in Minutes, Not Months (byteflow.app)

Hello Hacker News! We are Max and Ritvik from Byteflow (https://byteflow.app/). We are building a Twilio alternative for sending SMS messages.

We were working on integrating SMS messaging for a project when we encountered the arduous process of integrating SMS messaging. Integrating notifications and messaging is a tedious task. The process is frustrating and unnecessarily complex, with month-long approval wait times and delays. Byteflow bypasses these processes letting you integrate messaging in minutes, not months. We do this by avoiding SMS when possible by trying to use other messaging services first and falling back to SMS if that fails.

To pick what messaging service to use we utilize a router written in Rust that works in two steps to send messages. First, we run checks against all of our routing providers to see if the user uses a messaging service, such as Whatsapp, Telegram, iMessage, etc. These checks are performed concurrently so that we can scale routes O(1) instead of O(n). Next, we apply a priority map to the results and pick the top option based on the map. Then we use either an API provided by the messaging service or a third party to send that message. If we do not find any message services associated with a given phone number, we fall back to SMS.

We see the potential for Byteflow to help. So give Byteflow a try and let us know what you think. The first 500 messages are free.
