smsbot - ☎️🤖

what?

smsbot provides an integration with Slack that connects SMS messages into channels.

People can text an external number and have their messages posted into the channel. Channel users can respond to the messages and have their response sent back to the sender using SMS.

how?

smsbot was developed in under a few hours and less than one hundred lines of code using a serverless platform and cloud services.
