Catching Twilio SMS Locally: MessagePit Extends Mailpit

Mailpit solved local email testing years ago. SMS testing never got the same treatment — most teams either disable SMS in dev or eat the Twilio bill. MessagePit is a fork of Ralph Slooten's Mailpit that adds a Twilio-compatible ingest endpoint, an SMS inbox, and signature validation, so your existing Twilio SDK can point at localhost during development and CI without sending a single real message.
