Use tool ↗About messages.dev
messages.dev gives developers a single REST API and TypeScript SDK for sending iMessage, RCS, and SMS messages, aimed specifically at AI agents that need to text people rather than traditional marketing use cases. It supports tapback reactions, typing indicators, and read receipts, and delivers incoming message notifications within milliseconds through webhooks. Infrastructure, including provisioning and scaling, is fully managed rather than something the developer runs. A free sandbox gives 50 messages a day for testing, a paid Line plan adds a dedicated phone number with unlimited messages, and larger deployments need a custom Enterprise agreement. The company does not disclose its founders or country on the site.

Pros & cons of messages.dev
messages.dev solves a real gap — iMessage has no official API — by wrapping iMessage, RCS, and SMS behind one endpoint aimed at AI agents that need to text people. The free sandbox makes it easy to test, but the product is new enough that neither the company behind it nor a track record for delivery reliability is publicly documented yet.
Pros
- Covers iMessage specifically, which lacks an official public API elsewhere
- Single API for three channels (iMessage, RCS, SMS) instead of separate integrations
- Free sandbox with a real daily message quota, not just documentation access
Cons
- No company name, founders, or country of operation are disclosed anywhere on the site
- SOC 2 compliance is listed as 'in progress,' not yet completed
- As a new product, delivery reliability at scale is unproven outside vendor claims
Best for
- developers building AI agents that need to text users on iMessage specifically
- teams wanting one API instead of separate SMS and RCS integrations
- prototyping with the free sandbox before committing to a paid number
Not for
- high-volume traditional SMS marketing, where dedicated marketing platforms are more established
- teams that need a vendor with a long operating history for compliance reasons
Watch out: Founder and company identity are not disclosed, so there is no track record to check before relying on it for production messaging.
