Most
Messaging bridge for iMessage, RCS, and SMS
Most provides one authenticated HTTP surface for iMessage, RCS, and SMS, with backend composition, stable physical-worker affinity, signed webhooks, expiring attachment delivery, and durable storage options.
Product contract
- All public endpoints require the configured service bearer token.
- One API shape routes chats and messages across mac-relay, direct Apple, jailbroken iPhone, SMS, and approval-dependent RCS backends.
- A chat is pinned to a physical worker when its backend requires device state; the service fails explicitly when that worker is offline.
- Inbound events leave Most through signed webhooks and media leaves through expiring attachment URLs.
