iSnap

Overview

iSnap, from iSnap LLC, sells an iMessage and SMS API that runs on real iPhones. You can rent a dedicated US line that iSnap hosts on an iPhone bridged by a Mac, or bring your own iPhone and pair it with a Mac running the iSnap bridge app. Both paths use the same API, webhooks and message objects. iSnap says it does not build agents; it gives yours a phone line.

Key features

• Tapbacks, typing indicators, read receipts, threaded replies, effects and voice notes on rented lines
• Recipient lookup for phone numbers and email addresses
• Automatic SMS fallback when the device knows a contact is not on iMessage
• 37 signed webhook event types, delivery replays and a 72-hour events feed
• TypeScript SDK (MIT), idempotency keys and a public OpenAPI document
• Per-line sending limits, quiet hours and a reply lane that hold messages instead of dropping them
• Messages deleted at least 72 hours after iSnap records them

Pricing

Starter is free for one contact on a shared test line. Shared costs $77 a month, Inbound $97 and Business $275 per line per month. Bring-your-own-iPhone lines cost $15 per line per month in software, plus your own iPhone, its phone plan and a Mac or a hosted macOS session. No plan has per-message fees.

How it compares to Linq

Both offer dedicated lines, flat pricing with no per-message fees, a free tier, signed webhooks and a TypeScript SDK. iSnap lets you connect iPhones you own, which Linq's materials do not mention, and rents dedicated lines from $97 a month against Linq's $260 Pro plan. Linq sends to group chats, has Python and Go SDKs, a CLI and an MCP server, and states SOC 2 Type II; iSnap does not send to groups, has no MCP server and says it does not claim SOC 2.

Best for

Developers and CRM platforms in the US that want iPhone-backed iMessage lines for one-to-one conversations, especially teams that already own iPhones.
