Project Blue, from Project Blue Services LLC in the United States, sends iMessage with SMS fallback from dedicated phone lines it runs for you. It is sold mainly to sales teams and agencies as a channel inside GoHighLevel, HubSpot and Close CRM, and it also offers a REST API and a remote MCP server for developers. The company says it has served paying customers since early 2024.
The pricing page lists $166 a month per line billed annually ($1,998 a year, setup fee waived), or $199 a month per line on a 12-month plan billed monthly. Enterprise pricing is custom. Texting is unlimited under fair use. A free trial uses a shared line that can only reach verified numbers.
Both sell iMessage on managed lines with SMS fallback, flat pricing and an MCP server. Linq lists a free Hobby tier and Pro from $260 a month, and documents polls, read receipts, signed webhooks and SDKs for TypeScript, Python and Go. Project Blue documents FaceTime Audio calling and a full dialer, which Linq's API does not offer. Its webhooks have no retries or signatures documented, and its only SDK is a browser calling SDK.
Sales teams and agencies that want iMessage, SMS and calling inside GoHighLevel, HubSpot or Close, with an API for custom tools.
