Blueprint Softphone

Professional softphone with background listening and click-to-dial. Built on Twilio.

Not a sidebar. Blueprint runs silently in Chrome, pops open on incoming calls, and closes when you're done. Powered by your Twilio account. BLUEPRINT SOFTPHONE Is a professional business phone system for Google Chrome — built on your Twilio account, with a UX architecture that's fundamentally different from every other softphone extension on the market. IT DOESN'T LIVE IN YOUR SIDEBAR Every other browser-based softphone works the same way: a sidebar panel bolted onto your browser, permanently consuming screen real estate on every tab you open. Close that sidebar, and you stop receiving calls. Blueprint Softphone works differently. It runs as a hidden background listener. As long as Chrome is open, your line is active — no panel to keep open, no tab to pin, nothing on your screen. When a call comes in, the phone UI opens automatically, audio rings, and you answer. When you're done, minimize it to the taskbar or close it completely. Your line stays active either way. Your screen stays yours. CHROME EXTENSION + WEB APP + MOBILE — ONE PLATFORM The Chrome extension is where most users start. But Blueprint is a platform, not just an extension. - CHROME EXTENSION: The primary experience. Popup window, always-on background listener, click-to-dial, full calling and SMS. Available now. - WEB APP: A full-screen dedicated softphone at app.blueprintsoftphone.com. Same Twilio account, same numbers, no extension required. Available now. - IPHONE & ANDROID: Native mobile apps are actively in development. Pro subscribers get access when they launch — no additional cost, no separate subscription. Join the waitlist at blueprintsoftphone.com. This matters for the Pro upgrade decision: at $4.99/month, you're not just buying unlimited phone numbers — you're buying into a cross-platform business phone system that follows you from your browser to your phone. YOUR TWILIO ACCOUNT. OUR INTERFACE. ZERO MARKUP. Blueprint Softphone is a pass-through interface — you bring your Twilio account, we provide the phone system. Your calls are billed directly from Twilio to you at their published wholesale rates. Blueprint adds nothing on top. WHAT DOES IT ACTUALLY COST? - Twilio Phone number: $1.15/month - Outbound calls: $0.014/min — less than a penny and a half per minute - Inbound calls: $0.0085/min — under a penny per minute - Most Blueprint users: $2–5/month total in Twilio usage Competitors like JustCall charge $19/seat/month for "unlimited calling." That sounds simple — until you do the math. At Twilio's rates, you'd need to make over 1,200 minutes of outbound calls every month, on every single line, before your total Twilio usage even approaches what JustCall charges for one seat. That's 20+ hours of active calling, per line, per month. If you're that busy — Twilio's usage-based model still wins, because you're not subsidizing idle lines across your organization. You pay for what you use at wholesale, with nothing added on top. Verify the rates yourself at twilio.com/en-us/voice/pricing. SECURITY IS THE ARCHITECTURE, NOT A POLICY Your Twilio credentials authenticate directly to Twilio's API from your browser. They never pass through Blueprint's servers — because Blueprint's servers never see them. - We can't be hacked for your credentials. We don't have them. - We can't spend your money — Blueprint has zero billing permissions on your Twilio account. - Your call audio goes to Twilio, not us — WebRTC/SRTP encrypted, end-to-end. - Our code is open to inspection — auditable anytime via chrome://extensions. - If Blueprint disappeared tomorrow, your Twilio account would be completely unaffected. KEY FEATURES - POPUP WINDOW UI: Not a sidebar. A clean, moveable phone window. - ALWAYS-ON BACKGROUND LISTENER: Your line stays active whenever Chrome is running. - AUTO-OPENS ON INCOMING CALLS: UI surfaces automatically, audio rings, desktop notification fires. - VOICE CALLING: Make and receive calls on Twilio's Voice SDK. Hold, mute, DTMF keypad. - SMS MESSAGING: Threaded conversations from your business numbers.
