Chrome extension
Nimra - Click to Call
A phone line that lives in your browser — call and text from any webpage, without switching apps or picking up your phone.
Summary
A Chrome extension that turns your browser into a full phone line. Click any number on any page to call. Inbound calls ring directly in the browser. SMS with full threading, real-time updates. Billing built in. Works while you browse.

What Was Built
Overview
Click any number on any page to call. Inbound calls ring in the extension. SMS with full threading. The architecture keeps WebRTC alive in the background — call state survives popup close, no dropped connections.
Status
Live
Type
Browser Extension
Platform
Chrome
Problem
WebRTC state dies when a Chrome popup closes. Inbound calls silently fail the moment the user navigates away.
Approach
An offscreen document holds the Telnyx listener permanently in the background. A dedicated call window runs the WebRTC session independently of the popup lifecycle. Supabase Realtime delivers SMS without polling.
Outcome
Calls stay alive with the popup closed. Full phone line — calls, SMS, contacts, history — inside an extension.
