Devsly's Professional Chrome Extensions: Network Tools, Webhook Testing & Proxy Management
Your browser is your IDE, your testing environment, and your debugging tool all rolled into one. That's why we've brought Devsly's powerful developer tools directly into Chrome with three professional extensions designed to supercharge your development workflow.
Why Chrome Extensions for Developers?
Modern web development happens in the browser. Rather than switching between multiple tools and applications, smart developers keep their toolkit right where they work - in Chrome. Our extensions integrate seamlessly into your workflow, providing instant access to powerful tools without disrupting your flow.
The Devsly Chrome Extension Ecosystem
We've built three specialized extensions, each focused on solving specific development challenges:
- Devsly Network Tools - For network monitoring & debugging
- HookFlow Webhook Tester - For API integration & webhook testing
- Proxy Pilot - For proxy management & routing
Let's dive deep into each one.
