About DevGenius.co
A specialized browser development agency. We build custom browsers, extensions, and desktop applications from source — shipped across Windows, macOS, and Linux.
Our Story
DevGenius was built for one reason: browser software is hard, and most agencies can't touch it.
Forking Chromium and keeping it in sync with upstream releases. Building extensions that behave the same across Chrome, Firefox, Brave, and Edge. Shipping Electron and Tauri apps that feel native on three operating systems. Embedding browsers into kiosks, POS systems, and enterprise workflows. These are the problems we solve every day.
Our engineers work inside Chromium and Gecko source code — not just on top of browser APIs. We handle engine-level modifications, feature porting between browser versions, Manifest V3 extension development, and cross-platform desktop builds with Electron and Tauri.
We don't build websites. We don't build mobile apps. We build browser software — custom browsers, extensions, and desktop applications. That's the entire focus, and it's why teams come to us when the work gets technical.
Every project ships production-ready with clean documentation and full knowledge transfer. We don't hand off prototypes and disappear.

What Sets Us Apart
Four things that make DevGenius different from every other dev shop.
Source-level browser engineering
We work inside Chromium, Gecko, and WebKit source code. Engine modifications, feature porting across versions, fork maintenance, and upstream integration. This isn't wrapper development — it's deep systems work at the browser engine level.
Cross-platform from day one
Every browser build, every extension, every desktop app ships on Windows, macOS, and Linux. We build for all platforms from the start with native OS integration where it matters — not as an afterthought.
Full lifecycle partnership
We don't just build and disappear. From initial feasibility analysis through custom builds, QA, upstream version porting, and long-term maintenance — every project includes documentation and knowledge transfer so your team can maintain what we deliver.
Pure browser focus
We're not a general web agency that happens to do some browser work. Browser development, extensions, and desktop applications are the only things we do. Every engineer on the team works in this space full-time. That focus is why we go deeper than generalists can.
Our Promise
What you get on every project.
On-time delivery
We set realistic timelines and hit them. Every milestone scoped, every deadline met.
Production-ready code
No prototypes disguised as deliverables. Every build is tested, optimized, and deployment-ready.
Full documentation
Complete technical documentation, architecture guides, and knowledge transfer included with every project. Your team can maintain and extend everything we build.
Ongoing support
We offer long-term maintenance, upstream version porting, and follow-on engineering. When the next Chromium release drops and your fork needs updating, we're here.
How We Work
The principles behind every project.
Technical depth over breadth
We'd rather be the best at three things than average at thirty. Browser engineering, extensions, and desktop apps — that's the scope, and we go deeper than anyone.
Honest engineering
If something isn't feasible, we'll tell you before you spend money on it. If there's a simpler approach, we'll recommend it even if it means a smaller project. We optimize for long-term trust, not short-term revenue.
Clear communication
Browser engine work is complex. We break it down into clear updates, documented decisions, and regular check-ins. You'll always know what we're building, why, and where it stands.
Remote-first, global delivery
We work with teams worldwide. Async communication, documented processes, and clear handoffs — timezone differences don't slow us down.
