About Browser Developers
Browser Developers is a specialist browser development and advanced software engineering company. Our engineers have spent more than 15 years working inside Chromium and Firefox, delivering 300+ projects for clients worldwide, from custom browsers and production extensions to desktop applications. 18 of those projects are published here as detailed case studies.
Who we are
A specialist engineering team, not a general agency
Browser Developers is a Pakistan-based specialist engineering company, working since 2012. Our engineers work as a remote team and serve clients worldwide, and we operate internationally through a U.S. LLC and business presence.
The team is built around one kind of work: difficult browser and desktop software. Engine-level Chromium and Firefox development, production extensions, desktop applications and the version porting that keeps them current. Most of our engineers have worked on this for years, which is why we have seen the problems your project is about to hit.

What we are specialists in
Three disciplines, one team, all built around the browser.
Custom browsers
Real Chromium and Firefox forks with your features, privacy controls and enterprise policies, delivered as a maintained patch series on top of upstream.
Learn moreBrowser extensions
Production Manifest V3 extensions for Chrome and Chromium browsers, ported to Firefox, Edge and Safari when the same product has to work everywhere.
Learn moreDesktop apps
Electron and Tauri applications for Windows, macOS and Linux, with signed installers, auto-update, native OS integration and production distribution.
Learn moreHow we work
Every project follows the same five steps, and each one ends with something you can review.
Feasibility
We check whether the idea works at the engine or API level and what it will cost to keep.
You get: A written go or no-go with risks and a rough estimate
Architecture
We decide where each change lives: a patch, a flag, an extension or a separate process.
You get: A design note and a milestone plan
Build
We work in short milestones, with each change in a reviewable commit or patch.
You get: Working builds you can run at every milestone
Harden and test
We test on Windows, macOS and Linux, check upgrade paths and fix regressions.
You get: A test report and a release candidate
Release and maintain
We ship signed builds, document the setup and stay available for upstream updates.
You get: Release builds, documentation and a handoff session
Our principles
How our engineers work
The engineering culture behind projects that stay maintainable years after delivery.
Work in the source, not wrappers
If a feature needs a change inside Chromium or Gecko, we make it there. A thin shell around an existing browser cannot deliver engine-level behavior.
Small, reviewable patches
Every change is kept small and documented so your engineers can read it, question it and rebase it. No opaque code drops.
Plan upgrades from day one
Chromium ships new major versions regularly, with security fixes in between. We isolate our changes so version updates are routine work instead of a rewrite.
Recommend the cheaper option when it is enough
Sometimes an extension or a configuration change does the job. We say so, even when it means a smaller project.
Clean handoff
Every project ends with documentation, build instructions and a working session, so your team can run and extend what we deliver.
