Custom Chrome Extension Development
MV3-native builds with clean architecture, measurable performance, and smooth Chrome Web Store approvals.
Problems we solve
- Unclear MV3 limits (service workers, DNR, offscreen docs)
- Flaky content scripts and messaging
- Rejections due to permissions/privacy
- Slow, unobservable runtime behavior
Our solution
We scope features, design an MV3-native architecture, implement typed, modular code, and ship with tests, telemetry, and publishing assets.
Deliverables
- UX flows & permissions plan
- MV3 architecture (service worker, messaging, storage)
- Feature development with tests
- Performance/observability hooks
- Chrome Web Store listing assets & privacy labels
- Docs + recorded walkthrough
