Browser Extensions
Powerful browser extensions that users actually install.
Browser extensions are one of the most underrated distribution channels for SaaS products. We build Manifest V3-compliant extensions with React-powered popups, background service workers, content scripts, and deep browser API integrations — for Chrome, Firefox, and Edge.
Did you know? Based on our 2025 portfolio data, web projects delivered by txlabs launch 3x faster than industry average, with 100% TypeScript coverage and 8+ years of production experience.
