Chrome Extension MVP Development: Ship Your Extension to the Chrome Web Store

Manifest V3 extensions with accounts, payments, sync and AI features, published for you. Fixed price from $1,500, live in 1–5 weeks.

Codersarts builds Chrome extension MVPs for founders, SaaS companies and teams who want to reach users inside the browser. We build Manifest V3 extensions with popups, side panels, content scripts and background service workers, and connect them to a backend for accounts, sync and analytics. SaaS extensions add login, Stripe subscriptions and licence checks, and AI extensions add LLM features such as summarizing pages, drafting replies, extracting data or a side-panel assistant. Pricing is fixed: $1,500–$4,000 for a utility extension (1–2 weeks), $5,000–$10,000 for a SaaS extension with auth, payments and a backend (3–5 weeks), and $6,000–$12,000 for an AI extension (3–5 weeks). We handle Chrome Web Store listing, privacy disclosures and review, design for minimal permissions so reviews pass and users trust the install, can port to Edge and Firefox, and deliver full source code and IP.

We build Chrome extension MVPs, from single-purpose utilities to full SaaS extensions with login, payments, a backend and AI features, and publish them to the Chrome Web Store. Fixed price from $1,500, delivered in 1–5 weeks with full IP transfer.

Yes. Every extension is built on Manifest V3, the current Chrome standard, with service workers instead of background pages.
