Chrome Extension Development Company — One of the Few That Specializes

Chrome extensions have unique constraints — Manifest V3 service workers, Chrome Web Store policies, content security policies, cross-origin limitations — that most web developers don't encounter in normal projects. Getting these wrong means your extension gets rejected by the Chrome Web Store or behaves unreliably. We've shipped 30+ Chrome extensions and know every edge case.

Yes, all new extensions we build use Manifest V3, which is now required by Google. This means service workers instead of background pages, Declarative Net Request for network modifications, and strict content security policies. We handle all MV3 migration work if you have an existing MV2 extension.

Yes. CRM integration is one of our most common Chrome extension use cases. We integrate with Salesforce, HubSpot, Pipedrive, Outreach, Salesloft, and most CRMs that have a REST API. We handle OAuth authentication, data sync, and real-time CRM updates from within the extension.

Most successful B2B Chrome extensions use a per-seat SaaS model ($10–30/user/month) with a freemium tier for acquisition. We can build the full subscription infrastructure — Stripe billing, license key validation, usage limits, and team management — as part of the extension project.

A focused extension (one primary use case, 3–4 core features) takes 4–6 weeks. A complex extension with AI features, CRM integrations, and a side panel takes 8–12 weeks. Chrome Web Store review takes 1–3 business days after submission.

Chrome extension projects at Zenkoders start at $8,000 for a simple utility extension and range up to $60,000 for a complex B2B tool with AI features, multiple CRM integrations, and a full subscription billing system. We provide fixed-price quotes.
