Built a chrome extension with Fine.dev?
We'll make it production-ready.
Chrome extensions have unique security considerations — they run in users' browsers with elevated permissions, can access browsing data, and must pass Chrome Web Store review. AI tools can scaffold an extension quickly, but the security requirements, Manifest V3 compliance, and store submission guidelines need careful attention.
Chrome Extension challenges in Fine.dev apps
Building a chrome extension with Fine.dev is a great start — but these challenges need attention before launch.
Manifest V3 compliance
Chrome is migrating to Manifest V3, which changes how extensions work — service workers instead of background pages, restricted remote code execution, and new permission models. AI tools sometimes generate Manifest V2 code that won't be accepted.
Permission minimization
Chrome Web Store reviews extensions for excessive permissions. Request only the permissions you actually need. AI tools often request broad permissions ('tabs', 'storage', 'activeTab') when narrower permissions would suffice.
Content Security Policy
Extensions must comply with strict CSP rules. No inline scripts, no eval(), no remote code loading. AI-generated code sometimes violates these rules, causing the extension to fail silently.
Data privacy
Extensions that access browsing data must have a privacy policy, explain what data is collected, and handle it securely. Chrome Web Store requires this disclosure for approval.
Cross-browser compatibility
If you want to publish on Firefox, Safari, and Edge too, your extension needs to handle API differences between browsers. AI tools usually target Chrome only.
What we check in your Fine.dev chrome extension
Common Fine.dev issues we fix
Beyond chrome extension-specific issues, these are Fine.dev patterns we commonly fix.
Spec interpretation may differ significantly from intent
Fine.dev builds exactly what the specification says, not what you meant. Ambiguous specs lead to technically correct implementations that miss the actual product requirement.
Cross-file changes may miss security implications
When Fine.dev generates features spanning multiple files, security-sensitive changes — new endpoints, auth checks, data access patterns — are spread across the PR without a consolidated security review surface.
Generated tests may not cover real-world edge cases
Fine.dev writes tests for the happy path and obvious failure cases from the spec. Edge cases not explicitly mentioned — concurrent requests, null inputs, rate limits — are frequently untested.
Cross-file changes introduce inconsistencies
Large implementations touching many files accumulate subtle inconsistencies — type assumptions that don't hold across modules, different error handling patterns in different files.

Frequently asked questions
Can I build a chrome extension with Fine.dev?
Fine.dev is a great starting point for a chrome extension. It handles the initial scaffolding well, but chrome extensions have specific requirements — manifest v3 compliance and permission minimization — that need professional attention before launch.
What issues does Fine.dev leave in chrome extensions?
Common issues include: spec interpretation may differ significantly from intent, cross-file changes may miss security implications, generated tests may not cover real-world edge cases. For a chrome extension specifically, these issues are compounded by the need for manifest v3 compliance.
How do I make my Fine.dev chrome extension production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most Fine.dev-built chrome extensions, the critical path is: security review, then fixing core flow reliability, then deployment. We provide a fixed quote after the audit.
How much does it cost to fix a Fine.dev-built chrome extension?
Our code audit is $19 and gives you a complete report of issues. Fixes start at $199 with our Fix & Ship plan. For larger chrome extension projects, we provide a custom fixed quote after the audit — no hourly billing.
