Supermaven + Chrome Extension

Built a chrome extension with Supermaven?
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 Supermaven apps

Building a chrome extension with Supermaven 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 Supermaven chrome extension

Manifest V3 compliance — service workers, permissions, CSP
Permission minimization — only requesting what's needed
Content security — no eval(), no inline scripts, no remote code
Data handling — privacy policy, secure storage, no unnecessary collection
Error handling — graceful failures, no silent errors
Performance — efficient background processing, minimal memory usage
Chrome Web Store compliance — metadata, screenshots, descriptions

Common Supermaven issues we fix

Beyond chrome extension-specific issues, these are Supermaven patterns we commonly fix.

highBugs

Fast completions accepted without review introduce subtle type errors

Supermaven's speed is its core advantage, but it encourages accepting completions quickly. TypeScript type errors, incorrect function signatures, and wrong argument orders frequently slip through when developers tab-accept completions at high speed.

highSecurity

Security-sensitive code patterns completed without security review

In security-critical code paths like authentication, token validation, and database queries, Supermaven's completions can introduce subtle vulnerabilities — such as completing a SQL query without parameterization or missing a signature verification step.

mediumCode Quality

Existing codebase anti-patterns replicated across new files at high velocity

Supermaven learns from your codebase, which means bad patterns — deprecated APIs, insecure functions, or architectural mistakes — get propagated to new code rapidly due to how quickly completions are accepted.

mediumTesting

Test completions mirror happy-path structure without edge case coverage

When completing test code, Supermaven tends to replicate the structure of surrounding tests, which often means test completions also omit edge cases, error paths, and boundary conditions that the surrounding tests miss.

Frequently asked questions

Can I build a chrome extension with Supermaven?

Supermaven 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 Supermaven leave in chrome extensions?

Common issues include: fast completions accepted without review introduce subtle type errors, security-sensitive code patterns completed without security review, existing codebase anti-patterns replicated across new files at high velocity. For a chrome extension specifically, these issues are compounded by the need for manifest v3 compliance.

How do I make my Supermaven chrome extension production-ready?

Start with our code audit ($19) to get a clear picture of what needs fixing. For most Supermaven-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 Supermaven-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.
