Sourcegraph Cody + Chrome Extension

Built a chrome extension with Sourcegraph Cody?
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 Sourcegraph Cody apps

Building a chrome extension with Sourcegraph Cody 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 Sourcegraph Cody 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 Sourcegraph Cody issues we fix

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

highCode Quality

Suggestions based on deprecated or low-quality code patterns found in the existing codebase

Cody's suggestions are grounded in your actual codebase, which means if the codebase contains outdated patterns, deprecated library usage, or known-bad code, Cody will suggest those same patterns in new code — amplifying technical debt.

highSecurity

Cross-repo context can leak patterns from one team's code into another team's service

In large organizations where Cody indexes multiple repositories, suggestions can carry patterns from one team's codebase into another, introducing unfamiliar dependencies, different error handling conventions, or architectural approaches that do not belong in the target service.

mediumSecurity

Security vulnerabilities in existing code recommended as reference implementations

If the indexed codebase contains known security issues that have not yet been patched — unparameterized queries, missing auth checks, insecure deserialization — Cody may suggest these patterns as examples when generating similar code.

mediumPerformance

Performance anti-patterns replicated from existing high-traffic code paths

When Cody finds existing code as a reference for a new feature, it may replicate performance issues — N+1 queries, missing indexes, blocking synchronous calls — that are accepted in the existing code but will be problematic at the scale of the new feature.

Frequently asked questions

Can I build a chrome extension with Sourcegraph Cody?

Sourcegraph Cody 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 Sourcegraph Cody leave in chrome extensions?

Common issues include: suggestions based on deprecated or low-quality code patterns found in the existing codebase, cross-repo context can leak patterns from one team's code into another team's service, security vulnerabilities in existing code recommended as reference implementations. For a chrome extension specifically, these issues are compounded by the need for manifest v3 compliance.

How do I make my Sourcegraph Cody chrome extension production-ready?

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