Databutton + Chrome Extension

Built a chrome extension with Databutton?
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 Databutton apps

Building a chrome extension with Databutton 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 Databutton 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 Databutton issues we fix

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

highSecurity

SQL injection in AI-generated query strings

Databutton's generated FastAPI endpoints sometimes build SQL queries using f-strings or string concatenation with user-supplied parameters, bypassing parameterized query protections entirely.

highSecurity

No authentication on data API endpoints

Data pipeline endpoints are frequently generated without authentication middleware, exposing raw database access and sensitive business metrics to anyone who discovers the API URL.

mediumBugs

Unhandled data type mismatches crashing pipelines

Generated data processing code assumes clean input schemas. When upstream data contains nulls, type changes, or unexpected formats, pipelines throw unhandled exceptions and fail silently.

mediumBugs

Missing pagination on large dataset queries

Data queries load entire tables into memory without limit or offset clauses. With more than a few thousand rows, responses time out and memory usage spikes.

Frequently asked questions

Can I build a chrome extension with Databutton?

Databutton 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 Databutton leave in chrome extensions?

Common issues include: sql injection in ai-generated query strings, no authentication on data api endpoints, unhandled data type mismatches crashing pipelines. For a chrome extension specifically, these issues are compounded by the need for manifest v3 compliance.

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

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