Base44 + Chrome Extension

Built a chrome extension with Base44?
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 Base44 apps

Building a chrome extension with Base44 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 Base44 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 Base44 issues we fix

Beyond chrome extension-specific issues, these are Base44 patterns we commonly fix.

highDeployment

Platform lock-in makes it expensive to migrate to self-hosted infrastructure

Base44 applications run on Base44's infrastructure with proprietary abstractions. If you need to migrate to AWS, Vercel, or a custom backend, you must substantially rewrite the application since the generated code is tightly coupled to Base44's runtime.

highSecurity

Auto-generated backend API lacks input validation and allows malformed data into the database

Base44's generated REST API endpoints often accept and persist any data that matches the field type without business-rule validation — missing required fields, out-of-range values, or invalid relationships are stored without error.

mediumCode Quality

Limited customization of business logic after the initial app generation

Once Base44 generates the application structure, adding custom business logic that deviates from the generated patterns — complex workflows, conditional processing, third-party integrations — requires working around the platform rather than with it.

mediumBugs

Database schema changes after initial generation are difficult and risk data loss

Modifying the generated database schema after data has been collected — adding columns, changing relationships, renaming tables — is fragile in Base44 and may require manual data migration that the platform does not assist with.

Frequently asked questions

Can I build a chrome extension with Base44?

Base44 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 Base44 leave in chrome extensions?

Common issues include: platform lock-in makes it expensive to migrate to self-hosted infrastructure, auto-generated backend api lacks input validation and allows malformed data into the database, limited customization of business logic after the initial app generation. For a chrome extension specifically, these issues are compounded by the need for manifest v3 compliance.

How do I make my Base44 chrome extension production-ready?

Start with our code audit ($19) to get a clear picture of what needs fixing. For most Base44-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 Base44-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.
