Building a chrome extension with Rust? Let us review it.
Expert code review for chrome extensions built with Rust. We fix Rust-specific security gaps, optimize performance, and handle deployment. From $19.
Common Rust issues we find
Real problems from Rust codebases we've reviewed.
Excessive .clone() usage
AI tools clone data everywhere to satisfy the borrow checker instead of using references, lifetimes, or Cow — defeating Rust's zero-cost abstraction goals.
Unnecessary unsafe blocks
Using unsafe to bypass compiler checks rather than restructuring code to work within safe Rust, introducing memory safety vulnerabilities.
Improper error handling with unwrap()
Calling .unwrap() and .expect() on Result and Option types instead of proper error propagation with ? operator, causing panics in production.
Blocking in async contexts
Using std::thread::sleep, synchronous I/O, or blocking mutex locks inside async functions, starving the Tokio runtime of worker threads.
Chrome Extension challenges to solve
Key chrome extension concerns that AI-generated code often misses.
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.
What we check
Key areas we review for Rust chrome extension projects.
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

Frequently asked questions
Can you review a chrome extension built with Rust?
Yes. We regularly audit Rust chrome extension projects and understand the specific patterns and pitfalls of this combination. Our review covers security, performance, and deployment readiness.
What issues do you find in Rust chrome extensions?
Common issues include excessive .clone() usage and unnecessary unsafe blocks on the Rust side, combined with chrome extension-specific concerns like manifest v3 compliance and permission minimization. We check for all of these and more.
How do I make my Rust chrome extension production-ready?
Start with our code audit ($19) to get a prioritized list of issues. For Rust chrome extension projects, the typical path is: fix security gaps, address chrome extension-specific requirements, optimize Rust performance, then configure deployment. We provide a fixed quote after the audit.
How long does it take to audit a Rust chrome extension?
Our code audit delivers a full report within 24 hours. For Rust chrome extension projects, we check security, architecture, performance, and deployment readiness across all Rust-specific patterns. Fixes are scoped separately with a fixed quote.
