Expert Remix Code Review for AI-Built Apps
Remix is a full-stack React framework focused on web standards and progressive enhancement. AI tools generate Remix apps with improper loader/action patterns, missing error boundaries, and inadequate form validation.
Common Remix issues we find
Real problems from Remix codebases we've reviewed.
Unprotected action functions
Remix action functions that modify data without verifying user authentication or authorization, allowing anyone to submit forms programmatically.
Missing error boundaries
No ErrorBoundary or CatchBoundary exports in routes, causing unhandled loader/action errors to crash the entire page.
Loader data over-fetching
Loaders returning entire database records to the client instead of selecting only the fields needed for rendering, leaking sensitive data.
Missing server-side form validation
Actions that trust client-side validation without re-validating on the server, allowing malformed or malicious data submissions.
Waterfall data loading
Nested routes with sequential loader dependencies instead of parallel loading, causing slow page transitions.
Remix production checklist
Key checks before deploying your Remix app.
All actions verify authentication and authorization
ErrorBoundary exported in every route module
Loaders return only necessary fields (no full records)
Server-side validation on all action inputs
Parallel data loading where possible (avoid waterfalls)
Proper cache headers on loader responses
CSRF protection on all form actions
Production build optimized and tested
Not sure if your app passes? Our code audit ($19) checks all of these and more.

Frequently asked questions
Is Remix better than Next.js for my app?
Remix excels at form-heavy apps and progressive enhancement. Next.js has a larger ecosystem and more AI tool support. We can evaluate your needs and recommend the right framework.
How do you secure Remix loaders and actions?
We add authentication checks to all actions, validate inputs server-side, sanitize loader data to prevent over-exposure, and implement CSRF protection.
Can you deploy my Remix app?
Yes. We deploy to Vercel, Fly.io, Cloudflare Workers, or traditional Node.js hosts — choosing the platform that best fits your app's needs and budget.
