Adding AWS S3 to your Supermaven app? Let us review it.
Expert review for AWS S3 integrations built with Supermaven. We fix Supermaven-generated AWS S3 code for security, error handling & production readiness. From $19.
Common Supermaven issues affecting integrations
Fast completions accepted without review introduce subtle type errors
Supermaven's speed is its core advantage, but it encourages accepting completions quickly. TypeScript type errors, incorrect function signatures, and wrong argument orders frequently slip through when developers tab-accept completions at high speed.
Security-sensitive code patterns completed without security review
In security-critical code paths like authentication, token validation, and database queries, Supermaven's completions can introduce subtle vulnerabilities — such as completing a SQL query without parameterization or missing a signature verification step.
Existing codebase anti-patterns replicated across new files at high velocity
Supermaven learns from your codebase, which means bad patterns — deprecated APIs, insecure functions, or architectural mistakes — get propagated to new code rapidly due to how quickly completions are accepted.
AWS S3 issues we find in Supermaven apps
S3 bucket configured with public read/write access
AI-generated code sets the bucket ACL to public-read-write or uses a bucket policy that grants s3:* to everyone, exposing all files and allowing arbitrary uploads.
AWS credentials hardcoded or in client-side code
Generated code includes AWS access key ID and secret access key directly in source files or client-side environment variables instead of using IAM roles or presigned URLs.
File uploads sent through the server instead of presigned URLs
AI tools route all file uploads through your server, creating a bandwidth bottleneck and unnecessary cost, instead of using S3 presigned URLs for direct browser-to-S3 uploads.

Frequently asked questions
Can you review my Supermaven-built AWS S3 integration?
Yes. We regularly audit AWS S3 integrations in Supermaven-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What AWS S3 issues does Supermaven typically create?
Common issues in Supermaven-generated AWS S3 code include: s3 bucket configured with public read/write access, aws credentials hardcoded or in client-side code, file uploads sent through the server instead of presigned urls. We fix all of these in our code review.
How much does it cost to fix my AWS S3 integration?
Start with our code audit ($19) to get a complete list of AWS S3 issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What AWS S3 best practices does Supermaven typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for AWS S3. Our review checks all of these and provides specific fixes.
