Rotwise
About Rotwise
Rotwise analyzes codebases to identify technical debt such as hardcoded secrets, SQL injection risks, swallowed exceptions, N+1 queries, and missing tests. It ranks findings by severity and presents them with suggested fixes. The tool connects via a GitHub app, performs read-only scans, and generates small pull requests containing the proposed fixes. Each pull request is reviewed by the user before merging, allowing incremental improvements without disrupting the main branch. The debt score updates automatically after each merge, providing a measurable indicator of codebase health. Supported languages include Ruby, JavaScript, TypeScript, Python, Go, Rust, and PHP.

Frequently asked questions about Rotwise
What does Rotwise do?
Rotwise analyzes codebases to identify technical debt such as hardcoded secrets, SQL injection risks, swallowed exceptions, N+1 queries, and missing tests. It ranks findings by severity and presents them with suggested fixes.
Who is Rotwise designed for?
Rotwise is designed for solo founders, small engineering teams, and developers who want to improve their codebase without disrupting the main branch. It suits teams building with Ruby, JavaScript, TypeScript, Python, Go, Rust, or PHP.
How does Rotwise work?
Rotwise connects via a GitHub app to perform read-only scans of the codebase. It generates small pull requests containing proposed fixes, which users review and merge incrementally. The debt score updates automatically after each merge.
Does Rotwise modify my code automatically?
No, Rotwise does not modify your code automatically. It proposes fixes as pull requests, which users must review and approve before merging. Nothing is pushed to the main branch without user consent.
What languages does Rotwise support?
Rotwise supports Ruby, JavaScript, TypeScript, Python, Go, Rust, and PHP. It integrates with GitHub to analyze codebases written in these languages.
How do I get started with Rotwise?
To get started, install the Rotwise GitHub app and initiate a scan. The tool performs a read-only analysis of your codebase and generates a report with findings and suggested fixes.
