CodeScene
CodeScene measures code with CodeHealth, a validated metric predicting defects and delivery performance. It states the average enterprise codebase scores 5.15 out of 10 while AI needs 9.5 to work reliably, and offers an MCP server, automated reviews and IDE feedback. Operated by CodeScene AB.
- Turns technical debt into a number that survives a roadmap conversation
- Prioritising by change frequency avoids refactoring code nobody touches
- Connecting code health to AI reliability is the most useful reframing of legacy code recently
- The MCP server puts the metric where behaviour actually changes
- The 9.5 threshold is a vendor position, not settled fact
- A single score discards architecture, which is often the real problem
- Test quality is invisible to it — coverage is measurable and usefulness is not
Jomatter
Jomatter is a free, no-sign-up set of 15 browser-based HTML, CSS and JavaScript utilities: formatters, minifiers, a markup checker, CSS gradient, shadow and flexbox playgrounds, and sandboxed HTML and JavaScript playgrounds. It is a developer utility, not an AI tool.
- Free with no account or install
- Visual CSS playgrounds are genuinely quick
- Tool code shows no network requests
- Playgrounds run in a sandboxed frame
- Not an AI tool despite the directory listing
- Minifiers are lighter than build tools
- No privacy policy or named operator
