Will your npm dependency work in your target runtime?

RuntimeReady inspects public npm packages for potential compatibility issues across Browser, Node.js, Bun, Deno, Cloudflare Workers, Vercel Edge, and Vite SSR.

• Explore a runtime compatibility matrix.
• Inspect findings with source snippets and dependency paths.
• Read suggested next steps.
• Compare two or three packages for your target runtime.
• Share saved reports without requiring signup.

RuntimeReady uses static analysis—it never executes package code. Results highlight detected issues and uncertainty within scan limits, rather than guaranteeing compatibility.

Try a dependency you use and share any incorrect or unexpected findings.
