Is a browser API breaking change alert service worth paying for?

Yes, for teams running production JavaScript apps, it can be worth paying for after a single avoided incident. The value is not the browser news itself; it is the time saved diagnosing silent breakage and the support pain avoided.

How do you detect browser API changes in a JavaScript codebase?

The practical approach is AST analysis plus a curated change database. You scan the code for patterns that use affected browser APIs, then compare those matches against known behavior changes from Chromium, Gecko, and WebKit.

What is the best MVP for browser compatibility monitoring for small teams?

The best MVP is a GitHub-integrated scanner for private repos with alerts on a narrow set of high-risk APIs. It should flag exact files, explain the browser change in plain English, and suggest a fix or mitigation.

How is this different from MDN or caniuse?

MDN and caniuse are reference tools, not proactive code-aware alert systems. They help once you know what to look for, while this product is supposed to warn you before a browser update turns into a production bug.

Which developers would buy a browser changelog monitoring tool?

Small SaaS teams, indie app developers, agencies, and internal tools teams are the best early buyers. They ship enough frontend code to feel real breakage, but usually do not have dedicated browser compatibility specialists.

What could kill this startup idea?

Poor alert quality is the biggest threat. If the product produces noisy warnings or misses obvious breakages, developers will treat it like another static analysis tool they disable after one sprint.
