Incorrectly instrumented rejected Promises (e.g., storing reason on the wrong field) make real errors vanish and debugging extremely painful. Add a lightweight runtime guard that throws a helpful error with a usable callstack when the rejection reason is missing, surfacing the true cause.
Target Audience
Engineering teams (frontend, SRE, platform) at companies building React-based web apps who need reliable production debugging for uncaught/rejected Promises and value low-friction instrumentation.

Make Promise rejection instrumentation errors obvious: runtime guard surfaces real reasons targets a $31.2B = 26M developers x $1,200 avg annual dev-tools & observability spend total addressable market with medium saturation and a year-over-year growth rate of 12-18% annual growth for developer tooling & observability markets, with higher growth in front-end observability niches.
Key trends driving demand: Client-side observability -- rising investment in frontend error monitoring and performance tooling increases demand for low-noise, accurate signals; SDK complexity -- more third-party SDKs and instrumentations on the client raise the chance of developer-applied instrumentation mistakes; AI-assisted diagnostics -- advances in lightweight ML make grouping and surfacing root causes from stack traces much faster and more reliable.
