Market Opportunity
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.
Key competitors include Sentry, Datadog (APM & RUM), Rollbar, Bugsnag, Chrome DevTools / custom logging (workaround).
