Executive Summary

Debugging React UIs is slow because engineers must trace rendered components in the browser back to exact source lines across bundlers, source maps, and minified code; this pain falls on frontend engineers and teams (est. ~500K teams) who spend disproportionate time triaging UI regressions. The core friction—mapping runtime React component instances to original lines in a local editor—is technically tricky because of build pipelines and varying source-map quality. Build a browser extension plus local agent that, with one click on a running React component, opens the developer’s IDE at the exact source file and line using React Fiber IDs, source maps, and the editor protocol, with a fallback UI that surfaces likely locations when mappings are ambiguous. Distribute it as open-source with a frictionless free tier and a paid enterprise offering (auditing, team sync, remote mapping resolution) to support monetization. The market timing is favorable: React remains dominant and teams are moving to in-browser workflows that expect tight editor integration, giving this idea a Market Score of 88/100 and Revenue Potential of 82/100. With a $1.5B TAM (500K teams × $3K ACV) and strong product-led distribution dynamics, you can drive rapid adoption via OSS virality plus enterprise upsells. To compete, focus on zero-config, local-first privacy (no source uploads), robust bundler/source-map heuristics, deep React Fiber integration, and an open-source free tier that accelerates adoption while reserving team and compliance features for paid accounts.

Market Opportunity

Jump from running React components to exact source lines in one click targets a $1.5B = 500K engineering teams × $3K ACV (developer productivity + devtools budget per team) total addressable market with medium saturation and a year-over-year growth rate of 10-15% annually — developer tools and dev productivity spend is growing as organizations invest in developer velocity (source: Stack Overflow developer trends, GitHub State of the Octoverse).

Key trends driving demand: Framework consolidation — React remains dominant for large numbers of front-end teams, increasing the addressable pool for React-specific tools.; Tooling shift to in-browser workflows — teams expect low-friction browser integrations that connect to local IDEs, creating demand for runtime-to-source links.; Product-led OSS distribution — developer tools that are open-source or have a frictionless free tier achieve fast adoption and community-driven virality..

Key competitors include React Developer Tools, Sourcegraph, OpenReplay.
