Executive Summary

Frontend teams and build engineers waste hours every week chasing ambiguous bundle treemaps that hint at regressions but don’t tell you which changed files or imports actually caused a size or performance delta. The problem is acute for modern apps using code-splitting, dozens of third-party packages and rapid PR-driven workflows, where a single commit can ripple across many bundles and create noisy visualizations that are hard to triage in the 10–30 minutes available during code review. You could build a small, fast layer that lets users toggle a treemap into a searchable, filterable diff table showing file- and import-level deltas, sortable by bytes, runtime impact, and ownership, with source-map resolution, commit/PR links, CI annotations and optional correlations to runtime performance traces. Delivering this as CI-friendly artifacts and a lightweight browser UI that integrates with webpack/esbuild/rollup and GitHub/GitLab would give developers an actionable list of 5–10 highest-impact deltas instead of a vague visual blob. The timing is favorable: frontend complexity, the shift-left push for PR-level feedback and growing expectations to connect build metrics with runtime observability create clear demand, and the TAM you’ve estimated—roughly $6.0B (2M teams × $3K ACV)—means even modest penetration yields meaningful revenue potential. This idea can stand out by focusing on precision and workflow integration rather than prettier treemaps—source-map-aware diffs, low-noise heuristics and PR-native annotations are defensible differentiators—but the hard parts are real: reliable mapping across build toolchains, avoiding false positives, and getting the first canonical integrations into popular CI and repo hosts. If you can solve those engineering challenges and demonstrate a 2×–5× speedup in triage time for early customers, the product can win a sustainable niche despite medium competition.

Executive Summary

Market Opportunity

Compare build deltas quickly — toggle treemap to a searchable diff table targets a $6.0B = 2M software teams x $3K ACV total addressable market with medium saturation and a year-over-year growth rate of 12% (developer tooling & observability segment).

Key trends driving demand: Frontend complexity -- more bundles, code-splitting and dependencies increase surface area for regressions and make granular diffing valuable.; Shift-left CI feedback -- teams demand actionable build feedback in PRs, making table diffs a natural fit for fast remediation.; Observability convergence -- combining build metrics with runtime performance data raises demand for precise, file-level diffs to connect cause and effect..

Key competitors include webpack-bundle-analyzer, source-map-explorer, bundlewatch, Bundlephobia, Calibre (adjacent competitor — web performance monitoring).
