Market Opportunity
Warn on NaN passed to aria-* attributes — runtime detection & fixes targets a $24.0B = 10M web development teams x $2,400 avg annual dev tooling & accessibility spend total addressable market with medium saturation and a year-over-year growth rate of 12% (developer tools & a11y tooling growth driven by regulation and cloud dev workflows).
Key trends driving demand: Regulatory pressure on accessibility -- governments and litigants demand measurable a11y compliance, increasing spend on tooling.; Framework consolidation around React -- large share of front-end apps means React-targeted tooling finds product-market fit faster.; Shift-left QA & CI automation -- teams prefer dev-time and CI warnings over post-release audits, favoring runtime/CI checks.; AI-assisted code reviews and auto-fixes -- developers increasingly accept machine-suggested fixes, improving adoption for auto-remediations..
