Respect framework pageExtensions in route linting — auto-detect and enforce

Many web teams and individual maintainers run into noisy or incorrect route-linting results when frameworks allow configurable pageExtensions (for example custom .page.tsx, .route.js, etc. instead of defaults), causing CI failures, broken editor feedback, and extra onboarding friction in codebases and monorepos. This problem affects front-end engineers, platform teams, and devtools maintainers across the estimated 24 million active web developers who increasingly depend on low-noise static analysis to move quality left. You could build a route-linting engine and IDE/CI integrations that first auto-detect a project’s pageExtensions and routing conventions (by reading framework configs, scanning file patterns, and using heuristics or lightweight ML), then synthesize and enforce project-specific rules with safe auto-fixes and a clear override policy. Integrations would include ESLint plugins, VS Code diagnostics, and a CI runner; optional LLM-assisted rule synthesis could propose rules for atypical setups. The market conditions make this attractive now: frameworks are trending toward pluggable conventions, teams demand smarter shift-left tools, and with a $2.4B TAM (24M devs × $100/year) and a market score of 92/100 there’s room to capture value despite a revenue potential scored at 72/100. To stand out you must minimize false positives and friction—deliver near-zero-noise defaults, fast project auto-discovery, and seamless editor/CI UX—then layer an open-source core with paid enterprise features (policy dashboards, multi-repo scans). Expect medium competition from existing linter ecosystems, and be candid about challenges: maintaining accuracy across framework versions, handling custom build pipelines, and achieving adoption over established ESLint rules; these are solvable but require investment in test coverage, real-world corpus analysis, and solid onboarding.
