GitHub
Everything on this hub is open source. One repo, every tool. Clone it, self-host it, break it, improve it, send a PR.
The complete open source hub: Next.js app, 100-tool catalog, interactive calculators, SEO + EEAT infrastructure, and the mainstreetwealth.ai cross-link layer.
Clone and run
Everything on this hub is a Next.js 15 app. Clone, install, and run.

Node 20+ required. Then open http://localhost:3000.

A single Next.js app. Each tool lives in app/<slug>, with shared logic in components/ and lib/.
Next.js App Router pages: hub, directory, every tool page.
Shared UI and calculator components (EBITDA, SDE, add-backs, rollover, net proceeds, scorecards).
Tool catalog, author profiles, schema.org helpers, and mainstreet.ai cross-link map.
Logo and static assets.
Agent hooks and project automation.
