Every feature in one app

Every feature optz shares with Next.js, in one small app: streaming and _loading, Server Actions (also without JavaScript), ISR and on-demand revalidation, dynamicParams, draft mode, optional catch-alls, parallel and intercepting routes, i18n (en/fr), Open Graph images, sitemap, robots and manifest, <Image>, self-hosted fonts, <Script>, prerendered and cookie-setting API routes, and an error page, all under a strict CSP.

bun run build && bun run start        # http://127.0.0.1:3002
node e2e.cjs http://127.0.0.1:3002    # 22 browser checks
bun run dev  &  node hmr.cjs          # dev server: Fast Refresh, CSS swap, in-place updates (6 checks)

The same suite passes against optz build --compile (dist/server) and optz build --target edge (dist/edge/worker.js in Cloudflare's workerd), with UNOPTIMIZED=1 where no image library is available.
