/apps/quicktool
A color contrast checker
Pick two colors, see whether they pass WCAG accessibility ratios. One HTML file, no build step, no bridge calls, drop in a saved Claude artifact and ship.

- zero-build

Live proof
Not a mockup. Not a roadmap. Not a video pretending to be a product. These apps are running on designsetgo.dev through the same DSGo Apps runtime you install on your site, and the source for each is a public repo you can fork.
Try the installed apps
The three-app set intentionally spans the launch claims: a saved artifact, a permissioned WordPress action, and a connected commerce app.

/apps/contact
A polished form on your site that emails you when visitors reach out. The app never holds an SMTP password, WordPress's built-in mailer handles delivery.
/apps/shop
A polished product grid, cart, and checkout that lives alongside your existing WooCommerce store. No theme tweaks. If the app breaks, your site is fine.
Proof checklist
Each example is deliberately small enough to audit: manifest, app source, release bundle, and live route all line up.
Zero-build artifact
One HTML file, no bridge permissions, strict iframe sandbox.
examples/quicktool/dsgo-app.json Permissioned WordPress action
Can send only to the site admin through wp_mail. The iframe never holds SMTP credentials.
examples/contact/dsgo-app.json Connected commerce app
Reads WooCommerce products and cart through declared commerce and abilities permissions.
examples/shop/dsgo-app.json Common objections
Launch visitors will ask what happens after the first neat demo. The answer is visible here: permissions, source, isolated routes, and reusable bundles.
Now check the broader slate
The examples page includes the full app lineup: member portal, block renderer, inline pricing page, recipe ranker, Stripe proxy, and AI companion preview.
