Build a portable front end with explicit behavior.

Static HTML, CSS, and JavaScript are a useful choice when the job belongs in the browser: a small site, a calculation tool, or a compact game. Tell Uvilno the file and route scope, the allowed dependencies, and how each control behaves. Review the rendered result before unlocking its source. Static output keeps deployment straightforward, while forms and any remote data still need a real configured service.

A good fit when the scope is clear.

Developers and creators who prefer a bounded static front end with portable files and clear integration requirements.

Use the route plan to decide what belongs in your first build. Bring your own facts, review the saved result, and expand only when the core journey works.

What should actually work.

  • Navigation, menu toggles, and form controls work through semantic browser behavior.

  • Local calculations expose their inputs and assumptions instead of hiding fixed sample results.

  • Browser storage is bounded and project-scoped, with a clear explanation of its device-local nature.

Know the service boundaries.

  • Static browser code cannot safely hold secrets or implement trusted server authorization.
  • Source inspection, ZIP download, and repository source pushes remain behind the project’s unlock entitlement.
  • A static export still needs suitable hosting and real services for remote writes, payments, or private account data.

Three places to begin.
Make one yours.

Choose a direction, change the details, and carry the brief into Uvilno. Sign in, name your project, then review the brief in chat before you explicitly send the first build.

Replace the details with your own. Opening a brief does not start a build or use generation capacity.

From a brief to a result you can review.

Uvilno supports static websites and eligible multi-file Next.js projects. The output, connector setup, and execution limits depend on your project’s actual engine and scope.

  1. Plan the journey

    Name the routes, inputs, and expected behavior. Plan mode lets you review and explicitly approve a direction before building.

  2. Build and refine

    Review the isolated live preview, check desktop and phone layouts, and ask for focused changes. Recoverable builds can retain saved draft progress within their retention limits.

  3. Keep the work

    Use Inspect & Edit for supported mapped text, link, and color changes. Unlock source when ready to inspect, export, or use source GitHub sync.

Questions worth settling first.

Can I inspect the code before unlocking?

The live preview is available within the product’s access rules, but raw project files stay private until the project is unlocked or covered by an included source entitlement. Chat should not reveal full source as a way around that rule.

Can static JavaScript use an API secret?

Secrets should remain on a trusted server. Browser code and exported public assets are visible to visitors. A service that requires private credentials needs an appropriate server integration rather than a key embedded in the page.

Can I export the uploaded assets too?

Unlocked exports include the saved project’s included images and bundled fonts with their licenses. Inspect the archive and its integration instructions before deploying it to a compatible host.

What does Uvilno cost, and when can I access source?

Free is $0. A permanent project source unlock is $4.99 once. Plus is $10/month with 2 new project unlocks per paid month; Pro is $20/month and Ultra is $59/month, with unlimited new source unlocks during the paid period. Generation remains usage-limited; the meter shows remaining capacity from 100% to 0%. Already unlocked projects remain downloadable after cancellation.
