What you get

Quick or detailed start

Use Express for only the essential questions, or Advanced to choose more up front.

A working preview

Open the result full screen, click through it and ask for changes before publishing.

Room to keep improving

Feedback, past changes and the current version stay together as the work grows.

How it works

  1. Describe what you want

    Explain the goal, who it is for and what it should do, with no technical specification.

  2. Add your look and examples

    Use your logo, brand details, files or a website you like to explain the direction.

  3. Confirm the direction

    See a plain-English summary and any cost or access choices before paid work starts.

  4. Try the working result

    Open the preview, click around and say what you want changed.

  5. Publish when ready

    Approve the result when you are happy; a preview alone never publishes anything.

You stay in control

  • See the direction and cost before paid work starts
  • Keep passwords and private access out of the conversation
  • Try the exact working preview before release
  • Ask for changes in one clear place
  • Approve the result before it is published
  • Add customer sign-in or private access when the project needs it

The work around the code is part of the product.

What ships today

The Block is not a universal app generator or a generic cloud host. It supports lasting business web Applications whose stack, integrations, risks and access needs are confirmed in the plan.

Source and context

One authorized repository, reviewed business context, uploaded references and the Application's design direction stay together.

  • Existing-repository import or private repository creation
  • Repository-grounded planning
  • Business Profile, Research, files, and Design Assets

Connections and Secrets

Attach approved capabilities without pasting secret values into the Application conversation.

  • Application-scoped Secret attachments
  • Selected allowlisted Connection metadata
  • Scoped, audited access rather than blanket credentials

Hosting and continuity

The web Application runs at a stable platform URL and keeps its database through routine replacements and restarts.

  • Durable Application namespace and hosting
  • Persistent Application database
  • Guided DNS handoff for a custom domain

Review and improvement

Each change stays attached to its plan, run evidence, exact preview, source commit and workspace.

  • Relevant build and test checks
  • Independent adversarial review
  • Explicit owner approval before merge

Questions

Is this only for making a website once?

No. The working version, feedback and future improvements stay together in the same workspace.

Can I bring an existing website or codebase?

Yes. Connect an existing project you have permission to use, or start with a new private project.

Can the result include customer sign-in or private access?

Yes, when that is included in the plan. Tell us who should be able to see and use it.

Can I use my own web address?

Yes. The Block guides you through connecting it and checks the secure address works before marking it active.

What if the work becomes a much larger project?

Turn it into a larger plan with several deliverables, people, stages or budgets. The website or tool stays connected.
