    Everything you need to prototype faster

    From spec to live prototype in seconds, with all the tools government teams need.

    AI Code Generation

    Write a natural-language spec, get a working prototype that follows GDS standards — templates, routes and validation.

    Live Sandbox Preview

    Generated prototypes run instantly in isolated cloud sandboxes with shareable URLs for user research sessions.

    Conversational Iteration

    Chat with AI to refine your prototype — add pages, change flows, fix content in real-time.

    File Browser & Editor

    Browse generated files with syntax highlighting. View Nunjucks templates, routes, and configs.

    GitHub Integration

    Push generated code directly to GitHub. Create repos, commit changes, manage versions.

    Secure by Design

    TLS in transit, AES-256 at rest, RLS-isolated workspaces, UK data residency, no prototype data sent to AI training sets.

    Accessibility Built-In

    Every generated prototype follows GDS design patterns and WCAG 2.1 AA standards by default.

    Template Library

    Start from pre-built service templates — applications, eligibility checks, dashboards, case management.

    How it works

    From idea to interactive prototype in four simple steps.

    Write Your Spec

    Describe the service journey in plain language — what citizens need to do.

    AI Generates Code

    Our AI creates a complete GOV.UK prototype with Nunjucks and React.JS templates.

    Preview & Iterate

    Interact with the live prototype in your browser. Chat with AI to refine flows and add features.

    Share & Export

    Share the live URL for user research, push to GitHub, or export the code for deployment.

    What Vibe.WithGov.io does

    A GOV.UK Design System prototype, generated from a service spec

    Describe the user journey in plain language; Vibe.WithGov produces the GOV.UK Prototype Kit templates, Express routes, validation and accessibility a researcher can put in front of a real user the same day.

    How a prototype gets built

    1. Write a spec in plain English

      "An applicant applies for a fishing licence: name, address, date of birth, licence type, payment." No syntax, no templates.

    2. Vibe drafts the journey

      Pages, routes, fields, validation rules, and the start and confirmation pages — generated as one coherent service.

    3. Iterate by conversation or code

      "Add an eligibility question before the name page." Or edit the Nunjucks and routes directly in the built-in editor.

    4. Share for research

      Hand the sandbox URL to research participants, or export the Prototype Kit project as a ZIP and push it to GitHub.
