    Balsamiq vs Vibe.WithGov

    Sketch-fidelity wireframes versus a clickable GOV.UK prototype. Different fidelity, different stage of the work.

    Balsamiq is a low-fidelity wireframing tool with a deliberate hand-drawn aesthetic. The look is the point: sketchy outputs say “this is a draft” in a way polished mockups don’t, which keeps early-stage critique honest. Vibe.WithGov is for the opposite end of the journey: a clickable, accessible GOV.UK prototype that research participants can use as if it were a live service.

    These tools fit different moments in the sprint. The matrix is for the moments when teams are choosing between them.

      Different jobs. Some teams use Balsamiq for the first week of discovery and Vibe from there.

    When Balsamiq is the right call

    • The team is in the first days of discovery and the design question is still “what could this even look like?”
    • You’re running a workshop where the sketchy aesthetic is a feature: it keeps participants critiquing the idea, not the pixels.
    • Stakeholders need a quick visual to align on before the team commits to a direction.

    When Vibe is the right call

    • The team has shaped the journey enough that it’s ready for user research.
    • The prototype needs to look and behave like a real GOV.UK service: components, accessibility, validation, the lot.
    • You’re heading into a service assessment and need evidence the panel will accept.
    • Participants need to type into forms, hit errors, recover from them.
