Interactive Demos for Web Design Agencies
August 21, 2026
Design agencies have portfolios full of screenshots and live links, both of which show what a site looks like and neither of which shows what it does.
The gap matters most in two places: the pitch, and the fortnight after launch when the client cannot remember how to edit anything.
In the pitch
A live link sends a prospect to a site with no guidance — they poke at it, miss the thing you were proud of, and form an opinion from the homepage. A demo walks them through the flow you designed, in the order you designed it, with a caption on each decision.
It also works for sites you cannot link to: client work behind a login, an internal tool, something under NDA where a captured and redacted flow is showable and the real thing is not.
At handover
The most valuable demo an agency makes is usually the CMS walkthrough: how the client edits a page, adds a post, swaps a hero image. That is where post-launch support hours go.
Record it once per project. It takes an afternoon and it removes the same three emails from every launch, which is a cost you can actually feel.
What to capture
- The editing flow, not the front end. The client already sees the front end.
- Screenshot capture for anything visual -- animations, canvas, unusual layouts -- since HTML capture cannot reproduce a canvas.
- Redacted client data, because a CMS is full of it. Blur destroys the pixels rather than covering them.
- The mobile view, which is what the client will check first and complain about first.
The practical setup
Demos live in one workspace with no client folders, so a naming convention does the work: "ClientName — CMS handover", "ClientName — Pitch". Placement first, because that is how you will search for it.
The 5-demo free plan covers a couple of projects. Beyond that, Starter at $15.99 a month is unlimited demos with Demorta branding removed, which is the plan most agencies actually need.
Frequently asked questions
- How do web design agencies use interactive demos?
- Two main ways: walking a prospect through a designed flow in the pitch, in the order intended rather than letting them poke at a live link, and recording a CMS walkthrough at handover so the client can edit their own site without emailing you.
- Can I demo client work that is behind a login or under NDA?
- Yes, and it is one of the strongest uses. Capture the flow, redact anything sensitive -- blurring destroys the pixels rather than covering them -- and you have something showable where the live site is not.
- How do agencies organise demos for multiple clients?
- With a naming convention, because Demorta has no client folders or sub-workspaces -- one workspace holds every demo. Lead the name with the client and the placement, such as "ClientName - CMS handover".
