Frequently Asked Questions
Is Proovyt a good Demostack alternative? Proovyt is an interactive demo maker where you can change what is on the screen and keep what you make. You click through your product once with the Chrome extension, then blur, replace text, change numbers and add labels on the screenshot itself, on every plan including Free. You share it as a link, an embed or an HTML file you own. Prices are public, from $35 a month for one creator.
How much does Demostack cost? Demostack is quote-only. Vendr reports a median of $32,960 a year, from $21,100 to $52,803, with list onboarding fees of $5,000 on Essentials and $10,000 on Elite. Proovyt starts at $35 a month with no onboarding fee. Checked 6 October 2026.
What is the Demostack Cloner? Demostack's patented Cloner captures how the front end interacts with the backend, producing demo environments that mirror the live product without a backend and reset automatically. Proovyt does not clone applications.
Does Demostack have AI agents? Yes. In June 2026 Demostack launched a Builder Agent that turns a prompt into changes, and Demo Partner, a buyer-facing agent. Proovyt has no AI features yet.
How long does Demostack take to set up? We found only competitor estimates of about 2 to 4 weeks, plus Vendr's list onboarding fees. Proovyt needs the Chrome extension and one click-through.
Is Proovyt built for enterprise presales teams? Not today. Proovyt is built for founders, product marketers and small sales teams who publish demos and buy by card. It has no clones, sandboxes or SSO yet.
How do I move from Demostack to Proovyt? Install the Proovyt Capture Chrome extension and click through the flow once. Each click becomes a step with a hotspot. If you already have screenshots, drop, paste or pick the image files in the editor and each one becomes a step. Then set your brand kit once, and every demo linked to it picks up your logos, colors and fonts.
Does Proovyt keep viewer data private? Hosted Proovyt pages and embeds set no cookies, and analytics store no IP addresses. Every plan shows view counts, and from Creator you see unique viewers, completion rate and drop-off by step.
What does Proovyt not do yet? Sandbox demos, AI voiceover or AI video, branching, CRM integrations, custom domains, SSO and video capture are not available yet. Proovyt works from screenshots on every plan, and Pro and Team also record the page itself with HTML capture, in beta.
