If you are choosing between Walnut and Demostack, the useful questions are practical ones. What can you change on a captured screen, which plan unlocks it, and what will your team pay? This guide answers them from public pricing pages and documentation, then places Proovyt next to both.
The short answer. Walnut is a sales-led demo platform for B2B go-to-market teams, built on HTML capture, with deal rooms and AI agents. Demostack is an enterprise product simulation platform built around a patented cloner and sandboxes. Walnut captures HTML and edits it at template level. Demostack clones the front end and its backend calls into demo environments that reset.

Feature-by-Feature Comparison

Capture and Editing
Walnut. HTML capture through a Chrome extension, screenshot capture, and Figma capture.
- AI Mode rewrites text, finds and replaces across templates, turns text into variables, changes fonts and colors, blurs content and edits HTML tables and some charts.
- Global Edits apply one change across a whole template.
- Its AI cannot generate whole new screens. New screens come from capture, a screens library, or Figma and PowerPoint import.
Demostack. A cloner that captures how the front end talks to the backend, producing independent demo environments that reset automatically. Also Overlay on a production URL.
- Edits to text, numbers, images and workflows in clones.
- Natural-language changes and bulk dataset edits by category.
- A Builder Agent that turns a prompt into a set of changes.
The practical difference is where text edits on a captured screen live.
- Walnut: HTML captures
- Demostack: In clones
- Proovyt: Every plan, Free included

Where Proovyt Fits Next to Walnut and Demostack
Proovyt is an interactive demo maker built around two ideas. You can change what is on the screen, and you can keep what you make.
- Edit the screenshot itself. Blur names and figures, replace a word or a line, change a number, add a label or highlight one area. This works on every plan, Free included. Blur is baked into the pixels when you publish or export, so the original is not sitting underneath.
- Own the file. From Creator at $35 a month billed annually, you can export a demo as an HTML file that plays with no connection to Proovyt.
- Share it safely. Pro at $79 a month billed annually adds password-protected links, expiring links, lead capture and per-viewer analytics with CSV export, all for one person. HTML capture is on Pro and Team and is in beta.
- Pay per seat. Team is $49 per seat a month billed annually, from 2 seats, with everything in Pro for every seat. There is no 5-seat bundle.
Proovyt does not do everything these tools do. Sandbox demos, AI voiceover or video, branching, CRM integrations, SSO and custom domains are not part of Proovyt yet. Custom domains are coming to Pro. If your plan depends on one of those today, weigh that honestly.

Switching Considerations
A switch goes faster when it starts with what you already publish.
- List the demos you publish today. Note which ones need text or number changes on the screen, and which need HTML capture.
- Price the team you actually have. Count creators, not viewers, and check whether a plan forces a 5- or 10-seat bundle.
- Check what you keep if you leave. Ask whether you get a file that plays without the vendor, or only a hosted link.
- Rebuild one real demo first. Capture one flow end to end and share it with a colleague before you move the rest.
The Bottom Line
The choice between Walnut and Demostack comes down to plan shape as much as features. Walnut captures HTML and edits it at template level. Demostack clones the front end and its backend calls into demo environments that reset. If what you need is a screenshot you can change on any plan, an HTML file you own from $35, and per-seat pricing from one person, Proovyt is built for that, and you can start on the Free plan.
