RunDemo vs Arcade
Arcade turns screens you capture into a clickable, embeddable walkthrough. RunDemo generates a narrated video of your real product automatically. Same goal, two very different formats.
Both tools help you show your product without a live call, but they output different media. Arcade is an interactive demo builder: you capture your product with a Chrome extension, and it stitches the screenshots and clicks into a self-guided walkthrough, an "Arcade", that visitors step through at their own pace and that you embed on your site or drop into outreach. RunDemo is a video generator: you paste your URL and describe the flow, then an AI agent opens your live product in a real browser, performs the steps, and lays a studio-quality voiceover over them, producing a shareable narrated MP4.
The choice comes down to one question: do you want the viewer to click through it themselves, or watch a narrated walkthrough? Here is the honest breakdown.
| Feature | RunDemo | Arcade |
|---|---|---|
| Output format | Narrated MP4 video of your live product | Interactive click-through walkthrough (HTML embed) |
| How it is made | AI agent drives your product; voiceover generated and synced | You capture screens and clicks with a Chrome extension |
| Viewer experience | Watch a guided, narrated video | Click through the steps at their own pace |
| Editing | Edit the transcript; the video re-renders in seconds | Edit captured steps, hotspots, chapters, and blur |
| Narration | Studio-quality AI voice, auto-synced to each action | Text tooltips and captions; AI voiceover as an add-on |
| Embedding | Share a video link or embed the MP4 | Embed the interactive demo on sites and in-product |
| Updating when the UI changes | Re-run against the live product | Re-capture the affected steps |
| Best for | Polished narrated tours, launches, sales follow-ups | Self-serve interactive demos, PLG tours, lead capture |
| Free tier | Yes, first demos free | Yes, free plan |
Where Arcade is the better choice
Arcade is purpose-built for interactive demos, and it is genuinely good at them. When you want the visitor to drive, clicking through your product at their own pace on a landing page, inside an onboarding flow, or in a sales email, Arcade delivers exactly that. Its capture-and-edit workflow is fast and polished, and because the output is an embeddable HTML experience you can add lead-capture forms mid-demo, gate a step behind an email, branch the flow, and read engagement analytics on who clicked what.
If your motion is product-led growth, an interactive Arcade on your homepage that lets prospects try before they sign up is often more persuasive than any video. That is a real strength RunDemo does not replicate, RunDemo produces a video, not a clickable simulation.
Where RunDemo is the better choice
RunDemo wins when you want a finished, narrated video and you do not want to capture anything. There is no extension, no click-by-click recording session, and no re-shoot when your voiceover has a mistake. You describe the flow, an AI agent performs it against your live product, and the narration is generated and synchronized automatically.
It is dramatically faster at volume. Producing twelve feature demos in Arcade means twelve capture sessions; in RunDemo it means twelve prompts. And keeping demos current is cheap: change a sentence in the transcript and the video re-renders in seconds, or re-run the whole demo against your product after a UI change instead of re-capturing every screen.
Interactive walkthrough versus narrated video
This is the real fork in the road. Arcade's output is a clickable simulation the viewer controls; RunDemo's output is a narrated video the viewer watches. Neither is universally better. A clickable Arcade is unbeatable for a self-serve "try it now" moment on a website. A RunDemo video is unbeatable when you need a consistent, on-brand overview to embed in a launch post, send to a prospect, or put at the top of a help article, without narrating it yourself. Plenty of teams run both: an interactive Arcade for the site, RunDemo videos for launches, sales, and onboarding.
