Free Interactive Demo Software: What You Actually Get (2026)
Every demo platform says "free." Here's what each free plan actually includes — and the three gates that decide whether free is usable.
Almost every interactive demo platform advertises a free plan. The real question is whether the free tier produces a demo you'd actually put on your website — or whether it's a teaser designed to hit a paywall the moment you try to publish. Here's how the free plans really compare in 2026, and the three gates to check before you invest an afternoon in any tool.
The three gates that make or break a free plan
- Capture quality — does free include real HTML/DOM capture, or screenshots only? This is the biggest silent gate in the category.
- Publishing — can you actually publish and embed the demo, or only preview it inside the tool?
- Watermarks and limits — how loud is the branding, and how many demos or steps before you're forced up a tier?
Mirage — HTML capture and publishing, free forever
Mirage's free plan includes the thing competitors gate hardest: full DOM capture of your live product. You get the complete editor — hotspots, spotlight, camera zoom, themes — plus one published, embeddable demo with step analytics, free forever with no credit card. The limits: one published demo, one hotspot per step, and a small badge on the player. Pro ($20/mo) removes the caps and the badge, and adds custom slugs and unlimited demos.
Arcade — free for short screenshot flows
Arcade's free tier is fine for quick, screenshot-based clips you share on social. For embedded website demos, screenshot capture is the ceiling — text softens under zoom and layouts are frozen.
Storylane — free entry, HTML capture upstairs
Storylane's free plan gets you started with screenshot capture, but HTML capture and the conversion features live in paid tiers — several rungs up. Budget for the real price if you outgrow screenshots.
Supademo — free with per-seat scaling
Supademo's free tier is serviceable for individual use. Costs arrive when your team joins (per-seat) or when you need branding and advanced capture from higher plans.
The honest summary
If "free" needs to produce a crisp, embeddable demo of your real product, Mirage is the only tool in the category that includes DOM capture at $0. If you just need a quick screenshot flow for a tweet, any free tier will do.
When to upgrade from free
Upgrade when a demo starts producing pipeline: you want multiple demos live, your own branding, custom slugs, and deeper analytics. Until then, ship the free demo and let the data argue for the upgrade.

Start freeFrequently asked questions
Is there genuinely free interactive demo software?
Yes — Mirage, Arcade, Storylane, and Supademo all have free plans. Mirage's is the only one that includes full HTML/DOM capture and a published, embeddable demo at $0, free forever.
What's the catch with free demo software?
Usually capture quality (screenshots instead of HTML), publishing limits, or watermarks. Check whether the free tier lets you publish and embed a demo you'd actually put on your homepage.
How much does interactive demo software cost after free?
Mirage Pro is $20/mo. Mid-market tools run $40–120/mo per seat, and enterprise platforms like Navattic and Walnut climb to $350–500+/mo for the tiers with HTML capture and branding control.
