// THREAT ASSESSMENT

"Book a demo" is where evaluations go to die.

Your product is self-hosted. That means every prospect's journey starts with install docs, a Docker command, and a free evening they don't have. Most never make it.

// THREAT ASSESSMENT

"Book a demo" is where evaluations go to die.

Your product is self-hosted. That means every prospect's journey starts with install docs, a Docker command, and a free evening they don't have. Most never make it.

[ 01 ]
Click-through tours are fake
Prospects can tell they're clicking screenshots. A staged walkthrough proves nothing about whether your software actually works for them.
[ 02 ]
Hosted sandboxes are costly
Rent servers for every visitor and your demo becomes a cost that punishes success. And adds another infra for your team to support.
[ 03 ]
"Contact us to see a demo" loses the room
The engineer evaluating you at 11pm will not book a call. They close the tab. You never even knew they were there.
// OPERATION SEQUENCE

How Demoshell works

STEP
01
You build the demo in web browser
Demoshell demos are like Docker images that run in a web browser. To create your own just sign up, pick a base image, paste a short install script and press Build — your demo is baked right in the browser and hosted on our CDN as a compact snapshot.
STEP
02
Share the link or embed the demo on your website
Each demo gets a public link and embed code so that you can integrate it into your journey. We will keep monitoring your Github for new releases and automatically build a new demo whenever a new version is published.
STEP
03
Every visitor boots a private instance. In their tab.
Our WebAssembly virtual machine runs your actual software on the visitor's own hardware. Each session is isolated and disposable, and runs on the visitor's machine — so a thousand simultaneous demos cost you no more than one.
// SUGGESTED SOLUTION

FOR YOUR VISITORS
▸
Real software, not a recording
A working terminal and the real UI. They can run commands, click around, break things, and restart.
▸
No signup wall
The demo starts before they've decided whether to talk to you. That's the point.
▸
Loads in seconds
Pre-booted snapshots stream from a CDN. No provisioning, no queue, no "your environment is being prepared."
▸
Rebuilds when you release
Version watches spot your new release and rebuild the demo from its build script — your demo never embarrasses you with last quarter's version.
FOR YOUR PIPELINE
▸
Unlimited sessions, flat fee
Demos run on the visitor's hardware. Go viral on Hacker News; your invoice doesn't move.
▸
Guided scenarios
Turn your quickstart into interactive steps. First-run experience, designed once, delivered to every visitor identically.
▸
Lead capture at the moment of intent (coming soon)
Ask for the email when they're deepest in the demo — not before they've seen anything.
▸
Funnel analytics. (coming soon)
See how many started, where they dropped off, which guided step loses people, which converts them.

Questions engineers ask

How does real software run in a browser with no servers? [ − ]
Demoshell is built on a WebAssembly virtual machine that emulates a full Linux environment inside the browser tab. Your Docker image is converted into a streamed disk snapshot; the visitor's browser pulls only the blocks it needs from a CDN. All computation happens on the visitor's machine.

Is it secure? [ + ]

What do you actually host? [ + ]
Does it work on mobile? [ + ]
