02 The builder
A canvas,
A canvas,
not a form.
Layers, drag handles, brand tokens, per-device styling — it works the way design tools work, because that's what it is. Click anything, edit it in place, publish when it looks right.
TOKENSYour brand, as variables.Colors, fonts, and radii import once and cascade everywhere — restyle an entire popup by changing one token.
BREAKPOINTSPer-device everything.Separate styles, layouts, and triggers for desktop and mobile — tuned on the same canvas, previewed live.
SHIPWhat you see is what ships.The widget renders in an isolated shadow DOM — your theme can't break the popup, the popup can't break your theme.

underneath.
Everything above is the show. This is the machinery — who sees what, which variant wins, and what it's all worth in orders.
Rules with nesting, not checkboxes.
24+ conditions — pages, source, cart, visit history, order count — combined with any/all logic, nested six deep.
The bandit shifts traffic for you.
Run classic A/B tests with significance markers — or flip on bandit mode and let traffic drift toward the winner automatically.
Revenue, not vanity metrics.
Every code and captured email is matched against real orders inside your attribution window. The popup earns its keep, provably.

07 FAQ
Asked &
Asked &
answered.
Everything merchants ask before installing. Something else on your mind? Email us — a human replies.
Will a popup slow down my store?
No. Janus loads asynchronously after your page renders, weighs less than a single product image, and runs in an isolated shadow DOM. Your Core Web Vitals stay untouched.
Do I need a designer or developer?
Neither. Brand import builds an on-brand popup from your URL automatically, and the canvas works like the design tools you already know — click to select, drag to move, type to edit. Zero code, ever.
Can it really import my existing popup?
Yes — paste your store URL and the importer rebuilds your live popup as an editable draft: layers, colors, fonts, images, mobile styles. It's verified against the original with side-by-side screenshots before you touch it.
Does it work with Klaviyo and my SMS platform?
Yes. Every email and phone number syncs instantly to Klaviyo, Postscript, Omnisend, Attentive, or Mailchimp — with signup source, quiz answers, and the offer attached, so your flows and segments just work.
How do the discount codes work?
Janus mints real Shopify codes — unique single-use, shared, or pooled — and can auto-apply them at checkout. SMS-only offers keep the code hidden until the text is delivered, so codes never leak.
Can I control exactly who sees each popup?
Down to the individual condition. Combine 24+ rules — source, pages, cart value, device, visit and order history — with any/all logic and nesting. Existing subscribers are excluded automatically wherever technically possible.
Does it work on mobile?
Beautifully. Every template is mobile-first, every game is touch-native, and triggers can differ per device — exit intent on desktop, scroll-up on mobile.
Is there really a free plan?
Really. Up to 5,000 popup views a month, free forever, no credit card. Paid plans add traffic and remove the small "Powered by" badge — every plan includes every feature we ship.
