Everything you need, nothing you don't
Server-side personalisation without cookies, consent banners, or engineering sprints.
Know which variant wins
Track impressions, engagement, and conversions per variant and per segment. See exactly which audience responds best to which message. Export raw data to your BI tool at any time.
Your CMS, your content
Variants live in Sanity, Storyblok, or Statamic — wherever your editors already work. Mister Chameleon fetches and serves the right variant; it never duplicates or replaces your content.
Run experiments without engineering
Create a new variant in your CMS, define the audience rule, set traffic weights — and you're running an experiment. Results appear in the dashboard with statistical significance indicators. No code deploys needed.
Connects to your full stack
Works with any CMS (Sanity, Storyblok, Statamic, Contentful, Prismic), any analytics platform (GA4, Plausible, Mixpanel), and any CRM (HubSpot, Salesforce). Add custom enrichment sources via the API.
One platform, many brands
Agencies and enterprise groups can manage dozens of client websites from a single dashboard. Each tenant gets its own CMS connection, segment library, and analytics. Full data isolation between tenants.
GDPR-compliant by design
All personalisation decisions happen server-side before the page is served. No client-side tracking, no cookie banners, no consent pop-ups. Fully compliant with GDPR, ePrivacy, and CCPA out of the box.
Trusted by B2B marketing teams
“We went live in a single afternoon. Within two weeks our demo-request rate was up 34%. The fact that it runs server-side and requires zero cookie consent was the deciding factor for our privacy team.”
Thomas van den Berg
Head of Growth, Payt
“I used to write tickets for every personalisation experiment. Now I open the CMS, add a variant, define the segment rule, and it's live. The engineering team has no idea I'm even running experiments.”
Eline Smits
CRO Manager, Sendcloud
“Managing personalisation for 18 client websites from one dashboard is a game changer. The multi-tenant setup is solid — complete data isolation, separate CMS connections, everything.”
