Pertento Editor

Visual editor for Pertento experiments

Pertento: lightweight, privacy-first experimentation Build A/B tests and personalised experiences directly on your live site, from Chrome's side panel. No developer needed, and no compromise on performance or privacy. Edit any page visually • Click any element to change its text, images, links, colours, spacing and layout • Double-click text to edit it in place • Style hover, focus and active states without writing CSS • Duplicate, hide, move or remove elements, and apply a change to every matching element, including ones that load later • Full HTML, CSS and JavaScript editor when you want code Add ready-made sections • Drag in designed blocks: hero, features, call to action, testimonial, FAQ, accordion, trust row, logos, pop-up, sticky bar, announcement bar and more • Video, image slider and gallery components • Components pick up your site's fonts and colours automatically, so they look native from the start Personalise with live data • Show each page's own product name, price, rating or stock, built once for every product page • Use campaign (UTM), visitor, date and cart data: countdowns, free-shipping bars, messages that match the ad a visitor clicked • Connect your own data feeds (JSON or Google Merchant) for reviews, stock levels or campaign copy • Missing data never shows as a broken placeholder Work with confidence • A clear list of every change, with reliable undo and redo • Preview a variant on desktop and mobile, or share a link to check it on any device • Your work is kept if a save fails, and you can retry Why Pertento • A loader under 1 KB, and advanced features only load on sites that use them • Privacy-first: European infrastructure, no cookies • Statistics built for real traffic: sequential analysis (SPRT) and other methods for early, valid conclusions • Works with any website, CMS or e-commerce platform Permissions The editor asks for access to a website only when you open it there, so it can show and apply your changes on that page. It doesn't read other sites. Requires a Pertento account and Chrome 116 or newer.
