One prompt, one paste
The install is a single line of text with your project key in it. Copy it, paste it into whatever you build with — Claude Code, Cursor, Codex, Lovable, Bolt, v0, Replit — and the agent does the install itself, following the instructions HeyCatch publishes for it.
Pick your framework if you want the prompt tailored: React, Next.js, Vue, Svelte, Astro, Angular, plain JavaScript. The prompt works with any web framework, and a mobile app installs the same way with React Native, Swift, Kotlin or Flutter.
If your site is not in a code editor
WordPress, Webflow, Wix, Squarespace, Shopify and Framer have a setup guide with the snippet and where to paste it in that particular builder. No agent, no repository, same data afterwards.
It checks the install for you
Publish the site, open it once in a browser, then press the button. HeyCatch waits for real events to arrive and only then calls it installed — until it does, the card says it is not.
Better to find out now than three weeks later from an empty chart.
What you see first
Visitors, sessions, pageviews, clicks and total events, each with the change against the previous period, so a number is a direction and not just a number.
Above them sits the written summary of the last thirty days, which is usually the only part you need on a normal day.
What people actually do on the page
The flow map starts at the page they landed on and follows them: how many went on to the next step, how many left there, and what the ones who left did instead. Drop-off is a step of its own, not a missing number.
Below it, every visitor is listed with a short summary of their visits, so a number on the chart can be opened and read as a person.
Where they came from
Traffic is split by source, and the short links you hand to each platform close the loop: a click on the link in your TikTok bio arrives already labelled, so the visit, the session and whatever happened next all belong to TikTok.
Everything else runs on this
The website audit, the recommended fixes and the daily summary all read this data. Without it they work from what your site says about itself; with it they work from what people did on it.
