Crisp is a customer messaging and live chat platform designed for startups, SaaS companies, and small-to-medium businesses seeking to centralize support, marketing automation, and real-time visitor engagement in a single interface. Websites running Crisp typically embed a JavaScript widget loaded from Crisp's own CDN infrastructure, and our detection engine identifies deployments through one distinct script pattern and one HTML pattern — commonly a script tag referencing the `client.crisp.chat` domain alongside a corresponding HTML attribute injected into the page markup. These signals are reliable indicators because Crisp's widget initialization follows a consistent fingerprint, inserting a global `$crisp` configuration object and a recognizable `data-id` or similar attribute tied to the workspace identifier. The combination of script and HTML pattern matching allows the detection engine to distinguish Crisp from competing chat platforms with high confidence, even when the widget is loaded asynchronously or deferred. Crisp operates on a freemium model with its official presence at [crisp.chat](https://crisp.chat), offering a permanently free tier for basic chat — a factor that contributes to its broad adoption across lightweight landing pages and early-stage product sites, making it one of the more consistently detectable chat tools in our database.
