# You'll be familiar with web bugs, the transparent images which track when someone opens an email. They work by embedding a unique URL in a page's image tag, and monitoring incoming GET requests.
# Imagine doing that, but for file reads, database queries, process executions or patterns in log files. Canarytokens does all this and more, letting you implant traps in your production systems rather than setting up separate honeypots.

# With Webhook.site, you instantly get a unique, random URL and e-mail address. Everything that's sent to these addresses are shown instantly. With this, you can test and debug Webhooks and HTTP requests, as well as create your own workflows using the Custom Actions graphical editor or WebhookScript, a simple scripting language, to transform, validate and process HTTP requests in a variety of ways – without setting up and maintaining your own infrastructure.
