Yes, Caido is free to use. However, we also offer a pro tier which will include additional advanced features in the future. By purchasing the pro version, you will be supporting the development and maintenance of the tool.
Additionally, we offer an enterprise plan for organizations that need premium support and/or custom feature implementation.
You can check our website to stay informed about the new features that will be added in the future.
Caido is not currently open source, but we have plans to offer an API for open source plugin development. We also employ standard open formats whenever possible.
At this time, Caido can be installed on an unlimited number of devices. You are welcome to install Caido on as many devices as you like.
When you register for Caido, we collect your name and email address, as well as information about your user agent.
When you use Caido, we collect interaction data between your instances and our cloud services. This includes the IP address of the instance and API call actions/timestamps.
We do not collect any data stored on your instances nor interactions within the caido application.
The Caido CLI is self-contained binary that launches the Caido proxy (also called instance). You can use it on remote servers or locally and access the instance using your browser. The Caido Desktop acts a connection manager to your instances and can also launch the Caido proxy in the background. It uses webviews to access the instance instead of the browser.
WARNING: At the moment, Caido Desktop is considered experimental and does not perform as well as the browser on Linux.
