Woah - just tried it out and I was definitely surprised about how great of an experience I had. The user interface, controls, and design is beautifully done - the graph is excellent. Great job!

The product undoubtedly addresses a need: no campaign was necessary, everything was done by word of mouth, entirely online.

If you use data from multiple sources on a regular basis, Castor will be your new BFF. It helps you visualize data from multiple sources in one place. Castor is also great to present your data on a large screen, so you can share relevant data to your entire office or team – from sales insights to user onboarding analytics, including servers and app status.

You can also use Castor to display live information whenever you need to. Whether it’s conference signage or waiting room display, Castor will help you communicate easily. We love hearing about solutions our users build with Castor — share your Castor love with us via Twitter (@getcastor) or send us pictures of your setup at [email protected].
To edit and display a Castor dashboard, you need a modern web browser. You can use any web browser as a screen, including iPhone and iPad. You can use a large TV screen to beautifully present your dashboard in your office – just remember we don’t provide you with the TV!
If you only need one dashboard, you’ll love our Free version of Castor. You can even display your dashboard on as many screens as you want. If you need more than one dashboard or want to send data directly from your app or server to your Castor dashboard using webhooks, consider the Pro plan that comes with unlimited dashboards and webhooks.
We ask you to pay a small fee for Castor Pro to cover server costs, services costs (like our Weather service) and future development of Castor. We still wanted to offer a free version of Castor, that's why the Free plan is on us!
By default, Castor will always ask the client browser to fetch the data itself so no data actually goes through our servers. However, if it fails, Castor server will try to fetch the data — make sure you read the article “Remote Data with Castor” from our documentation. When Castor server fetches data, it securely pipes it directly to the Castor client. No data is stored or cached.


Our developer-friendly documentation provides you with useful articles from editing your dashboard to creating custom widgets.
