Thanks for helping test Cyd

Are you helping test out features in Cyd? Thank you so much! You're making it so much better.

This page is for people who are running the dev version of Cyd to help test it.

Here's a note about how to access premium features while you're testing, followed by instructions on how to download the dev release for your computer.

Accessing Premium features while testing

The dev version of Cyd uses a dev server which limits what email addresses are allowed to sign up for Cyd accounts. You can only sign up if you've spoken with us and we agreed to let you test.

Once you're signed into your dev Cyd account, you can sign up for Premium using the following test credit card:

  • Card number: 4242 4242 4242 4242
  • Expiration date: anything in the future
  • Security code: make it up
  • Billing address: make it up
