What is the Early Access Program (EAP)?

We at JetBrains believe that making good tools for developers should greatly rely on developers' opinions. Our Early Access Program lets the development community closely participate in discussions devoted to JetBrains MPS and influence the planning and development from the early stages onwards. We hope this EAP will be both valuable and exciting, just as EAP program for IntelliJ IDEA is. We highly appreciate your feedback and ideas!


It is important to distinguish EAP from pre-release software.

YOU EXPRESSLY ACKNOWLEDGE THAT THIS VERSION OF THE PRODUCT MAY NOT BE RELIABLE, MAY NOT WORK AS INTENDED AND MAY CONTAIN ERRORS. ANY USE OF THE EAP PRODUCT IS AT YOUR OWN RISK.
