A Few Examples Of OPA

OPA is a language that allows fast and simple development of web applications. Below are listed a few examples of OPA to get started in a few minutes, even with little knowledge of programming.

If you want to delve further into the language, you can find a tutorial and the reference manual on the OPA documentation page. You can test an OPA-powered application with this demo (this is a multi-user app, if you are alone: try opening it in two browsers... iPhone included).

    First, thanks for all remarkably good internship applications we received. All positions are now taken, and our whole team is now working on exciting new features.

    The next version of OPA, scheduled for the end of March, will feature an extended, much improved standard library. We're also working on building a faster compiler and we hope it will be ready in time to be included in this next release. Stay tuned!
