Hi Mel,
Thanks for reaching out to us!
Absolutely you can rely on Ribbet well into the future.
We have a desktop program version for Windows and Mac that runs without Flash and can be downloaded here.
We are also working very hard on a new, HTML5 browser-based version of Ribbet which will also include a bunch of new functionality. If you’re interested in becoming an early, beta tester, you can find more details here.
Or, let us know if you have any other questions!
Regards – The Ribbet Team
