The Sanoodi version 22.214.171.124 is based on Google Maps API. It works well, rarely reporting errors. Today, I migrated my account to Sanoodi Beta available for mysterious Friday the 13th (month unspecified :-)). Besides new & ugly user interface, I’ve encountered that mapping capabilities in Beta are based on OpenLayers engine. Great choice, if my vote counts. The core of Sanoodi application is based on Django framework. Another good choice :-)
If you are doing any outdoor activities, Sanoodi is a nice gadget and worth to try. I recommend to use version 126.96.36.199 for regular diary. In my opinion, the Beta version is still unusable. It is throwing errors while saving preferences or uploading GPX file, Save button for new route sees to be not even linked, etc. BTW, I’ve reported all my problems to the Sanoodi Team. Hopefully, they will fix it soon.
