Switzerland has also a pretty new ‘streamlined’ PPR website, called RedFlight. Buochs (LSZC) and Mollis (LSZM) are currently the only ones how use it, but more might follow soon. It offers not only the possibility to request PPR, but also sending customs and immigration forms (automatically) for international flights.
AeroPS however also offers streamlined PPR forms for their customers. As I requested PPR for Bex (LSGB) some weeks ago, the form on their website was actually a web-based app from AeroPS. You can also request PPR through the “RunwayMap” app, which supports PPR forms from AeroPS (exclusively) as well.
And then, there is also AirManager as another competing product to RedFlight. Most Swiss aerodromes use their new CustomsManager to organize customs forms.
