ProtoFluid Core
The core version of ProtoFluid is free!
This deliberately breaks from the software-as-a-service subscription pattern. Instead, ProtoFluid's approach is similar to the freeware model.
The core version includes the essential feature set.

ProtoFluid Pro
ProtoFluid Pro unlocks unlimited viewports and windows.
It also includes a fullscreen mode toggle and ‘wake lock’ functionality for unattended demos.
One-off payment of €10, including free future enhancements.
Add-ons
Every add-on you buy is yours forever. Updates are free.
Sorry, no refunds.
Please use the free version of ProtoFluid for as long as you like. You do not have to purchase anything.
ProtoFluid Pro and the add-ons are just nice-to-have extras.
Buying an add-on gives you the file forever. Due to the ease of copying a file, returns are impossible, so refunds are impossible.
If you don't think ProtoFluid's core feature set is of a high enough quality, please don't buy ProtoFluid Pro or any add-ons.
One-off payment
Purchasing ProtoFluid Pro or an add-on is a one-off per-developer payment.
Licensing
You can use ProtoFluid Pro and any purchased add-ons across all your devices and browsers.
Please do not share premium add-ons.
