Questions
Licences, plainly.
Can we use the Community edition in our business?
Yes. Apache-2.0 lets you run it, change it and use it commercially without paying. Keep the licence and the notices with any copy you pass on.
Are the agents open source?
No. The agents for Chrome and Office are free to use with any Fadenstack server, but their code is not published. Their terms of use come with the first release.
The SDKs they are built on are open source, so you can build agents of your own.
What will Enterprise cost?
Prices come with the edition. If you need what it will include, tell us and we will talk it through.
