The FemtoOS is dual licensed. For most uses the free GPLv3 license will be best. However, GPLv3 comes with a number of obligations, and the Femto OS is delivered 'as is'. For example you have to publish your code along with mine if you deliver to others, even if you only use the api of Femto OS (since applications and the OS are always compiled simultaneously and are very interwoven by nature) Even if your code is embedded that obligation exists. Furthermore, if the code is flashed (and not permanently fixed) you must also publish instructions how it can be modified. See the GPLv3 for all the details.

If this is not to your liking, there is the possibility to obtain a commercial license. The advantage of the latter is that you will obtain the latest tweaks from the author, inside documentation and support. Note that the commercial license is targeted at large scale application. Please contact me for details.
