In addition to the free Nuke version, which can be used strictly for non-commercial work, The Foundry now also offers a somewhat slimmed down Nuke Indie version for solo independent motion artists. Those who do not earn more than 100,000 dollars a year with their assignments and do not get involved in other (agency) pipelines are allowed to use the software for 449 Euros per year. In other words, for a fraction of what the "big" Nuke Studio's subscription fee is, namely 12,596 Euros per year.
Nuke Indie combines the node-based compositing tools from NukeX with Conform + Editorial features from Nuke Studio, but is limited in some points. For example, the output is limited to max. 4K resolution and H.264 cannot be processed. BlinkScript is fully supported, Python only limited (up to 10 commands). As it seems you have to do without plugins, because there is no support for NDK or third-party plugins, as well as the possibility to render externally.
Projects created in the indie version are saved in an encrypted file format, so they cannot be opened by the "big" nuke versions. In addition, the license must be verified online at least every 30 days, and every 90 days the software must be updated to the latest release. For more information, see also 
Nuke Indie FAQ.
At the same time, Nuke 12.2 is released with some new features and improvements, e.g. Sync Review for collaborative working (but logically disabled in Nuke Indie), support for Pixar's Universal Scene Description (USD), a new QuickTime implementation, extended DNxHR and RED support (see Release Notes).
