It gets even more complicated if you wish to be a small time business. SaaS in CAD is just.....downright Adobe level of inconvenient IMO.
Fusion 360 -> free, but share your stuff with them. Cloud-based, arguably buggy at complex projects. €760 per year
Solidworks-> by offer, not for one-man army.
Onshape -> free, but you share everything, cloud-based. If you want paid license, $1500 and up, not for one-man army
Design SparkMechanical -> kind of powerful, but mainly electronics oriented. Complex learning curve IMO
SolidEdge (Siemens) -> very good feedback, $200-400 per month minimum, depending on what you need
Alibre Design -> off line!, local storage of files, one-time purchase, (my personal favourite). Price is by offer, but expected ~€1600
FreeCad -> free for commercial project. A must start IMO for CAD work
Ondsel -> Freecad with paid cloud storage and arguably more user-friendly interface. (may be the future of Freecad??, where there is money, there is progress, yes?)
