Whats unity pro vs unity free

Ok I don’t mean to sound new but I am Haha
I’ve had an idea for a game for awhile but I needed a 3D engine and someone told me to download unity so I did, when I signed up for it, it stated it was free and full but then after registering it said I only had 30 until it ended and I had to pay. . .

So my question is, is there a free version or does my version (the pro) turn into the free version after the thirty days and if so, what’s the difference between unity pro and unity free??
Will I still be able to use 3D rendering and the 3D portion of unity or no?
And also if anyone has a link to maybe a website that tells the difference between the free and pro version that would be awesome

Thanks!

Recap: What will happen after the 30 days? Is there a free version or does it turn into it or does it lock unity? What’s the difference between the free and pro versions? And finally if I want to make a 3D game will the free version be good enough?

Read Powerful 2D, 3D, VR, and AR software for cross-platform development of games and mobile apps.. Unity Pro has full features whereas the free version is limited (but sufficent for casual games).

Please note that Unity Answers is not the place to discuss such matters, as stated in the FAQ (at least as much as I understand it).

And finally, free is good enough to make and publish games. You need Pro if you need Pro features.
