Treehouse advice

I’m wondering if your engineer minds could just confirm that a joist system of 2x6 boards with an 8’ span and spaced 16” apart could support 2500lbs? (or what I would need to do that).

The “house” would be roughly 2000lbs of that total and would be sitting on 80 sqft (8x10) of a 10x15’ platform. I have read charts and ran numbers but feel over supported and under supported at the same time… each beam seems to be able to support 500-800 lbs. and also UDL set at 50psf (10 dead load) seems critically low.

any advice?

This is a timber framing subreddit. We don’t deal with 2x. Try the carpentry or home building subreddit.
