I'm pretty sure figma clone cannot be done in 8k lines. Are you only cloned part of the logic?

I wish there was a more standardized way of sharing these prompts, results and token usage.

Can Mana clone Mana yet?

Not surprising it can get it to parity for a casual user. One thing I find though is that a lot of the vibecloned apps miss or ignore power user features or implement edge case features incorrectly. This was very, very true of the artcraft clones - as soon as you get to the more advanced things, they start to fall apart.

For a lot of the Figma code, there are SO many gotchyas in there, that while I'd be curious to try it, I don't think agents would be able to derive the why, and thus would attempt to optimize the implementation leading to incorrect usage. I led the variables workstream at Figma, and it still is the most complex thing I've worked on in my 20 years of tech. The amount of edge cases / conditionals / exceptions in it are staggering, just to get it to a point where it seems like it's "simple" (for a power users' definition of simple).

One other thing to consider though is the value of something like Figma isn't the functionality so much as the multiplayer platform aspect. This is toats fine if you're just doing solo work, but the collab aspect means you have to fight against the social network dynamics, which also can't be vibe coded.
