For $50 and a bit of self-hosting effort, you can purchase a license for Foundry Virtual Table Top and get free lifetime updates. The community-built PF2e module is nigh fucking perfect. It's already incorporated the remaster rules.
I do love how easy the PF2 Foundry Game Module is. Sadly my players all want to use Herolab even though its far more user unfriendly. In Foundry you just drag and drop your stuff from the compendium browser.
Mhm thing is that we already bought a dozen or so herolab modules. Thus it's a bit in conflict, furthermore we share our one Foundry server across serveral game worlds and campaigns. So that's also not easily feasible.
But yeah pathbuilder is also a very nice tool, even better imho than herolab.
Is there a direct export to Foundry? I thought there was a Foundry module that imported Pathbuilder's JSON exports, but I don't remember seeing anything in Pathbuilder specifically for Foundry.
I don't use a VTT, though, so I admit I haven't dug too deeply.
