BuildStack is a modern PC building platform that eliminates compatibility headaches. Select components across 8 categories, get instant compatibility validation, and receive AI-powered explanations when issues arise. No more guessing if your CPU fits your motherboard or if your PSU can handle the load.
Hey Product Hunt!
I built BuildStack after watching friends make expensive compatibility mistakes while building
their first PCs. One bought DDR5 RAM for a DDR4 motherboard. Another picked a GPU that physically
could not fit in their case.
The problem is not lack of information. Spec sheets exist everywhere. The problem is that checking
compatibility requires cross-referencing multiple sources and understanding technical jargon.
BuildStack solves this by:
1. Showing only compatible parts as you build
2. Explaining issues in plain English when they occur
3. Suggesting alternatives with one click
The AI integration was particularly interesting to build. When DeepSeek detects an issue, it does
not just say "incompatible." It explains why socket mismatches matter, what happens if your PSU is
undersized, and exactly which parts would work instead.

Would love your feedback on:
- What compatibility checks should I add next?
- Any UI improvements for first-time builders?
- Features that would make you use this over existing tools?
