Hey Product Hunt! 👋 Thanks so much for hunting us, @vancuren! I got tired of building in the dark (tokenrouter.io, necter.ai, sanitycheck.dev, etc).

SanityCheck Validate your startup idea in minutes — not months.
Stop building in the dark. Stop asking your mom if your startup idea is good. Stop guessing whether people want what you're about to spend 3 months building (or 3 days vibe coding).
I made a fix: SanityCheck.dev
You post your idea.
The internet tells you the truth.
You get real signals, not optimism bias.
If you’re brave enough, submit your idea: sanitycheck.dev
