Ask HN: How do you get traffic for your pre-product launches?

I’ve been building small tools lately and trying to get initial feedback and traction before they’re fully “productized.”

I mostly promote to - Hacker news (here) - X/Twitter - Reddit

Curious — how do you get eyes on your projects early on? Any other underrated communities, strategies, or places to share? Would love to hear what’s working (or not) for others!
