Hi Product Hunt!

I'm Mark, solo dev and co-founder of Moss Piglet a privacy-first public benefit company.

Habit tracking is personal. Your goals, your struggles, your progress that's some of the most intimate data you can generate about yourself. So why does every habit tracker out there store it in plaintext on their servers?

Metamorphic is a zero-knowledge encrypted habit tracker. Your data is encrypted in your browser before it ever leaves your device. The server never sees your habits, your goals, or your progress. Not even we can read it.

Hey Product Hunt!

We just went live with the SigmaMind MCP Server, and we re on a mission to end "infrastructure hell" for voice developers.

For the last year at SigmaMind (YC S22), we ve watched builders struggle to stitch together telephony, low-latency models, and fragmented APIs.
Today, we re changing that. We ve built a way to configure and deploy production-grade voice agents directly from your IDE (Cursor, Claude Code, etc.) using the Model Context Protocol. No more manual glue - just one prompt to connect your model, pick a voice, and get a live phone number.

We d love your feedback on the launch today:

A few users who create sea route animations told us something simple:

Everything looks great but the distance is in km.

For ocean routes, nautical miles are the standard.
