No metadata. No tracking.
VaultChat started as an idea, not as a coding project.
I couldn't write code, read code, or build apps myself. What I had was a problem I wanted to solve: private communication without phone numbers, emails, accounts, or central servers.
Using AI tools like ChatGPT and Claude, and many months of testing, learning, failing, rebuilding, and testing again, VaultChat slowly became real.
Today it's a fully working encrypted messenger built on Nostr: • No phone number • No email • No central server • End-to-end encrypted • Open source
I'd genuinely love your feedback, especially on privacy, usability, and what you'd like to see next.
Thank you for checking it out 🚀

Who hunted VaultChat?
VaultChat was hunted by VaultChat. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.
