Who hunted Encoder?
Encoder was hunted by Victor Pratti. 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.

Hi Product Hunt, maker here 👋
I kept needing to send someone a password or an API key, and every channel I had (WhatsApp, email, Slack) just keeps it. Forever. In two inboxes, in backups, on linked devices, in a screenshot someone forgot they took.
So I built Encoder. You write a message, it's encrypted in your browser, and you get a link. Whoever opens it reads it once — the moment it's opened, the record is deleted from the server.
How it works, for the curious: the decryption key lives in the part of the URL after the "#", which browsers never send to a server. So my server only ever stores ciphertext it can't read.
Being upfront about the limits:
• It's closed-source for now (open-sourcing is on the roadmap)
• No third-party security audit yet — it's a solo build
• It fixes the storage problem, not screenshots: nothing can stop someone photographing their screen
• The link itself is sensitive until it's opened
Pricing: a few free messages to try it, then $19.99 once for unlimited sends. No subscription — I didn't want to add another recurring charge to anyone's life.
I'd love feedback on two things: is the one-time-link flow clear on first use, and would you trust it more with an audit or with open source first? I'll be here all day answering questions.
