In plain words
Notesnook is an end-to-end encrypted notes application that became open source in 2022. It is designed for users who want to keep their notes private and secure. The app encrypts notes on the user's device before they are stored, meaning only the user can access their content. Being open source allows anyone to review the code and verify its security practices, making it suitable for individuals and teams prioritizing privacy in their note-taking.

MinkNoteJul 2026 · muse23.com · ▲157Private macOS notes app built on plain Markdown files. No databases, no lock-in. Native, keyboard-first, and designed for knowledge organization.
Burner NoteJan 2026 · burnernote.com · ▲222In 2021 after getting thoroughly sick of Privnote, i built "Burner Note". Even though i didn't promote it in anyway other than a post here and a post on reddit, it ended up getting about 7000(ish) unique users per month. I kinda let it die about 18 months ago but i've resurrected it with some big upgrades. Most botable the app is now truly end to end encrypted (previously was just server side), and I've added dark mode as well as a few other bells and whistles. Feedback welcomed.

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client.

That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly. This model can be used to disrupt any marketplace from AirBNB to UberEats: building tech for home renters and restaurants and later, leveraging that to build a competing…
