Utiliti – Online and OSS Utilities (Private Notes, JSON Viewer, etc.)
Hi HN! I was recently on a sabbatical and wanted to checkout the advancements in the frontend space. I would love to show you all https://utiliti.dev! I often find myself resorting to online web-based utilities, especially for things like note sharing, or viewing JSON as a tree when my IDE isn't open. Having used a few tools in the past, I was never sure what those tools were doing so I ended up building something myself and open sourced it. Highlight: I really enjoyed building private notes, an easy and quick way to share something private over email that gets destroyed on read…
Utiliti – Online and OSS Utilities (Private Notes, JSON Viewer, etc.) launched on April 5, 2023 with 14 votes, #1,613 of 4,853 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 3 years on.
In plain words
Utiliti is a collection of open-source web-based utilities for developers and general users. It includes tools like a private note-sharing service that self-destructs after reading or a set time period, a JSON tree viewer, and other utilities for tasks commonly performed outside an IDE. The project is built with Remix and Tailwind, hosted on Cloudflare, and made available because the creator wanted transparency about what online tools do with user data.

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.
NotesHub: cross-platform, Markdown-based note-taking app2024 · about.noteshub.app · ▲147Thank you for your comments, just some context: - The app is available for iOS, Android, Windows, Mac, Apple Vision Pro, and the Web. - The Web version is implemented as a Progressive Web Application that is very responsive, local first, offline first, can be installed, and is entirely free to use. - Native (hybrid) versions do not require subscription fees and have small one-time payment. - You can store your notes in Git using any Git provider such as GitHub, GitLab, or Bitbucket. However, it has the best built-in integration with GitHub. Self-hosted scenarios like Gitea are also…
ut – Rust based CLI utilities for devs and IT2025 · github.com · ▲170Hey HN, I find myself reaching for tools like it-tools.tech or other random sites every now and then during development or debugging.
