If you're on the hunt for an open-source, self-hosted alternative to Microsoft OneNote or EverNote, then you'll want to give OpenNote a look-see. Picture this: a no-fuss, web-based app that brings the power of note-taking and data ownership straight to your own server. That's right, with OpenNote you get to call the shots, your data stays in your hands. OpenNote was built as a progressive web application (PWA) and HTML5 offline app, so you can use it even when your internet is on the fritz. Designed to be lightweight, touch-friendly, and responsive, it’s got the user experience down pat whether you're using a touchscreen or a mouse. One of the standout aspects of OpenNote is its simplicity paired with versatility. Bring Your Own Server (BYOS) and enjoy multi-user support, making it ideal for small teams or solo use. Need to find that note you wrote ages ago? The search function has your back. And the tagging system helps keep things organized without a hitch. Folks worried about being offline will appreciate the CouchDB Sync via PouchDB, which ensures your notes stay updated across devices. Moving folders around is a breeze with drag-and-drop functionality, and renaming or deleting them takes just a click. OpenNote isn't just about what's here and now; there's a roadmap for the future too. Upcoming features look promising with email-to-note functions and mobile apps in the pipeline, giving you even more flexibility. Documentation is well-covered, so you won't be left hanging if you need a hand with installation, upgrading, or theming. And let's not forget the solid open-source licenses under the MIT tag, ensuring you can trust and build upon this project confidently. For those fighting the good fight to support open-source, OpenNote accepts contributions through GitTip, Bitcoin donations, or by simply giving it a like on Alternative To. Check out the demo on their site and dive into the code on GitHub if you're itching to get started. It's a neat package that's got community spirit, functionality, and a dash of future-forward thinking—all wrapped up in one. So, if you're looking to ditch the corporate behemoths for note-taking and want a rugged, reliable alternative that puts control back in your court, OpenNote might just be the ticket.
