Obsidian is described as 'Note-taking app that lets you create a personal knowledge graph with ease. It is designed for non-linear thinking and allows you to easily link your notes together wiki-style' and is a leading Note-taking tool in the office & productivity category. There are more than 100 alternatives to Obsidian for a variety of platforms, including Mac, Web-based, Windows, Linux and Android apps. The best Obsidian alternative is Logseq, which is both free and Open Source. Other great apps like Obsidian are Zettlr, Joplin, sNotes – Students Notes and Anytype.
The original trilium is transfered to this repo by its owner and the app continues to develop here as stated here: https://github.com/TriliumNext/Trilium
Powerful online word processor with real-time collaboration, document conversion from Word, extensive formatting options, revision history, and multilingual capabilities, all integrated within the Google Drive ecosystem, accessible through any internet-connected device.
Hierarchical note-taking software that is free, open-source, cross-platform. Features include rich text, syntax highlighting, multi-level lists, embedded files, customizable interface, code execution, PDF export, spell check, images & tables, and comprehensive project management support.
Kind of the same thing? More of a hierarchical note taker, but it runs locally, is super stable, and keeps you organized, so if you don't need all the bells and whistles, this'll get the job done.
Its not an alternate to Obsidian which is mainly giving you advanced Markdown format, while CherryTree his simply its own format.
However, its an awesome notes taking software. I really like its Tree structured interface for arranging your notes.
Made by the company behind WordPress, Simplenote enables users to take notes, lists, and ideas. These notes are stored on the cloud and are accessible across multiple devices.
Simplenote is love. You must try it once. I have SimpleNote installed on my Mac, Windows, Linux, Android and iPad. It works on all browsers and all operating systems. It is so easy to take notes and have them sync across all devices and web. It is so easy to quickly get to your notes. I can't live without simplenote as I have so much dependency on this simple tool. Simplenote really makes it simpler to organize 'note taking' task.
The most prominent feature of Obsidian is bi-directional linking between notes. Simplenote is more akin to sticky notes; they aren't really similar at all.
Its too simple and is focused on simplicity unlike obsiidian
Open-source, privacy-focused workspace combining note-taking, project and task management, Kanban board, interactive whiteboard, Pomodoro timer, Markdown support, offline access, real-time team collaboration with @mentions, goal tracking, subtasks, and customizable features.
CryptPad is a private-by-design alternative to popular office tools and cloud services. All the content stored on CryptPad is encrypted before being sent, which means nobody can access your data unless you give them the keys.
SiYuan is a desktop Markdown Block-Reference and Bidirectional-Link note-taking application. Support fine-grained block-level reference and Markdown WYSIWYG.
I honestly think SiYuan is the closest to Obisdian as an alternative compared to all other apps.
WYSIWYG is far more important than I thought. Besides, the data in SiYuan is .json, which allows better redering-performance and Notion-like typesetting.
WYSIWYG, better rendering performance
GNU Emacs is an extensible, customizable text editor—and more. At its core is an interpreter for Emacs Lisp, a dialect of the Lisp programming language with extensions to support text editing. The features of GNU Emacs include:
Plain text notepad with markdown support and todo list manager for Linux, Mac OS X and Windows, that works together with the notes application of ownCloud.
Pretty similar concept, both deal with plain .md files, both render in real time, both have automatically-generated TOCs, etc., but QOwnNotes is Free Software, no EULA non-sense, you have a tool without restrictions.
Docmost is an open-source collaborative wiki and documentation software. It is an open-source alternative to Confluence and Notion.
Dendron is an open-source, local-first, markdown-based, note-taking tool built on top of VSCode. It supports all the usual features you would expect like tagging, backlinks, a graph view, split panes, and so forth.
Still local notes, but way more full-featured since it uses VS Code as the editor and embraces heirarchies so your notes don't get so unwieldly.
Offline in-device task manager and note app featuring smart creation, advanced organization, calendar and list views, Markdown notes, secure SHA-256 encryption, Material You theming, multiple color themes, no tracking or ads, and import/export for total ownership.

This is a very good candidate to be the Obsidian alternate. However, it has a steep learning curve.
