In a world overflowing with note-taking applications, finding one tailored specifically to the needs of developers and programmers can feel like searching for a needle in a haystack. Enter Boostnote an open-source, markdown-based note-taking application built from the ground up with developers in mind.
Whether you are a solo coder juggling multiple projects, a software engineer managing complex documentation, or a tech-savvy professional looking for a distraction-free writing environment, Boostnote promises a streamlined and powerful experience. But what exactly is Boostnote, and how does it work? In this comprehensive guide, we will break down everything you need to know — from its core features and architecture to its strengths, weaknesses, and how it compares to the competition.
What is Boostnote?
Boostnote is a free, open-source note-taking application designed primarily for programmers and developers. It was created by the Japanese development team at BoostIO and first released publicly around 2016. The application is built using Electron, which means it runs as a cross-platform desktop app on Windows, macOS, and Linux — three operating systems commonly used in software development environments.
Unlike general-purpose note-taking tools such as Evernote or Microsoft OneNote, Boostnote places a heavy emphasis on code-centric workflows. It supports syntax highlighting for over 100 programming languages, making it a go-to tool for writing and storing code snippets, documentation, API references, and technical notes.
At its core, Boostnote operates on the principle of simplicity and openness. The codebase is available on GitHub, meaning any developer can inspect the source code, contribute to its development, or fork it for custom use. This transparency has helped Boostnote earn a loyal following in the open-source and developer communities.
A Brief History of Boostnote
Boostnote was originally launched as a desktop-only note-taking tool targeting developers. In its early days, it gained rapid popularity on GitHub, amassing tens of thousands of stars and establishing itself as one of the top developer tools in the note-taking space.
Over the years, BoostIO (the company behind Boostnote) evolved the product significantly. The team eventually transitioned from the original Boostnote to Boost Note — a more modern, cloud-enabled platform with team collaboration features. However, the legacy version of Boostnote remains available and is still actively used by many developers who prefer a fully offline, local-storage-based experience.
This evolution is important to understand because when people refer to “Boostnote” today, they may mean one of two things: the original legacy desktop app or the newer cloud-based Boost Note platform. This article covers both, with a focus on how the tool works in practice.
Key Features of Boostnote
Understanding what makes Boostnote stand out requires a close look at its features. Here is a detailed breakdown:
1. Markdown Support
Boostnote is built around Markdown — a lightweight markup language that uses plain text formatting syntax. When you write in Boostnote, you type in Markdown on one side of the screen and see a rendered preview on the other. This split-view or toggle-view system makes it easy to format notes without clicking through menus or toolbars.
Markdown support in Boostnote extends to headings, bold/italic text, blockquotes, horizontal rules, inline code, and code blocks — all essential formatting elements for technical documentation.
2. Code Snippet Notes with Syntax Highlighting
One of Boostnote’s most celebrated features is its dedicated code snippet note type. Rather than embedding code blocks within a regular Markdown note, you can create a note that is entirely a code snippet. Boostnote supports syntax highlighting for over 100 programming languages including Python, JavaScript, TypeScript, Java, Ruby, Go, C++, Rust, and many more.
For developers who rely on saved code snippets as part of their workflow, this feature is invaluable. You can organize your snippets by language, tag them, and retrieve them quickly when needed.
3. Offline-First Architecture
Unlike many modern note-taking tools that require internet connectivity, the legacy version of Boostnote is entirely offline-first. All notes are stored locally on your machine in a designated folder. There is no mandatory account creation, no subscription, and no cloud dependency.
This is a significant advantage for developers who work in secure environments, travel frequently, or simply prefer to have full ownership and control over their data.
4. Cross-Platform Compatibility
Boostnote is available on Windows, macOS, and Linux — the three dominant operating systems in the developer ecosystem. This cross-platform availability means you can use Boostnote on your work machine, personal laptop, or Linux server workstation without losing access to your notes.
The application is built with Electron and React, which allows it to maintain a consistent user interface across all platforms while taking advantage of native system integrations.
5. Folder and Tag Organization
Boostnote allows you to organize notes into storage folders and tag them for easy retrieval. You can create multiple storage locations — for example, one for a work project, one for personal notes, and one for a side project. Within each storage, notes can be further sorted using tags.
This flexible organizational structure means Boostnote adapts to your personal workflow rather than forcing you into a rigid hierarchical system.
6. Search Functionality
Boostnote includes a full-text search feature that allows you to search across all your notes simultaneously. This is particularly useful when you have hundreds of notes and need to find a specific function, concept, or snippet quickly.
The search function works locally, meaning results appear instantly without any network latency — another benefit of the offline-first architecture.
7. Themes and Customization
Boostnote offers both light and dark modes, along with customization options for font size, editor layout, and code theme. For developers who spend hours staring at a screen, the ability to switch between themes and adjust typography is a quality-of-life feature that matters.
8. Export Options
Notes in Boostnote can be exported in Markdown (.md) and HTML formats. This makes it easy to move notes to other platforms, publish them as web content, or share documentation with teammates who may not use Boostnote.
How Does Boostnote Work?
Now that we know what Boostnote offers, let us look at how it actually works under the hood and in practice.
Installation
Getting started with Boostnote is straightforward. You download the installer for your operating system from the official Boostnote website or its GitHub repository. The installation process is standard for an Electron app — run the installer, follow the prompts, and the application launches within minutes.
No account creation is required for the legacy desktop version.
Creating Your First Storage
When you first open Boostnote, you are prompted to create a storage — essentially a local folder on your hard drive where all your notes will be saved. You can create multiple storage locations to separate different contexts (e.g., Work, Personal, Learning).
Each storage acts as an independent workspace with its own set of folders and notes.
Note Types in Boostnote
Boostnote supports two primary note types:
Markdown Notes — These are traditional text-based notes written in Markdown syntax. You can use them for documentation, meeting notes, checklists, project plans, and any content that benefits from formatted text.
Code Snippet Notes — These are purpose-built for storing code. When creating a snippet note, you select the programming language and the editor switches to a syntax-highlighted code editor mode. Snippet notes can contain multiple code blocks within a single note.
Editing and Previewing
The Boostnote editor operates in a split-screen mode by default, showing your Markdown source on the left and a real-time rendered preview on the right. You can also toggle to a full-screen writing mode or a preview-only mode depending on your preference.
For code snippet notes, the editor provides a full-screen code editing experience with language-specific syntax highlighting.
Saving and Syncing
In the legacy desktop version, notes are saved automatically to the local storage folder you defined during setup. The notes are stored as .cson files (CoffeeScript Object Notation), which are human-readable and can be version-controlled using Git if you wish.
To sync notes across devices in the legacy version, you can place your Boostnote storage folder inside a cloud storage service such as Dropbox, Google Drive, or iCloud Drive. This workaround effectively creates cross-device sync without requiring any built-in cloud functionality.
The newer Boost Note platform, by contrast, handles sync natively through its own cloud infrastructure and supports real-time collaboration between team members.
Boostnote vs. Other Note-Taking Apps
To understand Boostnote’s value, it helps to compare it to alternative tools:
Boostnote vs. Notion
Notion is an all-in-one workspace with databases, kanban boards, wikis, and notes. It is powerful but complex and requires an internet connection. Boostnote is simpler, faster, and works offline — making it a better fit for developers who want a no-frills, code-centric tool without the overhead of Notion’s feature set.
Boostnote vs. Obsidian
Obsidian is a Markdown-based knowledge management tool with an advanced graph view and plugin ecosystem. It has a steeper learning curve but more power for building interconnected knowledge bases. Boostnote is more accessible and developer-focused, with built-in code snippet support that Obsidian does not offer natively.
Boostnote vs. Joplin
Joplin is another open-source Markdown note-taking app with sync capabilities via various cloud providers. Both tools are similar in philosophy, but Boostnote wins on developer-specific features like multi-language code snippet support and its code editor interface.
Boostnote vs. VS Code Notebooks
Some developers use VS Code with Jupyter-style notebooks for notes. While this works well for Python-centric workflows, Boostnote is more versatile as a general note-taking environment that is not tied to a specific language or execution environment.

Getting the Most Out of Boostnote
Here are some practical tips to maximize your Boostnote experience:
Use tags consistently. Develop a personal tagging system from the start. Tags like #javascript, #api, #regex, or #bash make retrieval far more efficient as your note library grows.
Sync via Dropbox or Google Drive. Place your Boostnote storage folder inside a cloud sync folder to access your notes across multiple computers without any additional setup.
Use Git for version history. Since Boostnote notes are stored as local files, you can initialize a Git repository in your storage folder to maintain a full history of changes — perfect for documentation projects.
Create a snippet library. Dedicate one storage folder entirely to reusable code snippets. Over time, this becomes an invaluable personal reference library.
Keyboard shortcuts. Learn Boostnote’s keyboard shortcuts to navigate between notes, create new notes, and switch views without touching the mouse.
