Is Dnote Free and Open Source, and Can You Self-Host It?

Yes. Dnote is free and open source, and it has been since 2017. The project states it "will be always free," and you can inspect the code, contribute improvements, or fork it. Self-hosting is also supported: you can optionally run your own server to sync notes across devices, deployed with Docker or run directly, with no separate database setup required.

What "free and open source" means here

Dnote describes itself as "built in the open," which gives you three concrete options:

• Inspect the code — read how notes, search, and sync actually work before trusting it with your data.
• Contribute improvements — submit changes back to the project.
• Fork it — take the code in your own direction if the project's roadmap doesn't match your needs.

The project's own framing is that "your knowledge belongs to you." That matters for a notes tool, because it means your data isn't locked behind a vendor's continued existence.

Can you self-host it?

Yes — self-hosting is an optional feature, not a requirement. You can use Dnote purely as a local command-line notebook, or add a server when you want notes on more than one machine.

The server is designed to be low-maintenance:

Because the server uses SQLite in a single binary, there's no external database to install, configure, or back up separately. That removes the most common reason people avoid self-hosting small tools.

What you get without the server

The core notebook works entirely on its own:

• Terminal-based capture — save commands, snippets, and insights without leaving the terminal.
• Full-text search — search all notes instantly instead of scrolling through shell history.
• Bring your own editor — works with your preferred editor, terminal-based or GUI.
• SQLite format — one file contains everything, so you can back it up to any storage, query it with standard tools, or migrate it easily.
• Single binary — no dependencies and no package managers required; download and run.
• Cross-platform — binaries for macOS, Linux, FreeBSD, and Windows, installable via Homebrew or direct download.

How to decide

Self-host if you want notes synced across multiple devices but don't want them passing through someone else's infrastructure, and you're comfortable running a binary or a Docker container.

Skip the server if you only use one machine. The local notebook, full-text search, and SQLite file already cover capture and retrieval, and you avoid running any service at all.

Consider a fork or contribution if you need behavior the project doesn't offer — the open-source license and public codebase make that a legitimate path rather than a workaround.

One practical note: because everything lives in a single SQLite file, your backup strategy is simply copying that file. If you self-host, the same applies to the server's data — there's no database cluster to snapshot.
