The short version

  • Each has a real cost: Nebula the open source project has no user interface, no enrolment workflow and no revocation service, so certificate issuing, distribution and expiry become scripts you write and then have to keep working.; Notepad++ windows-only, with no official native macOS or Linux build.
  • They diverge on capability: Nebula covers Certificate carried identity, Notepad++ covers Syntax Highlighting.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Nebula

  • The open source project has no user interface, no enrolment workflow and no revocation service, so certificate issuing, distribution and expiry become scripts you write and then have to keep working.
  • Revoking a compromised host means distributing a blocklist entry to every other host and reloading them, which is a fleet wide operation rather than a click, and easy to get wrong under pressure.
  • Changing a host group membership means reissuing and redeploying its certificate, so policy changes are a deployment rather than a configuration edit.
  • There is no identity provider integration or single sign on in the open source version, so it maps well to servers and badly to a fleet of user laptops.
  • NAT traversal is best effort and hosts behind symmetric NAT need a relay configured deliberately, so connectivity failures show up as intermittent rather than immediate and are awkward to diagnose.

Notepad++

  • Windows-only, with no official native macOS or Linux build.
  • Lacks built-in debugging or project/build management found in full IDEs.
  • Plugin quality and maintenance varies since they are community-contributed.
  • No built-in version control integration beyond what plugins provide.

Answered from the vendors’ own pages

Nebula: Does it use WireGuard?

No. Nebula predates the common WireGuard mesh tools and uses the Noise protocol framework with its own certificate format.

Notepad++: Is Notepad++ free?

Yes, Notepad++ is free and open-source software distributed under the GNU General Public License, with no paid tiers.

Source
Nebula: Can I run it without Defined Networking?

Yes, entirely. Defined Networking sells the control plane conveniences, not the network itself.

Notepad++: What license does Notepad++ use?

Notepad++ is licensed under the GNU General Public License v2.0 (GPLv2), meaning its source code is freely available and modifiable under GPL terms.

Source
Nebula: How do I revoke a host?

Add its certificate fingerprint to the blocklist in the configuration of the other hosts and reload them. There is no online revocation check.

Notepad++: Which operating systems does Notepad++ support?

Notepad++ runs exclusively on Microsoft Windows; there is no official native build for macOS or Linux.

Source
Nebula: Is it a good fit for laptops?

Less so than the identity provider based tools. There is no single sign on, so every laptop needs a certificate issued and renewed by whatever process you build.

Notepad++: How do I install plugins in Notepad++?

Plugins are installed and managed through the built-in Plugins Admin (plugin manager), which lists community plugins available for download and update.

Source
Notepad++: Where can I get help or documentation for Notepad++?

Official documentation is at the User Manual site, and community support is available through the Notepad++ community forum and GitHub issue tracker.
