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.; Penpot smaller user base and community compared to Figma means fewer templates and resources
  • They diverge on capability: Nebula covers Certificate carried identity, Penpot covers Vector editing.
  • 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.

Penpot

  • Smaller user base and community compared to Figma means fewer templates and resources
  • Self-hosting requires Linux server and Docker knowledge for technical setup
  • Real-time collaboration features may have performance issues with very large design files

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.

Penpot: Is Penpot really free?

Yes. Penpot is completely free with no feature gates. The open-source version can be self-hosted on your own infrastructure for zero cost beyond server expenses.

Nebula: Can I run it without Defined Networking?

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

Penpot: Can I self-host Penpot?

Yes. Penpot can be self-hosted on your own infrastructure with no licensing costs. Organizations with specific privacy or governance needs can run Penpot on their own servers.

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.

Penpot: What are the paid plans if I use Penpot cloud?

Penpot's cloud service offers a free tier, Unlimited plan at $7 per user per month for professionals and medium teams, and Enterprise starting at $950 per month for larger organizations.

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.

Penpot: What platforms does Penpot support?

Penpot runs in the browser, so it works on Windows, Mac, Linux, and any OS with a web browser. No platform-specific downloads required.
