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.; Nitric smaller community compared to Terraform or Pulumi
  • They diverge on capability: Nebula covers Certificate carried identity, Nitric covers Multi-language support.
  • 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.

Nitric

  • Smaller community compared to Terraform or Pulumi
  • Limited third-party provider plugins compared to dedicated IAC tools
  • Documentation could be more comprehensive

Questions people ask

Is Nebula or Nitric better?
Neither clearly leads. Nebula starts at Free and Nitric at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Nebula or Nitric?
Nebula starts at Free and Nitric at Free.
Does Nebula or Nitric run on more platforms?
Nebula runs on Linux, macOS, Windows, iOS, Android, FreeBSD. Nitric runs on AWS, Azure, GCP, Kubernetes.
Can I use Nebula for free?
Both have a free tier, so you can try either at no cost before committing.
What is Nebula best used for?
Nebula is most often used for flattening a network across several clouds and datacentres without vpc peering or route tables, very large fleets where a central policy service on the connection path is unacceptable, environments that already run an internal certificate authority and want the network to use it, replacing per host iptables rules with policy written against roles that follow the host. Of those, flattening a network across several clouds and datacentres without vpc peering or route tables and very large fleets where a central policy service on the connection path is unacceptable are not what Nitric is typically brought in for.
What can Nebula do that Nitric cannot?
Nebula covers Certificate carried identity, Group based host firewall, Lighthouse discovery, Noise protocol encryption. Nitric covers Multi-language support, Common resource abstractions, Local development, Multi-cloud deployment.

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.

Nitric: Is Nitric free?

Yes, Nitric is an open-source framework. Costs only apply when deploying to cloud providers like AWS, Azure, or GCP.

Source
Nebula: Can I run it without Defined Networking?

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

Nitric: Can I switch cloud providers?

Yes, Nitric lets you write code once and deploy to AWS, Azure, GCP, or Kubernetes without modification.

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.

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.
