The short version

  • Each has a real cost: Chef priced per node per year, at $59 on Business and $189 on Enterprise, so cost scales with fleet size rather than with team size; 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.
  • They diverge on capability: Chef covers Recipes, Nebula covers Certificate carried identity.
  • Prices and features above were last checked on 31 August 2026.

Chef

  • Enforcing compliance and audit policy on managed nodesnot Nebula

Nebula

  • Flattening a network across several clouds and datacentres without VPC peering or route tablesnot Chef

  • Environments that already run an internal certificate authority and want the network to use itnot Chef
  • Replacing per host iptables rules with policy written against roles that follow the hostnot Chef

Where each one falls short

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

Chef

  • Priced per node per year, at $59 on Business and $189 on Enterprise, so cost scales with fleet size rather than with team size
  • Tripling the price between the two published tiers puts compliance and audit features well above basic automation
  • Enterprise Plus and every self managed deployment are custom quoted with no published price

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.

Answered from the vendors’ own pages

Chef: How much does Chef cost?

Chef does not publish pricing on its website. The company offers a free trial and directs interested customers to request a demo or contact their sales team for pricing details.

Source
Nebula: Does it use WireGuard?

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

Chef: Is there a free trial available?

Yes, Chef offers a free trial to interested users, allowing them to evaluate the platform before purchasing.

Source
Nebula: Can I run it without Defined Networking?

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

Chef: What deployment options are available?

Chef is available as SaaS (cloud-hosted), on-premises, and through cloud marketplaces like AWS and Azure, but specific pricing for each deployment model is not published.

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.

Chef: How do I get pricing information?

Sign up for the free trial or request a demo through Chef's website to speak with their sales team about pricing.

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.
