The short version

  • Each has a real cost: Airbyte the self-managed open source Core edition has no SSO or RBAC, no multiple workspaces, no row filtering or encryption, and no monitoring integrations; 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: Airbyte covers Data replication, Nebula covers Certificate carried identity.
  • 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.

Airbyte

  • The self-managed open source Core edition has no SSO or RBAC, no multiple workspaces, no row filtering or encryption, and no monitoring integrations
  • Sync frequency on Core is limited compared with the managed tiers, which offer 15 minute syncs
  • Support on the free tier is community and AI only; premium support requires Pro or Enterprise
  • The free Agents plan stops at 1,000 agent operations a month and pauses capacity until the next month once hit
  • Agent overages are billed per operation at $0.004 to $0.005 once past the plan allowance

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

Airbyte: Is Airbyte free to use?

Yes, Airbyte offers a free tier with 1,000 Agent Operations monthly, single user access, API and MCP support, and community/AI assistance.

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.

Airbyte: What does the Team plan include?

The Team plan costs $299/month and includes 10,000 Agent Operations monthly, parallel workflow execution, multiple users, standard and AI support, with overages charged at $0.005 per AO.

Source
Nebula: Can I run it without Defined Networking?

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

Airbyte: What happens if I exceed my monthly Agent Operations limit?

Overages are charged at $0.004 per AO on the Individual plan and $0.005 per AO on the Team plan, allowing you to exceed your quota as needed.

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.

Airbyte: Does Airbyte offer data replication pricing?

Yes. Airbyte Data Replication starts at $10/month on the Standard plan with 600+ connectors. Pro and Enterprise plans use custom capacity-based pricing with Data Workers and dedicated support.

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.
