| Free tier | 'Nebula is a scalable overlay networking tool with a focus on performance, simplicity and security. It lets you seamlessly connect computers anywhere in the network.' Self-hosted; no quota. unit unlimited; metered on none |
|---|
| Price | USD 0 |
|---|
| Binding | none Nothing meters bytes and nothing publishes a port, so no constraint fires at 1 TiB/month because the traffic cannot leave the overlay. |
|---|
| Identity | anonymous self-hosted; membership is a signed certificate from the operator's CA |
|---|
| Egress | No allowance: there is no vendor and no hosted service.; ingress: none free allowance: none published |
|---|
| Interface | cli config files plus a certificate authority the operator runs |
|---|
| Tooling | nebula and nebula-cert binaries |
|---|
| Composes with | a private overlay that composes with a public ingress and adds none |
|---|
| Reliability | self-operated; certificate issuance and lighthouse uptime are local work |
|---|
| Notes | Included because the supplied list names it and because a reader will confuse it with a WireGuard tool. |
|---|
| Evidence note | inferred The overlay claim is quoted; the 'no ingress' conclusion is inferred from the description, because a feature that does not exist has no page saying so. Reading the lighthouse documentation would raise this to documented. |

| wg path | unknown |

| wg detail | The repository describes 'encryption, security groups, certificates, and tunneling' without naming WireGuard; no protocol page was read, so whether the transport can carry a WireGuard datagram is open. |
|---|
| ingress | none |
|---|
| volume stated | No allowance: there is no vendor and no hosted service. |
|---|
| bytes transit | overlay-only |
|---|
| transit note | peers relay through lighthouses only to find each other; payload goes peer to peer |
