Nebula
Pros
- + Free and open source; no vendor sits on your data path
- + Proven at scale — Slack's overlay runs on 50,000+ documented production hosts
- + Modern, non-homegrown crypto: Noise Protocol Framework, Curve25519/P256, AES-256-GCM
- + Certificate-based identity with groups-style firewall rules enforced between peers
- + Direct peer-to-peer tunnels with NAT traversal; lighthouses handle discovery only
Cons
- - You run the PKI: CA key custody, one-year default CA lifetime, certificate signing per node
- - No GUI, no hosted control plane, no SSO in the open-source edition
- - Operationally steeper than WireGuard and much steeper than managed mesh products
- - Overlay IPv6 and mobile client polish lag the desktop experience
- - No support contract or SLA unless you buy the third-party managed offering
Netmaker
Pros
- + Free community tier is unlimited — self-hosted, Apache 2.0, unlimited networks and devices
- + Per-active-connection billing with hourly proration instead of idle seat licenses
- + Peer-to-peer WireGuard mesh keeps traffic off a central bottleneck; relay and egress gateways cover hard NAT cases
- + Deployment choice: fully self-hosted, Netmaker Cloud, or fully managed by their team
- + Dual-stack IPv4/IPv6 networks, private DNS, OAuth, ACLs; SCIM/SIEM/traffic logs on Business
Cons
- - Very small vendor (single-digit headcount, ~$2.8M raised) behind a critical-path product
- - Pricing page mixes current per-connection rates with legacy platform/network fees and a $99/month plan — billing basis is ambiguous
- - Community tier is community-supported only; SLAs are Enterprise-only
- - Self-hosting the server adds operational overhead (upgrades, database, TLS, monitoring)
- - Native mobile meshing not supported — phones connect via gateway and the standard WireGuard app
