Alternatives to OpenZiti
Open-source zero trust overlay network with app-embeddable SDKs
OpenZiti ranks #6 of 11 in Mesh VPNs, with an Alt Score of 78. It is licensed under Apache-2.0, open source with paid hosting from Free and available on Windows, macOS, Linux, iOS and Android. 11 of 12 checklist rows are verified against a public source.
OpenZiti is an open-source, programmable zero-trust networking platform stewarded by NetFoundry that builds an overlay fabric of routers and identities instead of exposing listening ports on hosts. Teams use it to connect devices, services, and private networks with policy-based authorization and SSO/OIDC integration, and developers can embed zero-trust connectivity directly into applications via its SDKs. It's positioned as a more application-aware alternative to WireGuard-mesh tools like Tailscale and Headscale.
Developers, platform teams, and organizations that need to replace traditional VPN or firewall-based remote access with identity-based access to internal services, APIs, IoT devices, and non-human workloads across on-prem, multi-cloud, and hybrid environments.
A self-hostable, open-source (Apache-2.0) overlay network consisting of a controller, a mesh of edge routers, tunneler apps for Linux, Windows, macOS, iOS, and Android, and SDKs (Go, C, Java/Kotlin, Swift, Node.js, C#, Python) for embedding zero-trust connectivity directly into applications. NetFoundry, the project's sponsor, separately sells a managed hosted version of the same technology.
Every user, service, or device is issued a cryptographic (x509) identity, and connections are mutually authenticated (mTLS) and authorized against service and edge-router policies before any traffic flows. Services and private routers make only outbound connections to the mesh fabric, so they have no open listening ports ("dark" services), and authorized traffic is routed end-to-end through the overlay rather than by IP address.

Firezone is an open-source, self-hostable remote access platform built on WireGuard that creates direct, encrypted peer connections between users and internal resources through lightweight gateways.
Headscale is an open-source coordination/control server that is API-compatible with the official Tailscale client apps, letting teams self-host their own control plane while keeping the same mobile an.
Defguard is an open-source, Rust-built WireGuard VPN manager that adds multi-factor authentication, an identity/SSO gateway, and a web UI for managing peers, gateways, and access policies.
Nebula is an open-source peer-to-peer mesh networking tool originally built and battle-tested internally at Slack before being open-sourced.
innernet is an open-source tool built by Tonari that wraps raw WireGuard to automate peer key exchange and IP address allocation for private mesh networks, similar in goal to Nebula and early Tailscal.
