# Alternatives to OpenZiti

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.

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.

## Overview

- **Who it's for**: 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.
- **What you get**: 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.
- **How it works**: 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.
