During the latest relay outage, we failed to send heartbeats to the portal because we were busy-looping and never got to handle messages or timers for the portal. To mitigate this or similar bugs, we update an `Instant` every time we send a heartbeat to the portal. In case we are actually network-partitioned, this will cause the health-check to fail after 15 minutes. This value is the same as the partition timeout for the portal connection itself[^1]. Very likely, we will never see a relay being shutdown because of a failing health check in this case as it would have already shut itself down. An exception to this are bugs in the eventloop where we fail to interact with the portal at all. Resolves: #4510. [^1]: Previously, this was unlimited.
A modern alternative to legacy VPNs.
Note: 🚧 The main branch is undergoing major restructuring in preparation
for the release of Firezone 1.0 🚧.

you're looking for Firezone 0.7.

Overview
Firezone is an open source platform to securely manage remote access for any-sized organization. Unlike most VPNs, Firezone takes a granular, least-privileged approach to access management with group-based policies that control access to individual applications, entire subnets, and everything in between.
Features
Firezone is:
- Fast: Built on WireGuard® to be 3-4 times faster than OpenVPN.
- Scalable: Deploy two or more gateways for automatic load balancing and failover.
- Private: Peer-to-peer, end-to-end encrypted tunnels prevent packets from routing through our infrastructure.
- Secure: Zero attack surface thanks to Firezone's holepunching tech which establishes tunnels on-the-fly at the time of access.
- Open: Our entire product is open-source, allowing anyone to audit the codebase.
- Flexible: Authenticate users via email, Google Workspace, Okta, Entra ID, or OIDC and sync users and groups automatically.
- Simple: Deploy gateways and configure access in minutes with a snappy admin UI.
Firezone is not:
- A tool for creating bi-directional mesh networks
- A full-featured router or firewall
- An IPSec or OpenVPN server

Frequently asked questions (FAQ)
Can I self-host Firezone?
Our license won't stop you from self-hosting the entire Firezone product top to bottom, but our internal APIs are changing rapidly so we can't meaningfully support self-hosting Firezone in production at this time.
If you're feeling especially adventurous and want to self-host Firezone for educational or hobby purposes, follow the instructions to spin up a local development environment in CONTRIBUTING.md.
The clients can be built from their respective directories.
The latest published clients (on App Stores and on
releases) are only guaranteed
to work with the managed version of Firezone and may not work with a self-hosted
portal built from this repository. This is because Apple and Google can
sometimes delay updates to their app stores, and so the latest published version
may not be compatible with the tip of main from this repository.
Therefore, if you're experimenting with self-hosting Firezone, you will probably want to use clients you build and distribute yourself as well.
How long will 0.7 be supported until?
Firezone 0.7 is currently end-of-life and has stopped receiving updates as of
January 31st, 2024. It will continue to be available indefinitely from the
legacy branch of this repo under the Apache 2.0 license.
