When connlib processes DoH queries, we need to pass the server's URL around a lot. In order to bootstrap the HTTP client, we need to extract the host part of this URL and resolve it for IP addresses using the system resolver. A regular URL doesn't necessarily have a host: It could be relative. This creates an error path within our code that _should_ never get hit for DoH URLs as those are always absolute. To avoid this error path, we follow the "parse, don't validate" approach typical among strongly typed languages. We create our own type that can only be constructed from absolute URLs. If we receive a URL from the portal that is not absolute, we already fail at the deserialization step. Using data privacy of the encapsulated url, we can then guarantee that the host-part of the URL is always there and can access it in an infallible way. Given that we are now already parsing the URL to begin with, I've also opted to directly implement an optimisation where we create a fast-path for the 4 known DoH providers that we have which allows us to pass them around and copy them without incurring extra allocations. Finally, this custom type also comes with its own Display/Debug implementation, making the log output a bit easier to read.
A modern alternative to legacy VPNs.
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 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.
See the READMEs in the following directories for more information on building each client:
- macOS / iOS: swift/apple
- Android / ChromeOS: kotlin/android
- Windows / Linux: rust/gui-client
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.
How much does it cost?
We offer flexible per-seat monthly and annual plans for the cloud-managed version of Firezone, with optional invoicing for larger organizations. See our pricing page for more details.
Those experimenting with self-hosting can use Firezone for free without feature or seat limitations, but we can't provide support for self-hosted installations at this time.
