Short answer: the connlib refactor makes the internals cleaner, but your deployment decision from two weeks ago still holds.

What Actually Changed

Still, stars barely budged — 8,707 now against ~8,700 two weeks ago. That’s not a warning sign for a mature infrastructure tool. Firezone isn’t a hype project riding a viral launch. And it’s a steady enterprise tool with 10,400+ total commits, with a development cadence that reflects that: consistent, not explosive. The headless client 1.5.10 also added Windows support alongside Linux x86_64, aarch64, and armv7 builds — a useful expansion if your team runs Gateways on mixed hardware.

The Connlib Refactor: What It Actually Means

PR #13908, authored by core maintainer Thomas Eizinger and merged today (June 29), moves all pre-connection packet buffering out of snownet and boringtun into a single client-side location. In practice, this means the client now holds packets per connection until the WireGuard tunnel establishes, then flushes them.

I traced through the diff to understand the practical effect. Before the refactor, buffering was split across two modules — snownet kept an ip_buffer, and boringtun had its own internal queue. After, there’s exactly one buffer location in the client layer, and snownet only calls encapsulate_data_at without managing its own queue.

This is invisible to end users. Sure, you won’t see faster connections or a different admin panel. But for anyone running Firezone at scale — think 50+ connected devices across multiple Gateways — this means more predictable memory usage during connection establishment and easier debugging when something goes wrong. Still, the team noted the wg_buffer for ICE handshake responses is being addressed separately, so the cleanup isn’t finished yet.

Does This Change the Recommendation?

No. And that’s not a bad thing.

The connlib refactor is a quality improvement, not a feature milestone. It doesn’t add SSO providers, change the pricing model, or introduce multi-region Gateway support. And the original review’s verdict still stands: Firezone is the best open-source zero-trust platform for teams that want full control and don’t mind DevOps work.

But I’d argue this refactor is actually a positive signal. A team that spends engineering cycles cleaning up packet buffering instead of chasing feature-count growth is a team thinking about long-term reliability. For production deployments, that matters more than another shiny dashboard widget.

Bottom Line

Still, Firezone is alive, actively maintained, and getting cleaner under the hood. The connlib refactor won’t change your buying decision, but it should reassure anyone who picked Firezone based on the June review that the project isn’t coasting. If you’re still evaluating, the self-hosted Starter tier (free, 6 users) on a $6 VPS remains the best way to test.

For comparison, Tailscale’s mesh approach targets a different use case — zero-config for teams that don’t want to manage Gateways. Firezone’s edge is full control, and this refactor reinforces that strength.

For deployment, the original Docker Compose setup on a DigitalOcean or Vultr instance still applies — the refactor doesn’t change the architecture.
