  • Proton VPN has unveiled its Spring/Summer 2026 roadmap
  • A new client-side WireGuard codebase promises to boost performance
  • Linux users are getting a new GUI and support for the Stealth protocol

With global censorship and internet restrictions on the rise, Proton VPN has unveiled its Spring/Summer 2026 roadmap, outlining a slew of upgrades designed to make digital privacy more frictionless for its users.

The Swiss-based provider announced that its primary focus for the coming months is to deliver a faster and more reliable experience across all platforms. Proton VPN is completely overhauling its core architecture to keep its spot as a strong contender for the title of best VPN.

"The future of privacy protection isn't just stronger encryption or faster protocols," Antonio Cesarano, Product Lead at Proton VPN, explained in a blog post. "It's making security simple enough that anyone can use it every day."

The centerpiece of the new roadmap is a brand-new client-side WireGuard codebase. This experimental core is designed to build faster apps, deliver best-in-class anti-censorship capabilities, and lay the vital groundwork for post-quantum encryption.

The new architecture is already available for beta testing on Android and Windows, with releases planned for macOS, iOS, iPadOS, and Linux over the coming months.

Linux VPN users are in for a major upgrade, too. Proton is redesigning its Linux GUI app to align with the sleek look and feel found on other platforms. Crucially, the update will introduce long-awaited support for the Stealth protocol, which masks VPN traffic to help users bypass aggressive network blocks and deeply restrictive firewalls.

Windows users aren't being left behind, either. Following a successful rollout on mobile, Proton will soon bring its granular connection preferences to desktop. This will allow Windows users to permanently exclude specific countries, cities, and states from their "Fastest Country" and "Random" connection options.

Finally, Proton VPN for Business is getting an administrative overhaul. IT teams will soon be equipped with advanced web filtering policies, centralized controls to enforce always-on VPN and split tunneling, and a real-time admin dashboard to monitor network alerts.

A busy first half of the year

This forward-looking roadmap follows an incredibly busy first half of the year for the provider, which has been aggressively rolling out app updates and expanding its infrastructure to an impressive 20,000 servers.

Following surges in user demand, Proton VPN expanded its network to cover 145 countries. The addition of servers in highly restrictive regions like Gabon, Haiti, Lebanon, and Nicaragua cemented its position as the top mainstream service for global coverage.

Under the hood, the company pushed hard to modernize its security footprint. It made the bold choice to kill off legacy OpenVPN configs in a push for better security, ultimately ending OpenVPN support on Android entirely.

There have also been major quality-of-life updates across the board. Windows users received a crucial fix allowing them to use three critical features simultaneously, while iOS users enjoyed updates that made securing their iPhones significantly faster.

Meanwhile, a highly requested Android update fixed user frustrations with the Quick Connect feature, proving that Proton is listening closely to community feedback.
