StartOS v0.4.0

v0.4.0 is a complete rewrite of StartOS. After six years of building, we believe we have arrived at the correct architecture and foundation to deliver on the promise of sovereign computing.

⚠️ Before You Update

Everyone is welcome to participate in the public beta! However, the only way to update is by following the 0.4.0 Update Guide precisely. This is a sensitive update between two essentially distinct operating systems — skipping steps or improvising can result in data loss.

👉 Read the full update guide before proceeding

If anything goes wrong, stop and contact support — do not attempt to troubleshoot on your own.

Highlights

• Redesigned UI — faster, more intuitive, mobile-friendly, with a real-time system metrics dashboard
• Completely new networking stack — LAN port forwarding, Wireguard VPN gateways, private and public domains (clearnet), Let's Encrypt, built-in DNS, and Tor as an optional plugin
• StartTunnel — free, open-source reverse tunnel to expose services on a public domain without revealing your home IP
• LXC container runtime — replacing Docker/Podman with a reliable, nested container architecture supporting hardware acceleration and multi-container setups
• Improved backups — differential backups, cross-server restore, and a new FUSE module for cross-platform reliability
• Internationalization — multiple languages and keyboard layouts for StartOS and services
• TypeScript SDK — build and ship a StartOS package in minutes
• New S9PK format — signature verification, partial downloads, and multi-architecture support
• SMTP notifications — email alerts from StartOS and services via Gmail, SES, or any SMTP provider

Important

Previous backups are incompatible with v0.4.0. After updating, immediately update all services and create a fresh backup.

What's Changed

• feat(tunnel): update design according to Start9 guidelines by @waterplea in #3185
• fix: backup reliability (rsync + cifs) and assorted fixes by @dr-bonez in #3184
