What is Arcline OS?

A Debian-derived OS that doesn't
make you start from scratch.

Debian gives you a rock-solid base. Arcline OS hardens it, layers on a full observability stack, and ships with pre-configured container infrastructure. No telemetry. No snap store. No cloud integration. Just a secure, auditable OS that respects your hardware.

Secure by default

Hardened Linux kernel with seccomp, AppArmor profiles, and restrictive nftables firewall. You opt in to exposure — never out.

Privacy-first

Zero telemetry. Zero analytics. Zero cloud integration. No network calls you didn't initiate.

btrfs-native

btrfs root with subvolume snapshots, transparent compression, and boot-to-snapshot rollback — not bolted on, built in.

Developer-ready

Go, Rust, Python, Node.js toolchains pre-configured. Git, Make, LLVM/Clang included. Start building immediately.

Infrastructure-aware

Prometheus node_exporter, Grafana dashboards, and Loki log aggregation — pre-configured out of the box.

Fully documented

Every feature and tool includes offline man pages and a hardening guide. You own the system — and you understand it.

What's Included

Production-ready from first boot.

Arcline OS layers pre-configured infrastructure tooling on top of a hardened Debian base. Everything is documented, auditable, and yours.

The Toolchain

11 Go tools. Built in production.
Yours to use.

Every Arcline tool was built to solve real infrastructure problems. They run in production at Arcline IT. Now they ship with Arcline OS.

arcline-uptime HTTP, TCP, TLS, DNS monitoring with Prometheus metrics export
arcline-check CDN and transparency auditor — verifies sites aren't leaking data
arcline-audit Full site health scanner — SSL, headers, performance, accessibility
arcline-dns DNS propagation checker across multiple resolvers
arcline-vault Encrypted secrets store with REST API and CLI
arcline-email Self-hosted SMTP/IMAP stack — OpenSMTPD + Dovecot + Rspamd
arcline-migrate cPanel and Plesk to Arcline migration tool
arcline-billing Stripe-powered subscription management
arcline-portal Customer dashboard with SSL monitoring and ticketing
arcline-website Go HTTP server powering arcline.it
arcline-status Static status page generator
Why Arcline OS?

No major Linux distro ships
pre-hardened for production.

Debian gives you the packages. Arcline OS assembles them into a finished system. A privacy-first, zero-telemetry operating system with built-in monitoring, auditing, and security — configured the way you'd do it yourself, if you had the weekend.

Ubuntu Server
Great ecosystem and hardware support — but Snap packages and cloud integration are baked in by default.
Fedora Server
Cutting-edge kernel and tooling — but rapid release cycles mean more churn on production machines.
Alpine Linux
Minimal and musl-based — ideal for containers, but limited as a full-featured server workstation.
Arcline OS
Hardened Debian base. Pre-configured toolchain. Built-in observability. Zero telemetry. Ready to deploy.
