Open Line

South Africa mixed-stack open-source retainers for Linux, Unix and private AI.

Don’t buy the OS. Buy the estate. One rand retainer. Mixed distros first-class. Out-of-bundle products on the same SLA — nginx, Postgres, WordPress, Docker, Kubernetes, Ollama, Pi fleets. Not a vendor SKU. The stack you actually run.

ZAR · SAST

No USD licence games. Hours included so scope does not melt.

Named engineer

On the invoice

WhatsApp plus ticket. The person who quoted you is the person who answers.

Mixed stack

First-class

Debian, Ubuntu, Raspberry Pi OS, Rocky, Alma, Unix — not “best effort”.

One ticket

Apps included

Out-of-bundle products on the same SLA, not a science project.

What the market does vs what Open Line is

What the market does

Canonical: Ubuntu only, USD, up to ~$3,400/server/year for 24/7. Red Hat / SUSE: sockets and SKUs. SA MSPs: R400–R1,000 per Windows user. Patch vendors: cheap CVE streams, nobody on the incident.

What Open Line is

Estate retainer, not per-user, not per-socket. Debian, Ubuntu, Pi OS, Rocky, Alma, Unix — first-class. Out-of-bundle apps on the same ticket. Private AI and edge fleets as add-on SKUs.

We do not replace Ubuntu Pro, TuxCare or Red Hat indemnification. Compliance estates bring their own patch stream. We operate the mixed stack and answer the pager.

  2. Pick Bench, Workshop or Line — tick add-ons. Sign month-to-month or 12 months.
  3. Operate — patch window, backup verify, ticket + WhatsApp, incident hours against the cap.
