Deployment Inquiries, Commercial Licensing & SLA

Parch Linux is an open-source, community-driven project developed freely for general users and enthusiasts. Apadana is the commercial enterprise edition built on the exact same technical foundation—Parch Immutable architecture—but tailored specifically for corporate and institutional requirements. In other words, Parch serves as the shared technical core, while Apadana is the enterprise product layered on top with dedicated focus on stability, SLA support, and organizational policies.

The technical core of Apadana is rooted in free and open-source software, but Apadana itself is offered as a commercial enterprise product backed by support contracts, maintenance services, and enterprise SLAs. Details on pricing tiers and organizational packaging will be announced prior to final release.

No. Apadana is a completely independent, commercial project engineered and maintained by the Parch Linux team, with no affiliation to government entities.

Unbreakable stability is the primary design goal of Apadana. The immutable architecture ensures updates are staged atomically, and in the rare event of an issue, reverting to the prior verified state takes mere seconds at boot. This approach drastically reduces the post-update instability common in traditional package-managed distributions.

This roadmap is actively being drafted. Comprehensive migration frameworks and technical compatibility strategies for Windows-centric enterprise environments will be announced soon.

An Immutable operating system is one where the core root files and base system configurations cannot be directly modified after installation, but are instead managed as a verified, unified image. Application installation and user customizations occur strictly inside isolated layers like Flatpak sandboxes and containerized runtimes without touching core OS files. This eliminates configuration drift over time and makes all updates deterministic, predictable, and reversible.
