SCTR is a Rust/systemd hosting control plane for long-running non-PHP applications. It provisions and controls one systemd unit per application, runs tenant applications with the tenant's operating-system identity, and exposes scoped lifecycle, status, and log operations.
Nginx and per-account PHP-FPM remain responsible for PHP and HTML. SCTR is for Node.js, Python, Go, Rust, workers, WebSockets, schedulers, and similar long-running applications.
The first target is a small, auditable control plane rather than a generic
systemd proxy. The 0.0.1 contract will be accepted only after the smallest
end-to-end hosting workflow is proven.
- Rust/systemd design
- Security model
- Testing and validation
- Deployment and operations
- Command-line contract
- Legacy Python audit
SCTR requires Rust 1.85 or newer and uses the Rust 2024 edition:
cargo build
cargo test
The repository still contains the superseded Python prototype for historical reference. It is not part of the Rust build or runtime.
The first executable slice provides an agent-facing command tree and detailed operational help:
sctr help
sctr help app
sctr help app start
The accepted application contract is:
sctr app list
sctr app status <app>
sctr app start <app>
sctr app stop <app>
sctr app restart <app>
sctr app logs <app>
Lifecycle execution currently fails closed until the registry policy and typed systemd adapter are implemented. The help surface documents those prerequisites rather than reporting false operational success.
