Audience

The documentation describes Plain mode for indexing a package directory and Managed mode for maintaining a curated long-lived repository.Read 11 Oct 2026 · sow.pgsty.com

Platforms

The download page lists Linux and macOS builds for amd64 and arm64, and says Windows is not a release target.Read 11 Oct 2026 · sow.pgsty.com

Integrations

SOW builds repository metadata in-process and documents compatibility with RPM/YUM and DEB/APT clients plus filesystem and R2 publication providers.Read 5 Oct 2026 · sow.pgsty.com

Security

R2 credentials must be provided through an environment variable or file reference; inline secrets are forbidden.Read 5 Oct 2026 · sow.pgsty.com

License

The product pages identify SOW as Apache-2.0 licensed.Read 11 Oct 2026 · sow.pgsty.com

Audit and recovery

Managed mode records operations and supports recovery from interrupted writes.Read 5 Oct 2026 · sow.pgsty.com

Format limits

SOW omits SQLite rpm-md, zchunk, modulemd, source-package indexes, and MD5/SHA1 DEB manifests.Read 5 Oct 2026 · sow.pgsty.com

Incremental publishing

The changes command reports publication deltas, and publishing uploads changed objects rather than every repository object.Read 11 Oct 2026 · sow.pgsty.com

Key handling

The signing documentation says configuration, SQLite, logs, JSON output, and error text do not persist secret key or passphrase material.Read 11 Oct 2026 · sow.pgsty.com

Managed filesystem requirement

Managed workspaces require a local POSIX filesystem with advisory locks, fsync, and atomic rename semantics.Read 11 Oct 2026 · sow.pgsty.com

Managed mode

Managed workspaces track package membership, policy, signing, immutable generations, audit history, and publication targets.Read 11 Oct 2026 · sow.pgsty.com

Notable compatibility limit

Plain mode does not generate legacy SQLite metadata or module streams.Read 11 Oct 2026 · sow.pgsty.com

Package storage

Managed mode stores package payloads once in a shared pool and renders metadata views for distributions and architectures.Read 5 Oct 2026 · sow.pgsty.com

Plain mode

Plain mode indexes top-level RPM and DEB files in a directory and writes repository metadata beside them.Read 11 Oct 2026 · sow.pgsty.com

Publication

SOW supports configured filesystem and Cloudflare R2 publication targets, with incremental changes and public visibility checks.Read 5 Oct 2026 · sow.pgsty.com

Publication targets

The documented publication providers are filesystem and Cloudflare R2 via S3-compatible storage.Read 11 Oct 2026 · sow.pgsty.com

Release platforms

Release binaries target Linux and macOS on amd64 and arm64; Windows is not supported.Read 5 Oct 2026 · sow.pgsty.com

Repository views

Managed mode stores each live package once and can expose metadata-only distribution views from a shared pool.Read 11 Oct 2026 · sow.pgsty.com

Serving requirement

SOW emits static repository files and is not an HTTP daemon; users serve the generated public tree with their own HTTP server.Read 11 Oct 2026 · sow.pgsty.com

Signing

Managed mode can sign RPM and DEB repository metadata; RPM package signing is configured separately, and SOW does not re-sign DEB package bodies.Read 11 Oct 2026 · sow.pgsty.com

Workspace filesystem limit

Managed workspaces require a local POSIX filesystem; NFS and other network filesystems are unsupported workspace locations.Read 5 Oct 2026 · sow.pgsty.com
