Managed Debian Repository
Snapshots You Can Trust

Immutable, GPG-signed APT snapshots delivered on schedule — so your team ships with confidence, not firefighting package updates.

  • Original GPG signatures preserved
  • Scheduled production updates
  • Audit-ready immutable snapshots
Package Master — powered by drumlin

Trusted by teams managing critical package supply chains

Product

Everything you need to manage Debian packages at scale

Managed Updates

Subscribe to scheduled, production-ready updates. No dedicated engineering time required.

  • We handle the cadence
  • You focus on shipping

Signature Integrity

Original upstream GPG signatures are preserved on all metadata. Cryptographic proof end-to-end.

  • No re-signing or proxy signatures
  • Simplifies approvals and compliance

Simple UI

Three core concepts — Mirror, Snapshot, and Publish Endpoint — managed through a clean interface.

  • No command-line gymnastics
  • Intuitive workflow

Storage Deduplication

Every package is stored once across all mirrors and snapshots. Cut storage costs without sacrificing coverage.

  • Single copy per package
  • Faster access, lower cost

Cross-Repository Search

Find any package across all your mirrors and snapshots instantly. One search bar, every repository.

  • Unified search
  • Every version, one place

How It Works

Three concepts. Full control.

Package Master organizes everything around three simple primitives.

01

Mirror

A time-specific copy of an upstream repository.

Why it matters: Captures the exact state of every package and metadata at a point in time.

02

Snapshot

An immutable freeze of a mirror.

Why it matters: Once created, a snapshot never changes — stable reference for deployments and audits.

03

Publish Endpoint

A unique URL used to deploy snapshots to your fleet.

Why it matters: Point your servers at it; every machine gets the exact same packages every time.

Security & Compliance

Built for teams that answer to auditors

Package Master preserves cryptographic integrity at every layer, giving your security and compliance teams the evidence they need.

Integrity

Every piece of repository metadata retains its original upstream GPG signature. No re-signing, no proxy signatures — the cryptographic chain of trust is preserved end-to-end.

Immutability

Once a snapshot is created, it cannot be modified. This guarantees that what you tested is exactly what you deploy — and exactly what auditors can verify after the fact.

Auditability

Every mirror, snapshot, and publish action is timestamped and traceable. Build a clear audit trail that maps to your organization's change control process.

Cost & Efficiency

Reclaim engineering time. Reduce storage costs.

Managed updates and package deduplication mean your team spends less time on repository maintenance and less money on redundant storage.

Infrastructure

Powered by Cloudflare

Package Master leverages Cloudflare's global edge network for fast, reliable package delivery at reduced operating cost. Your snapshots are served from the edge — close to your infrastructure, wherever it runs.

Roadmap

Vulnerability Checking Integration

Coming next

Automated USN/CVE parsing to verify whether known vulnerabilities are fixed in a given snapshot. Simplify patching workflows by checking the security posture of any snapshot before deploying.

What Teams Say

Trusted by infrastructure leaders

We cut our repository maintenance overhead by more than half. The managed updates alone justified the switch.

Enterprise Infrastructure Lead

Immutable snapshots with preserved GPG signatures made our last compliance audit significantly smoother.

Head of Security Engineering

Simple enough that our ops team adopted it in a day. Powerful enough that our security team trusts it.

FAQ

Common questions

Package Master stores and serves the original upstream GPG signatures on all repository metadata. We never re-sign or proxy-sign — the cryptographic chain of trust runs directly from the upstream maintainer to your servers.

Package Master is a hosted service. Your repositories are managed in the cloud and delivered through Cloudflare's global edge network. No infrastructure to maintain on your side — just point your APT configuration to your publish endpoint URL.

Repository data is stored in secure cloud infrastructure with Cloudflare's edge for delivery. If your organization has specific data residency requirements, contact us to discuss options for your compliance needs.

Enterprise SSO and SAML integration is on our roadmap. Contact us to discuss your identity provider requirements and timeline.
