What is Chainguard?

Thu, 23 Jul 2026 00:00:00 +0000

Nearly every modern application is built on open source software. That software is powerful, but it arrives with problems: vulnerabilities (including publicly disclosed CVEs), unpatched dependencies, unclear provenance, and the constant work of keeping it all up to date. Tracking and fixing these issues across a large codebase consumes engineering time that could go toward building products.

Chainguard’s mission is to be the secure source for open source. Rather than leaving you to patch and harden open source software yourself, Chainguard rebuilds it from source in a hardened build environment, keeps it continuously updated, and distributes it with the metadata you need to verify what you’re running. The result is software that carries low-to-no known CVEs and requires far less remediation work from your team.

Getting Started with Chainguard Guardener

Wed, 08 Jul 2026 00:00:00 +0000

This guide walks you through everything you need to start using Chainguard Guardener on your GitHub repositories:

Install the Guardener GitHub App on your GitHub organization.
Link your Chainguard organization to your GitHub organization.
Verify the link and enable your first feature.

Once the app is installed, the Guardener can respond on your public repositories. Linking connects that activity to your Chainguard organization and unlocks the features that require one, such as private repository coverage — there is no separate entitlement step.

Quickstart for Chainguard Containers

Wed, 05 Aug 2026 00:00:00 +0000

This quickstart covers one full cycle of working with a Chainguard Container: pull an image from Chainguard’s registry, run your own code on it, and verify where it came from. The example uses the Node container, but the same workflow applies to every image in the Chainguard Containers Directory.

These steps link to reference documentation instead of explaining each concept in place. Follow the links whenever you want additional details and context.

Chainguard’s chainctl provides command-line access to manage container images, identity resources, and security configurations across your organization. This guide covers essential commands to begin using chainctl effectively in your security and DevOps workflows. For comprehensive command documentation, refer to the chainctl Reference.

Authenticate and Check Auth Status

To use chainctl, the first thing you must do is authenticate with the Chainguard platform. Do so with:
