Snyk and uv, Better Together

Why uv is winning over Python developers

Built by Astral, uv is a modern, high‑performance Python package manager and resolver, designed to be a drop‑in replacement for teams using pip, pip‑tools, Poetry, and other Python packaging tools.

Since its launch two years ago, uv has seen explosive adoption:

• 80 K stars on GitHub
• Serving 500 million requests per day
• Becoming the tool of choice for popular AI‑native projects like FastMCP, Pydantic, BentoML, Instructor, Outlines, and Anthropic’s Python SDK

At Snyk, we quickly adopted uv internally—for application development and for features like agent‑scan in Evo.

Recognizing the need for supply chain security

When teams evaluate a new tool, two questions always come up:

• Is it secure?
• Will it integrate with our existing toolchain?

Shortly after uv’s release, developers in the Python community began asking whether uv could support exporting dependencies in standard SBOM formats — without that, integrating uv projects into security and compliance pipelines would create friction.

We saw the same demand from Snyk customers eager to adopt uv but needing a seamless way to maintain supply‑chain visibility. We partnered directly with the uv maintainers and contributed support for native CycloneDX export — see the pull request.

Using uv and Snyk together

With CycloneDX support now available in uv, securing a project is straightforward.

Step 1: Export a CycloneDX SBOM from uv

Generate a CycloneDX SBOM in JSON format that includes the project’s dependencies.

Step 2: Test the SBOM with Snyk

Use Snyk to test the SBOM for vulnerabilities and license‑compliance issues, giving developers clear visibility into both security and license risks directly from their uv‑managed dependencies.

Securing uv projects at inception

SBOM export was just the beginning. To make the experience even more seamless for developers using uv, we built native uv support into:

• The Snyk CLI
• IDE integrations
• Agentic workflows

Native support for uv is currently available to Enterprise customers as part of a private preview, with an Early Access launch planned for all customers and free users in April 2026.

Our goal is simple: if you’re building with uv, security should feel built‑in—not bolted on. As uv becomes the modern standard for Python package management, Snyk is committed to ensuring that its speed and efficiency gains are never compromised by security concerns.

By combining uv’s high‑performance dependency resolution with Snyk’s industry‑leading AI security platform, teams can confidently build, install, and secure their AI‑native applications from inception.
