Best SBOM Tools 2026: How to Choose the Right SBOM Generation Tool
Compare the best SBOM tools for 2026. Expert analysis of Waybill, cdxgen, Syft, npm-sbom & more. Choose the right SBOM generator for your needs.
There are so many tools to build SBOMs for your application. How do you know which one to pick? This updated SBOM tool comparison will help you select the right solution for your software supply chain security needs.
Single-Language SBOM Tools
When your application and its dependencies are all written in the same programming language, SBOM generation gets much easier. When the build tool itself has SBOM generation built-in, they’re typically able to quickly produce more reliable SBOMs, including transitive dependencies, because the tool generating the SBOM is the one doing the dependency resolution.
npm-sbom: Best Choice for Node.js
Some ecosystems, like Node.js have first-party SBOM generators. For Node applications, the npm-sbom command is a great choice. npm-sbom easily integrates into existing Node workflows and can produce SBOMs in either of the two most popular specifications: CycloneDX and SPDX.
Key Features:
- Native Node.js integration
- Supports both CycloneDX and SPDX formats
- Comprehensive transitive dependency analysis
- Zero configuration required
Best for: Pure Node.js applications where accuracy is critical
CycloneDX Language-Specific Tools
CycloneDX produces language-specific tools for a variety of ecosystems, including Java (including both the maven and gradle build systems), Node.js (including NPM and Yarn), Python, and Golang.
These tools analyze both direct and transitive dependencies, providing a thorough inventory of all components within a project. This depth of analysis enhances supply chain transparency and security. These tools are well-maintained, in contrast to some other language-specific tools we examined. An important note if you use multiple language-specific tools across your portfolio: the per-ecosystem CycloneDX tools are independently governed projects that make independent decisions about defaults, releases, and command syntax. The usage and SBOM output will vary from tool to tool.
Best for: Single-language projects requiring maximum accuracy
Multi-Language SBOM Tools
While single-language tools often have the best accuracy and depth, not all software projects are single-language efforts. An application might have a front end written in Node, a backend written in Rust, and a command line client written in Go. You need a tool with multi-language support in order to handle those applications.
Waybill: Top Multi-Language Option
We’ll admit: we’re biased in favor of Waybill. We wrote it to address gaps in existing SBOM tools, so it’s no surprise that it’s the best fit. Waybill captures transitive dependencies, including relationships, and can optionally augment with data from sources like Deps.dev. The CNCF generates per-release SBOMs with Waybill across 1,500+ projects and subprojects, more than 16,000 SBOMs to date. CNCF is a software steward under the EU Cyber Resilience Act, which makes the SBOMs it produces a compliance artifact. For the compliance-minded, it also explicitly covers the CISA 2026 Minimum Elements for a Software Bill of Materials.
Key features:
- Support for 15 language and operating system ecosystems
- Support for tracing binaries
- Comprehensive transitive dependency resolution
Pros:
- Best graph fidelity available
- Robust artifact identity
- Supports both CycloneDX and SPDX formats
- Support for in-toto attestation
- Easy deployment with a single, self-contained binary
Cons:
- Small user base
- Still in an alpha state
Best for: cryptographically verifiable, precisely-identified SBOMs
cdxgen: Most Flexible Multi-Language Option
cdxgen from CycloneDX is the official SBOM generation tool of the Open Worldwide Application Security Project (OWASP). It supports a wide array of programming languages, including transitive dependencies for certain ecosystems, and can generate SBOMs in the CycloneDX format. It also offers an API for SBOM generation, so it could be easier to integrate into various workflows.
Key Features:
- 20+ supported programming language

- Handles complex dependency scenarios
Cons:
- Can be resource-intensive for very large projects
- Occasional false positives in complex scenarios
- Runs build tooling, which can be an attack vector
Best for: coverage across a wide range of languages, artifact types, and document formats
Syft: Container-Focused Alternative
syft from Anchore is another popular multi-language SBOM generator. Syft can analyze multiple ecosystems, including Python, Go, Java, JavaScript, PHP, and Rust, making it versatile for diverse projects. Syft integrates well into CI/CD pipelines, facilitating automated SBOM generation during the build process. It is fast, but that speed sometimes comes at the cost of missing dependencies other tools find.

Step 3: Test Multiple Tools
In general, it's best to pick a language-specific tool if you have a single-language application. These tend to produce the highest-quality SBOMs, especially if it's an official ecosystem tool. For multi-language applications, we've found Waybill to be the most reliable. However, you should try several tools to see which integrate best into your workflows and give the best results for your portfolio.
Testing Checklist:
- ✅ Generate test SBOMs with 2-3 different tools
- ✅ Compare dependency detection accuracy
- ✅ Test CI/CD pipeline integration
- ✅ Measure build performance impact
- ✅ Validate output format compatibility

Frequently Asked Questions
What Are SBOM Generation Tools?
Software Bills of Materials (SBOMs) are the foundational piece of understanding your software supply chain. An SBOM generation tool inspects a codebase, a build, or a container image and produces a machine-readable inventory of every component inside it, in a standard format such as CycloneDX or SPDX. Some are built into a language ecosystem and cover one language deeply. Others scan across many ecosystems at once. What separates them in practice is how much of the transitive dependency tree they resolve, whether they record the relationships between components rather than producing a flat list, and whether they tell you when they could not resolve something.
Should I use multiple SBOM generation tools?
For critical applications, running more than one generator and comparing the output is worth the overhead, because different tools resolve different parts of the tree and the disagreement between them is itself informative. Two things make it work in practice. Standardise the output format so downstream tooling does not have to handle both, and decide in advance what happens when the two disagree — a difference nobody adjudicates leaves you with two inventories you trust equally and neither of which you can defend. For most teams the workable pattern is one primary generator in every build, plus a second run periodically against the components that matter most.
How often should I generate new SBOMs?
You should generate new SBOMs with every build to maintain currency and accuracy. An SBOM describes one specific artifact and dependency resolution can change between builds even when no source code changed. We recommend storing them per release rather than overwriting a single current file. This ensures your SBOM reflects the latest dependency changes and security updates.
What's the difference between SPDX and CycloneDX formats?
The difference between SPDX and CycloneDX formats lies in their primary focus and use cases. SPDX (Software Package Data Exchange) emphasizes licensing and compliance information, making it ideal for legal and procurement teams. CycloneDX focuses on security applications, providing richer vulnerability and dependency relationship data that security teams prefer. Many organizations choose based on their primary requirements, though some tools support both formats.
Can imperfect SBOMs still provide value?
Absolutely. Imperfect SBOMs still provide value because having some visibility into your software composition is infinitely better than having none. Even if your SBOM misses some dependencies or lacks complete metadata, it still gives you a foundation for vulnerability management, license compliance, and supply chain risk assessment. You can improve SBOM quality over time while gaining immediate benefits from what you have.
However, an incomplete SBOM without saying so can be dangerous because it gives you a false sense of confidence. It’s important to know whether a vulnerability doesn’t appear in your list because it’s not actually there or because the SBOM missed the affected dependency.
How do SBOM tools integrate with vulnerability scanners?
SBOM tools integrate with vulnerability scanners by providing standardized data formats that vulnerability management platforms can consume. Most modern SBOM generators export in SPDX or CycloneDX formats, which vulnerability scanners can directly import to correlate your dependencies with known CVEs. This integration enables automated vulnerability assessment workflows and continuous monitoring of your software supply chain risks.
What's the relationship between SBOM generation and DevSecOps?
The relationship between SBOM generation and DevSecOps is foundational to modern secure development practices. SBOM generation enables shift-left security by providing early visibility into dependencies during development, allowing teams to identify and address risks before they reach production. This supports DevSecOps principles of continuous security monitoring, automated compliance checking, and integrating security seamlessly into CI/CD pipelines.
What’s the difference between an SBOM generator and an SCA tool?
An SBOM generator produces an inventory of what is in your software. A software composition analysis tool takes an inventory and matches it against vulnerability advisories to tell you what is known to be wrong with it. The two are frequently bundled, which is why the distinction gets lost, and the practical consequence is that an SCA tool's findings are only as complete as the inventory underneath them. If the inventory missed a transitive dependency, no amount of advisory matching will surface a vulnerability in it. Choosing a generator is a decision about the input to everything downstream, not a separate procurement question.
Is Waybill free?
Yes, Waybill is open source and free to run and under active development. It ships as a single self-contained binary, is written in Rust, and covers 15 language and operating system ecosystems. CNCF generates per-release SBOMs with Waybill across 1,500+ projects and subprojects, more than 16,000 SBOMs to date. The repository is at github.com/kusari-oss/waybill, and filing an issue is the fastest way to tell us where it breaks.
Do I need an SBOM for the EU Cyber Resilience Act or the CISA minimum elements?
Yes, for the Cyber Resilience Act. The CRA will require manufacturers, starting in December, 2027, to identify and document the components in a product with digital elements, including by drawing up a software bill of materials in a commonly used machine-readable format covering at least the product's top-level dependencies. Starting September, 2026, manufacturers must begin reporting actively exploited vulnerabilities and severe incidents.
CISA's minimum elements work differently. They define what an SBOM should contain rather than compelling anyone to produce one. In July 2026 CISA and seventeen partner agencies replaced the 2021 baseline, raising required data fields from 7 to 18 and adding a required practice to explicitly identify unknown information, which means a tool that cannot distinguish a dependency it resolved from one it gave up on cannot satisfy that practice.
