Snyk Open Source

Snyk Open Source is a software composition analysis tool for developers working to find and address vulnerabilities and license issues in open source dependencies. It scans dependencies in IDEs and the command line, checks pull requests before merge, adds guardrails to CI/CD pipelines, and monitors projects for newly found vulnerabilities. Its risk scoring considers reachability, exploit maturity, and EPSS/CVSS scores, with business and application context available to refine priorities. Snyk can open pull requests with dependency upgrades and patches, and organizations can customize the titles, descriptions, and commit messages used in those requests. The product also supports continuing checks against regulatory and internal security policies, reporting, and automated license-policy enforcement. Listed integrations include GitHub, Jira, Bitbucket Server, and IntelliJ. Supported languages include C/C++, Java, JavaScript, Python, and others; Rust support is limited. The Free plan is $0.00 per month for 5 projects. Team costs $25.00 per month, billed monthly, and allows up to 10 developers and 100 projects.

Snyk Open Source combines dependency analysis, remediation workflows, and license governance. Its free tier is limited to five projects; Team is $25.00 per month, billed monthly.

Snyk Open Source suits development teams managing open source dependencies and security engineers or GRC teams handling policy reporting. Team is listed for groups of up to 10 developers.

Snyk Open Source is a software composition analysis tool for managing security and license risks in open-source dependencies. It is best suited to development teams that want dependency checks in their coding and delivery workflows, with policy reporting also serving security engineers and GRC teams. Its broad coverage is useful, but the five-project free cap and 100-project Team limit matter as portfolios grow.

Overview

Snyk connects dependency review with remediation and ongoing governance rather than stopping at vulnerability discovery. Scanning in development tools, pull requests and CI/CD can bring issues forward in the workflow, while continuous monitoring tracks projects for newly identified vulnerabilities. Its focus is source-code analysis, supplemented by registry, image and infrastructure analysis; it does not provide runtime protection.

Key features

Developers can scan dependencies in IDEs and the CLI, check pull requests before merge, and add security guardrails to CI/CD pipelines. Automated fixes can open pull requests with required upgrades or patches, and customizable templates let organizations control their titles, descriptions and commit messages. This is a practical advantage for teams that want remediation to fit established review conventions, though generated changes still enter a pull-request workflow rather than eliminating review.

Risk scoring considers reachability, exploit maturity and EPSS/CVSS scores, with business and application context available to refine prioritization. That gives teams more to weigh than a raw vulnerability count. Snyk also monitors projects for newly identified issues and supports real-time and historical reporting against regulatory and internal policies.

License controls provide visibility across projects, customizable policies and automated enforcement. Integrations include GitHub, Jira, Bitbucket Server and IntelliJ. Supported ecosystems include C/C++, Dart and Flutter, Elixir, Go, Java and Kotlin, JavaScript, .NET, PHP, Python, Ruby, Scala, Swift and Objective-C, and TypeScript; Rust support is limited. The product also supports npm, pnpm, Yarn, Maven, Gradle, Pip, Poetry, pipenv and setup.py.

Beyond dependency analysis, Snyk supports SBOM generation, registry and image scanning, and Kubernetes, Terraform and CloudFormation analysis. That wider supply-chain and infrastructure scope is useful for teams consolidating checks, but should not be mistaken for runtime protection, which is not included.

Pricing

The Free plan costs nothing, billed monthly, and includes Snyk Open Source with a limit of 5 projects. It is a sensible starting point for an individual or small evaluation, but the cap makes it unsuitable for a broad portfolio.

Team costs $25 a month, billed monthly, for up to 10 developers and 100 projects. It adds Jira integration and next business day support. The project allowance is a substantial step up from Free, but the developer and project ceilings constrain larger teams.

Enterprise has custom pricing. Credits apply across Snyk capabilities, and Open Source is priced at 1 credit per active contributor per day. That model is aimed at organizations buying across capabilities; teams should weigh active-contributor usage when considering scale.

Platforms

Snyk lists API, Linux, macOS, web and Windows platforms, with cloud deployment. Its development coverage includes IDE and CLI scanning, pull-request checks and CI/CD integration. The company says its controls are externally reviewed annually for ISO 27001 and ISO 27017, and its SOC 2 Type II controls are assessed annually.

Who it's for

Development teams that want vulnerability detection, fixes and monitoring integrated across the software delivery process are the clearest fit. Security engineers and GRC teams can also use the policy evaluation and reporting for ongoing oversight. Teams needing runtime protection, or larger groups that would exceed Team's 10-developer or 100-project limits, should look beyond these plans.

Pros and cons

• Pro: Scanning spans IDEs, pull requests, CI/CD and continuous monitoring, helping teams address dependency risk at multiple stages.
• Pro: Reachability, exploit maturity and EPSS/CVSS factors add context to prioritization, while automated pull requests support remediation.
• Pro: License governance and policy reporting extend the product's use to compliance workflows.
• Con: Free is capped at 5 projects, and Team at 100 projects and 10 developers, limiting headroom for growing portfolios.
• Con: Rust support is limited, and runtime protection is not part of the offering.
• Con: Enterprise uses a credit model tied to active contributors per day, which may be less straightforward to plan than a fixed monthly tier.

Alternatives

FOSSA is worth considering when its free plan's 5 projects, 10 contributing developers, one release group and five dependency levels for scans match your needs; it also offers a free trial. Endor Labs suits individual developers looking for free local scans through its AURI MCP server without an account, provided they do not need a UI, policies or scan history.

Semgrep Supply Chain is an option for teams that fit its Free Edition limit of 10 repositories and 10 contributors with GitHub or GitLab authentication. Socket may suit teams whose needs align with its Team plan: $25 a month per developer, a five-developer minimum, and 5,000 scans per month.

Xygeni has a free plan for up to five contributors and 10 repositories, with 200 scans per month and SAST, SCA, secrets security and an IDE plugin. Trivy is a free, Apache-2.0-licensed open-source scanner. OSV-Scanner is a free open-source scanner offered as a CLI and Go library, with SLSA3-compliant binaries. Black Duck SCA is another paid option.

Verdict

Snyk Open Source is a strong choice for development teams that want dependency risk detection, guided fixes and policy governance in one workflow. Its strongest case is the combination of development-stage scanning, contextual prioritization and continuous monitoring. Look elsewhere if you need runtime protection, broader Rust coverage, or project and developer limits beyond the Team plan.
