Summary
Snyk Open Source is a commercial appsec tool that scans open-source dependencies for known vulnerabilities and license issues as part of a software supply-chainsoftware supply-chainThe dependencies, tools and processes used to build and deliver software. Compromising one part can affect the products or organizations that rely on it. security workflow. It runs as a hosted service that connects directly to source code management platforms, importing projects and running PR checks without requiring a CLI, though a CLI is also available for teams that want local scans. It supports Python projects using the uv package manager and Go projects with private dependencies served through module proxies like Artifactory and Nexus or accessed via private repositories through Broker, which makes it suited to application developers and platform teams managing dependencies across varied languages and private infrastructure. It sits in the software composition analysissoftware composition analysisSoftware composition analysis, identifying third-party dependencies and checking them for known vulnerabilities and license issues.

Launched in 2015, it continues to receive steady feature releases expanding SCMSCMSource Code Management: version-control systems (Git, SVN, etc.) that track changes to code over time, giving cyber tools reproducible builds, audit trails, and collaborative development workflows. and package-manager coverage.
Snyk Open Source scans and fixes vulnerabilities in open source dependencies used in your applications automatically.
Snyk Open Source publishes no documentation we track, so the description above is written from general knowledge rather than the vendor's own words.
How Snyk Open Source helps
Which of my open-source dependencies have known vulnerabilities?
scans the dependency tree of an imported project and flags packages with known vulnerabilities, tied to the manifest that pulled them in
Which of my dependencies carry license terms that could cause legal risk?
checks resolved package licenses against policy and flags ones that violate it, alongside the vulnerability findings
Will merging this pull request introduce a new vulnerable dependency?
runs a check against the proposed dependency changes in the pull request and reports new issues before the merge happens
Can I track vulnerabilities in Python projects that use uv for dependency management?
imports uv projects and workspaces directly from a connected Git repository and runs the same PR checks and monitoring as other package managers, without needing a local scan
Can I scan Go dependencies that live behind my organization's private infrastructure?
resolves private Go modules through configured module proxies like Artifactory or Nexus, or through private repositories reached via Broker, across all connected SCM integrations
Does a custom branch get the same visibility as my default branch?
keeps repository content, including open source project data, in sync for custom branches as well as the default branch, so scans reflect work happening outside the mainline

Five scores for Snyk Open Source, each built from the releases, notes and API history this site tracks — and, on Researcher and Business, where it stands among every measured tool in its category and how that has moved.
Score cards are part of every paid plan.

Blank means never measured; nothing here is a filled-in zero.
Peer standings are included with Researcher and Business. See how this tool ranks against its competitors, using data we don't publish anywhere else.
See plans →Each score is 0–100 on a published rubric, derived from data this site already shows. A dimension we cannot measure says so — it is never scored 0 and never enters a rank.
How this is scored
- Shipping velocity — releases a month over the last 12 months, on a log scale where 16 a month scores 100. Needs 3 releases in the window.
- Documentation quality — the release-notes rubric published on the analytics page, unchanged.
- Breaking-change discipline — the share of releases carrying a breaking change (none scores 100, half or more scores 0). Only projects that label breaking changes are measured: a clean record cannot be told from an unlabelled one.
- Maintenance risk — quiet time measured against the tool's own release cadence (quiet longer than 90 days and three typical gaps scores 0), plus the number of active maintainers and whether contributors are growing, where known. Higher is lower risk.
- Innovation & surface — new capabilities in the feature ledger this year, API and MCP operations added, and the share of commits that are features: the mean of whichever we hold.
- Community health (open-source tools only) — each is a direction, not a size: contributors this year against last, the bus factor now against a year ago, and issues closed per issue opened, where steady scores 50, doubled 100 and halved 0; plus the median time to a maintainer's first reply (an hour scores about 100, a month or more 0). A commercial card has no repository and carries none of the four.
- Documented delivery (commercial tools) — when a vendor's documented new capabilities have slowed against its own baseline, that counts against the overall standing as heavily as two low dimensions. Steady delivery, or too little history to judge, leaves the standing alone; it is never a sixth score.
- Open-source tools are scored on repository signals; commercial tools on their published changelog. Ranks compare tools within one category and one profile and need at least five measured peers; the overall standing needs three ranked dimensions. Best-in-breed or consolidator is a shape, not a quality, and is never scored.

pricing & packaging history · Snyk vendor page53 readings of Snyk's pricing page since Sep 2021, with 7 relaunches of its plan lineup and 28 changes to what its plans include — each one dated, compared with the reading before it, and explained for someone buying the tool.

Each offering on the pricing page links to its own page of plans, read at its latest capture.
Plan relaunches
Plans, prices and descriptions are quoted from the vendor's own pricing page as we read it on each date. A plan missing from a later reading is shown as no longer listed on the page — a statement about the page, not the product. Readings that failed to show any plans are left out rather than read as a change.

new Python 3.15 support
We're happy to announce that we now support Python 3.15. Following its release on October 9, 2026, this support is now generally available (GA). You can now scan your Python 3.15 projects using both the command line interface (CLI) and your source control manager (SCM) integrations.

How we count
Read from 2 of 6 release notes and docs updates we hold for Snyk Open Source. "First seen" is the earliest note that names something; "last" is the latest. Our history may start partway through Snyk Open Source's life, so an old integration can show a recent first-seen date.
Each change counts once: "added 40 checks" is one line, so the numbers measure how often coverage moves, not how big the catalogue is or how well it detects.
