Repowise / Snyk Code
Repowise vs Snyk Code: the decision is not a checklist.
Decide whether the main need is finding security vulnerabilities, or understanding the repository and its code health.
Snyk Code is the appropriate choice when source-code security scanning and remediation are the buying requirement. Repowise covers code health, git history and architecture, and it does not replace a dedicated SAST program.

01 / Category framing
What each product is built to do.
- Repowise
- A persistent codebase-intelligence layer that combines structure, git history, decisions, code health, generated documentation, and MCP retrieval for both people and coding agents.
- Snyk Code
- Developer-focused static application security testing for finding and remediating vulnerabilities in source code.
How it works
Is Snyk Code a code quality tool?
Snyk Code is no longer a code quality tool. It is a static application security testing (SAST) tool that looks for vulnerabilities such as injection flaws in your own source code. For a while it also reported code quality issues, but Snyk's documentation announced that Snyk Code Quality issues would no longer be provided from June 24, 2025, and its current pages describe Snyk Code results as security vulnerabilities only.
So if you searched for Snyk code quality because you want maintainability, complexity, dead code or hotspot signals, Snyk Code is not the tool for that job today. Snyk's own glossary draws the same line: static code analysis covers quality and structure broadly, while SAST targets security vulnerabilities.
Reachability in Snyk is a different feature from Snyk Code. It belongs to Snyk Open Source (dependency scanning) and checks whether your application calls the code element behind a vulnerable dependency. Snyk documents it as generally available for Java, JavaScript/TypeScript and Python, and in early access for C#.
02 / Overlap and difference
Where the workflows meet, and where they diverge.
Genuine overlap
- Both inspect source code and surface findings at actionable locations.
- Both can inform review before risky changes merge.
- Starting point
- Snyk Code centers security findings and remediation. Repowise centers code health, architecture, git risk, decisions, and repository context.
- Operating model
- Snyk Code is part of the Snyk developer-security platform. Repowise offers hosted and open-source self-hosted operation.
- Evidence boundary
- No controlled head-to-head benchmark is claimed on this page. Product descriptions come from the linked primary documentation.

Scroll sideways to read both products and the caveat column.
| Buying question | Repowise | Snyk Code | Boundary |
|---|---|---|---|
| What does it check? | Code health (defect, maintainability and performance markers), dead code, hotspots and ownership from git, dependency CVEs and secrets across git history. | Security vulnerabilities in first-party source code (SAST), with AI-assisted fixes. Code quality issues were discontinued on June 24, 2025. | The two products do different jobs: code health on one side, application security on the other. |
| Languages | 16 languages parsed to a full syntax tree, 11 at the Full tier. | Apex, C/C++, COBOL, Dart/Flutter, Go, Groovy, Java/Kotlin, JavaScript, .NET (C#, VB.NET), PHP, Python, Ruby, Rust, Scala, Swift/Objective-C and TypeScript, with interfile analysis for all but COBOL. | Snyk's language list for SAST is broad. |
| Reachability | Dependency CVEs are filtered by whether your code imports the affected package, through the dependency graph. Repowise does not do function-level reachability today. | Snyk Open Source reachability checks whether your code calls the vulnerable code element. GA for Java, JavaScript/TypeScript and Python; early access for C#. | Snyk's reachability is finer grained today. |
| Uses git history? | Yes. It mines hotspots, ownership, bus factor, co-change and bug-fix history from git, using the full history on paid plans. | Not for prioritization. Snyk ranks issues with a priority score built from severity, exploit maturity, reachability and fix availability. | Snyk prioritizes by exploitability; Repowise by change history and structure. |
| Coding agents | MCP server with 10 tools (answers, search, context, symbols, rationale, risk, health), usable from Claude Code, Cursor, Claude.ai and other MCP clients. | Snyk MCP server, included in the Snyk CLI, lets agents run scans and work with findings. | Both can be called from an agent. |
| Where it runs | Open source under AGPL-3.0 and self-hostable, or hosted at repowise.dev. | Snyk's managed platform, with IDE, CLI and source-control integrations. | Confirm data-handling terms with each vendor. |
| Price | Free for public repositories (git analysis on the last 500 commits). Pro $15/month, Teams $20/seat/month. Self-hosting is free. | Free plan: 100 Snyk Code tests per month. Team plan from $25/month with 1,000 tests per month. Enterprise uses credits (1 credit = $1). | Prices from snyk.io/plans on the verification date. |

One result you can check
Unused code is one of the quality signals Snyk Code no longer reports. Repowise's index of langchain-ai/langchain (2,859 files) finds 19 dead exports: exported symbols that nothing in the repository imports. That is a small number for a codebase that size, and each one is listed with its file so you can confirm it. We did not run Snyk Code on langchain for this page.

Choose Repowise when...
- You need maintainability, defect-risk, performance, history, and architecture evidence together.
- You want one repository index for engineers and coding agents.
Honest trade-off
Choose Snyk Code when...
- You need a dedicated SAST product and vulnerability remediation workflow.
- Security program integrations and security reporting drive the purchase.
06 / Verification notes
What this brief does not claim.
- No controlled head-to-head performance or quality result is claimed between these products.
- Competitor capabilities, packaging, deployment terms, and prices can change after the verification date.
- A product-category comparison is not a security, compliance, procurement, or legal assessment.
- Repowise evidence links show current product output; they are demonstrations, not proof that every repository will produce the same findings.

Common questions
Everything people ask before they try it.
Is Snyk Code a code quality tool?
No, Snyk Code is a SAST tool for security vulnerabilities. Snyk announced that Snyk Code Quality issues would no longer be provided from June 24, 2025, so maintainability and code smell checks need a different tool.
What is Snyk reachability analysis?
It is a Snyk Open Source feature that checks whether your application calls the code element related to a vulnerability in a dependency. It uses static program analysis and AI techniques and does not need the application to be built. It is GA for Java, JavaScript/TypeScript and Python, and early access for C#.
Does Repowise do reachability?
Repowise does part of it. It filters dependency CVEs by whether your code imports the affected package, using its dependency graph, and scores them with KEV (the CISA list of known exploited vulnerabilities) and EPSS (a score for how likely a vulnerability is to be exploited). Repowise does not do function-level reachability today, the kind Snyk Open Source offers.
What is a good Snyk Code alternative for code quality?
For rule-based quality checks, look at SonarQube, Codacy or Qlty. For prioritizing which files to fix using git history (hotspots, ownership, co-change) plus code health, Repowise is built for that. Keep Snyk Code if application security scanning is the requirement.
Can Repowise replace Snyk?
Repowise cannot replace Snyk as a SAST program. It covers dependency CVEs and secrets, but it does not scan your own code for injection-style vulnerabilities. Teams that need SAST should keep Snyk Code or another dedicated scanner.
