NightVision vs. Snyk
Snyk acquired Probely and relaunched it as Snyk API & Web, the DAST module of a SAST-led platform. NightVision is purpose-built, whole-app DAST: one workflow crawls and tests your web UI and APIs fully authenticated, can map supported REST routes from source, and can provide Code Traceback on supported source-discovered API scans.
A DAST module inside a platform vs a purpose-built whole-app DAST.
Snyk does do DAST now. The question has changed: is dynamic testing the platform's center of gravity, or one module among many?
Where Snyk excels
Snyk's platform breadth is real: category-leading SCA for open-source dependencies, Snyk Code for SAST in the IDE and PR, plus container and IaC scanning, all under one policy and reporting engine. Snyk API & Web (formerly Probely) adds a credible dev-first DAST leg with a headless-Chrome spider and authenticated scans including SSO/OIDC. If you are consolidating on one vendor across static and dynamic, that is a coherent story.
Where NightVision differs
NightVision is built around dynamic testing, not attached to it. Its API surface is source-derived: API eNVy generates the OpenAPI spec from your code in under 20 seconds, where Snyk API & Web scans the schema you supply, with broader discovery via a traffic-based Akamai partnership. And the code linkage is native: API findings on source-discovered targets carry a deterministic Code Traceback to the file and line in one product, where Snyk's own changelog describes AI-based correlation between an API & Web finding and a Snyk Code issue, requiring both products.
Snyk API & Web (formerly Probely): what to know
Probely was acquired by Snyk in 2024 and relaunched in 2025 as Snyk API & Web, the dynamic-testing leg of the Snyk platform. The scanner is now packaged inside Snyk's platform tiers and still runs on its own portal. If the transition has you re-evaluating, NightVision is purpose-built for the job Probely was built for, whole-app dynamic testing, and adds the pieces Probely never had: source-derived API discovery for the REST endpoints no schema mentions, Code Traceback on supported source-discovered API scans, authenticated scanning with a login-check gate that fails CI instead of silently scanning logged out, and agent-assisted changes and rescans under repository controls. Migration is self-serve: connect a repo and a target, 6 to 12 clicks, no sales call.

Where a purpose-built DAST separates from a platform module
These aren't feature checkboxes. They're the design decisions that change what gets tested and how fixes get shipped.
One product, native linkage
On supported source-discovered API scans, NightVision can provide Code Traceback to the endpoint file and line in the same workflow. Snyk's DAST-to-code linkage is AI-inferred correlation between two products, per their own changelog.
Specs from source, not from you
API eNVy generates an OpenAPI spec from source for supported REST frameworks and can surface routes missing from documentation or observed traffic. Snyk API & Web scans the schema you supply.
The whole app, one workflow
A crawler built for modern single-page apps: LLM-based form handling, WebDriver BiDi-based intelligent waiting, and duplicate page detection, testing the web UI and the APIs behind it together.
Auth that fails loudly
Playwright-recorded logins with auto-vaulted credentials and TOTP/MFA support, plus a login-check gate that fails your pipeline instead of silently scanning logged out.
Human-gated fixes
Coding agents can use finding evidence to propose a change and rescan it under normal repository review controls.
Dynamic-first, not platform-attach
Every roadmap decision serves runtime testing: crawler depth, auth reliability, evidence quality. Dynamic testing is the product, not a module.
The honest answer: it depends on your program.
✅ Choose NightVision when…
- Dynamic testing is the job, and you want the tool built around it
- Your API surface includes undocumented or shadow REST endpoints no schema mentions
- You want native, deterministic file and line linkage on source-discovered API findings, in one product
- You need the web UI and the APIs behind it crawled and tested fully authenticated, with MFA/TOTP
- You want agents to use finding evidence to propose changes and rescan under repository controls
- You need to scan private-network apps without infrastructure changes
Consider Snyk when…
- You're consolidating static and dynamic testing on one vendor, under one policy and reporting engine
- SCA and SAST breadth (dependencies, code, containers, IaC) is the priority, with DAST as one leg
- You're already standardized on the Snyk platform and its developer integrations
- You were a Probely customer and the Snyk ecosystem fits how your team works
The agent-ready dimension
Coding agents are becoming part of every AppSec workflow, so every scanner evaluation picks up a new question: can your agent launch a scan, read the evidence, propose a fix, and verify it? NightVision ships an open-source MCP server and Agent Skills for that whole loop: findings arrive with runtime evidence (file and line on supported source-discovered API scans), the agent makes the change over MCP and rescans, and your review process governs the merge.
Whichever tool you select, ask it the same question; the loop is only as good as the scanner underneath it.
"We won an award at our company's internal hackathon for demonstrating developer teams executing a DAST scan on a web app… during build time, with tickets opened automatically with Engineering."Steve McKinnon · Senior Application Security Engineer, BeyondTrust
Common questions about NightVision vs Snyk
Does Snyk do DAST?
Yes. Snyk acquired the dev-first DAST vendor Probely in 2024 and relaunched it in 2025 as Snyk API & Web, the DAST leg of the Snyk platform alongside SAST (Snyk Code), SCA, container, and IaC scanning. So the real comparison is not DAST vs no-DAST: it's a purpose-built, source-linked whole-app DAST (NightVision) vs a DAST module inside a SAST-led platform.
What happened to Probely?
Probely was acquired by Snyk and relaunched as Snyk API & Web. The scanner lives on as the dynamic-testing leg of the Snyk platform, gated to specific platform tiers and still operating on its own portal. Teams re-evaluating after the transition often shortlist NightVision because it's purpose-built for the same job Probely did, whole-app dynamic testing, and adds source-derived API discovery, Code Traceback on supported source-discovered API scans, and agent-assisted changes and rescans under repository controls.
How does finding-to-code linkage differ between NightVision and Snyk?
On supported source-discovered API scans, NightVision can provide Code Traceback to the endpoint file and line in the same workflow. Snyk's own changelog describes AI-based SAST/DAST correlation: an API & Web finding is correlated to a Snyk Code issue and its line of code, which requires running both products and relies on AI inference to make the match.
Where does each tool's API spec come from?
Snyk API & Web scans the API definition you supply: an OpenAPI or Postman schema via URL or upload, or GraphQL introspection, with broader API discovery delivered through a traffic-based Akamai partnership. NightVision generates the OpenAPI spec from your source code in under 20 seconds with deterministic static analysis, so REST endpoints that were never documented or never called still get discovered and tested.
Do NightVision and Snyk complement each other?
They can. Snyk's platform breadth in SCA, SAST, container, and IaC scanning is real, and many teams keep it for the static side while running NightVision as the purpose-built dynamic layer: fully authenticated whole-app crawling, source-derived API discovery, and Code Traceback on supported source-discovered API scans with evidence coding agents can use to propose changes and rescan.
What does NightVision cost?
NightVision starts at $15,000/year for the Single Application plan, with a free 3-day trial covering up to 4 DAST scans and no credit card required. Enterprise plans are available for teams.
