Snyk Code scans first-party code for security vulnerabilities. Aevral reads whether a change widens who has access to what. Different jobs, same repo, run both.
| Row | Snyk Code | Aevral |
|---|---|---|
| Question it answers | Does this code contain security vulnerabilities? | Who has access to what, and does this change widen it? |
| Stated job | SAST on first-party code with suggested fixes | Access-control and business-logic reading of the repo, and a wider security reading of the PR diff |
| Where it runs | In the Snyk platform, per Snyk's docs | Console scan on the default branch; PR review, live on install |
| Unit of work | The vulnerability match with a suggested fix | The finding as a lead with evidence, across files |
| Complementary? | Yes | Yes |
Snyk Code is built to find security vulnerabilities in first-party code and to suggest the fix. That is the scanning job it states, and it does it inside the Snyk platform, alongside the dependency and container scanning you may already run there. Aevral does a different job: it reads the repository snapshot for access control and business logic, the way a researcher would, file by file with cross-file context, and its PR review rides the same App, live on install, reading a wider class list on the diff.
This page draws the boundary between vulnerability scanning and access-control reading, and shows one worked example of the second. It makes no claim about results on your code; those depend on your code and your configuration.
Snyk Code
Snyk Code is a SAST tool. It scans first-party code for security vulnerabilities and suggests fixes, alongside Snyk's dependency and container scanning.
Aevral
Security review, handled. PR review, live on install, looks for access control, business logic, SQL and command injection, XSS, SSRF, path traversal, unsafe deserialization, token and session flaws, and LLM-integration risks on the diff. Paid PR plans are live in the console. The whole-repo scan is live and self-serve, and reads authorization, IDOR, and business-logic access control only. A finding is a lead with evidence, and a human decides. No patches are auto-applied.
This change removes an ownership assertion from a project-update route, probably because a middleware already logs the user in. The code is clean and readable, the route works for every caller.
export async function PATCH(req: Request, { id }) { const project = await loadProject(id) await assertCanEdit(user, project) return updateProject(project, await req.json())}Signed-in is not the same as allowed. With the edit assertion gone, any authenticated user can update any project by id, which is a direct authorization failure. Aevral is built to read a diff for the missing gate, not the code smell: the change looks like tidying, and the access it grants is the finding.
Keep Snyk Code for vulnerability scanning and suggested fixes; run Aevral for the access-control reading of the repository, and a wider security reading of your pull requests through its PR review, live on install.
No. Snyk Code does its stated job and keeps doing it. Aevral runs alongside it with its own reading: its PR review, live on install, looks for access control, business logic, injection, XSS, SSRF, path traversal, and LLM-integration security on the pull requests it reviews, and its whole-repo scan reads access control and business logic across the repository at rest.
No. This page states each product's job and shows one worked example of Aevral's own reading. Results on your code depend on your code; evaluations belong to you.
Aevral is self-serve: install the GitHub App and log in to the console. The waitlist form is a launch-updates channel; joining does not reserve a price, access, or a contract.
