HOME / SPARTYX VS SEMGREP

Spartyx vs Semgrep, the harder comparison.

Semgrep is open source, free for small teams, and better than us at the thing a scanner is mostly judged on. This page says where that leaves Spartyx, and where it does not.

Both products checked August 2026, against semgrep.dev and Semgrep's own Community Edition documentation. Spartyx is compared as the beta that ships today, and Pro is $29 a month.

Came here from Snyk? Five alternatives compared, including this one and three others.

SIDE BY SIDE

Thirteen dimensions. Semgrep wins seven.

If you can write rules, Semgrep is the better tool and the table below will not talk you out of it. The rows Spartyx wins are about price and about who reads the output.

Licence
You can read Semgrep CE, run it offline, and keep running it whether the company continues or not. That is a real property and we do not have it.

Custom rules
If you have a security engineer who wants to encode your own patterns, this is the whole argument and it settles it.

Cross-file taint tracking
Semgrep's free platform tier includes cross-file analysis, so both are free. But the open-source CLI on its own is not the thing doing it.
Yes, in the free betaPlatform only — Community Edition is single-file, single-function
Neither
Free tier scope
Semgrep's free tier is considerably more generous. Spartyx is in beta and capped.

Spartyx
Scanning the running website
Not a gap in Semgrep so much as a different job: it is a static analyser by design. Teams that want both usually pair it with a separate dynamic scanner.

A CLI runs anywhere. A GitHub Action runs on GitHub. On GitHub Actions the two are comparable; off it, Semgrep is the only one of the pair that runs at all.

CHOOSE SPARTYX WHEN
  • You want to see what a scanner finds before installing anything.
  • The output has to be readable by someone who is not an application security engineer.
  • You need a document to hand to a client, an auditor or an investor.
  • You do not have anyone to write and maintain custom rules.
  • You want the deployed site checked too, not only the source it was built from.
CHOOSE SEMGREP WHEN
  • You want a scanner you can read the source of and run offline.
  • You have security engineering time to write rules for your own codebase.
  • Your CI is not GitHub Actions, or you want to run the scan offline.
  • Your stack is in the languages Semgrep covers and Spartyx does not.
  • You want it flagging issues in the editor while you type.
THE ACTUAL DIFFERENCE

Semgrep gives you a finding. We are trying to give you a report.

Both tools will tell you there is dynamic SQL on line 412. The difference is what happens next, and who has to be in the room for it to mean anything.

For someone without the vocabulary

Every finding opens with what it is in plain words, then where exactly — the folder, the file, the line range — and then the lines themselves. The proof, data flow and CWE references sit underneath for whoever wants them.

A document, not a dashboard

SARIF is a format for another tool to read. When a client asks what your security posture is, the answer is a PDF with a verification id they can check — not a seat in a platform they do not use.

Rules you do not have to write

Semgrep's custom rules are its best feature and its cost: someone has to write and maintain them. If that person does not exist on your team, the advantage is theoretical.

Run both on the same repository.

It is the only comparison that settles anything, and ours takes a URL and no account. Read both reports and decide which one you would send to someone.
