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.
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.
| Dimension | Spartyx | Semgrep | Better |
|---|---|---|---|
| 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. | Proprietary, hosted | Community Edition is open source | Semgrep |
| Getting a first result | Paste a repo URL in a browser | Install the CLI, or sign up for the platform | Spartyx |
| Custom rules If you have a security engineer who wants to encode your own patterns, this is the whole argument and it settles it. | None — the rules are ours | Its defining feature, plus a large public registry | Semgrep |
| Languages | 14 | 35+ for Code, 16 generally available | Semgrep |
| 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 beta | Platform 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. | 5 scans a month, public repos | 10 contributors, 10 repositories, private included | Semgrep |
| Paid plan shape Flat and undivided against per-contributor and per-product. Worth knowing before you budget. | $29 a month, flat, everything included | $30 per contributor per month, and you pick one of Code, Supply Chain or Secrets | 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. | Included — headers, TLS, cookies, exposed files, forms, subdomains | None — Semgrep reads source code and does not run it | Spartyx |
| Report you can send to someone SARIF is for another tool to read. This is for a person who does not have your terminal open. | PDF with file, line range and a public verification id | CLI output, SARIF, platform dashboard | Spartyx |
| Written for a non-specialist | Every finding opens in plain words before the technical blocks | Written for engineers who already know the vocabulary | Spartyx |
| IDE integration | None | VS Code and IntelliJ | Semgrep |
| CI integration 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. | GitHub Actions, with SARIF into Code Scanning | Any CI — it is a CLI, and that is the normal way to run it | Semgrep |
| Maturity | Beta | Established, large community, widely deployed | Semgrep |
- 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.
- 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.
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.
