Best OWASP ZAP Alternatives

Looking for a OWASP ZAP alternative? OWASP ZAP is the free, battle-tested way to actively attack your own web app for XSS and injection flaws before someone else does. That's a good fit for plenty of teams, but not everyone — here are 6 real security tools worth comparing it against, each with an honest take on what it does differently. Snyk is the one people mention most: catches vulnerable dependencies, container images, and IaC misconfigs right in your IDE and CI, before they hit production. Semgrep is another solid option — open-source static analysis with rules that read like code, so you catch real security bugs at PR time instead of in prod. None of these are ranked by who pays the most to be listed first; they're ordered the same way the rest of this directory is, sponsors aside.
