CST VerdictBased on our analysis of core features, integrations, here is our conclusion:
AppSec teams running frequent web application assessments will get the most from CORStest because it isolates CORS misconfigurations that slip past broader vulnerability scanners, and the free pricing means you can run it as often as you want without licensing friction. With 419 GitHub stars and active maintenance, it's trusted enough for inclusion in scanning pipelines where CORS-specific coverage matters. Skip this if your org needs a generalist scanner that also catches SQL injection, XSS, and authentication flaws in one tool; CORStest does one thing and won't replace your primary web application scanner.
