Content Moderation API
The clearest difference between Checkmarx and StackHawk is pricing — Checkmarx is unknown (no free tier), while StackHawk is subscription (no free tier). Beyond that, lock-in — Checkmarx has high lock-in (Medium-High — enterprise SAST, deep integration), whereas StackHawk has low lock-in (Based on OSS ZAP scanner). The stated fit for both tools is similar on paper: Checkmarx is pitched as enterprise SAST, SCA, IaC, and API security scanning platform covering 30+ languages with IDE and CI integration, while StackHawk is pitched as Developer-centric DAST tool running application security tests in CI/CD using OpenAPI and GraphQL specs. On the strengths side, Checkmarx is cited for UGC platforms (social, marketplace), while StackHawk is cited for Chat/messaging apps. The honest trade-off: both Checkmarx and StackHawk are the wrong call for internal projects. Choosing between them should come down to the constraint that actually binds your workflow, not surface-level overlap. On developer experience the data shows Checkmarx at 3/5 and StackHawk at 5/5, with transparency at 1/5 and 4/5 respectively.

Checkmarx is unknown, while StackHawk is subscription, so the cheaper option depends on your usage shape. Listed pricing pages usually change, so check both directly before committing. For small teams, the free-tier limits often matter more than headline prices.
Migrating from Checkmarx to StackHawk is feasible when their scopes overlap, but the work is in re-mapping configuration, data models, and integrations. Moving off Checkmarx is harder because of high lock-in (Medium-High — enterprise SAST, deep integration). Plan for a dual-run period so you can validate parity before decommissioning.
On our developer-experience score, StackHawk is rated 5/5 and Checkmarx 3/5, so StackHawk edges ahead. Scores like this smooth over real differences in docs, CLI feel, and SDK quality, so treat them as a starting point. Spend an afternoon in each before relying on the number.
StackHawk is a reasonable alternative to Checkmarx when StackHawk fits marketplace, apps. If your use case matches Checkmarx's sweet spot — marketplace, apps — staying with Checkmarx is probably safer. Checkmarx itself is not meant for internal projects, which is often where users start shopping for alternatives.
