[54] / VIBEEVAL VS STEPSECURITY /$49/MO VS ENTERPRISE

StepSecurity Alternative - VibeEval Comparison

StepSecurity (stepsecurity.io) hardens the pipeline AI agents use - dev machines, npm registry, GitHub Actions runners. VibeEval verifies the application those pipelines produce. Both layers matter; they don't substitute.

TL;DR: StepSecurity is enterprise supply chain security covering the dev machine, npm packages, and CI/CD. VibeEval is the runtime application security for whatever the pipeline shipped. Different problems. Run StepSecurity if you're worried about Shai-Hulud-class npm attacks; run VibeEval to know the app you shipped is safe.

Dev Machine Guard + npm Cooldown + Harden-Runner

Where StepSecurity Wins

  • Battle-tested supply chain detection (caught tj-actions and Shai-Hulud early)
  • Cooldown policies block npm packages before community vetting completes
  • Harden-Runner provides runtime visibility into GitHub Actions
  • Org-wide visibility into AI agent and MCP usage on dev machines

Where StepSecurity Falls Short for App-Layer Security

NOT AN APP SCANNER

Protects the pipeline, not the app. Whether your Lovable + Supabase app leaks user data is outside scope.

NO DAST

Cannot exercise the deployed app to confirm exploits.

ENTERPRISE-PRICED

Demo-led pricing. Wrong shape for solo founders.

NO IDOR / RLS

Application-layer authorization is not in the supply chain layer.

When to Pick StepSecurity

  • Enterprise org with a real npm supply chain attack surface
  • You run AI agents inside GitHub Actions with privileged secrets
  • You need org-wide visibility into IDE extensions / MCP servers
  • Compliance requires runtime CI/CD monitoring

When to Pick VibeEval

  • You ship vibe-coded apps and need application-layer verification
  • Your bigger risk is RLS misconfiguration, not npm supply chain
  • You’re solo or small team and need flat $49/mo pricing

Best Together

StepSecurity protects the pipeline. VibeEval verifies what came out of it. Enterprise teams that take vibe coding seriously usually run both.

Common questions

What does StepSecurity actually protect?
Three layers: (1) Dev Machine Guard inventories AI agents, MCPs, IDE extensions, and locally installed npm packages. (2) NPM Cooldown blocks newly published packages until they're vetted. (3) Harden-Runner monitors GitHub Actions network behavior and blocks unauthorized egress.
Does StepSecurity test my deployed app?
No. The whole platform sits upstream of the deployed app. Whether your shipped Lovable + Supabase app has IDOR, missing RLS, or exposed keys is outside scope.
Why pick VibeEval if I have StepSecurity?
Because they protect different things. StepSecurity protects how your code is built and shipped. VibeEval verifies what shipped is actually safe to use. Both matter for production.
