- Multi-file vulnerability patching
- Parametric SQL injection fixes
- Auth, billing, tenant, webhook reasoning
Free vs Pro
Pay for deeper reasoning, not basic safety
The free engine handles offline AST scanning and standard structural remediations. Pro unlocks the premium Deep Reasoning Pipeline.
- Free CLI remains useful by itself
- Pro extends, not replaces, the local engine
- Invite-only beta onboarding today
Pricing
Choose the path that matches your remediation depth: free local AST, solo Pro, or team rollout.
The free CLI stays useful on its own. Paid plans unlock the Deep Reasoning layer, secure proxy-backed fixes, and higher-touch onboarding. During beta, Solo and Teams access both start through the waitlist.
