Which one to pick

Pick anti-slop if…

Easy setup — one-command picker or a single-file install drops a portable, non-prescriptive filter into many coding agents so you can stop AI 'slop' fast.

  • Model freedom: Any agent / BYOK (5/5 against 1/5)
Runs in cli, coding-agent-plugin, ide. Works with byok.

Pick numbat if…

Privacy-first — runs detection and rule evaluation on-device with a single-binary distribution, enabling monitoring and optional pre-action blocking without mandatory third-party services.

  • Customization: Custom YAML rules (5/5 against 3/5)
Runs in cli, ide, coding-agent-plugin. Works with other-fixed.
