## Warned against

- Jenkins: 33 of 62 labels negative. "Why Avoid: It slows down developer velocity because developers wait on operations teams to manage infrastructure rather than writing code." (Qwen 3.7 Flash, negative prompt)
- CircleCI: 20 of 45 labels negative. "Why to avoid: ... CircleCI's cloud offering uses per-minute/credit billing, which can result in unpredictable and escalating costs" (Mistral Small, negative prompt)
- GitHub Actions: 18 of 65 labels negative. "GitHub Actions and CircleCI are not recommended for large enterprises due to their per-minute/credit billing that scales linearly" (Llama 4 Maverick, negative prompt)
- GitLab CI/CD: 10 of 76 labels negative. "GitLab self-managed, Jenkins, and other self-hosted systems can make sense when control is essential—but they transfer more responsibility" (GPT-6 Luna, negative prompt)
