## Warned against

- Bloomreach Discovery: 15 of 43 labels negative. "enterprise-focused, custom pricing almost always $1,000+/month" (DeepSeek V4 Flash, budget prompt)
- Algolia: 12 of 63 labels negative. "Be terrified of consumption-based pricing (Algolia and Coveo both have "cliff" pricing models that blow up as you grow)." (DeepSeek V4 Flash, negative prompt)
- Klevu: 7 of 43 labels negative. "Klevu's G2 review sample is very small, so individual complaints—including one about renewal terms—aren't enough to establish a general pattern" (GPT-6 Luna, negative prompt)
- Constructor: 9 of 37 labels negative. "one source says to skip it if you need self-service signup, published pricing, or a free tier, because evaluation runs through sales." (Perplexity Sonar, negative prompt)
