## What the models said for it

- "Kafka is the dominant default — it's been in production at massive scale for over a decade, has the largest ecosystem of connectors and tools" (DeepSeek V4 Flash, Streaming)
- "Apache Kafka - Open-source and free... highly scalable and widely used, making it ideal if you have technical expertise in-house." (Claude Haiku 4.5, Streaming)
- "Choose Confluent / Kafka if you are an enterprise building a broad, mission-critical real-time data architecture" (Gemini 3.5 Flash, Streaming)
- "Apache Kafka (Best Free Option) - Cost: Completely free (open-source) ... Industry standard, highly scalable" (Kimi K2, Streaming)

## And against it

- "Deprecated, being removed ... Kafka 4.0 (2025) removed ZooKeeper entirely." (Kimi K2, Streaming)
- "Kafka lacks built-in ETL capabilities like data transformation and loading... making it less suitable for simple ETL pipelines" (Claude Haiku 4.5, ETL)
- "While it's a popular and widely-used platform, it may not be suitable for small static websites or low-traffic applications." (Llama 4 Maverick, Streaming)
- "misconfigurations around idempotence, in-flight requests, and acknowledgments can cause ordering or delivery issues" (GPT-5.4 mini, Streaming)
