vLLM is a high-throughput, memory-efficient LLM inference engine with PagedAttention. The standard for self-hosted LLM serving with continuous batching and speculative decoding.
Reviewer scorecard
“The per-request pricing model is perfect for side projects — you literally pay nothing until you have traffic. Redis commands at $0.2/100K is incredibly cheap.”
“PagedAttention is a breakthrough for inference efficiency. The standard for production self-hosted LLM serving.”
“At high scale, per-request pricing can get expensive vs a fixed Redis instance. Know your traffic patterns. For most indie hackers and startups, it's a no-brainer.”
“If you're self-hosting LLMs, vLLM is the obvious choice. Battle-tested and actively maintained.”
“Upstash is doing for Redis what Neon did for Postgres — making it serverless-native. The QStash message queue is an underrated piece of the puzzle.”
“Self-hosted inference will remain important for latency, cost, and privacy. vLLM is the infrastructure layer.”
