Reviewer scorecard
“For apps that need full server control — WebSocket servers, background workers, AI inference — Fly.io gives you the flexibility that serverless platforms don't.”
“Cheapest way to run Llama and Mistral models in production. The inference speed is competitive with major providers. OpenAI-compatible API makes switching easy.”
“The DX has improved massively but it's still more complex than Vercel. You need to understand Docker and infrastructure. Not for beginners.”
“The pricing is genuinely good and reliability has improved. The fine-tuning workflow is straightforward. A solid choice for open-source model deployment.”
“Fly.io is the answer for workloads that don't fit the serverless model. As AI inference goes local-first, having servers in 30+ regions matters.”
“Together is betting that the future is open-source models. As Llama and Mistral improve, inference providers like Together become the AWS of AI.”
