Best For
Run containers close to users globally — best for latency-sensitive agent APIs and real-time agent interactions
Best-in-class Next.js hosting with Vercel AI SDK — the default for deploying AI-powered frontend apps
Limitations
Steeper learning curve than Railway; pricing can be unpredictable with auto-scaling; smaller community; documentation is sometimes sparse
Vendor lock-in on serverless primitives; cold starts on serverless functions; expensive at scale for compute-heavy AI workloads; free tier has bandwidth limits
