Best For
Run containers close to users globally — best for latency-sensitive agent APIs and real-time agent interactions
One-click deploy for any language/framework — best for long-running agent processes that don't fit serverless constraints
Limitations
Steeper learning curve than Railway; pricing can be unpredictable with auto-scaling; smaller community; documentation is sometimes sparse
Smaller ecosystem than Vercel/Netlify; less mature CDN and edge story; costs can surprise with always-on containers; no built-in AI tooling
