Phoenix Guide Best Hosting for Phoenix (2026)
Compare the best hosting platforms for Phoenix. We review Fly.io, Railway, and more with Elixir deployment patterns.
Phoenix applications benefit from platforms that support Elixir's BEAM VM. We've evaluated hosting options that handle Phoenix releases and clustering well.
Why This Matters
Phoenix and Elixir's BEAM VM enable powerful features like clustering and live updates. The right platform supports these features while simplifying deployment.
Key Considerations
BEAM Clustering
Elixir can cluster across nodes. Fly.io and some platforms support BEAM clustering for distributed features.
Mix Releases
Phoenix uses Mix releases for production. Compile on CI, deploy the release artifact.
LiveView WebSockets
LiveView needs WebSocket support. Most modern platforms handle this well.
Hot Code Upgrades
Elixir supports hot code upgrades, but most deployments use rolling restarts instead.
Health Checks
Use Phoenix health check plugs. Configure platform to check /health endpoint.
