Fly.io vs Gigalixir

Why the models rank Fly.io — on best paas platforms for hosting elixir phoenix applications

“The closest thing to a Phoenix-native PaaS — first-class support for BEAM clustering (libcluster works out of the box via internal 6PN networking), global multi-region deploys that pair naturally with Phoenix LiveView and Fly.Postgres, and a documented partnership with the Phoenix core team (Chris McCord's official deploy guides target it). Fly Machines give fast-booting Firecracker VMs and easy horizontal scaling of distributed nodes. FIX: Operationally rawer than a fully-managed PaaS — you own more of the reliability story (past platform-wide outages, self-managed Postgres unless you pay for managed), so it's not for teams wanting hands-off stability.”

“Purpose-built for Phoenix: automatic BEAM clustering and node discovery, long-lived connections, zero-downtime rollback-capable deploys, Remote Observer/IEx, and managed PostgreSQL. It narrowly beats Fly.io assuming the typical team values minimal operations over global reach.”
