Fault-tolerant by design
Supervisors restart what fails, so one bad request never takes the whole system down.
Why teams pick Elixir
Built on 30+ years of telecom-grade engineering.
Elixir runs on the Erlang VM, the BEAM, originally built to keep phone switches online. Modern syntax, battle-tested runtime.
Concurrency that scales
Millions of lightweight processes spread across every core, and across machines, without locks.
Real-time, out of the box
Phoenix Channels and LiveView ship interactive, live-updating apps with far less JavaScript.
A joy to maintain
Immutable data, pattern matching and first-class tooling keep large codebases readable for years.
Browse by industry
Not just a startup language.
