Key differences between Gleam and Erlang

CharacteristicGleamErlang
SyntaxModern, ML-inspired, statically-typed syntax with clear structure and readability.Prolog-like, dynamically-typed syntax that can be unfamiliar and terse for newcomers.
ParadigmFunctional, with strong emphasis on immutability and purity.Functional, with focus on concurrency, fault-tolerance, and message passing.
TypingStatically typed with a strong, sound type system and type inference.Dynamically typed with optional type specifications (Dialyzer) but no enforced static types.
PerformanceCompiles to efficient BEAM bytecode, similar performance to Erlang for most use cases.Native to the BEAM VM, highly optimized for concurrency and low-latency systems.
Libraries and frameworksSmaller ecosystem, can use Erlang and Elixir libraries via interop, but fewer native Gleam libraries.Mature ecosystem with many libraries and frameworks, especially for telecom and distributed systems.
Community and supportGrowing but small community, active development, less corporate backing.Large, established community with decades of production use and strong industry support.
Learning curveGentler learning curve for those familiar with modern typed functional languages.Steeper learning curve due to unique syntax and concurrency model.
