Gleam is a statically typed, functional programming language that compiles to Erlang and runs on the BEAM virtual machine. It ships with a built-in compiler, build tool, package manager, formatter, and language server, and interoperates with Erlang and Elixir packages.

Use cases

• build type-safe scalable backend services on the Erlang VM
• learn a statically typed functional programming language
• write concurrent fault-tolerant systems with millions of green threads
• interoperate with existing Erlang and Elixir packages
• create a new web service project with a modern toolchain
• migrate from Elixir or Erlang to a type-safe language

When to choose

• you want BEAM reliability and concurrency with a strong static type system
• you need no null values, no exceptions, and clear compiler error messages
• you want an all-in-one toolchain with compiler, build tool, and formatter included
• you are building planet-scale services like WhatsApp-style workloads

When to avoid

• you need a mature ecosystem with decades of libraries and hiring pool
• your team depends on tooling outside the BEAM ecosystem
• you need low-level systems programming or direct hardware control
• you require languages with guaranteed long-term corporate backing
