Language comparison
Key differences between Erlang and Gleam
| Characteristic | Erlang | Gleam |
|---|---|---|
| Syntax | Prolog-inspired, uses commas and periods to separate expressions, less familiar to most programmers. | Rust/Elm-like, more modern and familiar syntax, uses indentation and braces, easier to read for many developers. |
| Paradigm | Functional, concurrent, actor model, designed for distributed systems. | Functional, immutable data, compiles to Erlang VM, leverages actor model via BEAM. |
| Typing | Dynamically typed, no static type checking. | Statically typed, strong type inference, catches errors at compile time. |
| Performance | Highly performant for concurrent and distributed systems, mature VM (BEAM). | Similar performance to Erlang since it compiles to BEAM, but may have minor overhead due to abstractions. |
| Libraries and frameworks | Rich ecosystem, mature libraries and frameworks (e.g., OTP, Cowboy, RabbitMQ). | Can use Erlang/Elixir libraries via interop, but native Gleam libraries and frameworks are still growing. |
| Community and support | Large, established community, extensive documentation and support. | Smaller, newer community, growing support and documentation. |
| Learning curve | Steep, due to unique syntax and concurrency model. | Gentler, especially for those familiar with modern statically typed languages. |
Common questions
Frequently Asked Questions
How do I convert Erlang to Gleam?
Paste your Erlang code into the input box, confirm the languages are set to Erlang and Gleam, and click Convert. CodeConvert AI analyzes your Erlang code and generates equivalent Gleam code in seconds, preserving the original logic and structure.
What are the main differences between Erlang and Gleam?
Erlang and Gleam differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Erlang construct to its closest Gleam equivalent. See the comparison table below for the key differences between Erlang and Gleam.
Is the converted Gleam code accurate?
The AI produces high-quality Gleam code that preserves the behavior of your original Erlang code and follows Gleam conventions. It handles common patterns, data structures, and idioms for both Erlang and Gleam. For large or performance-critical code, review and test the Gleam output before using it in production.
Can I convert an entire Erlang project to Gleam?
You can convert Erlang files one at a time by pasting each file's code. For a full migration, convert each file and then review how classes, dependencies, and project structure map from Erlang to Gleam. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Gleam back to Erlang?
Yes. CodeConvert AI converts in both directions, so you can convert Gleam to Erlang just as easily using our Gleam to Erlang converter. Try the Gleam to Erlang Converter
Is the Erlang to Gleam converter free, and do I need to install anything?
Yes, it is free and runs in your browser with nothing to install and no IDE extension required. You can convert Erlang to Gleam without an account for up to 2 conversions per day. Sign in for free for higher limits.
What are the benefits of signing in?
Signing in unlocks CodeConvert AI's Pro converter with more powerful AI models, a built-in chat assistant, code execution, saved conversion history, and personal notes. Every free account includes 5 credits and supports up to 25,000 characters of input per conversion, with no credit card required.
