Language comparison
Key differences between Gleam and Erlang
| Characteristic | Gleam | Erlang |
|---|---|---|
| Syntax | Modern, ML-inspired, statically-typed syntax with clear structure and readability. | Prolog-like, dynamically-typed syntax that can be unfamiliar and terse for newcomers. |
| Paradigm | Functional, with strong emphasis on immutability and purity. | Functional, with focus on concurrency, fault-tolerance, and message passing. |
| Typing | Statically typed with a strong, sound type system and type inference. | Dynamically typed with optional type specifications (Dialyzer) but no enforced static types. |
| Performance | Compiles 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 frameworks | Smaller 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 support | Growing but small community, active development, less corporate backing. | Large, established community with decades of production use and strong industry support. |
| Learning curve | Gentler learning curve for those familiar with modern typed functional languages. | Steeper learning curve due to unique syntax and concurrency model. |
Common questions
Frequently Asked Questions
How do I convert Gleam to Erlang?
Paste your Gleam code into the input box, confirm the languages are set to Gleam and Erlang, and click Convert. CodeConvert AI analyzes your Gleam code and generates equivalent Erlang code in seconds, preserving the original logic and structure.
What are the main differences between Gleam and Erlang?
Gleam and Erlang differ in syntax, type system, standard libraries, and common idioms, so copying code line for line usually will not compile. The converter maps each Gleam construct to its closest Erlang equivalent. See the comparison table below for the key differences between Gleam and Erlang.
Is the converted Erlang code accurate?
The AI produces high-quality Erlang code that preserves the behavior of your original Gleam code and follows Erlang conventions. It handles common patterns, data structures, and idioms for both Gleam and Erlang. For large or performance-critical code, review and test the Erlang output before using it in production.
Can I convert an entire Gleam project to Erlang?
You can convert Gleam 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 Gleam to Erlang. Signing in for free raises the input limit to 25,000 characters per conversion for larger files.
Can I convert Erlang back to Gleam?
Yes. CodeConvert AI converts in both directions, so you can convert Erlang to Gleam just as easily using our Erlang to Gleam converter. Try the Erlang to Gleam Converter
Is the Gleam to Erlang 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 Gleam to Erlang without an account for up to 5 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.
