What programming languages does AWS Lambda support?

AWS Lambda supports multiple programming languages, allowing developers to use the language they are most comfortable with. AWS provides native support for some languages and also allows for custom runtimes to support others.

Natively Supported Languages
  1. 1

    JavaScript (Node.js)

  2. 2

    Python

  3. 3

    Java

  4. 4

    Go

  5. 5

    C# (.NET Core)

  6. 6

    Ruby

Other Supported Languages (via Custom Runtime)
  1. 1

    PHP

  2. 2

    Rust

  3. 3

    C++

  4. 4

    Elixir

  5. 5

    Swift

  6. 6

    Any other language (with proper custom runtime configuration)

With the help of Lambda’s custom runtime feature, you can bring virtually any language to AWS Lambda by implementing the appropriate API interface using the Lambda Runtime API.

Choosing the Right Language Depends On
  1. 1

    Performance requirements

  2. 2

    Startup latency (cold start time)

  3. 3

    Library and framework availability

  4. 4

    Developer expertise

In most cases, Node.js and Python are preferred for their fast startup times and rich ecosystem of libraries, especially for event-driven or API-based workloads.
