Supported Languages & Tech Stacks

Our API is language-agnostic and works with any backend or frontend stack that can make HTTP requests.

Below are commonly used environments where customers integrate validation and alias detection:

Backend / Server​

  • Node.js
  • JavaScript
  • Python
  • Go
  • PHP
  • Ruby
  • Java
  • C# / .NET
  • Rust

Universal Support​

Since CheckEmail.dev conforms to standard REST principles and returns JSON, you can use any HTTP client (like curl, axios, requests, guzzle, etc.) to interact with our endpoints.

Security Note

If you are integrating with a Frontend framework (React, Vue, etc.), remember to route requests through your own backend or a serverless function to keep your API Key secret.
