Founded in 2017, http4k has grown into one of the most popular HTTP libraries for Kotlin, reflecting over 15 years of combined experience in server-side development. Our mission was to create a library that embodies simplicity and clarity, enabling developers to build robust applications without the complexities often associated with traditional frameworks.

With it’s uniform HTTP client/server model, http4k occupies a unique space within the Kotlin ecosystem and emphasizes functional principles, immutability, minimal dependencies and a focus on test-driven design. Today, http4k boasts over 100 integrations and is utilized worldwide to power applications of all sizes.

http4k Limited is a UK-based company that provides consulting services, training, and support for global clients of all sizes that use http4k to power their applications.

We’re always looking to connect with organisations and engineers who are as passionate about delivering quality-driven solutions as we are. Collaboration is at the heart of our ethos, and we believe that by working together, we can push the boundaries of what’s possible in the Kotlin ecosystem. If you’re interested in sharing ideas, contributing to http4k, or exploring how we can work together on innovative projects, we’d love to hear from you!
