Apicurio No Code API Builder

Apicurio is an open-source API design platform that aids in creating, editing, and managing API designs. The tool’s primary function is to provide a user-friendly environment for designing API specifications with support for both OpenAPI and AsyncAPI standards.

Key Features

  • Web-Based Design: Apicurio Studio operates entirely in a web browser, eliminating the need for any additional installations. The platform offers flexibility in configuring deployment platforms, data storage, and authentication settings.
  • Code-Optional Design: Catering to users who might not be entirely familiar with the intricacies of OpenAPI or AsyncAPI specifications, Apicurio Studio simplifies the process. Users can easily validate their API content and even have the option to generate a Java project directly from their OpenAPI design.
  • Open Source: Being open-source is one of Apicurio Studio’s key strengths. Hosted and actively maintained on GitHub, it encourages community contributions. Furthermore, it integrates seamlessly with other version control platforms like GitLab and Bitbucket for robust API source control and publishing.

Use Cases

  • For users seeking a visual interface to design APIs without getting involved in the complexities of coding.
  • Organizations looking for an open-source API design tool with the flexibility of web-based access.
  • Developers or teams wanting a streamlined way to validate API content and produce Java projects from API designs.

Pros and Cons


  • Intuitive user interface makes it easy for users of all levels to design APIs
  • Web-based functionality allows users to design APIs from anywhere without any setup.
  • Open-source nature provides flexibility and ensures constant updates from the community.
  • Integrated with major source control platforms for a seamless workflow.


  • Being an open-source tool, commercial support might be limited compared to enterprise solutions
  • The platform might have a steeper learning curve for users not familiar with API design principles


Since Apicurio is open-source, it is available for free. Users can download and host it on their servers.

User Experience

Thanks to its browser-based design, Apicurio Studio offers a smooth user experience. The interface is clean and intuitive, even for those unfamiliar with API design concepts. The code-optional design further ensures that users can get their work done without any unnecessary technical hurdles.

Customer Support

Being an open-source project, Apicurio’s primary support channel is its community. This means users can access forums, GitHub repositories, and community chat channels for assistance. However, response time or quality of assistance might not be as consistent as with commercial tools.

Security and Reliability

Since it is self-hosted, organizations have control over the security and reliability of their Apicurio installations. However, as with all open-source tools, it is essential to keep the software updated to the latest version to ensure you are protected against any known vulnerabilities.
