Leverage the benefits of contract-driven development to speed up the creation and deployment of your microservices and micro frontends with assurance. By adopting a left-shift strategy and eliminating the reliance on conventional integration tests, you can employ API specifications as actionable contracts that highlight compatibility issues among your microservices early on in the development cycle. This methodology facilitates simultaneous development, drastically cutting down cycle times and empowering you to introduce products to the market faster than ever. As integration testing progresses, the likelihood of encountering integration challenges is significantly diminished, resulting in a smoother, more resilient, and efficient workflow. Encourage teamwork between your frontend and backend teams by effortlessly aligning on API designs and specifications. Quickly convert your API specifications into tests without incurring additional costs or writing any code, allowing you to run them against your services to proactively identify integration issues. Furthermore, our cutting-edge “no code” technique enables you to detect backward-incompatible changes simply by comparing two versions of the API specification, which further streamlines your development process. This approach not only improves collaboration among team members but also fosters a more nimble and adaptable development ecosystem, ultimately enhancing the overall quality of your projects. With these tools at your disposal, you can ensure that your development team is always aligned and ready to tackle new challenges effectively.

Flowcode combines the simplicity of visual programming with the powerful functionality of conventional coding, allowing users to swiftly create applications while overseeing the essential infrastructure. This integration helps developers focus on resolving intricate logical problems. Featuring a user-friendly drag-and-drop interface, the platform provides robust logic-driven nodes that simplify the process of visually tracing API calls, which aids in faster bug identification. In addition, Flowcode supports easy management of versions, rollbacks, and updates, ensuring a smooth user experience throughout. The platform also allows for the integration and orchestration of multiple AI models, enabling the development of customized AI APIs. Built on Flyde, which is an open-source visual programming language, Flowcode works within VS Code and integrates seamlessly with existing TypeScript code, web browsers, and Node.js environments. Users can tackle simple tasks using visual flows while exploring complex logic through custom code nodes. Furthermore, it offers options for exporting data and APIs for deployment on private servers, providing both independence and flexibility. Managing database tasks is simplified with abstracted PostgreSQL connections, and users have the capability to connect to other databases to meet specific needs, creating a dynamic programming environment. Ultimately, the synergy of these features empowers users to enhance their creativity and optimize their workflows in an effective manner. This comprehensive approach ensures that developers can adapt to changing requirements while maintaining high productivity levels.
