Davia.ai is a new tool aimed at Python developers who want to quickly turn their functions, particularly for AI applications, into web apps. Frustrated with the limitations of Streamlit and Gradio regarding flexibility and polish, the Davia team built a platform where developers decorate Python functions, which then generates a FastAPI server and UI based on prompts. This allows for more complex and customizable interfaces built using React best practices. The Hacker News thread reveals initial user feedback. Concerns were raised about autoplaying videos on the website, which were addressed by replacing the video with a GIF. Questions were also asked about the underlying HTTP request methods and the choice of POST over GET, which the developers clarified as a simplification for users unfamiliar with FastAPI, while still allowing for custom endpoints. A suggestion was made to offer a standalone edge function service. Others requested more details on how Davia distinguishes itself from Streamlit and Gradio, leading to a discussion about UI customization, production limitations, and state management. Finally, signup is required to view use case examples, with the team planning to display these on the site directly in the future.
