Hi, DevHunt_ community! Hubql’s goal is to address key collaboration challenges in software development. Similar to how Figma revolutionized design, we are changing how data models and APIs are built. Today, we are launching our initial version of Hubql OpenAPI support for collaboration, visualization, and documentation. Automatically generate visualization for your OpenAPI schemas. Collaborate with team members and external partners in real-time or asynchronously to streamline interactions, eliminate misunderstandings, and boost productivity. Additionally to OpenAPI support, we support five static file types, with more to be added soon: - JSON - XML - Prisma - Protobuf - GraphQL We combine automated code visualization with collaboration features such as commenting, mentions, suggestions, and sharing with your team members or external partners. Our tool offers a creative and collaborative experience iterating over your data models and APIs. We are also proud that Hubql is fully integrated into your Git workflow! Use Hubql’s GitHub app to produce the latest documentation for every pull request. Besides, Hubql pushes any update back into GitHub via pull requests. You can try Hubql today by visiting our website and get started: https://www.hubql.com/ We recommend starting your Hubql experience from one of these starting points: - Use Hubql CLI to connect your local files to our platform - Connecting an existing GitHub repository, - Visualize your API schema or data model and share it with your peer Thank you for your feedback and for helping us to make the software more collaborative. We are happy to answer any questions and work with you to improve Hubql!

- Schema Visualizer vs Sideko: Focuses on generating SDKs and docs for APIs rather than visual diagram collaboration
- Schema Visualizer vs WunderGraph: Provides instant GraphQL APIs and composable back-ends, not visual schema editing
- Schema Visualizer vs Hookdeck: Acts as an event gateway for event-driven apps, unrelated to schema visualization
- Schema Visualizer vs Keel: Offers backend infrastructure and team tools but lacks built-in schema diagramming
