Blueberry vs OnUml
Side-by-side comparison to help you choose the right AI tool.
Blueberry
Blueberry is an all-in-one Mac app that unifies your editor, terminal, and browser for seamless web app development.
OnUml
OnUML uses AI to instantly create UML diagrams from your natural language descriptions or Mermaid code.
Feature Comparison
Blueberry
Integrated Workspace
Blueberry combines a code editor, terminal, and preview browser into one cohesive environment. This integration allows developers to work more efficiently without the constant need to switch between different applications, enhancing focus and productivity.
Live Context with AI
The platform's built-in MCP server enables AI models to access your entire workspace. This means your AI can see open files, terminal output, and running applications, giving it the full context needed to assist you effectively, whether it's answering questions or suggesting code snippets.
Preview Across Devices
Blueberry comes equipped with built-in desktop, tablet, and mobile view previews. This feature allows you to see exactly how your application will look across different devices, ensuring a consistent user experience without leaving the Blueberry workspace.
Pinned Apps and Customization
You can keep essential tools like GitHub, Linear, Figma, and PostHog docked within your workspace. These pinned apps load with your project and share live context with your AI, allowing for a more integrated and efficient workflow. Additionally, you can customize your workspace setup per project, saving time and effort.
OnUml
AI Smart Chat
This is the star feature of OnUml. Instead of memorizing complex Mermaid syntax, you can describe your diagram needs in natural language. For example, you can type "Create a sequence diagram for a user login process with a database check" and the AI will generate the corresponding, syntactically correct Mermaid code for you. It acts as your intelligent design partner, translating your ideas into a structured diagram format instantly, which is perfect for brainstorming or quick documentation.
Live Diagram Rendering & Preview
As you type in the Mermaid editor or receive code from the AI chat, a live preview pane updates in real-time. This WYSIWYG (What You See Is What You Get) experience allows for immediate feedback. You can see exactly how your diagram will look as you build it, making it incredibly easy to spot errors, adjust layouts, and iterate on your design without any frustrating back-and-forth between coding and viewing.
Built-in Mermaid Editor with Smart Hints
For users who prefer direct control or want to fine-tune the AI's output, OnUml provides a clean, minimalist code editor dedicated to Mermaid syntax. It includes smart code hints and automatic syntax fixes to help you write valid code faster. This feature is ideal for learning Mermaid or for making precise adjustments to complex diagrams that require a developer's touch.
Diagram Export and Organization
Once your diagram is perfect, OnUml lets you export it in high-quality formats like PNG and SVG, making it simple to share in documentation, presentations, or reports. The platform also emphasizes ease of use with code saving and organization features, allowing you to keep your projects tidy and accessible for future edits, all without requiring any user registration.
Use Cases
Blueberry
Streamlined Development
Developers can use Blueberry to streamline their coding process by having access to their terminal, code editor, and browser in one workspace. This allows for quick edits, testing, and debugging without losing focus or context.
Collaborative Product Building
Product teams can collaborate more effectively by using Blueberry's integrated features. The ability to share live project contexts with team members and AI assistants enhances communication and collaboration, leading to better product outcomes.
Rapid Prototyping
Designers and developers can quickly prototype applications using Blueberry's live preview feature. By seeing changes in real-time across different devices, teams can iterate faster and make informed design decisions, ultimately speeding up the development cycle.
Enhanced Learning and Experimentation
For those learning to code or experimenting with new technologies, Blueberry offers an intuitive environment where users can easily test out code snippets and receive AI-assisted guidance. This feature helps new developers to learn through practice while maintaining an organized workspace.
OnUml
Software Architecture Documentation
Developers and architects can quickly draft and iterate on system design diagrams, such as class diagrams, component diagrams, or deployment diagrams. By describing the system components and their relationships to the AI, they can generate visual documentation that is essential for team alignment and technical specs, speeding up the design phase significantly.
Creating Technical Tutorials and Guides
Technical writers and educators can use OnUml to effortlessly generate flowcharts and sequence diagrams to embed in tutorials, blog posts, or course materials. The AI chat simplifies the process of creating clear, visual explanations of complex processes, making technical content more engaging and easier for readers to understand.
Planning and Visualizing Workflows
Project managers and analysts can map out business processes, user journeys, or algorithm flows. By conversing with the AI to create activity diagrams or flowcharts, they can visualize steps, decision points, and outcomes, which is invaluable for process optimization, onboarding, and team discussions.
Rapid Prototyping and Brainstorming
During planning meetings or brainstorming sessions, teams can use OnUml in real-time to visualize ideas. Instead of sketching on a whiteboard, they can type a prompt like "show a user signing up, verifying email, and accessing a dashboard" and immediately get a shareable, professional diagram to center the discussion and capture decisions.
