+
+## Generating AsyncAPI Documents
+
+Event-driven architectures (EDA) have become a cornerstone of modern software systems, enabling organizations to build responsive, scalable, and loosely coupled applications. At the heart of these architectures lies the need for clear, precise communication between services, often represented by AsyncAPI documents.
+
+To generate AsyncAPI documents, we have the following options:
+* _**Hand Coding**_ - Many teams still manually write AsyncAPI documents in YAML/JSON, especially smaller teams or projects with simple requirements.
+* _**Code-First Tools**_ - Tools like the AsyncAPI Generator and SDKs (e.g., Java, Node.js libraries) enable teams to generate AsyncAPI documents from existing codebases. 
+* _**Design-First Platforms**_ - Tools and Platforms that provide graphical interfaces to design events visually. These tools generate AsyncAPI documents automatically, reducing manual effort.
+
+This blog focuses on tools that support a design-first approach to building event-driven applications and APIs, especially in generating AsyncAPI documents. While tools like Stoplight Studio and AsyncAPI Studio are valuable, there's potential for a more engaging experience that brings in visualization, discovery and collaboration into the play. 
+
+### Hand Coding
+Creating AsyncAPI documents by hand may seem manageable for small, simple systems, but it quickly becomes unwieldy as complexity grows. 
+|  |  |
+|---|---|
+| **Issues** | _**Error-Prone:**_ High risk of syntax errors, omissions, and inconsistencies in YAML/JSON documents.<br/>_**Time-Consuming:**_ Requires meticulous work, especially for large or complex systems.<br/>_**Hard to Scale:**_ Becomes unmanageable as the architecture grows in size and complexity.<br/>_**Limited Collaboration:**_ Non-technical stakeholders find it difficult to contribute or understand. |
+| **Advantages** | _**Full Control:**_ Provides complete freedom to define the AsyncAPI document exactly as needed.<br/>_**Tool Independence:**_ No reliance on external platforms or tools.<br/>_**Flexibility**_: Can be used for unique, non-standard implementations. |
+| **Disadvantages** | _**Lacks automation**_, increasing manual effort and maintenance overhead.<br/>_**Difficult to**_ maintain versioning or handle evolving systems effectively. |
+### Code-First Tools
+The code-first approach generates AsyncAPI documents directly from the application code. It is commonly used in projects with existing implementations, ensuring alignment between the documentation and the codebase.
+
+|  |  |
+|---|---|
+| **Issues** | _**Tight Coupling with Code:**_ AsyncAPI documents depend heavily on the implementation, making it harder to iterate or plan without writing actual code.<br/>_**Limited Flexibility:**_ Adapting to design changes requires updates to the codebase, which can slow down the process.<br/>_**Lacks Early Collaboration:**_ Non-technical stakeholders are often excluded until the implementation is done. |
+| **Advantages** | _**Faster for Existing Codebases:**_ AsyncAPI documents can be automatically generated from code, reducing manual work.<br/>_**Consistency:**_ Documents are tightly aligned with the implementation, ensuring they remain up-to-date.<br/>_**Integration-Friendly:**_ Works well with CI/CD pipelines to generate and validate documents during the build process. |
+| **Disadvantages** | _**Suited for teams with existing codebases**_ but less effective for greenfield projects or evolving architectures.<br/>_**Can create dependency**_ between documentation and code quality, leading to inaccuracies. |
+
+### Design-First Platforms
+The design-first approach focuses on defining AsyncAPI documents before writing any code. It emphasizes planning and collaboration, leveraging tools to visually design and generate documentation, which guides the development process.
+|  |  |
+|---|---|
+| **Issues** | _**Learning Curve:**_ Tools for design-first approaches (e.g., Solace Event Portal, AsyncAPI Studio) may have a learning curve for new teams.<br/>_**Initial Setup Effort:**_ Requires upfront investment in tooling and training before generating useful documentation.<br/>_**Tool Dependence:**_ Reliance on specific platforms can create vendor lock-in. |
+| **Advantages** | _**Collaborative:**_ Promotes early collaboration between technical and non-technical stakeholders.<br/>_**Visualization:**_ Tools often provide visual interfaces for designing events, schemas and event flows.<br/>_**Planning-Friendly:**_ Useful for defining event-driven architectures before implementation begins.<br/>_**Consistency and Reuse:**_ Encourages standardization and reuse of events across teams. |
+| **Disadvantages** | _**Requires**_ clear communication across teams to translate designs into implementations effectively.<br/>_**May not align**_ well with teams who prefer an iterative, code-driven development style. |
+
+Design, Discovery, Reuse, Collaboration, and Cataloging are essential for building robust asynchronous applications. A well-thought-out design establishes clear architecture, improving scalability and reliability. Collaboration encourages alignment across teams, minimizing miscommunication. Cataloging API documentation ensures easy access, consistency, and reuse, streamlining development across projects.
+
+Enter [**Event Portal**](https://solace.com/what-is-an-event-portal/) from [**Solace**](https://solace.com/) — a tool designed to address these complexities while empowering teams to fully embrace the potential of EDA.
