Why engineers want more than Mermaid

Mermaid.js is the most popular diagram-as-code format. It renders natively on GitHub, GitLab, Notion, and most Markdown platforms. For developers, it's the natural choice for embedding diagrams in documentation.

But Mermaid has limits. You still need to learn the syntax — each diagram type has different notation. The mermaid.live editor is basic with no AI assistance. Some diagram types (deployment, complex component diagrams) aren't well supported. And there's no brainstorming or architecture workflow.

Cybewave Studio makes Mermaid accessible to everyone. Describe your diagram in plain English, get valid Mermaid code, preview it instantly, and refine with AI. When Mermaid falls short, switch to PlantUML — both formats in one editor. Plus AI architecture brainstorming that generates multi-diagram architectures from system descriptions.

Mermaid diagram types Cybewave generates

Every Mermaid diagram type, generated from plain English.

Flowcharts

Decision trees, process flows with graph TD/LR syntax. Subgraphs, styling, and conditional branching.

Sequence diagrams

API flows, auth handshakes, distributed transactions. Lifelines, activations, notes, and loops.

ER diagrams

Database schema with entity-relationship notation. Tables, columns, primary/foreign keys, cardinality.

Class diagrams

Object-oriented design with classes, interfaces, inheritance, composition, and associations.

C4 diagrams

C4Context, C4Container, C4Component views. Structured multi-level architecture diagrams.

State diagrams

State machines, transitions, guards, and composite states. Ideal for modeling application behavior.

Gantt charts

Project timelines, task dependencies, and milestones. Useful for sprint planning and roadmaps.

Git graphs

Branch visualization, merge flows, and commit history. Document branching strategies.

What Cybewave generates

Describe "user authentication flow" → get Mermaid code instantly.

Input — Plain English

What you describe

"Show the user authentication flow: user enters email and password, API validates credentials, checks the database, returns a JWT token, and the client stores it."

Output — Mermaid Code

Choose your workflow

✓

I already use Mermaid

Cybewave is a better Mermaid editor. AI assists with complex syntax, live preview is built-in, and you can also use PlantUML when Mermaid falls short.

✓

I want to start with Mermaid

Skip the syntax learning curve. Describe your diagram in English and the AI generates valid Mermaid code. Learn the syntax naturally by reading the output.

✓

I need Mermaid in my README

Generate Mermaid code in Cybewave, copy to your GitHub/GitLab README. It renders natively — no image files or external services.

✓

I need more than Mermaid

Some diagrams (deployment, complex component) are better in PlantUML. Cybewave supports both — use the right format for each diagram.
