What It Is

Eyeal is positioned as a centralized chart management and interactive editing tool for developers. It focuses on the problem that Mermaid diagrams are often scattered across repositories, documentation, and AI agents without a unified way to manage them. It can ingest Mermaid blocks from Markdown, .mmd files, or editor input, converting Mermaid/ASCII into interactive diagrams that can be dragged, shared, and exported. It also claims support for history and version control.

Core Capabilities

Its main selling point is a Rust WASM engine: according to the official website, Dagre has been ported to Rust and compiled to WASM, enabling sub-10ms layout calculations. On the interaction side, users can drag nodes directly, while edges are recalculated in real time using A* routing. Diagram coverage is broad, including Mermaid-style diagrams, metrics charts, observability diagrams, and specialized diagrams such as flowcharts, Gantt charts, sequence diagrams, Kanban boards, flame graphs, service topologies, Sankey diagrams, and Heatmaps. The platform also offers 10 types of flow animations, PNG/PDF export, link sharing, and plans to support Web, desktop via Tauri, and mobile.

Pricing and Commercialization

The free plan is aimed at individuals, students, and open-source projects. It includes unlimited documents, all diagram types, interactive editing, animations, watermark-free PNG export, and 10 AI interactions per month, making it fairly cost-effective. Pro costs 9€/month and adds vector PDF export, more AI interactions, custom presets, and priority rendering. Team costs 25€/user/month and provides real-time collaboration, shared workspaces, 1,000 API calls per month, bulk export, and custom branding. The Enterprise plan mentions SSO, on-premise deployment, and SLA, but requires contacting the company.

Pros and Cons

Its strengths are that it fits closely into developer documentation workflows, offers a short path from Mermaid/ASCII to interactive diagrams, supports a wide range of diagram types, and has relatively generous limits on the free plan. It also points toward AI-oriented workflows with features such as an MCP server and AI patching. The drawbacks are also clear: the site repeatedly shows “Launch/App Soon,” so actual availability is uncertain; public details are lacking on whether it is open source, data security, API documentation, SDKs, and payment methods; and its performance claims and comparisons with competitors mainly come from the official site and still need independent testing.

Who It’s For and Access from China

Eyeal is suitable for developers, architects, consultants, and engineering teams that frequently maintain Mermaid diagrams in Markdown, repositories, and technical documentation. If you only create diagrams occasionally, Mermaid.live, Draw.io, or Excalidraw are still more mature options; if you need enterprise-grade flowchart collaboration, Lucidchart is worth comparing. Access from China is not covered in the available text, so network connectivity, euro-denominated payment availability, and enterprise procurement support all need to be verified in practice.
