Our verdict on Nimbalyst
Nimbalyst is a local visual workspace for teams and individuals working with Claude Code, OpenAI Codex, and other coding agents. Its diagram capabilities include AI-generated Mermaid diagrams, Mermaid import into editable diagrams, Excalidraw canvas editing, and data-model and ERD tools. The workspace also includes markdown, code, mockup, slide, spreadsheet, and CSV editors, plus task tracking, kanban boards, session management, and a terminal. Individual use is free, making it suited to product planners, developers, and small teams that want diagrams alongside project work.
The Individual plan costs $0 and includes the visual editor and workspace, AI-assisted editors, searchable session history, task management, a code editor and terminal, and mobile access for remote session and file management. The Teams plan adds real-time collaboration, shared markdown documents, mockups, Excalidraw, diagrams, trackers, kanban, and change history. It is listed at $20 per user per month or $200 per user per year, and the vendor says it is currently free during beta. Enterprise adds custom deployment and collaboration options, along with enterprise security and data-residency support.
Nimbalyst fits workflows that connect visual planning with coding-agent sessions. Integrations include Linear, GitHub, Slack, databases, and MCP servers, while export formats include Mermaid, Excalidraw, and Prisma schema. Desktop applications run on Windows, macOS, and Linux; the iOS companion supports session monitoring, file management, and change review. The desktop and iOS apps are MIT licensed. Choose Nimbalyst if your work benefits from diagrams, data models, tasks, and agent sessions in one workspace. A narrower diagram tool may be a better fit for users who do not need the surrounding planning and coding features.
