# Excaliwow

> Excaliwow is a hosted, real-time Excalidraw workspace with a developer platform: control your diagrams from the CLI, the REST API, or an AI agent over MCP, then collaborate live on a shared canvas with your team.

## Start here
- [Excaliwow](https://excaliwow.com/): Real-time Excalidraw workspace with a developer platform — drive diagrams from the CLI, REST API, or an AI agent over MCP.
- [Excaliwow vs Excalidraw](https://excaliwow.com/excalidraw-alternative): How Excaliwow compares to Excalidraw: hosted accounts, persistent diagrams, live multiplayer, and a REST/CLI/MCP developer platform.
- [Excalidraw MCP workspace](https://excaliwow.com/excalidraw-mcp): Connect Claude, Codex, or another MCP client to persistent Excalidraw diagrams that people can refine in the browser and agents can update in place.
- [Editable AI architecture diagrams](https://excaliwow.com/editable-ai-architecture-diagrams): Turn source files into editable AI architecture diagrams, review the canvas by hand, and ask an agent to update the same persistent Excalidraw diagram.
- [Free Excalidraw API workflow](https://excaliwow.com/free-excalidraw-api): Evaluate a hosted Excalidraw REST API workflow that creates, renders, safely updates, and opens the same persistent diagram—with core access kept free for the first 10,000 verified accounts.
- [Editable OAuth sequence diagram](https://excaliwow.com/oauth-sequence-diagram): Build an editable OAuth authorization-code and PKCE sequence from bounded source, review the trust boundary, and update the same Excalidraw canvas.
- [Mermaid vs editable Excalidraw](https://excaliwow.com/mermaid-vs-editable-excalidraw): Compare Mermaid’s text-source-of-truth workflow with a persistent freeform Excalidraw canvas using the same bounded architecture and an honest choose-either guide.
- [Miro alternative for developers](https://excaliwow.com/miro-alternative-for-developers): Compare Miro Free with Excaliwow for repository-to-diagram work, official MCP access, human review, sharing, and free-plan boundaries.
- [Eraser alternative for developers](https://excaliwow.com/eraser-alternative-for-developers): Compare Eraser Free and Excaliwow for diagram-as-code, full MCP workflows, API access, freeform review, and persistent technical diagrams.
- [Excalidraw CLI workflow](https://excaliwow.com/excalidraw-cli): Create, render, update, and hand off a persistent Excalidraw diagram from the terminal with @excaliwow/cli, JSON output, and explicit files.
- [Diagram a repository with AI](https://excaliwow.com/diagram-a-repository-with-ai): Diagram an unfamiliar software repository with an AI coding agent using bounded source, a non-invention prompt, browser review, and same-canvas follow-up.
- [Kubernetes deployment diagram](https://excaliwow.com/kubernetes-deployment-diagram): Turn Kubernetes Deployment, Service, and Ingress YAML into an editable rollout review covering probes, ready endpoints, traffic, and rollback.
- [Update an Excalidraw diagram with an API](https://excaliwow.com/update-excalidraw-diagram-with-api): Choose additive edit, element patch, or regeneration for an existing Excaliwow diagram and demonstrate best-effort optimistic stale-read refusal.
- [AI diagram review workflow](https://excaliwow.com/ai-diagram-review-workflow): Review AI-generated technical diagrams with a source boundary, critical-path check, meaningful human correction, preserved update, and accountable team handoff.
- [Persistent AI diagrams](https://excaliwow.com/persistent-ai-diagrams): Keep one AI-created Excalidraw diagram id and editor URL across agent creation, browser refinement, team review, same-canvas updates, and a later session.
- [Resources — guides, workflows, and comparisons](https://excaliwow.com/resources): Index of every Excaliwow workflow guide and tool comparison: repository-to-diagram with an AI agent, the MCP / CLI / REST platform, and how Excaliwow compares to Mermaid, Miro, and Eraser.
- [FAQ](https://excaliwow.com/faq): Answers to common questions about Excaliwow — what it is, what it costs, the API/CLI/MCP, sharing, and privacy.
