What each one is
Excalidraw
Excalidraw is an open-source whiteboard where you draw diagrams, wireframes and sketches in a deliberately hand-drawn style. The hosted app at excalidraw.com adds real-time collaboration, end-to-end encryption and autosave to the browser. The same editor is also published as an npm package that developers can embed in their own apps.
fireworks-tech-graph
fireworks-tech-graph is an Agent Skill that works in Codex and Claude Code. You describe a system in English or Chinese, and it generates SVG diagrams, high-resolution PNG exports, short GIF animations of diagram flows, and offline interactive HTML diagrams. The README says it supports UML diagram types and AI/agent workflow patterns, so it is aimed at people who need architecture or flow diagrams without drawing them by hand.
Best for
Excalidraw
- Teams sketching diagrams or wireframes together in a shared canvas
- People who want a casual, informal look for explanatory drawings
- Developers who want to embed a whiteboard editor in their own React app
- Users who care about end-to-end encryption for shared drawings
- Anyone who wants drawings saved in an open .excalidraw JSON format
fireworks-tech-graph
- Developers who want architecture or flow diagrams from a text description inside Claude Code or Codex
- Engineers preparing C4, cloud deployment, or reliability review diagrams
- People documenting AI agent or memory architectures
- Teams that want consistent diagram styles across documentation
Strengths
Excalidraw
- Free and open source under the MIT license
- Simple, approachable drawing tools with a distinctive hand-drawn look
- Open .excalidraw JSON format and export to PNG, SVG and clipboard
fireworks-tech-graph
- Works with both Codex and Claude Code as a single Skill, according to the README
- Offers 12 visual styles and 14 UML diagram types as described in the README
- Released under the MIT license, which permits free use and modification
Not ideal for
Excalidraw
- Users who need precise, pixel-perfect vector design; the hand-drawn style is the default look and the README does not describe precision tools
- People wanting to self-host the collaboration service; the README only links to the hosted app for real-time collaboration and does not describe a self-hosting setup
- Non-developers who only want the hosted app and have no need for the code; the npm and development sections are aimed at developers
fireworks-tech-graph
- Anyone who needs a pure drag-and-drop diagram editor, since the README describes generating diagrams from natural language rather than an interactive editing UI
- Users who do not use Claude Code or Codex, since the README frames it as an Agent Skill for those tools
- People who need guaranteed pixel-perfect layout without reviewing output, since the README notes measurement limits for text fit
Trade-offs
Excalidraw
- Collaboration and encryption are features of the hosted app; the README does not detail how to run them yourself
- Development setup is covered only by a linked guide, so the README alone gives limited build detail
- No downloadable binaries in the latest release; use the web app or the npm package
fireworks-tech-graph
- The README is truncated and does not fully document setup, so some details are unclear
- Text-fit and layout quality depend on the generator, and the README notes measurement limits
- Documentation is partly in Chinese and English with some sections that assume familiarity with Agent Skills
