Excalidraw Review for Solutions Engineers

Excalidraw Is the SE's Napkin Sketch Tool

Excalidraw produces diagrams that look hand-drawn. Boxes have slightly irregular edges. Lines have a natural wobble. Text looks handwritten. This aesthetic is intentional, and it serves an important purpose in pre-sales conversations: hand-drawn diagrams feel collaborative and in-progress, not final and prescriptive. When an SE sketches an architecture in Excalidraw during a call, the prospect perceives it as "we're figuring this out together" rather than "here's a pre-built solution we'll force on you."

The tool is open source and free. You open excalidraw.com in a browser, start drawing, and share a link for real-time collaboration. No account required. No installation. No pricing conversation with procurement. This zero-friction access makes Excalidraw the fastest path from "let me sketch this out" to a shared diagram. For SEs who frequently draw architectures during calls, the speed is hard to beat.

Excalidraw's component library is growing but smaller than Lucidchart's. You will not find pre-built AWS or Azure icon sets at the same level. But that is not the point. Excalidraw is for quick, conceptual diagrams that explain an idea, not for production-ready architecture documentation. Use Excalidraw during the call to sketch the concept. Use Lucidchart after the call to formalize it into a polished diagram if needed.

With 12 mentions in SE job postings and a 4.8 rating (the highest in any tool category we track), Excalidraw has passionate users but limited market penetration. The tool's popularity is driven by word-of-mouth among technical professionals who appreciate its simplicity and hand-drawn aesthetic. For SEs comfortable with a minimalist tool, Excalidraw is a delightful addition to the toolkit. For SEs who need structured, formal diagrams, Lucidchart or Miro are better primary tools.

How SEs Use Excalidraw

• Live call sketching. Open Excalidraw during a call and sketch an architecture concept in real time while the prospect watches and contributes.
• Quick conceptual diagrams. When you need to explain an integration approach or data flow in 2 minutes, Excalidraw is faster than any other tool.
• Internal team communication. Sketch ideas for product feedback, deal strategies, or architecture approaches to share with colleagues.
• Whiteboarding practice. SEs preparing for whiteboarding interviews or demo presentations can practice in Excalidraw's low-pressure environment.
