Open-source alternative
Replace Lucidchart with draw.io / Excalidraw
The best open-source alternative to Lucidchart is diagrams.net or Excalidraw, self-hosted on Railway. Diagrams you host. diagrams.net (draw.io) is Apache-2.0; Excalidraw is MIT — Lucidchart without the seat.
Estimated save $1,200 a year.

FAQ
- Is it free?
- The draw.io / Excalidraw licenses are open source or fair-code. You still pay hosting (Railway or any VPS) and any APIs the stack calls. There is no Lucidchart seat or task bill on this path.
- Can I migrate from Lucidchart?
- Yes. Start with the workflows or data you actually use, then cut over. The draw.io / Excalidraw stack page has the agent prompt and the cost table; most teams rebuild the slice that matters and leave old Lucidchart links until they expire.
- How do I deploy it?
- Open the draw.io / Excalidraw stack, copy the agent prompt, and deploy on Railway (one service, PORT, and a volume when the app needs disk). Placeholder: diagrams.net (jgraph/docker-drawio) plus a volume if you persist .drawio files, or reuse Excalidraw on /stacks/excalidraw-whiteboard. No one-click template in this repo yet — Start on Railway.
- What does this replace?
- Lucidchart. The published small-team estimate on this stack is $1,200 a year.
