tldraw_data:Excalidraw vs tldraw: Frequently Asked Questions
What is the primary difference between Excalidraw and tldraw?
Excalidraw is a self-hosted open-source software (MIT licensed) focused on Virtual collaborative whiteboard for sketching hand-drawn diagrams. In contrast, tldraw is a self-hosted open-source solution (Fair-Code licensed) focused on High-performance infinite canvas and collaborative whiteboarding SDK.
How much money can a 25-person team save by choosing Excalidraw?
Commercial per-seat SaaS tools typically charge $10–$40/user/month ($3,000–$12,000/year for 25 seats). Self-hosting open-source software on a private VPS (typically $10–$25/month on Hetzner or DigitalOcean) reduces recurring software expenses by up to 95%.
What are the production server hardware requirements for self-hosting?
For Excalidraw, recommended baseline memory is 1 GB - 2 GB RAM (Hetzner CX22 / $4/mo). For tldraw, recommended memory is 1 GB - 2 GB RAM (Hetzner CX22 / $4/mo). Both can be provisioned using modern Docker Compose configurations.
Is data export and migration supported between Excalidraw and tldraw?
Yes. Open-source solutions prioritize data portability with standard SQL database dumps, JSON/CSV exports, or native markdown files, ensuring zero vendor lock-in.
