tldraw

A collaborative whiteboard and the SDK behind it, at 50,000 stars, with a 21 KB llms.txt covering every feature

Tier A · StrongToolComponent LibraryApptldraw.com

tldraw is two things under one name. tldraw.com is a free collaborative whiteboard that opens instantly with no account. tldraw.dev is the SDK, and that is the half this corpus cares about. The SDK builds a canvas into your own product. Its documented feature list is long and specific: accessibility, actions, animation, assets, attribution, bindings, a camera system, click detection, clipboard and collaboration, and it continues past those. A canvas is one of the hardest interfaces to build well, and this one is solved and shipping. The repository carries 50,033 stars and was pushed on 2026-08-28. Read the licence before you ship. It is not open source in the usual sense: the software is copyrighted by tldraw Inc., using it means accepting their terms, and alternative commercial and non-commercial licences are sold separately. GitHub reports the licence as unrecognised for that reason. tldraw.dev publishes a 21 KB llms.txt indexing every SDK feature page.

For an agent

Separate the two domains. tldraw.com is the app and tldraw.dev is the SDK, and only the second one matters when you are building. Read https://tldraw.dev/llms.txt first. It is 21 KB and indexes every SDK feature page by name, so you reach the right document without crawling. Check the licence before you ship commercially. The repository is not MIT: the code is copyrighted by tldraw Inc., the licence binds you by use, and separate commercial terms are sold. GitHub cannot classify it. Reach for it whenever a brief needs a canvas. Camera, bindings, click detection and collaboration are the parts that sink a hand-built canvas, and all four are documented features here.

Why it is here. A collaborative canvas is one of the most expensive interfaces to build from nothing. This is the one production-grade answer in the corpus, and its documentation is written for a model to read.
