tldraw has officially released SDK 4.0, the fourth major version of its infinite canvas tool. This new version introduces several changes, including the addition of several new Starter Kits, licensing adjustments, and significant accessibility upgrades. Developers should be aware of some breaking changes. This version adds Starter Kits, including the Cursor-for-tldraw agent starter, which supports integrating AI interactions, branch chat, multi-person collaboration, and workflows into the canvas. All Starter Kits are licensed under the MIT license, making it easy to quickly build applications. While the development environment remains free to use, the production environment requires a valid license key and offers a 100-day free trial.
In terms of accessibility, tldraw SDK 4.0 meets WCAG 2.2 AA standards, adding a high-contrast mode, improving keyboard operation and menu scrollability, and enhancing support for aria-labels and shortcut keys. These improvements make the canvas easier to use in more user scenarios.
