At first I thought “$4.5 million for a JavaScript library!” But I agree this focus is really compelling: We are designing it to serve the unique needs of people who make web interactives, namely: - They require an especially close collaboration between highly talented artists and engineers - They routinely involve members of other disciplines like scientists, data storytellers, or educators - Their output requires uncompromising performance, and high graphical fidelity These exceptionally challenging requirements inform the design of Theatre.js. Instead of building a “design tool” or a “dev tool,” we intend for Theatre.js to enable artists and engineers to collaborate on the same thing, fully own their tech stack, and build domain-specific tools on top. Our motion editor is one such example, with more domain-specific tools on the way.
