WebCanvas

Overview

WebCanvas is an online evaluation framework for web agents that explicitly addresses the fact that the web keeps changing. It couples online tasks with intermediate evaluation states and maintenance tooling so the benchmark can remain alive rather than fossilized.

Why it matters

It matters because interface drift is not a nuisance around the edges of web-agent evaluation; it is the actual medium. WebCanvas treats that as a first-class design problem.

Distinctive trait

Its distinctive trait is benchmark maintenance under live web change, with lightweight annotation and testing pipelines rather than one frozen dataset.
