Playwright is a great framework, but it has some major limitations. AI-generated Playwright tests are often unreliable because they guess at selectors and assertions from code context alone, without verifying that the right things were actually clicked or that the test matches your intent. Decipher uses vision plus the DOM to validate that each step truly worked. With Playwright, you also own the infrastructure, which means managing browsers, CI runners, parallelization, environments, and retries yourself, while Decipher runs tests on managed infrastructure. Maintenance is another challenge: Playwright tests are static, so if you rename a field, move a button, or make other UI changes, your CI can break. Decipher continuously updates tests as your product evolves, so there is no flake triage and no babysitting locators. When failures happen, Playwright usually gives you a stack trace and maybe a screenshot, while Decipher explains the reason in plain language, whether the flow changed, there is a real bug, or a dependency failed. And while visual assertions in Playwright are painful or sometimes impossible, such as checking whether dark mode looks right, Decipher can evaluate the UI visually and semantically, not just through DOM nodes.
