Locator-Free Testing
Stop wrestling with flaky XPaths and CSS selectors. Describe what you want to interact with, and AI identifies the right element using full DOM and semantic context.
Start for free • No credit card required
Plain English execution
Write tests without inspecting elements or copying selectors from the DOM.
Accessibility-first targeting
Semantic HTML and ARIA roles improve both reliability and developer ergonomics.
Debuggable outcomes
Use traces and snapshots to understand what the agent saw when a step passed or failed.
Traditional automation relies on hardcoded selectors that break when the UI changes. Mechasm analyzes rendered structure, accessibility signals, and surrounding context so tests stay resilient without constant selector maintenance.
How the locator-free approach works
Instead of locking onto one CSS attribute or XPath, the agent evaluates the page holistically before acting.
Rendered DOM analysis
The system reasons over visible structure instead of relying on one brittle selector string.
Accessibility tree signals
Roles, names, and semantic structure help stabilize targeting across UI refactors.
Complex structure support
Shadow DOM and iFrame-heavy interfaces can still be traversed to find the intended element.
Why this improves reliability
The goal is not novelty. It is to reduce fragile maintenance loops in modern web apps.
Fewer brittle updates
UI refactors are less likely to force test rewrites because the agent reasons over semantics and context.
Better debugging
Trace and snapshot tooling helps you inspect exactly what the agent evaluated at runtime.
Works with self-healing
Locator-free execution and self-healing complement each other to reduce the maintenance burden of UI automation.
