AI test automation and self-healing QA for enterprise apps and AI agents
Point the platform at a flow and it writes a production-grade suite covering happy paths, edge cases and failure states without manual scripting.
When the interface changes, ContextQA detects selector drift and repairs broken locators to cut repetitive maintenance.
Run tests in parallel across Chrome, Safari, Edge, Firefox and mobile devices, integrated into your CI/CD workflow.
Trigger suites and inspect failures without leaving Cursor, Claude Code, Codex or another MCP-compatible agent environment.

Battle-test and harden AI agents before they reach production.
Build bespoke test suites that mirror your real workflows so agents are measured against your rules, not generic benchmarks.
Automatically flag fabricated answers, policy breaches and unsafe outputs before an agent goes live.
Catch broken API calls, malformed arguments and failed agent tool usage that would silently break automations.
Run agents through realistic simulated scenarios to surface weaknesses without exposing real customers or data.
