Design quality gate for AI-generated UI: score any URL on 45 deterministic checks, A–F grade.
Free AI visibility check: can AI crawlers read a site, and do ChatGPT, Gemini, Perplexity cite it?
Deterministic release-compatibility preflight for OPC UA NodeSet2 XML.
Captured web interfaces, screenshots, flows and structured evidence for AI coding agents.
Run, debug, and triage tests from your IDE using natural language, no dashboard switching, no manual data transfers. The TestMu AI (formerly LambdaTest) MCP Server is a single remote server exposing four tool suites: HyperExecute — analyze your project, generate YAML configs and test runner commands, then monitor jobs and sessions. Automation — pull a TestID's details plus command, network, and console logs into one chat for instant root-cause analysis. Includes mobile app upload. SmartUI — explain pixel, layout, DOM, and perceptual changes in a visual regression run, with context-aware React/HTML/CSS fixes. Accessibility — audit any public URL or a local React app against WCAG and get ready-to-apply remediation steps. Connects over https://mcp.lambdatest.com/mcp using OAuth 2.1 — no API keys in your config. One-click install in Cursor; works with Claude, GitHub Copilot, Cline, and any MCP client. Tests execute on the TestMu AI cloud: 3,000+ browsers and 10,000+ real devices.
Uxia brings AI user testing, usability testing and UX research into ChatGPT. It helps product managers, UX designers, researchers and developers evaluate websites, interactive prototypes and digital product experiences using AI-simulated users. Explore potential usability problems, investigate friction in user journeys and use findings to guide product and design improvements.
UI Verify is visual regression testing built for coding agents. Connect the MCP server and your agent (Claude Code, Cursor, Codex) pulls a pull request's UI changes into the conversation, views each visual diff, reads the AI judge's verdict of regression vs intended change, and accepts the intended baselines - all over MCP.
Generate synthetic random user data for testing, demos, and development without using real persona.
MCP server for visual regression testing: triage a PR's UI diffs from your coding agent.
Agentic testing: HyperExecute jobs, test failure triage, SmartUI visual diffs, a11y audits
