Write end-to-end test automation in plain English, no code required
Build and maintain end-to-end tests using free-flowing plain English. testRigor interprets your instructions exactly as written and executes them, with no coding required.
Tests adapt to UI changes automatically, so you spend far less time fixing broken selectors and scripts. Customers report near-zero maintenance versus Selenium and Appium.
Cover web, iOS and Android mobile, native Windows desktop, API, email, SMS, phone calls, 2FA, and mainframe testing from a single tool.
Generate tests directly in testRigor or through Claude Code using MCP and Skills, and import existing manual test cases to get started quickly.

Real-time vision AI models and a full platform to train, annotate, and deploy them
One model family covering detection, instance segmentation, pose estimation, oriented boxes, classification, and tracking, tuned for real-time inference on GPU, CPU, and edge devices.
Label data with SAM-assisted annotation, train on cloud GPUs with AutoTrain, and deploy to managed regions that scale to zero when idle.
Ship trained models to ONNX, TensorRT, CoreML, TFLite, and many other formats for cloud servers, mobile devices, and embedded hardware.
Adopt the open-source AGPL-3.0 release, or purchase an enterprise license to embed YOLO in closed-source products without copyleft obligations.
