Build for Yourself, Not by Yourself

Pre-Built Models

Jumpstart projects with our library of industry-proven algorithms (e.g., NVH fingerprinting, acoustic material QA).

AI

Custom AI Model Training

Train custom AI models using TensorFlow/PyTorch to spot anomalies in TWS earbuds, EV motors, or industrial bearings—no PhD needed.

App Marketplace

Access specialized industry solutions — from automotive NVH to concert hall acoustics optimization — through pre-configured workflows that deploy in one click, streamlining development from prototype validation to full-scale production.

Plugin Marketplace

Engineer beyond limits — OpenTest's modular plugin architecture empowers you to extend system capabilities by building custom data acquisition logic, AI-powered analysis (e.g., noise anomaly detection), and domain-specific dashboards. Seamless SDK integration with LabVIEW, Matlab, and Python ecosystems accelerates development while maintaining enterprise-grade security. 

Build Faster, Ship Sooner

No-Code Workflows

Drag-and-drop interface to design test sequences (e.g., signal generation → data capture → AI analysis → report generation).

Code-Friendly

Call Python, MATLAB, LabVIEW scripts or REST APIs for custom logic.

Secure, Scalable, Yours

Hybrid Cloud Options

Choose local, private, or SaaS deployment. Comply with data regulations while enabling global team collaboration.

Flexible Subscription Plans

Mix and match modules and computing resources with annual/monthly subscriptions or perpetual licenses. Scale seamlessly as your business grows-from startups to enterprises.

Support for TEDS

Plug-and-play
