ACCELQ is a codeless testing platform built around agentic AI, designed for teams that need to automate testing across web, mobile, API, desktop, and packaged applications. It supports enterprise platforms including SAP, Salesforce, Oracle, Workday, MS Dynamics, nCino, Coupa, and ServiceNow, so teams can manage different testing needs in one place instead of relying on separate tools. Autopilot sits at the center of the platform. It brings together multiple AI agents that can understand an application, create tests, run them, investigate failures, repair affected tests, and rerun them when needed. The goal is to reduce the amount of manual direction involved in day-to-day automation and move beyond the typical AI-assisted model, where a tester still has to define every flow and step in to apply fixes. Test logic can be written in plain English, which makes automation easier for teams that do not want to depend on scripting for every scenario. ACCELQ also uses self-healing locators and Anchor Elements to help tests stay stable when the application changes. Over time, this can reduce the effort spent fixing broken tests and maintaining large automation suites. The platform is built for teams that want broader automation coverage without adding more code or maintenance overhead. It can support continuous testing across different application layers while giving both technical and non-technical users a way to contribute to automation and work from the same testing process. ACCELQ was named a Leader in The Forrester Wave™: Autonomous Testing Platforms, Q4 2025. It received the highest Current Offering score and was the only vendor recognized as a Customer Favorite in that evaluation. ACCELQ also won the 2025 AI Breakthrough Award. Customers have reported 7.5x faster automation development, 72% lower test maintenance effort, and 53% lower costs compared with scripted testing approaches.
