About

Diffblue, a spin-out from the University of Oxford, was founded in 2016 by Daniel Kroening and Peter Schrammel. Mathew Lodge assumed the role of CEO in July 2019. The company's flagship product, Diffblue Cover, is an AI-powered tool designed to automatically generate comprehensive unit tests for Java code. This innovative solution significantly streamlines the unit testing process for software developers, saving considerable time and effort compared to manual testing, thereby enabling faster and continuous delivery of high-quality software. While similar to GitHub Copilot in its use of AI for code generation, Diffblue Cover distinguishes itself by autonomously writing code rather than providing suggestions for human review. The product is available with a free version and free trial, operating on a subscription model, and has received a strong rating of 4.1 based on 32 reviews.
