Thunder Code: AI-Powered Testing for Software Teams

Thunder Code is dedicated to simplifying and improving quality assurance through intelligent automation.

The company’s mission is to make software testing more efficient, accessible, and smart, enhancing product quality while reducing the traditional complexities of QA workflows.

Thunder Code aims to develop tools that provide advanced testing capabilities to development teams around the globe.

Expert personas for different testing roles

Thunder Code’s platform uses AI to provide:

• Self-healing test suites
• Test creation using natural language
• Real-time debugging insights
• Testing cycles up to 90% faster than traditional methods

The platform integrates with existing developer tools and can be scaled for both startups and larger companies.

Instead of traditional automation tools, Thunder Code uses AI agents called “expert personas” that represent different testing roles, such as UI/UX specialist, accessibility expert, or security analyst.

These personas offer insights without needing users to have advanced technical skills.

Tests can be created in plain English, while the AI manages execution and maintenance, including automatically fixing broken or outdated test cases.

“From Paris to Tunis, our team is reshaping one of the most critical — and overlooked — layers of the software lifecycle. With the global QA market projected to hit $512B by 2033, this is a wave we’re not just riding — we’re helping build it,” says the company.
