Testerly Avis 3

"Our partnership with Testerly started when our Magento 2 platform reached its technical limits and we needed to scale. Our project required a team with deep architectural expertise to handle both feature development and system stability simultaneously.
They started with a technical audit of our system, found the bottlenecks that were slowing us down, and fixed them. Besides that, Testerly developed new features using Node.js and helped us implement AI. Thanks to the automation they built with n8n and OpenAI, we got rid of a lot of manual data work that used to take us hours.
The results are great: the site now handles 3 times more traffic without crashing. We’ve cut production bugs by 50% and can launch new products twice as fast as before.
What we liked most is that they don’t just wait for instructions—they actually suggest better ways to do things. Any technical issues were solved quickly during our sync calls, and they always hit the deadlines. It's a solid team that is equally good at both development and automated testing. Highly recommended if you need to scale a complex project."

We teamed up with Testerly on a large retail project to fix a fragmented ecosystem of Shopify, WooCommerce, and OpenCart stores. We needed a partner to handle the automation and backend stability, and they did an incredible job. They built smart workflows using n8n to sync orders and inventory in real-time, which cut manual work by 70% and allowed the business to scale much faster.
Testerly also integrated OpenAI to handle over half of the routine customer inquiries and help with stock forecasting. To make the whole system ""unbreakable,"" they moved everything to Docker and set up an automated testing framework within AWS/Azure. This ""self-healing"" setup means the system automatically checks for bugs during updates, allowing us to release new features twice as fast with 100% data accuracy.

Working with them was seamless. They jumped right into our Slack and Jira, felt like part of our own team, and hit every deadline. They don’t just execute tasks; they suggest smart ways to use AI and automation. For anyone needing help with n8n, Docker, or AI reliability: Testerly is excellent. Highly recommended!

We’ve been collaborating with Testerly on a B2B fintech project for one of our clients, and they’ve been a fantastic partner to work with. They took full responsibility for the quality control, successfully replacing slow manual testing with a smart, automated system.

The team is highly technical and knows their tools inside out. They used Playwright and Postman to secure all banking integrations and conducted JMeter stress tests to ensure the platform could handle 5,000+ users without any issues. We also loved their use of n8n to automate feedback between QA and developers—it made our lives so much easier.

Thanks to their expertise, the project launched with zero critical issues, and we managed to cut manual testing time by 40%. Testerly is a pro team that stays flexible, meets every deadline, and really cares about the result. If you need a solid QA partner for a high-stakes project, I can’t recommend them enough!
