About Waldo

Waldo is the world’s first no-code automated testing platform for mobile apps. Until now, testing has either been tedious and manual, or brittle and reliant on engineers scripting. We’ve invented an entirely new, proprietary approach that does not rely on any scripting (🤫 but under the hood, we've built an equivalent of Git for UIs so we're able to navigate application changes). With this, we can deliver the power of automation with the ease of no-code. It's an exciting challenge having no one to copy - now it's our job to lead:

"I don't know all the details of how Waldo does it, so I hope they can share more about it some day and bring the community forward" Android Tech Lead @Square, reference:

We are a tech and product-led company that gives its engineers ownership and autonomy in everything they do. We thrive off of a good challenge, always seeing it as an opportunity to innovate, learn, and grow as individuals, a team, and a company.

We are backed by First Round Capital (Uber, Square) and Matrix Partners (Apple, Hubspot), and our customers include some of the world's most well-known apps (Lemonade, Plenty of Fish, AllTrails). If you're curious to try the platform, we have a free version that allows you to record tests on your own app in just a few minutes at
