Can we build better DX with a change in perspective?

Your computer can test better than you (and that's a good thing)

We deploy to production on Fridays. Can you? It sounds way less crazy when we tell you how autonomous testing rearranges the canonical DevOps cycle that underpins most of software delivery today.

An ounce of prevention is worth a pound of cure

Engineering teams spend too much time and money managing bugs that are found in production. What if there was a better way?

Solving Zelda with the Antithesis SDK

The Legend of Zelda features a non-linear open world, which makes it exceptionally difficult for artificial agents to master. But with judicious use of the Antithesis SDK, we not only beat it but find lots of bugs along the way.
