We have worked with thousands of amazing people

Seriously impressed by Zencoder. Spent 2 hours banging my head against the wall, trying to refactor something with other agents, and Zencoder did it in 10 mins just now!

After testing various free CodeGen tools with a 1K LOC Java class, I found most generated poor documentation, incorrect bug suggestions, and non-compiling unit tests. Revisiting the challenge with Zencoder, I was impressed—it outperformed others in code generation and significantly improved unit test creation, even for complex classes.

I’ve been testing the unit test generator (Python/PyCharm) and it’s a game-changer! Zencoder is a huge productivity booster for our team, with 80% of the code just there, ready to go.

Using Zencoder, it became possible to create simple Restful API scripts, and my productivity skyrocketed. All you need to do is tell Zencoder which API you want to use in the chat, and what the input and output should be. Zencoder will then find the necessary libraries and create the script for you. It's the best experience.
