Overview
Otto Engineer, also known as Otto, is an AI-based software that acts as an autonomous coding assistant. Catered for developers, it runs directly in the browser and is designed to simplify the process of software engineering.
One of its key features includes the ability to execute code and conduct testing, iterating through the code until a functioning version is achieved. It can handle errors through continuous iterations, striving for functional code.
Another feature, aided by Web Containers technology, allows it to execute code safely in isolation, with the use of a virtual, in-memory file system. This means that Otto can operate securely without risking system vulnerabilities.
The software also requires no setup, indicating an ease-of-use for users who just need to instigate a new chat and let Otto work. It can run commands and modify code in the embedded terminal and editor, which users can observe.
Additionally, Otto is designed to operate in a genuine environment, able to install and use npm packages, amend its TS config, and write its own tests.
Users can use it to create complicated utility types, eliminating the issue of 'hallucinated' code that doesn't function properly.

Johnson🙏 113 karmaJul 16, 2025@OnSpace.AI - No Code App BuilderWould rate 4.9 if possible, but rounding up to 5 stars because this app truly excels compared to other AI coding tools. Why 5 Stars: Best-in-class AI coding assistance Huge improvements over competitors Actually works for real development Real Impact: I successfully built and published an actual app using this tool - that's game-changing for non-developers like me. Bottom Line: Yes, there's room for improvement, but this is already the top AI coding app available. The fact that ordinary people can create real apps with it says everything. Perfect for anyone wanting to turn ideas into actual apps! -
