Questions & Answers

As answered by people managing CodeCrafters and DemoBot.dev.

What makes your product unique?

DemoBot.dev's answer:

Most agents checking your PRs are reviewing code or running tests. DemoBot isn't for verifying how something gets built, its for the human that requested the work to verify what got built.

What's the story behind your product?

DemoBot.dev's answer:

Writing code has completely changed, the idea of reviewing every line of code is dying. Automation tests and AI code review is going to cover the quality of code itself and prevent regressions. What stakeholders will really care about is "Did this code satisfy requirements". We have encountered this personally in our own development work, results matter much more than how we got to those results.

How would you describe the primary audience of your product?

DemoBot.dev's answer:

Product Managers, Developers, Marketers - anyone who wants to see UI changes sooner.

Why should a person choose your product over its competitors?

DemoBot.dev's answer:

DemoBot is quick and easy to setup and "just works". For most apps just install the Github App. For Apps requiring some additional config, just drop our prompt into your coding agent and it'll take care of the rest.

Which are the primary technologies used for building your product?

DemoBot.dev's answer:

We used Claude and our own proprietary AI Agent platform as our primary assistants. It's implemented in TypeScript and deployed on AWS with MongoDB for persistence. We leverage Lambda MicroVMs for running customer code, ensure secure isolation for both our security and yours.
