When building a developer tool, especially in the early stages, it's crucial to show the product and code examples on the website to attract developers.

When critiquing developer tool websites, I look for social proof, such as GitHub repositories and their star ratings, as well as clear calls to action for trying the product immediately.

When designing a landing page, I simplify the process to a one-button interface, focusing on the minimum information needed to encourage users to push the button.

It's important to have a single, clear call to action on a website. If you want users to try the beta, that should be the primary focus, with other options as secondary links.

The platform can show images and websites to gather feedback on landing pages.

We launched Parse quickly during Y Combinator, using a simple landing page to gauge interest, which was crucial for validating our idea before fully developing the product.

Rapid prototyping and user testing are essential; focus on getting a functional prototype out quickly, using tools to create clickable mock-ups or writing throwaway code to test ideas with users, as building a fully functional product before testing can be an expensive mistake.

It's essential for startup websites to immediately convey their core functionality; otherwise, visitors may miss out on valuable tools if the information is too nuanced or buried.

The ability to prompt effectively is crucial, and users should focus on the product description and user experience.
