Every tool in this app started as something I was already using across multiple websites and applications. Whether it was Path Query, quick code generators for prototyping, or simply formatting and structuring data as JSON or XML, I found myself constantly switching between different tools. So added YAML and Markdown.
Another recurring problem was finding data I had already worked with a day or a week earlier. It could be a JSON structure, an API request, or a test payload that I needed again. Too often, it was lost because I had validated it on a website or used a tool that didn't save my work.
