Hi HN — solo developer here. I built this tool ~4 years ago purely to solve my own frustration with CORS and repeated proxy setup. The idea was intentionally boring: just prefix a URL and get control over the request and response. Somehow it grew to serving billions of requests per day, including usage by companies and universities. I’m sharing it here mainly to: - get technical feedback - learn what people would actually use a proxy like this for - understand what I should simplify or remove

I strongly believe that every developer is a teacher and likewise. Every time you are asked to help someone else understand your code, you’ll always be grateful to be able to share your own knowledge with others. Explain Code App is the place you can make this happen! I am eager to hear your thoughts on what I have put together so far. Would love to hear your feedback! Let me know if there are any other features you would like for this site, I’m open for ideas and would love the community feedback. Here is the link: https://www.explaincode.app/
