   CORSPROXY▲8

   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

   Hey HN! We’re Alan and Richard from Integuru (YC W24). We generate fast, reliable integrations for platforms lacking official APIs.

Since then, we’ve developed a new approach to reverse-engineer platforms’ source code directly. This solution also includes authentication support. Here’s a demo: https://youtu.be/4l2L8fILC2g?si=nbWbDiFrWZIWRPM7. Many AI products need to integrate with web apps, but platforms…

    Local development with .local domains and HTTPSfree tier, from $8/mo▲84

    Hi HN! I'm Jarek, and I've built this tool that allows publishing .local domains on the local network using mDNS. It also has a reverse proxy that handles HTTPS termination and port forwarding. I'm working on adding more features, like an index page with all available domains or allowing proxy redirects, so you could redirect from HTTP to HTTPS. Let me know if you have any questions or feedback!
