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.

Hi HN, Gabriel, Co-Founder at Permit.io. We're releasing Permit MCP Gateway today, an authorization proxy for MCP servers. TL;DR - we built an MCP Gateway that developers love and CISOs trust. Watch more[0] Now, after your little hate on using fancy copy on HN, to the real thing: MCP is in a strange place. Developers are debating whether it's overcomplicated compared to CLIs or skills files.

uBlock Origin is more than an ad-blocker, it's a general purpose content filter that can be leveraged to hide low-quality content from pages you browse. While the main filter lists can remove mailing list popups and obvious nags, the definition of low-quality content is personal, so one size cannot fit all. I used to have an ad-hoc script to render and publish a personal uBlock Origin filter list, added to all my browsers. The goal of this project is to enable more people to build such a list custom list to filter out low-quality content and nags. Chose from a list of community-maintained…

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