What it does
tunnel.to gives your local services a public URL through an outbound connection — no firewall changes, no port forwarding, no VPN. Install via Homebrew, run one command, and your localhost is live. Built for AI agent workflows: expose local UIs, webhooks, SSE streams, and WebSocket services instantly. Useful for receiving webhooks during development or demoing local builds. Free tier requires no account. Paid plans add reserved hostnames, higher traffic limits, and custom domains.

Local development with .local domains and HTTPS2023 · localcan.com · ▲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!

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
