What it does
Push a branch and PreviewDrop builds a live HTTPS preview URL automatically. Open a PR and the link drops in the comment. Django, Rails, Laravel, FastAPI, Spring Boot, Node, Go — if it runs in Docker, PreviewDrop previews it. No YAML, no staging server to maintain. Flat pricing per workspace, no per-seat fees. Free tier from day one, no credit card required. MCP support: trigger preview deployments from Cursor, Claude Dev, or any MCP-compatible editor.
Live HTTPS preview URLs for every Git branch — Django, Rails, Laravel, FastAPI, Next.js, Nuxt and beyond. Auto-detects your framework (no Dockerfile required — bring one if you want). GitHub and GitLab. PR comments, logs, password protection in 60s.
A real container, a real HTTPS address, a real PR comment — for Django, Rails, Laravel, Go, .NET, Rust and anything else that builds. We detect the framework, or use your Dockerfile. No Kubernetes, no YAML, no per-seat bill. No signup, no credit card, self-destructs in 10 minutes. No repo handy? Try Express , FastAPI , Next.js . Already convinced? Sign in with GitHub — free, no credit card. Stages in order, not to scale — no per-stage timing is claimed here. What is fixed: a real container per branch, its own HTTPS certificate, and an expiry you don't have to remember. If it runs in a container, PreviewDrop previews it. Detected automatically, or driven by the Dockerfile you already have.…from previewdrop.dev

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…
