LinkPeek

What it does

Most OG preview tools only work on live URLs. LinkPeek works on localhost too — no ngrok, no deploys. Paste any URL and instantly see how it looks on WhatsApp, Twitter, LinkedIn, Slack, Discord, and Facebook. Built for developers, designers, and marketers who are tired of deploying just to check a meta tag.

  Metacheck – preview how any link appears on social media and chat apps2025 · metacheck.appstate.co · ▲165

  Hey HN, I’ve been an indie hacker for a while, but I haven’t had much success with my past projects. Recently, I came across Marc Lou’s advice about building free tools just for fun, so I decided to give it a shot. I built Metacheck, a simple tool that lets you preview how any link will appear on Twitter/X, LinkedIn, Whatsapp, Telegram, and other platforms. No API keys, no setup—just paste a link and see the preview. Why I built this I often ran into issues where social platforms displayed broken or unexpected link previews. Debugging Open Graph meta tags was annoying, so I made a tool…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  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…
