Show HN: The Quiet Map – Earth's quietest place, measured by seismometers Hey HN,<p>This started as a personal curiosity and Claude helped me build it out.<p>The Quiet Map reads 98 broadband seismometers from around the world every hour. Ground vibration in the 4–14 Hz band is usually done by human activity - traffic, trains, footsteps etc. Each station is compared against its own history at the same hour of day, and the map names the place currently furthest below its own normal: the quietest place on Earth right now.<p>Hope you enjoy it and would love your feedback!

Show HN: OpenBenchmarks – Helping agents discover and pick the right SaaS APIs I&#x27;m Fenil, co-founder&#x2F;CEO of OpenFunnel (YC F24), building this with my co-founder&#x2F;CTO Aditya. We&#x27;re launching OpenBenchmarks (<a href="https:&#x2F;&#x2F;openbenchmarks.com" rel="nofollow">https:&#x2F;&#x2F;openbenchmarks.com</a>), open-source, reproducible benchmarks for SaaS APIs, starting with the category we know best: GTM APIs.<p>## Why we built this<p>More and more B2B software evaluation will&#x2F;already runs through reasoning models inside agentic workflows rather than through people. And buyers increasingly pick vendors that are API-first and ship MCPs, so they can wire them into internal workflows. Strong reasoning models are skeptical of marketing. When a genuinely neutral benchmark is available, they discount SEO and self-published benchmarks, and they lose trust the moment something looks like a marketing claim.<p>The thing that survives that skepticism is an independent build-first benchmark the agent can reproduce itself and trust.<p>Reproducible by default: every cell ships the literal HTTP request&#x2F;response plus the judge prompt&#x2F;response<p>All benchmarks live at <a href="https:&#x2F;&#x2F;github.com&#x2F;openbenchmarks-labs" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;openbenchmarks-labs</a>. We start with GTM APIs, with more on the way.<p>## On Benching ourselves<p>We benched our own product (OpenFunnel) as a vendor in the lookalikes benchmark, on purpose.<p>We increasingly saw buyers asking for benchmarks on sales calls and were also curious to see if agents also made decisions the same way.<p>We wanted to see whether an agent could run the whole loop end to end: discover the benchmark while researching a user&#x27;s query, weigh it as the deciding factor in picking a winner for that user&#x27;s category, then sign up and auth through to the chosen vendor to complete the task. That last stretch needs live vendors with agent-auth wired up: us and a few others.<p>We came out #1 on the current seed (89% vs 74%). Because it&#x27;s open, we don&#x27;t win everything: depending on seed and metric (precision@10&#x2F;@50&#x2F;@100), we win some and lose others.<p>## Dogfooding<p>We dogfooded it and ran 200 incognito simulated buyer flows through Claude Code with live web search, from query to discovery to sign-up, and watched which sources the model fetched and which ones made it into the final decision. The benchmark got opened in a large majority of runs, across the range of queries an actual buyer would ask in Claude Code, from building a lookalikes workflow to picking a lookalike API provider. And when it was opened, it usually drove the final call, over self-published GEO pages and vendor benchmarks with years of domain authority.<p>We&#x27;ve studied the effect and potential ROI of being benched, we&#x27;re taking OpenFunnel off the benchmark.<p>## What&#x27;s next<p>More GTM benchmarks, then beyond: devtools and infrastructure.<p>We&#x27;re are also working with traditional SaaS companies thinking about going API-first and opening up to a new class of customer: agents<p>Try it, or hand it to your agent: <a href="https:&#x2F;&#x2F;openbenchmarks.com" rel="nofollow">https:&#x2F;&#x2F;openbenchmarks.com</a>

Show HN: Ant – A JavaScript runtime and ecosystem Hello HN!<p>I&#x27;m the author of Ant, a JavaScript ecosystem built around a runtime with its own JavaScript engine. Ant also includes a package manager, the ants.land package registry, a platform for deploying and hosting applications, and Ant Desktop for building native desktop apps with web technologies, similar to Electron.<p>The goal is for these pieces to work as one coherent platform while remaining compatible with the wider JavaScript ecosystem. It&#x27;s still early, and I&#x27;d appreciate any feedback on the overall direction or what you&#x27;d like to see from an e2e alternative to the existing JavaScript stacks.<p>P.S. I’ve shared Ant here before as a runtime; since then, it has grown into the broader ecosystem you see today.

Show HN: Orbit – AR satellite tracker, watch 15k+ objects Hey HN! I made Orbit, an iOS app that allows you to see the satellites, planets, and constellations above you in AR, on a 2D map, and on a 3D globe. The app includes more than 15,000 objects tracked by CelesTrack, together with their pass predictions, descriptions, and detailed orbital data. A searchable catalog of all objects is also available, as well as a built-in chatbot designed to answer any space-related questions you might have.<p>This is my first published iOS app, so any feedback is greatly appreciated!

[Other] Show HN: Clx – Compile Lua to Native Executables Through C++20 Hi HN,<p>clx is an ahead-of-time compiler for standard Lua that generates C++20 and produces standalone native executables through GCC, Clang or MSVC.<p>The project started as an experiment to see whether modern C++ could be used as a portable compiler backend instead of LLVM or direct machine code generation. The generated code is then compiled and optimized by the host toolchain.<p>The latest release replaces the previous NaN-tagged value representation with a new shadow-types implementation, adds full int64 support, improves native arithmetic code generation and adds ARM64 macOS coroutine support.<p>Performance is typically much faster than the Lua interpreter and can outperform LuaJIT on some computation-heavy workloads while remaining fully ahead-of-time compiled.<p>The repository also contains graphical examples written in Lua, including a Pong game and a Mandelbrot explorer using a Sokol binary module (using the clx C++ API)<p>I&#x27;d be very interested in feedback on clx :)

Show HN: Hidetext.sh – encrypted pastebin where the server never sees the key Hi HN! I built hidetext.sh — a way to share text, code, and files through links the server can&#x27;t read.<p>How it works: your browser generates a random key and encrypts everything locally (NaCl secretbox, XSalsa20-Poly1305). Only ciphertext is uploaded. The key goes into the URL fragment — the part after # — which browsers never send to servers. The link carries the key, my server stores the locked box, and the two only meet in a browser.<p>A design detail I&#x27;m fairly happy with: burn-after-read doesn&#x27;t destroy the paste on the first HTTP request. The naive version means a Slack or iMessage link preview &quot;reads&quot; your paste before the recipient ever opens it. Instead, the reader&#x27;s tab sends a heartbeat, and the paste is deleted only once nobody is watching it anymore.<p>Being upfront about the limits (full page at hidetext.sh&#x2F;how-it-works): you&#x27;re trusting the JavaScript I serve — inherent to any browser-based E2E tool; filenames are stored in plaintext (contents aren&#x27;t); and anyone holding the link can read the content, because the link is the key. No accounts, no cookies, no analytics, IPs aren&#x27;t stored.<p>Stack: Next.js static on Cloudflare Pages, Pages Functions, D1 for metadata, R2 for encrypted blobs.<p>It&#x27;s free. I&#x27;d love feedback — especially on the threat model and anything you&#x27;d expect from a tool like this that&#x27;s missing.
