PerfLens
Web performance audits beyond Lighthouse
What it does
PerfLens goes beyond a one-time Lighthouse score by keeping performance feedback inside the browser while you build and test. It gives developers live Core Web Vitals, resource diagnostics, root cause summaries, per-URL history, AI-ready fix prompts, and launch evidence packs with desktop/mobile audits, screenshots, videos, and JSON reports. The goal is simple: help developers move faster from “this is slow” to “here’s what to fix next.”

Hey HN. We’re Jay and Vadim from Highlight.io (https://highlight.io). We’re building an open source [1] monitoring platform for web applications. Today we’re excited to be sharing a performance tool we’ve been working on, which helps you inspect the latency of code execution from the client to the server. As engineers at past startups, we often had to debug slow queries, poor load times, inconsistent errors, etc... While tools like Jaegar [2] helped us inspect server-side performance, we had no way to tie user events to the traces we were inspecting. In other words, although we had…

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…
