WebSentry

Instant A–F security grades for any website with monitoring

What it does

WebSentry scans any website and gives an instant A–F security grade across 75+ checks — SSL, headers, CSP, CORS, cookies, DNS, and more. Results in under 30 seconds. What makes it different: - Free forever, no account needed - White-label PDF reports for agencies - Daily monitoring with email alerts on grade drops - Step-by-step fix instructions for every finding - REST API for CI/CD integration Built for developers and agencies who take security seriously.

    I made tool that let's you see everything about any website2024 · v1.web-check.xyz · ▲411

    Yes, it's open source: https://github.com/lissy93/web-check :) Why I'm building this? There are a lot of tools out there for discovering meta and security data relating to a website, IP or server. But currently, there isn't anything that does everything, all in one place and without a paywall/ user sign up. It's still a WIP, and I'm working on a new version, with some more comprehensive checks, so any feedback would be much appreciated :)

    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…
