Hi HN, I'm one of the founders of s2.dev. RePlaya (https://github.com/s2-streamstore/replaya) is a self-hosted browser session replay tool using rrweb (https://github.com/rrweb-io/rrweb). It occurred to me that a durable stream per session would be a much neater architectural foundation for much of what you'd want from such a tool. As a unique feature, it also made live tailing straightforward because the player can read from the same stream the recorder is appending to. The alternative architecture is likely an ingest firehose which is then indexed,…

Hey HN! We’re open-sourcing highlight.io (https://github.com/highlight/highlight), a session replay and error monitoring tool. Highlight.io gives you a high-precision video-like replay of what users are doing when an error or exception occurs in your web app, along with a full-fledged error monitoring experience (similar to bugsnag, rollbar, etc..). The main value prop of highlight.io is that we help you understand the full context surrounding an error and allow you to drill down to the code path that a user invoked (i.e user clicked button X, sent network request Y, and…

http://instacss.com (in case DNS update hasn't propagated: http://morning-warrior-3377.herokuapp.com/) Last night I was annoyed at how slow (and web 1.0-ish) most CSS reference sites seem to be, so I created this. It's basically a scrape of the CSS reference on w3schools, but with client side searching. Feedback is most welcome! some of the tech involved: node, requirejs, backbone, mongodb the code: http://github.com/rgarcia/instacss

Hey all! I've been using this stack personally for a while now and decided to automate it a bit by turning it into a template I can reuse. Hope others might find it helpful!

Hello HN! Parth, and Shardul here. We have been building unlogged.io for the last 21 months. We started as a time travel debugger and pivoted to record and replay with assertions, mocking, and code coverage. You can save the replays in the form of a JSON and commit them to your git. Both Parth and I come from an e-commerce/payments background where production bugs meant heavy financial losses. Big billion days/Black Friday sales meant months of code freezes with low productivity. Before committing the code, we wanted to replay production traffic and know the breaking changes right…

Hi HN, Rohan and Michael here from Decipher (https://getdecipher.com/). We’re excited to introduce AI-generated session summaries and open source the pipeline. It processes raw rrweb events to produce plain English summaries of what happened leading up to and around an error. You can find the code here: https://github.com/decipherai/session-replay-analyzer We created Decipher because we were frustrated with noisy alerts, time-consuming error triaging, and customer churn due to bugs and session replay analysis is a powerful step forward. Here’s an…

I built Morph, an experimental fullstack HTML-first library for Deno, Node, and Bun. Everything returns HTML, not JSON. No React, no Vite — just plain HTML with server-side rendering. No build steps, no preprocessors, no complex configs — everything runs from a single file. Perfect for Telegram Web Apps, internal tools, simple admin panels, dashboards, or anywhere a full-blown SPA feels like overkill. Important: I built this entirely for myself — to solve my own problems. I hate complex frontend. I hate writing it. And I don’t want to waste time on it. But maybe it’ll help you too.

GitHub repo: https://github.com/AntiKippi/errorpages Live preview: https://kippi.at/public/errorpages/ I've spend the last few days overengineering HTTP status code error pages. It started with me wanting an aesthetic, glitchy 404 page with a bit of "cyberpunk" and "hacker" vibes while still being simple and JS free. It ended in this project. wdyt?
