24 alternatives to RePlaya – self-hosted browser session replay with live tailing

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,…

    Been having a lot of fun reading an SC2Replay collection through nom parsers, serializing into Arrow files so that pola.rs can read them and perform data analysis with jupyter lab, plotly or interact with SQL operations, etc. Looking for feedback and ideas on what to progress on. For example, "through history, are my timings getting better?". etc. Also would love to have ideas on what libraries to use to perform forecasting.

    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…

    Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…

    Hi HN, Mike and Warren here! We've been building HyperDX (hyperdx.io). HyperDX allows you to easily search and correlate logs, traces, metrics (alpha), and session replays all in one place. For example, if a user reports a bug “this button doesn't work," an engineer can play back what the user was doing in their browser and trace API calls back to the backend logs for that specific request, all from a single view. Github Repo: https://github.com/hyperdxio/hyperdx Coming from an observability nerd background, with Warren being SRE #1 at his last startup and me previously…

    Hey HN, I'm Zach, founder of Portal. Portal lets you share a live sandbox browser session as a link. Try it here: https://www.makeportals.com/try Instead of asking someone to sign up, install software, or book a demo for user research, onboarding, or sales, you send a link and they interact with the real product in a sandboxed browser environment, then you get session replays. Each viewer gets a fresh remote browser instance that starts from a defined state (URL, cookies, extensions, local files, etc). Sessions are isolated and expire automatically. The sessions have…

    I got tired of sharing AI demos with terminal screenshots or screen recordings. Claude Code already stores full session transcripts locally as JSONL files. Those logs contain everything: prompts, tool calls, thinking blocks, and timestamps. I built a small CLI tool that converts those logs into an interactive HTML replay. You can step through the session, jump through the timeline, expand tool calls, and inspect the full conversation. The output is a single self-contained HTML file — no dependencies. You can email it, host it anywhere, embed it in a blog post, and it works on mobile. Repo:…
