rrweb 1.0

The most popular open-source session replay library

rrweb 1.0 launched on July 6, 2021 with 120 votes, #373 of 3,502 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 5 years on.

What it does

Today we are very happy to annouce rrweb 1.0 is general availability! Highlights: - Support record same-origin non-sandboxed iframe. - Support record open-mode shadow DOM. - Implement the plugin API. - Very detailed recipes for developers.

Embeddable session replay infrastructure on rrweb, the open source standard. Unbranded SDK, ingest on your domain, replay through your API. Free tier included.

rrweb adds session replay to your product. Add one snippet, and rrweb handles everything from recording sessions to replaying them in your product, under your brand. Add replay to the product you already run, or build an entire product on the open recorder. These are the use cases teams already ship on rrweb. Attach the session behind every error to the observability view you build. One timestamped stream of DOM, clicks, console, and network. Connect funnels, friction signals, and behavior trends to the sessions that explain them, inside analytics you own. Record what a browser agent actually saw. Replay a failed run as DOM-level evidence beside the model and tool trace. Ship a reporter…from rrweb.com

    DriftDB – an open source WebSocket backend for real-time apps2023 · driftdb.com · ▲367

    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…

  • RePlaya – self-hosted browser session replay with live tailingJun 2026 · github.com · ▲50

    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, 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…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
