In plain words

Replay is a browser-based debugging tool that records website sessions for later inspection. Developers can capture interactions, then review them using familiar developer tools to identify and diagnose bugs. The tool allows users to share recorded replays with teammates and collaborators, making it easier to document and communicate issues during bug reporting and troubleshooting.

Connect a GitHub repo for continuous testing, or drop in a URL to test on demand. Replay QA finds real bugs and gives your coding agent the root cause and fix.

Add the link to a Github repo for continuous testing, or drop in a URL for a web app for on-demand testing. Replay QA explores your app, records every session, finds real bugs, and gives your coding agent the root cause and fix. AI coding tools have compressed development cycles from weeks to hours. A solo founder or a small team can now ship a full web app in a day. But the way we test software hasn't changed — it still requires engineers to write test suites, QA teams to run them, and someone to triage what breaks. The result: AI-built apps ship without meaningful test coverage. Internal tools get deployed with no QA layer at all. And the bugs your users hit are the first signal that…from replay.io

    Hey HN, I wanted to show you a product a small team and I have been working on for 4 years. https://jam.dev It’s called Jam and it prevents product managers (like I used to be) from being able to create vague and un-reproducible bug tickets (like I used to create). It’s actually really hard as a non-engineer to file useful bug tickets for engineers. Like, sometimes I thought I included a screenshot, but the important information the engineer needed was what was actually right outside the boundary of the screenshot I took. Or I'd write that something "didn't work" but the engineer…

    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…
