OpenBracket, a collaborative code editor for technical interviews
Hi everyone! At Fluxon, we found that we were't happy with existing solutions for collaborative coding with engineering candidates in our technical interviews. So we built OpenBracket.net—a simple code editor with no setup or log in needed—just share the link and start coding together. Our first version is now available for anyone to use. We’d love some feedback. Thanks!

In plain words
OpenBracket is a collaborative code editor designed for technical interviews. It allows interviewers and candidates to code together in real time by simply sharing a link, with no setup or login required. The tool addresses frustrations with existing interview solutions by prioritizing simplicity and immediate accessibility, making it easy for engineering teams to conduct remote coding assessments.

The collaborative code editor that gets out of your way.
OpenBracket is a collaborative code editor that gets out of your way, so you can focus on the problem — and person — in front of you. We’ve cleared the clutter, so candidates can focus on the task, not the tool. There’s no need to sign up, screen share or learn something new — just start coding. No setup required — just open a doc, share the link and start coding. Write and run code together in real time — as if you’re collaborating side-by-side. Work is saved automatically, so it’s easy to share for later review. Work together through problems faster with syntax highlighting, autocomplete and the ability to see collaborators’ cursors. OpenBracket allows for multiple collaborators for more…from openbracket.net

CodeCafé – A real-time collaborative code editor in the browser2025 · github.com · ▲81Hey guys! I’ve been working on a web app called CodeCafé—a collaborative, browser-based code editor inspired by VS Code and Replit, but with no downloads, no sign-up, and zero setup. You just open the link and start coding—together. The frontend is built with React and TypeScript, and the backend runs on Java with Spring Boot, which handles real-time editing via WebSockets. For syncing changes, I’m using Redis along with a custom Operational Transformation system (no third-party libraries!!!). The idea came after I found out a local summer school was teaching coding using Google Docs (yes,…

Talanoa▲346Hi 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…

Hey HN, I've been working on https://pornpen.ai, a site for generating adult images. Please only visit the site if you are 18+ and willing to look at NSFW images. This site is an experiment using newer text-to-image models. I explicitly removed the ability to specify custom text to avoid harmful imagery from being generated. New tags will be added once the prompt-engineering algorithm is fine-tuned further. If the servers are overloaded, take a look at the feed and search pages to look through past results.
