Hi HN community, I’m Zach, founder and CEO of Warp, and am excited to show you Warp, a fast Rust-based terminal that’s easy to use and built for teams. As of today, Warp is in public beta and any Mac user can download it. It works with bash, zsh, and fish. The terminal’s teletype-like interface has made it hard for the CLI to thrive. After 20 years of programming, I still find it hard to copy a command’s output; I always forget how to use `tar`; and I always have to relearn how to move my cursor. To fix fundamental accessibility issues, I believe we need to start innovating on the terminal,…

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…

I built Fresh to challenge the status quo that terminal editing must require a steep learning curve or endless configuration. My goal was to create a fast, resource-efficient TUI editor with the usability and features of a modern GUI editor (like a command palette, mouse support, and LSP integration). Core Philosophy: - Ease-of-Use: Fundamentally non-modal. Prioritizes standard keybindings and a minimal learning curve. - Efficiency: Uses a lazy-loading piece tree to avoid loading huge files into RAM - reads only what's needed for user interactions. Coded in Rust. - Extensibility: Uses…

Hi HN, I’m Kiet, one of the creators of Onlook studio. I made this app that allows you to visually edit your locally running React app and write the code back to it in real-time. The purpose is to allow you to develop UI while fully owning your code the whole time. There are other visual builders out there but they either require you to upload your code to the cloud or some lengthy setup process. Onlook runs locally, deterministically, and only requires adding a plugin for the compile step (2 lines of config change). Technical details: This is technically a web browser that can point to your…

Hi HN! I've been working on a code editor and I think that it's mature enough to catch some interest. It's using a custom GPU accelerated GUI written in C++. Currently implements some interesting features: LSP, terminal, auto-completion, linters, formatters, custom keybindings, plugins and more. It's a hobby project but still intends to be an alternative to other popular code editors like Sublime, Kate, Lapce, Lite XL (and takes inspiration from them). The project was born as a playground for the GUI I'm developing (eepp GUI) and is advanced enough to currently be my main code editor, but…

Hey 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,…
