Show HN: OpenUser: Self-hosted user-persona tester for AI coding agents Recent hype about loop engineering made me realize that im missing one thing, and that is an agent that should be doing my job at the end of my loop: real user test i developing a huge b2b ecommerce project codebase. and for every new feature or fixes my job is always to test it on the browser. yuck. so i have made some research and there is TestSprite, but its not what i really want, i cant even self host it. so i built OpenUser. now i just engineer the loop with simple prompt: complete {feature} and use /openuser to test it. it store user persona, struggle, checkpoints, console logs, network logs. the agent has access to all and just fix everything. this is the real replacement of me at the end of the loop. everything runs locally, with any coding agents and model. try it: https://ift.tt/rdTFNAG npx openuser-cli June 24, 2026 at 12:03AM

Show HN: I gave Claude Code the keys to the Visual Studio debugger I use Visual Studio daily, and Claude Code only ships native integration for VS Code (annoying). So, I built the Visual Studio half myself. It's an unofficial extension that speaks Claude Code's undocumented IDE protocol. It started simple. Review Claude's edits in the real VS diff and accept or reject there, with no duplicate y/n prompt in the terminal, plus sharing the C# and C++ compiler errors with it directly. The infra I built for the extension allowed me to add the interesting part, the VS debugger. When you're paused at a breakpoint, Claude can read the call stack and locals, and with a toggle it can drive the debugger itself: set breakpoints, step, start and stop a session, and find a bug by running the code instead of reading it. There's a short walkthrough in the README where it catches a bug that never shows up in the output, by watching a counter fail to reset as it steps through a loop....

Show HN: Oak – Git replacement designed for agents Oak is a version control system I've been working on designed for agents ( https://oak.space ). It improves the speed and context your agents need when working on serious projects. With virtual mounts, agents locally and in the cloud no longer need a full copy of a repo to get working. You can work on many tasks in parallel without needing to download everything or fight worktrees. Version control shouldn't waste you or your agents time. It should be fast, creative and fun to make things with agents. Oak is still early in development. There's no Windows build and missing plenty of features (no CI, no issues, no comments). We still use GitHub Actions for building Oak now, but we've been fully bootstrapped on Oak with no Git backup for several months: https://oak.space/oak/oak .

Show HN: Selector Forge – browser extension for AI-generated resilient selectors Hi HN, I'm Ahmad from the Intuned ( https://intunedhq.com ) team. Today, we're releasing and open-sourcing Selector Forge ( https://ift.tt/p5U1FHk ), a browser extension that generates reliable CSS/XPath selectors using AI. You can use it to create a selector for a single element or for an array of elements. The selectors it creates are meant to be "semantic" and more resilient to page changes than what Chrome DevTool’s “Copy Selector” (and other similar extensions) give you. Those tend to hand you something brittle like `#top > div.w-100.ph0-l.ph3.ph4-m > h1 > span`, which can break with a minimal page change. Selector Forge aims for selectors that don't break as easily. Here are some selectors that Selector Forge created: `//div[@aria-label="Showing weekly downloads"]//p[@aria-live="polite"]` (item selector) and `//*[local-name()='svg' and @aria...
