Replicas▲239Hey HN! I'm Connor, creator of Replicas. I'm a heavy Codex/Claude Code user, and I wanted to hand off tasks to agents like I would to an engineer - kick something off before work, let it scaffold while I'm at lunch, even come back to a ready PR. The problem: existing alternatives use workspace VMs that are black boxes. I have no access to any of them - they can't run tests, read logs, or use tools like the Playwright MCP (which I use to verify agents actually fixed what they claim to fix). Replicas gives agents real cloud workspaces where they can: - Run your test suite and read the…

I like to use org files a lot, but I wanted some way to browse and edit them on my phone when I'm out. Yesterday I used Codex to make this simple one-file web server that just displays all my org files with backlinks. It doesn't have any authentication because I only run it on my wireguard VPN. I've been having fun with it, hopefully it's useful to someone else!

This project is a tool for engineers who live in the terminal and are tired of losing their command history to ephemeral servers or fragmented `.bash_history` files. If you’re jumping between dozens of boxes, many of which might be destroyed an hour later, your "local memory" (the history file) is essentially useless. This tool builds a centralized, permanent brain for your shell activity, ensuring that a complex one-liner you crafted months ago remains accessible even if the server it ran on is long gone. The core mechanism wants to be a "zero-touch" capture that happens at the connection…

Hi HN, i am Dimitris, I have been using Claude Code and Codex agents, for some time now from the beggining i had been using them from inside my terminal mainly for coding. For the past 3 years i kept building so i have a homelab and a business server, which already has a lot of vms, so a lot of things to manage. So i decided to start building my own ideal version of using claude code, and codex flexibly and connect them easily with all my vms and infra but at the same time keep using them for coding, and as a personal assistant for daily use. So for the past months I built OtoDock. Its a…

Hello HN! Sebastian here from Schub. We just open-sourced a new project I've been working on, called legacy-use, and I’d love to get your thoughts. At Schub, we’ve been building agents that automate legacy Windows software (healthcare systems, finance tools, EHRs), the kind of stuff that’s mission-critical but hasn’t changed since Windows XP. These apps have zero APIs and usually require humans clicking around all day. So we built legacy-use, an agentic API layer for any desktop app. Well, technically any software. Legacy-use lets AI agents control GUI-based software by emulating mouse and…

If you had to build a context window manager in 24h, would you stick to the existing model or come up with something better? Here's what I did: 1. Built a proxy that intercepts Codex's calls to OpenAI and rewrites them on the fly. 2. Replayed 3,807 rounds of SWE-bench Verified traces through it: avg prompt 44k → 6k tokens (-87%). 3. Posted it to HN to get the next reduction applied to my confidence interval — starting with the inevitable "How about accuracy?" npx -y pando-proxy · github.com/human-software-us/pando-proxy

A friend and I built this as a side project to help us collaborate on files with our agents. Claude / Codex kept outputting .md and .html files which are great until we needed to share them, so we built this small website to help with that. Agent can either use an HTTP + Skill or an MCP which also uses MCP Apps to add widgets to Claude Desktop / Mobile chat. Would love any feedback and hopefully this helps someone else as it did us!
