Code pastes in local storage, shared via Web Sockets

I thought it would be great to share code snippets without saving them on a server, so I created http://mem.pe It allows you to paste code and save it in your browser's local storage. When you share the URL of the pasted code, other people will connect to it via web sockets. For example, this http://mem.pe/#sge/5 you will be pulling from my browser. I'll keep it open for a while. If you close the web app, your code paste will not be available for anyone to see, until you open the web app again. This is obviously, not suitable for using at forums and other places…

In plain words

Mem.pe is a code sharing tool that stores snippets in a browser's local storage rather than on a server. Users paste code, then share a URL that connects others via WebSockets to view the snippet directly from their browser. The paste remains available only while the creator's browser session is active, making it suitable for temporary sharing in real-time communication like IRC and chat, but not for persistent online storage. The code is open source on GitHub.

  • Memex is a Claude Code alternative built on Rust+Tauri for vibe coding2025 · memex.tech · ▲86

    Hi HN, TL;DR Memex is a cross-platform desktop app for vibe coding. Think ChatGPT + Claude Code rolled into one. Why we built it: We love chat tools like Perplexity and ChatGPT. We also love coding agents, like in Cursor and Windsurf. We don’t like that web-based app builders are opinionated about tech stack and we can’t run them locally. So, we built Memex to be a chat tool + coding agent that supports any tech stack. What it can do today: Claude Code-like coding. Agentic web search / research. Pre-built templates (e.g. fullstack, iOS, python + modal, etc). Inline data analysis + viz.…

  • Mem0 Browser Extension: Shared Memory Across ChatGPT,Claude,Perplexity2024 · github.com · ▲34

    Hey HN! We're Deshraj and Taranjeet. We've been building working on a startup called Mem0, building an open-source memory layer for AI apps and agents (https://news.ycombinator.com/item?id=41447317). We also kept running into our own daily frustrations with AI assistants forgetting everything between conversations. Over a weekend, we decided to hack together a Chrome extension to solve this for ourselves. The problem was simple: we were constantly re-explaining our context across platforms when switching between ChatGPT, Claude, and Perplexity. Start a coding discussion in…

    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…
