  3. memX

    A real-time shared memory layer for multi-agent LLM systems.

    Project mention: Show HN: MemX – Shared memory for LLM agents | news.ycombinator.com | 2025-06-26

    Hey everyone — I built this and wanted to share as its free to use and might help some of you:

    https://mem-x.vercel.app

    GH: https://github.com/MehulG/memX

    memX is a shared memory layer for LLM agents — kind of like Redis, but with real-time sync, pub/sub, schema validation, and access control.

    Instead of having agents pass messages or follow a fixed pipeline, they just read and write to shared memory keys. It’s like a collaborative whiteboard where agents evolve context together.

    Key features:

    Real-time pub/sub

    Per-key JSON schema validation

    API key-based ACLs

    Python SDK

    Would love to hear how folks here are managing shared state or context across autonomous agents.

  4. svelte-retag

    Light DOM custom element wrapper for Svelte 3 and 4 with slots, context and Vite HMR support

  5. contextual-logging-nodejs

    Contextual logging in Node.js with Pino and AsyncLocalStorage

  6. react-component-shell

    react-component-shell is a package that allows you to quickly and easily create react-contexts and implement state management.

  7. context-simplifier

    Utility to simplify context api usage in react

  8. svelte-context-deeznuts

    Set and get typed component contexts
