Agent Kernel is a minimalist framework that gives AI agents persistent state using just three Markdown files — one for memory, one for plans, and one for context. No database, no complex infrastructure. Works with any LLM provider and keeps agent state human-readable and version-controllable.

Liveblocks provides real-time collaboration APIs — presence, cursors, comments, notifications, and text editing. Drop-in React hooks for multiplayer experiences.
Reviewer scorecard
“The simplicity is the feature. Three Markdown files, git-trackable, human-readable. No ORM, no migrations, no database to manage. For agents that need persistent state without infrastructure overhead, this is the pragmatic choice. I would pick this over LangGraph's complexity any day.”
“React hooks for real-time presence, cursors, and collaborative editing. Makes adding multiplayer features trivial.”
“Agent Kernel proves that the best agent infrastructure might be no infrastructure at all. Markdown as a universal state format means your agent's memory is inspectable, debuggable, and portable. This "files over frameworks" philosophy will age well.”
“Every SaaS app will add real-time collaboration. Liveblocks is the infrastructure layer that makes it practical.”
“Cute for prototyping but falls apart at any real scale. No concurrent access handling, no structured queries over memory, no way to prune state as it grows. You will outgrow three Markdown files the moment your agent needs to remember more than a weekend's worth of conversations.”
“Building real-time collaboration from scratch is brutal. Liveblocks abstracts the hard parts with a clean API.”
