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.

Phoenix LiveView enables rich, real-time user interfaces with server-rendered HTML. No JavaScript needed for interactivity. Built on the BEAM VM for massive concurrency.
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.”
“Real-time UI without writing JavaScript. The BEAM VM handles millions of concurrent connections effortlessly.”
“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.”
“Server-rendered real-time UI is the sleeper approach. LiveView, HTMX, and similar tools challenge SPA dominance.”
“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.”
“LiveView proves server-rendered real-time UI is viable. For CRUD apps with real-time needs, it eliminates the SPA.”
