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.

Retool is a low-code platform for building internal tools — dashboards, admin panels, CRUD apps. Connect to any database or API with drag-and-drop components.
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.”
“Build admin panels in hours instead of weeks. SQL queries, API connections, and components just work together.”
“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.”
“AI-generated internal tools will commoditize this space, but Retool's head start and enterprise adoption provide a moat.”
“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.”
“For internal tools that don't need to be beautiful, Retool eliminates weeks of dev time. Genuinely useful.”
