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.

Playwright by Microsoft provides cross-browser end-to-end testing with auto-waiting, tracing, and codegen. Supports Chromium, Firefox, and WebKit.
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.”
“Best E2E testing framework. Auto-wait, trace viewer, and codegen eliminate the biggest pain points of browser testing.”
“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.”
“Playwright is becoming the standard for browser automation beyond testing — AI agents, scraping, and verification.”
“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.”
“Replaced Cypress in most serious projects. Multi-browser support and the trace viewer are genuine advantages.”
