2026 Agentic Engineering Stack

Emil Ingemar Karlsson — 2026 Agentic Engineering Stack emilingemarkarlsson.com · self-hosted · ~€35/month

Paperclip-first cockpit · LangGraph 24/7 orchestration · capability-scoped agents (not org-chart). Emil steers kanban; LangGraph polls todo-issues, plans via LiteLLM, triggers agent heartbeats; nothing ships without approval-webhook + Telegram.
