Axe: 12MB Binary That Replaces Your AI Framework (Open Source)
What it is
Trending on Hacker News this week (162+ points). A single lightweight binary that handles AI agent orchestration, tool calling, and workflow execution without heavy frameworks like LangChain or CrewAI. For founders who've outgrown no-code platforms and want a fast, self-hosted AI agent runtime without dependency bloat.
Why we picked it
Represents the emerging trend toward lean, self-hosted AI infrastructure. Relevant for Module 5 students who want to deploy production agents without paying per-execution platform fees. The "12MB binary" pitch is compelling for bootstrapped founders.
How you might use it
Operations work is often invisible until something breaks. This fits the Run Smoother Operations workflow, which is about fixing the processes you run more than once a week. Pick one of those processes and test it there first.
