Why Zetelton exists

A simple codebase, built to be hyper-customizable. Zetelton is an open agent foundation for teams that need reliable automation.

Zetelton is an open agent foundation for teams that need reliable automation: an auditable runtime, first-class CLI tooling and documentation you can follow.

This is the story behind the project — the same one you see on the landing page, in article form.

A simple codebase, built to be hyper-customizable

Zetelton is a small runtime with a cleanly separated architecture: tools, memory and execution are each their own layer — easy to read, easy to replace. You start simple, then customize as deep as you need to, without ever having to work around the system.

Start small.

A minimal codebase you can read in an afternoon, not an ecosystem to learn first.

Clean separation.

Tools, memory and execution are independent layers — change one without breaking the others.

Hyper-customizable.

Replace any part of the pipeline without fighting the framework.

Keep it practical.

Simple by default, deep when you need it.

Get involved

Zetelton is built in the open. Star the repo, open an issue, or bootstrap your first agent with zetelton-init — everything is public.
