Gantry
Get started

Agent-ready development environments

One command.
The whole stack.

Gantry coordinates native processes, containers, secrets, and certificates, then gives developers and AI agents one truthful map of what is running.

01 Dynamic ports
No collisions
02 Machine-readable
from day one

01 / THE PROBLEM

“Works on my machine” is even worse when the new developer is an agent.

README archaeology. Stale environment files. Mystery ports. Logs written for people and scraped by machines.

Gantry replaces that uncertainty with a reproducible execution graph and a stable JSON contract.

02 / ONE EXECUTION GRAPH

Your repository,
materialized.

Plain YAML goes in. A healthy local stack and its complete state map come out.

01
Define

Describe apps, infrastructure, secrets, and dependencies in Gantry.yaml.

02
Resolve

References become graph edges. Dynamic ports and generated values bind at runtime.

03
Run

Native tools and OCI containers start concurrently, gated by real health checks.

04
Expose

Humans get a live terminal tree. Agents get one canonical JSON state map.

03 / BUILT FOR TWO USERS

A clear interface
for humans.
A contract for agents.

No log scraping. No guessing which service owns which port. Gantry exposes health, URLs, process IDs, and resolved environment values in a stable structure.
