Persistent
Your environment keeps its state between sessions. Close it, reopen it tomorrow, and everything is exactly where you left it.
Now in private beta
Persistent, reproducible dev environments — built AI-first.
Ringleader gives every developer and every AI agent a workspace that is always ready to run, identical everywhere, and shared without setup.
Why Ringleader
"Works on my machine" is the most expensive sentence in software. Ringleader makes the environment itself persistent, reproducible, and shareable — for people and agents alike.
Reproducible
Every environment is defined in code, so it rebuilds identically on any machine — yours, a teammate's, or an agent's.
AI-first
Agents get a real, first-class environment with the same guarantees a human developer has. No ephemeral sandboxes, no drift.
Shareable
Hand an environment to a colleague or an AI agent and they get the very same state — no setup, no 'works on my machine'.
Fast to start
Spin up a ready-to-run workspace in seconds instead of spending days on onboarding and dependency wrangling.
Secure by design
Isolated, auditable environments keep secrets and state contained, so what an agent does is reviewable and contained.
Get running in minutes
Describe your environment in a YAML file and apply it — declarative, just
like kubectl. It stays persistent — close your laptop and pick up exactly
where you left off, or hand the same state to a teammate or an AI agent.
