Software isn't written anymore. It's run.

K3 is mission control for agent-driven development.

Run agents, inspect every action, and control how your system evolves.

K3 Studio

Mission control for software

All your agents. One control plane.

Run the best coding agents in one place-native or external.

K3 integrates directly with leading models and tools, while maintaining a single system for execution, inspection, and control.

Mission Control

Every agent. Every task. Full visibility.

See everything in motion-what's running, what's waiting, and what just changed your system.

Step in when decisions matter.

Stay out when execution is clear.

You are always in control.

See how it works

Control the system. Not the tools.

One runtime, not a dozen tools

K3 replaces fragmented workflows with a single execution environment.

Agents, commands, and system state all operate from the same context-eliminating drift, duplication, and coordination overhead.

Execution you can shape

Define how work runs.

Automate flows, enforce constraints, and adapt behaviour in real time-without losing control of what's happening underneath.

Built for real environments

K3 connects directly to the tools, systems, and models your workflow depends on-while maintaining a single control layer over execution and outcomes.

For developers

Everything you need to run agent-driven systems

A complete environment for execution, control, and observability.

Kai Agent

Built inside the system. Not bolted onto it.

Kai operates with full awareness of the K3 runtime-able to interact with tools, state, and workflows directly.

It doesn't simulate execution.

It participates in it.
