Agent Ecosystem OS · Self-hosted · Model agnostic

One platform.
Every agent.

Kaptain is the operating layer for your agents. Build specialized agents, connect them through a shared communication layer, assign work across the models you choose, and keep every workflow under your control.

// YOUR ECOSYSTEM

Your ecosystem,
under your control.

Kaptain gives agents a common home: a place to communicate, retain useful context, receive work, and remain observable while you decide how each workflow should run.

01 · ROUTING

Granular control

Assign work to premium, lighter, cheaper, or local models according to the task and your priorities.

02 · MEMORY

Persistent continuity

Retain useful context and build reusable knowledge across ongoing work.

03 · COMMUNICATION

Agents that connect

Talk to Kaptain in its chat, to each kapsule in its own chat, and let agents call each other when you allow it.

04 · OBSERVABILITY

Visible by design

Inspect traces, review approvals, and understand what your agents are doing.

// MODEL-AGNOSTIC WORKFLOWS

Move work where
it belongs.

Use the right model for the right task. Kaptain lets you create workflows across local and cloud models while keeping assignment logic, agent tools, and execution boundaries in your hands.

// BUILD AND COMMUNICATE

Create your own agent.
Or a swarm.

An Agent is one specialist with its own behaviour, model, tools, workspace, memory, tasks and schedule. A Swarm is a kapsule allowed to bring in workers: a pool of agents with Kaptain's plumbing directly attached, working together on your task or workflow: shared board, handoffs, evidence-gated workers, one permission ceiling. Work with either from the Kaptain chat or from the kapsule's own chat.

Kapsule · release-notesclaude-cli · skill: release-notes-style
A Kapsule named release-notes, running on a Claude CLI model with a house-style skill, has drafted customer-facing release notes for version 2.4.0 from the workspace changelog and incident log, citing incident numbers, and lists its notes on the draft.
An agent that knows your house style writes the notes from your own records. You review, it ships.
// TASK OFFLOADING

Delegation, defined by you.
Frontier reasoning when it counts.

Delegation in Kaptain is a router you configure, not a rule we impose. Point it one way and a powerful model, such as a Claude or Codex CLI, becomes the delegate: called only when a task needs frontier reasoning, while a light local model carries the rest. Point it the other way and work fans out across your own cluster of local and cloud models, split by task and by load. Local, remote or cloud, you decide what handles what. Kaptain gives you the plumbing to connect or add those resources without the hassle.

TOKEN USAGE

Model-agnostic delegation can reduce unnecessary premium-model usage by keeping routine work, evidence compression, and repeatable helper tasks on the routes you select.

// INSPECT THE WORK

See the flow.
Understand the work.

BlackBox Traces shows request flow, models, context, tools, token totals, errors, and response previews. God's Eye View maps files, folders, functions, routes, symbols, and relationships.

Nothing hidden. Tap a turn and scroll through the exact context sent, every tool call, and the reply.
God's Eye file atlas of a project: index status, symbol search, a folder graph radiating from the project root, and an inspector panel.
Your project as a graph you and your agents both navigate.
// DEVIEW

Your developer view.
An IDE inside Kaptain.

Deview is the IDE experience built into Kaptain: the project tree, an editor with Read, Edit and Preview modes, and project-wide search, all on the same root your agents work in. Open the file an agent just changed, fix a line, save, and keep your place. No second copy of your project, no switching windows.

Deviewworkspace · src/ratecard/ratecard.go
Deview: the project tree on the left with the sample repository's folders, and a Go source file open in the editor with line numbers and a Read/Edit switch.
Edit and save in the same root your agents work in. No copy of the truth.
