What is Mitsuro?

Mitsuro brings conversations, code sessions, and autonomous work into one connected workspace.

• Agent is the interactive experience for coding, questions, and project

work.

• Hive runs durable tasks that can continue in the background and recover

across restarts.

• Your server owns sessions, tools, and project access. Mobile, web,

desktop, terminal, and editor clients connect to the same source of truth.

Mitsuro works with multiple AI providers and keeps provider credentials under your control. Tool permissions remain explicit, and project data is stored by the Mitsuro server rather than split across client-only copies.

Ways to use it

| Surface | Best for | | --- | --- | | iPhone | Conversations, code sessions, Hive runs, reports, and remote tools | | Web | The full Mitsuro workspace in a browser | | Desktop | A native desktop window around the shared web workspace | | Terminal | Interactive work and direct server control | | Editor | Connecting compatible editors through ACP |

Highlights

• Stream conversations and tool activity as work happens.
• Resume saved sessions and recover interrupted work.
• Switch between supported providers and models without changing clients.
• Review approvals, errors, reports, and background runs from the same

workspace.

• Extend the agent with skills, plugins, MCP servers, and local extensions.
• Keep the server self-hosted and connect privately from your other devices.

Install

Download the installer, inspect it if desired, and run it:

curl -fsSLO https://raw.githubusercontent.com/honeycomb-Technologies/Mitsuro/main/install.sh
sh install.sh

The installer verifies the published SHA-256 checksum before installing a release.

Start the terminal app:

krusty

Start the server and web workspace:

krusty serve

Mitsuro is the product name. The installed krusty command remains available for compatibility with existing installations and automation.

Build from source

git clone https://github.com/honeycomb-Technologies/Mitsuro.git
cd Mitsuro
cargo build --release

See [Building and deployment](docs/operations/build-and-deploy.md) for platform requirements and client build instructions.

Development

The repository uses Rust for the core runtime and Expo/React Native for the shared client.

cargo check --workspace
cargo test --workspace
cargo clippy --workspace -- -D warnings
cargo fmt --all

For the mobile and web client:

cd apps/mobile
bun install --frozen-lockfile
npx tsc --noEmit
npx expo export --platform web

Project status

Mitsuro is under active development. Some internal package, executable, route, and storage identifiers still use the legacy krusty or mako names so existing installations keep working. Public product language and new links use Mitsuro, Agent, and Hive.
