Official listing: built and published by DeepSeek. More from DeepSeek

Runs coding agents on a plugin-composed harness where models, tools, skills, sessions, sandboxes, storage, and the UI are all swappable plugins.

Skills

Plugin Composition
Swaps models, tools, skills, sandboxes, and storage backends through one uniform plugin interface without forking the harness.
Session Persistence
Checkpoints agent session state so long-running tasks resume across restarts and survive switching the underlying model.
Sandboxed Execution
Executes agent-generated commands and code inside pluggable sandbox backends isolated from the host filesystem.
