overview

What is dshbase?

dshbase is an AI agent framework tool developed by DeepSeek that enables developers and agent builders to construct flexible and extensible AI agents. It operates on an 'everything is a plugin' philosophy, allowing tools, capabilities, and integrations to be installed as npm plugins rather than being part of the core system. DeepSeek Harness (DSH) provides a foundation for building and running AI agents, integrating various functionalities as plugins, and includes core services such as model adapters, tools, persistence mechanisms, a sandbox environment, approval policies, settings management, credential handling, and telemetry. The framework was released in developer preview in August 2026, with its initial version reported as v0.1 (package metadata 0.1.0-rc.5 as of August 13, 2026). DeepSeek has indicated that compatibility-breaking changes are expected during this preview phase.

Key Features of dshbase

DeepSeek Harness (dshbase) is distinguished by its modular architecture and comprehensive plugin ecosystem, providing developers with granular control over agent capabilities. Its core design principle ensures that all functionalities are externalized as npm plugins, fostering flexibility and extensibility.

  • "Everything is a Plugin" Architecture: All capabilities, tools, and integrations are installed and managed as npm plugins.
  • Extensive Plugin Ecosystem: A growing directory with over 120 plugins across categories like UI enhancements, sessions, tools, and workflows.
  • Core Services: Provides essential services for AI agent development, including model adapters, persistence, sandbox, approval policy, settings, credentials, and telemetry.
  • Advanced Terminal UI (dsh-tianshu-tui): Offers an interactive command-line interface with features like slash command menus, clipboard/image pasting, external editor integration, vim keybindings, session persistence, and validation gates.
  • Open Source: The framework is open source, allowing community contributions, auditing, and extensions.
  • Developer Preview Release: Launched in August 2026, with version v0.1 (0.1.0-rc.5), indicating active development and expected compatibility changes.
  • Tool Plugins: Includes specific tools like dsh-tool-stat for descriptive statistics, percentiles, and correlation using zero-dependency pure functions.

use cases

Who Should Use dshbase?

dshbase is primarily designed for developers and agent builders who require a highly customizable and extensible framework for creating AI agents. Its open-source nature and plugin-first architecture cater to those seeking alternatives to proprietary solutions and who value community-driven development.

  • Developers building flexible and extensible AI agents using a plugin-first architecture.
  • Agent Builders developing open-source agent solutions as an alternative to proprietary frameworks.
  • Teams managing complex agent systems with diverse capabilities like file systems, shells, and permissions.
  • Developers deploying agents across various environments, including web and headless modes.
  • Third-party developers enabling extensions and custom capabilities without modifying the core framework.

how to use

How to Use dshbase

To begin using dshbase, developers typically install the core framework and then add desired capabilities as npm plugins. The framework's design emphasizes modularity, allowing users to tailor their agent's functionality precisely.

  • 1Install the core DeepSeek Harness framework via npm.
  • 2Browse the dshbase plugin directory to identify required tools and capabilities.
  • 3Install specific plugins (e.g., dsh-tianshu-tui, dsh-tool-stat) using npm.
  • 4Configure agent settings, credentials, and approval policies within the framework.
  • 5Develop custom AI agent workflows by integrating installed plugins and DeepSeek API models.
  • 6Deploy agents in desired environments, leveraging the framework's web and headless modes.

pricing

dshbase Pricing & Plans

DeepSeek Harness itself is an open-source framework and is free to use. However, users will incur costs for accessing the underlying DeepSeek API, which is necessary for utilizing models such as V4-Pro. These API prices are determined and set by DeepSeek.

  • DeepSeek Harness (Framework): Free (open source)
  • DeepSeek API: Contact sales for pricing details (required for model access)

Pros

  • +Highly flexible and extensible due to its 'everything is a plugin' architecture.
  • +Leverages the familiar npm ecosystem for managing and installing capabilities.
  • +Open-source core allows for community contributions, auditing, and deep customization.
  • +Provides a robust set of core services essential for AI agent development.
  • +Offers advanced UI plugins like dsh-tianshu-tui for enhanced developer experience with features like TDD and session persistence.
  • +Avoids monolithic core systems, allowing developers to install only necessary tools.

Cons

  • −Currently in developer preview (v0.1), meaning compatibility-breaking changes are expected.
  • −Requires separate payment for DeepSeek API access to utilize AI models.
  • −As a 'hackable harness substrate,' it may require more hands-on development compared to more mature, out-of-the-box solutions.
  • −Comprehensive user reviews and widespread reception are still emerging due to its recent release in August 2026.
  • −Primarily targets developers and agent builders, potentially having a steeper learning curve for non-technical users.

dshbase vs Competitors

DeepSeek Harness (dshbase) differentiates itself in the AI agent framework landscape through its 'everything is a plugin' architecture and reliance on the npm ecosystem. This approach offers a distinct alternative to frameworks with more monolithic designs or different plugin paradigms.

1
LangChainOn Stork

Provides a comprehensive framework for building LLM applications, including agents, chains, and tool integration, with a strong focus on composability.

LangChain offers a broader ecosystem and supports both Python and JavaScript, but its extensive abstractions might introduce more complexity compared to DSHbase's simpler, npm-plugin-centric approach.

2
LlamaIndexOn Stork

Specializes in data ingestion, indexing, and retrieval for LLM applications, making it ideal for agents that need to interact with diverse data sources.

While both support agents and tools, LlamaIndex is more focused on data-centric LLM applications and RAG, meaning its tool integration is often geared towards data interaction rather than arbitrary npm-based capabilities like DSHbase.

3
CrewAIOn Stork

Focuses on orchestrating multiple AI agents to work together on complex tasks, enabling collaborative problem-solving.

DSHbase emphasizes individual agent capabilities via npm plugins, whereas CrewAI's strength lies in defining roles, tasks, and collaboration patterns for multiple agents, which is a higher-level abstraction and requires a different approach to agent design.

4
Semantic Kernel↗

Provides a lightweight SDK for integrating AI capabilities into existing applications, with a strong emphasis on 'plugins' (skills) that can be chained together.

While both use a plugin concept, DSHbase uses npm plugins, suggesting a JavaScript/TypeScript focus. Semantic Kernel is primarily C# and Python, and its 'plugins' are more about defining reusable AI functions and connectors rather than arbitrary npm packages, which might require adapting to its specific plugin model.
