About DeepSeek Harness
DeepSeek Harness is an open-source agent runtime built specifically for developers and AI engineers seeking modular control over their AI systems. Operating under the core philosophy that everything is a plugin, this platform delivers granular control for building, testing, and deploying custom AI agents.
With DeepSeek Harness, developers can customize and swap virtually any component in the architecture. Models, tools, prompts, storage mechanisms, the core agent execution loop, and even the user interface itself function as modular plugins. This composable setup allows developers to assemble highly tailored agent presets and custom profiles to suit specific project needs.
Beyond customization, the framework provides robust features for programmatic tool calling and session management. By keeping a comprehensive event log of all actions, developers can easily recover and replay agent sessions, making the testing and debugging process significantly more streamlined.
Pros of DeepSeek Harness
- Fully open-source developer tool
- Highly composable architecture where everything from the UI to the agent loop is a plugin
- Comprehensive event logging for easy recovery and replay
- Supports programmatic tool calling and customized agent presets
Cons of DeepSeek Harness
- Requires development expertise to configure and compose plugins
- Highly modular setup may require more initial configuration compared to turnkey solutions
- No pre-configured hosted cloud offering mentioned

Yes. DeepSeek Harness maintains a comprehensive event log of all actions, enabling developers to easily recover and replay agent sessions during testing and debugging.
How are tools executed within the harness?
The platform supports programmatic tool calling, allowing for the seamless execution and integration of external tools alongside your configured agent presets.
About Vizhi
Vizhi (named after the Tamil word for 'eye') is an open-source hardware mission control interface engineered for developers managing concurrent AI coding sessions. Created by indie developer Ravi Shankar during OpenAI Build Week, Vizhi addresses a modern workflow bottleneck: as autonomous coding assistants handle the bulk of software generation, developer attention shifts towards monitoring, approving, and steering multiple terminal processes. Vizhi maps these supervisory tasks directly onto physical hardware via the Logitech MX Creative Keypad, turning its dynamic LCD keys into a dedicated command deck. The system tracks up to six active Codex CLI sessions simultaneously across macOS terminal tabs, binding each session to a persistent LCD key showing its live status and context consumption. When an AI agent reaches a permission checkpoint or command execution gate, the corresponding key lights up in amber or red, enabling instant, one-press approvals directly from the keypad without switching windows. Beyond physical controls, Vizhi integrates offline Whisper-based voice dictation to send spoken prompts straight to agents, backed by TTY-verified safety delivery. For developers without the physical Logitech keypad, Vizhi includes a local browser-based companion dashboard that mirrors session supervision entirely offline.
Pros of Vizhi
- Transforms physical keypad hardware into an intuitive, glanceable control deck for up to six simultaneous Codex CLI sessions
- One-touch hardware approval keys reduce window-switching fatigue during multi-agent workflows
- Completely local and private architecture with on-device Whisper transcription and token-protected TTY verification
- Includes a browser-based local dashboard fallback for developers without the Logitech MX keypad
- Open-source and highly customizable key-binding configuration
Cons of Vizhi
- Full hardware experience requires a specific peripheral (the Logitech MX Creative Keypad)
- Currently tailored specifically to macOS and Apple Terminal environments
- Requires manual local setup spanning multiple toolchain components
Frequently Asked Questions
What is Vizhi and how does it help developers?
Vizhi is an open-source supervisor dashboard that connects Codex CLI agent sessions to the Logitech MX Creative Keypad, allowing developers to monitor active sessions, approve terminal actions with one press, and issue voice prompts.
Do I need a Logitech MX Creative Keypad to use Vizhi?
No. While the system is optimized for the physical LCD keys of the Logitech MX Creative Keypad, Vizhi includes a local browser dashboard that provides full session monitoring and controls on your computer screen.
How does voice prompting work in Vizhi?
Vizhi features a dedicated Voice key powered by local Whisper transcription. Spoken instructions are transcribed on-device without cloud API dependencies and sent directly to the targeted agent terminal.
Is Vizhi safe to use for terminal command approvals?
Yes. Vizhi runs entirely on your local machine and uses token-protected, TTY-verified approval delivery with visual color-coded badges to guard against unauthorized or accidental command executions.
