About npm i -g hotcell
npm i -g hotcell is a self-hostable sandbox SDK inspired by the Cloudflare Sandbox SDK, designed specifically to provide local sandboxes for AI agents on Mac, Linux, and bare metal devices.
Built to be exceptionally easy to use for both human engineers and AI agents, Hotcell offers granular control over resource capacity and token spending per sandbox. It enhances security by allowing you to default-deny network egress while still permitting access to LLM providers. Furthermore, your master API keys never enter individual sandboxes directly; instead, Hotcell generates ephemeral, per-sandbox tokens that automatically terminate when the sandbox stops.
Pros of npm i -g hotcell
- Works on any device including Mac, Linux, and bare metal
- Self-hostable SDK inspired by Cloudflare Sandbox SDK
- Enhanced security with default-deny egress and access control for LLM providers
- API keys are protected via ephemeral, per-sandbox tokens that die upon sandbox termination
- Full control over capacity and token spend per sandbox
Cons of npm i -g hotcell
- Requires self-hosting setup on local or bare metal infrastructure
- Limited to environments supported by the SDK (Mac and Linux)
- Requires command-line proficiency via npm installation

About Vizhi
Vizhi (derived from the Tamil word for "eye") acts as a specialized mission control dashboard for monitoring and managing your Codex CLI sessions. Developed by indie developer Ravi Shankar, Vizhi is designed to keep an eye on active execution sessions so developers don't have to constantly tab back and forth into their terminal windows.
The tool provides deep integration with hardware controllers like the Logitech MX Creative Keypad, enabling users to keep track of up to six live sessions simultaneously. Through this physical interface, developers can perform quick action executions, such as one-press session approvals, and issue local voice prompts powered by Whisper.
For developers who do not own a hardware keypad, Vizhi provides a local browser dashboard that offers visibility and control over active sessions. As an open-source developer tool available on GitHub, Vizhi fits seamlessly into terminal-centric AI development workflows.
Pros of Vizhi
- Monitors up to six live Codex CLI sessions simultaneously
- Integrates with Logitech MX Creative Keypad for tactile, one-press approvals
- Supports local Whisper voice prompts for easy command input
- Offers a local browser dashboard for users without a physical keypad
- Open-source developer tool available on GitHub
Cons of Vizhi
- Full physical experience requires a specific device (Logitech MX Creative Keypad)
- Designed specifically around Codex CLI workflows rather than general terminal tasks
