About Heym

Heym is a source-available platform designed for building, executing, and managing agentic AI systems directly on your own infrastructure. It enables teams to construct complex multi-agent workflows visually while retaining full sovereignty over their models, data, and credentials.

With Heym, users can seamlessly connect external data sources and tools, integrate specialized coding agents such as Codex and OpenCode, and insert human-in-the-loop approval stages at critical operational junctions. This visual approach allows both technical and non-technical stakeholders to collaborate effectively when designing intelligent agent pipelines.

To maintain operational confidence, Heym features robust built-in observability tools. Users can inspect execution traces, monitor costs, analyze response latency, and run performance evaluations for every execution. Completed workflows can be deployed flexibly as web portals, standard APIs, or Model Context Protocol (MCP) tools.

Pros of Heym

  • Source-available software that can be self-hosted on your own infrastructure
  • Visual workflow builder for constructing multi-agent systems
  • Built-in observability including traces, cost tracking, latency metrics, and evaluations
  • Flexible deployment methods as portals, APIs, or MCP tools
  • Supports human-in-the-loop approvals and integrations with coding agents like Codex and OpenCode

Cons of Heym

  • Requires technical setup and maintenance for self-hosting on private infrastructure
  • Fewer managed cloud convenience features compared to fully hosted SaaS alternatives

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.
