I Built a CLI for AI Projects – Here’s My Experience

AI development is moving at breakneck speed. New models, APIs, and frameworks pop up every month, and keeping up can feel overwhelming. As someone who frequently prototypes AI applications, I found myself constantly rebuilding the same project scaffolding: setting up API keys, installing dependencies, creating Streamlit UIs, and integrating vector databases. So I thought: Why am I doing this manually every time? That’s when RunKit was born – a CLI tool that lets developers scaffold AI projects in seconds, not days. Here’s what I learned while building it. Why I Built a CLI for AI Projects Every AI project starts the same way: Decide on an LLM (Claude, Gemini, or a local model like Ollama) Set up environment variables and API keys Install dependencies Create a basic UI (usually Streamlit or FastAPI) Add optional features like caching, conversation memory, or a vector database I was repeating this setup so often that I started copy-pasting boilerplate code.

I Built a CLI for AI Projects – Here’s My Experience

AI development is moving at breakneck speed. New models, APIs, and frameworks pop up every month, and keeping up can feel overwhelming. As someone who frequently prototypes AI applications, I found myself constantly rebuilding the same project scaffolding: setting up API keys, installing dependencies, creating Streamlit UIs, and integrating vector databases.

So I thought: Why am I doing this manually every time?

That’s when RunKit was born – a CLI tool that lets developers scaffold AI projects in seconds, not days. Here’s what I learned while building it.

Why I Built a CLI for AI Projects

Every AI project starts the same way:

  • Decide on an LLM (Claude, Gemini, or a local model like Ollama)
  • Set up environment variables and API keys
  • Install dependencies
  • Create a basic UI (usually Streamlit or FastAPI)
  • Add optional features like caching, conversation memory, or a vector database

I was repeating this setup so often that I started copy-pasting boilerplate code. But maintaining multiple AI projects like this was a nightmare. Dependencies would change, API requirements would shift, and suddenly my old setups were outdated.

So I built RunKit: a CLI tool that lets you do this with a single command:

pip install run-kit
run-kit my-ai-project

And boom! A ready-to-run AI project is generated with best practices, customizable features, and a clean architecture.

The Challenges of Building a CLI

Building a CLI isn’t just about automating tasks; it’s about making the experience smooth for users. Here are some of the challenges I faced:

1. Making the CLI Intuitive

Nobody wants to read a 10-page manual to use a CLI. The goal was to make it as frictionless as possible. That’s why RunKit asks interactive questions:
