Web UI for Gemini CLI + Gemini Code Assist — The New Era of AI Powered Development

Most devs still think Gemini CLI is only terminal based…

But actually, that era is gone. Now you can use Gemini CLI in two powerful ways:

1. A full browser based Web UI (Gemini-CLI-UI community project)
2. Gemini Code Assist inside VSCode which generates project files + code automatically

Both together literally turn Gemini into a full AI Developer Platform — not just a command line tool.

This is a MASSIVE productivity unlock

Prerequisites- for Gemini-CLI-UI

Before you setup the Web UI, make sure you have:

1. Node.js v20+ installed
2. Gemini CLI already installed & configured

Installation Steps (super simple)

git clone https://github.com/cruzyjapan/Gemini-CLI-UI.git
cd Gemini-CLI-UI
        

npm install
        

cp .env.example .env
# Edit the .env file with your preferred configs
        

npm run dev
        

Now open browser http://localhost:4009

Your Gemini Web UI Dev Cockpit is LIVE.

Getting Web Access for Gemini CLI

You have 2 ways:

Option 1 (Recommended) — Free Tier Google Login

When you launch Gemini CLI → choose “Login with Google”

• 60 req/min free
• 1000 req/day
• Access to Gemini 2.5 Pro
• 1 Million token context

Option 2 — API Key

export GOOGLE_API_KEY="YOUR_API_KEY"
        

You can get this from Google AI Studio.

Key Features You Get in UI

• Fully responsive (desktop / tablet / mobile)
• Interactive chat + code conversation
• Built-in shell terminal
• File explorer with live syntax highlighted editing
• Git integration + commit inside UI
• Session management (resume anytime)

This is way more than just a “frontend” — this makes Gemini projects continuous.

How to Use Gemini CLI Web UI to Ask & Generate Code

Once your Web UI is running at http://localhost:4009, you can talk to Gemini just like you do in terminal — but in visual mode.

You can do:

• ask questions
• ask it to modify code
• ask it to generate new files
• ask it to create entire features end-to-end

Examples you can type inside the chat window:

Example prompts you can use:

Important Security Note

By default all Gemini CLI tools are disabled. You must manually enable only what you need. Click the ⚙️ gear icon (sidebar) → toggle tool access as required.

This prevents accidental dangerous operations. This is enterprise-grade thinking.

Gemini Code Assist Extension inside VSCode

If you want a full hybrid workflow — browser UI + terminal + IDE — then also install the Gemini Code Assist VSCode Extension.

This lets you:

• chat with Gemini directly inside VSCode
• generate code blocks from the same model
• refactor functions
• debug in context
• create commit-ready PR patches
• and connect directly to Gemini CLI session

Steps to Install inside VSCode

1. Open VSCode → Extensions panel
2. Search for Gemini Code Assist
3. Install
4. Sign-in with same Google account you use for Gemini CLI
5. Make sure GeminiCLI is already authenticated first (this avoids the timeout you saw)

Tip: if you see OfflineError / timeout → close all SSH remote windows → reconnect fresh → then open the Gemini panel again.

Building Your Entire Project Directly from VSCode using Gemini Code Assist

Once the Gemini Code Assist extension is installed in VSCode — you can literally generate full project scaffolding, files, folder structures, APIs, UI components and logic without manually coding everything yourself.

This is where Gemini CLI becomes REAL AI powered software development.

Inside VSCode → just open a blank folder and simply ask Code Assist:

“Create the project files and scaffold the application structure for me”

Gemini will now:

• Create folders
• Create all files (HTML / JS / Python / React / API Handlers etc)
• Setup dependencies
• Configure environment
• Generate complete working code
• Add test logic when required
• And can finally run the local dev server

When Gemini Code Assist proposes the file changes → just press Apply

Gemini writes all code directly into your file system inside VSCode.

Then you simply ask:

“Run the project locally.”

Gemini will start your app from inside VSCode terminal automatically.

This combination of Gemini CLI + Gemini Web UI + Gemini Code Assist inside VSCode gives a complete end-to-end AI powered dev workflow where code is generated, created, edited, debugged and executed completely with AI.

This is the new AI Developer lifecycle.

Gemini CLI UI vs Gemini Code Assist (VSCode)

Gemini Code Assist (VSCode Extension)

• lives inside VSCode
• directly writes files / code / folder structure for you inside editor
• understands your whole project tree
• can apply diffs automatically
• can run build/test commands inside VSCode terminal
• this is basically like AI pair programmer + refactor engine + generator

Gemini CLI

• is a standalone terminal command line interface
• you talk to Gemini in terminal
• prompt mode, tool mode, agent mode
• you can debug, test, create files, run workflows, invoke scripts
• no VSCode dependency
• it is universal (works in any project folder / server / cloud / ssh terminal)

WHY both exist together

Because your web UI part + VSCode coding part + terminal automation part = full AI developer workflow.

Now you can:

This is the NEW AI developer stack.

Conclusion — This is the New AI Native Dev Stack

We are officially entering a phase where “AI Assisted Development” is not a feature anymore — it is becoming the default mode of building software.

• Gemini Code Assist inside VSCode gives you a true AI Pair Programmer
• Gemini CLI gives you autonomous terminal level automation
• Gemini CLI Web UI gives you a visual cockpit to run / inspect / modify
• Each one addresses a different zone of developer flow — and together they unlock a completely new engineering velocity that was not possible before.

This is not about faster code writing. This is about removing friction between thinking → changing → running systems.

If you’re a developer today — this is the moment to start adapting this workflow early.

Because this is how software will be built going forward.
