• Download files - Download individual files or entire prefixes
• Sync folders - Sync S3 prefixes to local directories (only downloads changed files)
• Bookmarks - Save frequently accessed locations
• Demo mode - Try the UI without AWS credentials

Prerequisites

• AWS CLI v2 - Required for SSO authentication
  • Installation instructions
  • Verify installation: aws --version

Installation

Quick Install (macOS/Linux)

curl -fsSL https://stui.app/install.sh | bash

From Binary

Download the latest release for your platform from the Releases page.

# macOS/Linux - make executable and move to PATH
chmod +x stui-*
sudo mv stui-* /usr/local/bin/stui

# Or without sudo, add to your local bin
mkdir -p ~/.local/bin
mv stui-* ~/.local/bin/stui
# Add to PATH in ~/.zshrc or ~/.bashrc: export PATH="$HOME/.local/bin:$PATH"

From Source (requires Go)

go install github.com/natevick/stui/cmd/stui@latest

This installs to $GOPATH/bin (usually ~/go/bin), which should be in your PATH.

Or clone and build:

git clone https://github.com/natevick/stui.git
cd stui
go build -o stui ./cmd/stui

AWS SSO Login

Before using with SSO profiles, authenticate with the AWS CLI:

aws sso login --profile my-profile

This opens a browser window to complete authentication. Once logged in, you can use stui.

Usage

# Launch with profile picker
stui

# Launch with specific profile
stui --profile my-profile

# Launch directly into a bucket
stui --profile my-profile --bucket my-bucket

# Demo mode (no AWS credentials needed)
stui --demo
