anchr

A fast terminal UI for browsing S3 and S3-compatible object storage.

Features

• Browse multiple buckets from a single config
• Works with AWS S3 and S3-compatible stores (MinIO, Supabase, …)
• Keyboard-driven two-pane navigation (bucket sidebar + object browser)
• Download files straight from a bucket
• Optional prefix filtering to start inside a folder
• Single static binary, no dependencies

Install

Recommended — install the latest release with one command:

curl -fsSL https://anchr.jackjakarta.guru/install.sh | bash

Builds are available for Linux and macOS (amd64 and arm64). The script verifies checksums and installs to /usr/local/bin (or ~/.local/bin). Useful environment variables:

• ANCHR_VERSION — install a specific version (e.g. v0.1.0), default: latest
• ANCHR_INSTALL_DIR — install to a custom directory

From source:

go install github.com/jackjakarta/anchr@latest

Configuration

anchr reads ~/.config/anchr/config.yaml (override with --config or XDG_CONFIG_HOME). Define one or more buckets:

buckets:
  # AWS S3 — uses the default credential chain (~/.aws/credentials, env, IAM)
  - name: "Production"
    bucket: "my-production-bucket"
    region: "us-east-1"

  # S3-compatible storage (MinIO, Supabase, …)
  - name: "MinIO"
    bucket: "dev-bucket"
    endpoint: "https://minio.internal:9000"
    region: "us-east-1"
    access_key: "..."
    secret_key: "..."
    path_style: true
    prefix: "images/" # optional starting folder
