We’re excited to announce the launch of gowebshot v0.1.0, a new command-line tool for capturing webpage screenshots using headless Chrome/Chromium. Released on March 7, 2026, this initial release brings a powerful yet simple solution for automated screenshot capture with both scripting-friendly CLI mode and an interactive terminal UI.

What’s New

gowebshot introduces two distinct ways to capture screenshots:

Non-Interactive CLI Mode — Perfect for automation and scripting. A single command captures your screenshot and exits:

gowebshot --url https://example.com
gowebshot --url https://example.com --preset square

Interactive TUI Mode — Launch without flags to access a keyboard-driven terminal interface with four tabs for configuring URLs, output settings, resolution presets, and capture options like zoom, scroll, and delay.

Resolution Presets

Four optimized presets handle common use cases:

  • widescreen (1920×1080) — Standard desktop captures
  • desktop (1440×900) — Mac and retina displays
  • square (1200×1200) — Social media cards and thumbnails
  • portrait (1080×1350) — Mobile and portrait-oriented content

Custom dimensions are also available via --width and --height flags.

Smart Features

  • Auto-naming protection prevents file overwrites by appending numeric suffixes
  • Chrome auto-discovery locates your installed Chrome/Chromium on Linux, macOS, or Windows
  • Cross-platform binaries ready for immediate use without building from source

Why It Matters

gowebshot fills a gap for developers and operators who need reliable webpage screenshots without the overhead of full browser automation frameworks. The dual-mode design means you can script captures in CI pipelines while still having an interactive tool for ad-hoc exploration.

The release ships with security-conscious defaults: path traversal protection, secure Chrome launch via direct execution, and local CDP communication on ephemeral ports. This makes gowebshot suitable for both local development and automated environments.
