Captain Spyglass — Alignment Inspector

Reveal element alignment with edge guides, a center cross and a transparent page grid — then screenshot the page with the overlay.

Spyglass is a lightweight visual alignment and screenshot tool for web pages. Turn it on to reveal how elements line up, then capture and mark up exactly what you see — without a single byte leaving your device. WHAT IT DOES • Alignment overlay — a transparent column grid, edge guides, and a center cross drawn over the live page, so you can see spacing and alignment at a glance. • Hover to inspect — move your cursor over any element and Spyglass highlights its exact edges and center lines. • One-key toggle — press Alt+Shift+A (or click the toolbar icon) to switch the inspector on or off on the current tab. • Screenshot with the overlay — hold ⌘ (Mac) or Ctrl (Windows/Linux) and click anywhere to capture the visible page, overlay and all, into your local history. • Capture history + editor — browse your captures, rename them, and edit each one with simple tools (crop, highlighter, pen, rectangle), then download the PNG. PRIVACY-FIRST BY DESIGN Spyglass does everything on your machine. No sign-in, no account, no analytics, no server. Your screenshots and settings are stored locally in your browser and are never uploaded or shared. It requests no broad website access — it only acts on the tab you point it at. WHO IT'S FOR Designers, front-end developers, QA engineers, and anyone who needs to check spacing and alignment on a live page or grab a quick, marked-up screenshot. Spyglass is part of the Pirates of Bugs toolkit.
