Privacy First — By Design, Not by Policy

A7Box is 100% local. Every tool — JSON formatting, screenshot capture, hash generation, file compression — runs entirely on your machine. No data ever leaves your computer. No network requests. No telemetry. No account required.

Zero Network Requests Zero Telemetry Zero Account Required Open Source & Auditable

"In an era where every app wants your data, A7Box respects a simple principle: your tools should work for you, not against you."

Built Different

Every feature is designed with one goal: maximum output with minimum overhead.

Cross-Platform

Native support for Windows, macOS, and Linux from a single Tauri 2 codebase. One app, three platforms.

100% Local & Offline

All processing on your machine. No internet required. No data ever leaves. Works in airplane mode.

Featherweight ~10MB

Tauri + Rust backend — not Electron. ~10MB installer, minimal memory footprint, instant startup.

Spotlight Command Palette

Fuzzy search, category filtering, keyboard navigation. Hit Ctrl+K — any tool, milliseconds away.

Clipboard Quick Actions

Copy content, press a shortcut, floating window pops up to process — JSON, code, Markdown, QR.

Full Screenshot Workflow

Capture → annotate (pen/rect/text/mosaic/blur) → pin to screen → session history. All in one flow.

Pixel-Level Color Picker

Full-screen transparent overlay with real-time magnifier for precise pixel-level color sampling.

LAN Collaboration

Serve any directory as a website over LAN. P2P transfer files with other A7Box devices on the same network.

Highly Customizable

Custom shortcuts, drag-to-reorder modules, dark/light/system theme, i18n (English / Chinese).

18 Tools, One Box

Accessible via sidebar, command palette (Ctrl+K), or global shortcuts.

Engineering, Not Armament

The name A7 is deliberate. Take one of the most iconic engineering symbols in history — the AK-47. Extract its first letter A and its last digit 7. You get A7.

Not for what it represents as a weapon, but for what it stands for as engineering: reliability, simplicity, and efficiency. Maximum output with minimum overhead.

The "Box" completes the picture: one container, a full arsenal of tools. From JSON formatting to screenshots, from file compression to LAN transfer — everything a developer reaches for daily, unified in a single ~10MB application.

That's why our slogan reads: Your Tactical Efficiency Weapon on Desktop.
