Deterministic Workspace Restoration for Multi-Display macOS.

A native, lightweight engine that captures and restores your complete window layout across monitors in under 20ms. Restores deep browser tabs, IDE split ratios, and adapts to volatile iPad Sidecar UUIDs.

Aftur executes a direct 5-step sandwich geometry sequence (`setSize` → `setPosition` → `setSize` → `setPosition` → `raiseWindow`) to ensure macOS WindowServer commits exact coordinates without race conditions.

Topology Matcher: Tier 1: CoreGraphics EDID Match
Cycle #1 Executed
Under The Hood

Engineered for Multi-Monitor Edge Cases

Other window managers crash or scramble windows when MST hubs or Sidecar disconnect. Here is how Aftur guarantees deterministic execution.

4-Tier Hardware Topology Matcher

Survives MST dock disconnects and HDMI swaps using a 4-tier composite identifier chain: CoreGraphics EDID UUID → Vendor/Model/Serial Composite → Localized Name & Resolution → Aspect Ratio.

Identical MST dual-monitors receive deterministic coordinate-based ordinal suffixes (`-#1`, `-#2`).

Sidecar USB ⇄ WiFi Drift Aliasing

When an iPad switches from wired USB to wireless WiFi, macOS generates a brand new ephemeral display UUID. Aftur correlates virtual display roles and maps windows back to their intended iPad viewport.

Zero window collisions when roaming between desk and meeting rooms.

Browser State & Tab Injection

Restores multi-window tab layouts across Brave, Google Chrome, Arc, Safari, and Microsoft Edge using non-blocking AppleScript automation with zero-stdout purity.

Skips blank start pages, internal container URLs, and restores exact active tabs.

IDE Internal Split Divider Recovery

Traverses the AXUIElement accessibility tree inside VS Code, Cursor, and Xcode to measure and restore vertical and horizontal split-pane ratios (e.g. 60/40 editor/terminal).

Fast-path skips inspection if window frame delta is within 2.0pt tolerance.

750ms Debounced Autonomous Wake

When waking from sleep, macOS sends multiple rapid bursts of screen parameter notifications while DisplayPort negotiates. Aftur coalesces notifications and waits for displays to be online before restoring.

No screen flicker. No window size clamping into tiny 800×600 fallback boxes.

Pure-stdio Model Context Protocol

Includes a native Model Context Protocol (MCP) server over pure stdio. Connect Claude Desktop, Cursor, or AI agent swarms to query displays and manipulate window state programmatically.

Zero logs on stdout to maintain 100% JSON-RPC framing integrity.
Command Line Interface

Built for Terminal Ninjas & Automation

Everything accessible via the menu bar is equally scriptable via the native `aftur` CLI or `aftur://` URL scheme.

Frequently Answered Questions

Technical Details & Guarantees

How does the 14-Active-Day Reverse Trial work?

Unlike calendar trials that tick down while your laptop is closed over the weekend, Aftur counts real active workdays (days where you actually restored or captured a workspace layout). You get 14 distinct days of full Pro access. When the trial expires, Profile #1 remains free forever across up to 2 displays. Your saved profile configurations are never deleted.

Does Aftur work with DisplayLink, MST hubs, and CalDigit docks?

Yes. Aftur was specifically engineered to overcome MST hub issues. When two identical Dell or LG displays share the same vendor and zero serial number over an MST daisy chain, Aftur sorts them deterministically by coordinate origins and assigns stable ordinal suffixes (`-#1`, `-#2`) so your IDE and terminal windows never swap screens on sleep wake.

Can I run Aftur completely air-gapped without internet access?

100% yes. Aftur’s licensing engine embeds the studio Ed25519 public key in the binary. When you activate your license, the digital signature and your Mac’s hardware UUID hash are verified completely on-device using CryptoKit. Once verified, the signed receipt is cached in your macOS Keychain (`kSecAttrAccessibleAfterFirstUnlockThisDeviceOnly`). You can take your Mac to an air-gapped SCIF or mountain cabin and it will run forever.

What permissions does Aftur require on macOS?

Aftur requires macOS Accessibility permissions (`AXUIElement`) to inspect window bounds and set frames, and optional Automation permissions (`AppleScript`) if you wish to restore browser tabs in Brave, Chrome, Safari, or Arc. Aftur does not run kernel extensions, does not require root permissions, and includes an automated 1-click repair if macOS ad-hoc TCC code-signing drifts.
