Your Dock tells the story of the tools you live in. Dock Timelapse records it quietly every day and turns its evolution into an Apple-style timelapse: apps springing in, others handing over their spot, a day counter ticking, all drawn over your own wallpaper.

How it works

Records — an hourly background agent reads the Dock's own preferences (the pinned apps, up to and including System Settings). On each day the Dock changes it saves a snapshot: the app list, every icon in high resolution, and the current wallpaper. Optionally it keeps a cropped Dock screenshot too.
Renders — the videos are redrawn from that data: a glass Dock over your blurred wallpaper, spring animations, change labels (+ Linear, Cursor replaces Xcode), the date and day counter, and a progress bar scaled to real calendar time.
Previews on day one — preview invents a plausible past that ends with your real Dock, so you can see your video right away.

Requirements: macOS and uv. ffmpeg comes bundled.

Install

Command line

uv tool install git+https://github.com/bcldvd/dock-timelapse

dock-timelapse install        # start recording (hourly agent, one snapshot per day of change)
dock-timelapse preview        # see your video now, with an invented past
dock-timelapse render         # later: the real timelapse → ~/Movies/Dock Timelapse/

Claude Code

/plugin marketplace add bcldvd/dock-timelapse
/plugin install dock-timelapse@dock-timelapse

The plugin brings the skill and the MCP server. Then just ask: "start recording my Dock", "make a timelapse of my Dock", "which apps did I add since June?"

Codex, Cursor, Gemini CLI, Copilot and other agents

The skill follows the open Agent Skills format:

MCP server (Claude Desktop, Codex, Cursor, VS Code, …)

{
  "mcpServers": {
    "dock-timelapse": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/bcldvd/dock-timelapse", "dock-timelapse", "mcp"]
    }

Tools: dock_status, current_dock, dock_history, install_recording, uninstall_recording, capture_now, render_timelapse, render_preview.

Usage

dock-timelapse status                                     # recording state + every snapshot and its changes
dock-timelapse render --format portrait                   # landscape | portrait | both (default)
dock-timelapse render --background white                  # wallpaper (default) | desktop (sharp) | white
dock-timelapse preview --demo                             # a generic demo Dock
dock-timelapse still --t 2 5.5                            # single PNG frames
dock-timelapse install --screenshots                      # also keep Dock screenshots
dock-timelapse uninstall                                  # stop recording, history stays

Screenshots use the Screen Recording permission: install --screenshots prints the Python path to add in System Settings → Privacy & Security → Screen & System Audio Recording. The videos only need the Dock data, so this step is optional.

Data lives in ~/Library/Application Support/dock-timelapse/ (snapshots.json, icons, wallpapers, and capture.log).

Development

module	role
`dockdata.py`	parse Dock prefs → ordered apps, up to System Settings
`diff.py`	added / removed / replaced / moved between two Docks
`store.py`	snapshots on disk, one per day of change
`capture.py` · `visibility.py` · `macos.py`	one capture attempt; Dock visibility; the macOS calls
`agent.py`	the launchd agent
`timeline.py` · `layout.py`	pure animation model and geometry
`render.py` · `video.py`	Pillow frames → ffmpeg H.264
