Spice up your day-to-day productivity with some free Thyme, courtesy of the team at Sourcegraph (the best way to read and explore code). Automatically track which applications you use and for how long.

  • Simple CLI to track and analyze your application usage
  • Detailed charts that let you profile how you spend your time
  • Stores data locally, giving you full control and privacy
  • Open-source, well-documented, and easily extensible

Thyme is a work in progress, so please report bugs! Want to see how it works? Dive into the source here.

Simple CLI
  1. Record which applications you use every 30 seconds:

    $ while true; do thyme track -o thyme.json; sleep 30s; done;
  2. Create charts showing application usage over time. In a new window:

    $ thyme show -i thyme.json -w stats > thyme.html
  3. Open thyme.html in your browser of choice to see the charts below.

Thyme's dependencies vary by system. See thyme dep (mentioned in the installation instructions below).


  1. Install Go (if you have Homebrew on macOS, you can also run brew install go) and run

    $ go get -u

    Alternatively, if you don't want to install Go, just download the thyme binary here.

  2. Follow the instructions printed by thyme dep.

    $ thyme dep
  3. Verify thyme works with

    $ thyme track

    This should display JSON describing which applications are currently active, visible, and present on your system.

Thyme currently supports Linux, macOS, and Windows.

Usage for Other Shells

Windows Powershell
> for(1){thyme track -o thyme.json; Start-Sleep -s 5}
> thyme show -i thyme.json -w stats | Out-File -e utf8 thyme.html
Windows DOS Command Line
> for /L %n in (0) do @(thyme track -o thyme.json && timeout /t 5 /nobreak)
> thyme show -i thyme.json -w stats > thyme.html

Use cases

Thyme was designed for developers who want to investigate their application usage to make decisions that boost their day-to-day productivity.

It can also be for other purposes such as:

  • Tracking billable hours and constructing timesheets
  • Studying application usage behavior in a given population

How is Thyme different from other time trackers?

There are many time tracking products and services on the market. Thyme differs from available offerings in the following ways:

  • Thyme does not intend to be a fully featured time management product or service. Thyme adopts the Unix philosophy of a command-line tool that does one thing well and plays nicely with other command-line tools.

  • Thyme does not require you to manually signal when you start or stop an activity. It automatically records which applications you use.

  • Thyme is open source and free of charge.

  • Thyme does not send data over the network. It stores the data it collects on local disk. It's up to you whether you want to share it or not.

                      DarwinTracker tracks application usage using the "System Events" API in AppleScript. Due to the liminations of this API, the DarwinTracker will not be able to detect individual windows of applications that are not scriptable (in the AppleScript sense). For these applications, a single window is emitted with the name set to the application process name and the ID set to the process ID.

                            func (s Snapshot) Print() string

                              Print returns a pretty-printed representation of the snapshot.

                              type Stream

                                  	Rows  map[string][]*Range

                                    Timeline represents a timeline of application usage. Start is the start time of the timeline. End is the end time of the timeline. Rows is a map where the keys are tags and the values are lists of time ranges. Each row is a distinct sub-timeline.

                                      NewTimeline returns a new Timeline created from the specified Stream. labelFunc is used to determine the ID string to be used for a given Window. If you're tracking events by app, this ID should reflect the identity of the window's application. If you're tracking events by window name, the ID should be the window name.

                                      type Tracker

                                      type Tracker interface {
                                      	// Snap returns a Snapshot reflecting the currently in-use windows
                                      	// at the current time.
                                      	Snap() (*Snapshot, error)
                                      	// Deps returns a string listing the dependencies that still need
                                      	// to be installed with instructions for how to install them.
                                      	Deps() string

                                        Tracker tracks application usage. An implementation that satisfies this interface is required for each OS windowing system Thyme supports.

                                          NewTracker returns a new Tracker instance whose type is `name`.

                                          type Window

                                          type Window struct {
                                          	// ID is the numerical identifier of the window.
                                          	ID int64
                                          	// Desktop is the numerical identifier of the desktop the
                                          	// window belongs to.  Equal to -1 if the window is sticky.
                                          	Desktop int64
                                          	// Name is the display name of the window (typically what the
                                          	// windowing system shows in the top bar of the window).
                                          	Name string

                                            Window represents an application window.

                                            func (*Window) Info

                                            func (w *Window) Info() *Winfo

                                              Info returns more structured metadata about a window. The metadata is extracted using heuristics.


                                              1) Most windows use " - " to separate their window names from their content
                                              2) Most windows use the " - " with the application name at the end.
                                              3) The few programs that reverse this convention only reverse it.

                                              func (*Window) IsOnDesktop

                                              func (w *Window) IsOnDesktop(desktop int64) bool

                                                IsOnDesktop returns true if the window is present on the specified desktop

                                                func (*Window) IsSticky

                                                func (w *Window) IsSticky() bool

                                                  IsSticky returns true if the window is a sticky window (i.e. present on all desktops)

                                                  func (*Window) IsSystem

                                                  func (w *Window) IsSystem() bool

                                                    IsSystem returns true if the window is a system window (like "unity-panel" and thus shouldn't be considered an application visible to the end-users)

                                                    type Winfo

                                                    type Winfo struct {
                                                    	// App is the application that controls the window.
                                                    	App string
                                                    	// SubApp is the sub-application that controls the window. An
                                                    	// example is a web app (e.g., Sourcegraph) that runs
                                                    	// inside a Chrome tab. In this case, the App field would be
                                                    	// "Google Chrome" and the SubApp field would be "Sourcegraph".
                                                    	SubApp string
                                                    	// Title is the title of the window after the App and SubApp name
                                                    	// have been stripped.
                                                    	Title string

                                                      Winfo is structured metadata info about a window.

                                                      func (w Winfo) Print() string

                                                        Print returns a pretty-printed representation of the snapshot.
