sleek vs Taskwarrior

sleek

• People who keep their tasks in a plain todo.txt file
• Using one task file from several todo.txt apps
• Desktop users who want a free graphical todo.txt app
• Keyboard users: the app is navigable with shortcuts

Taskwarrior

• People who work in a terminal and want to manage tasks by typing
• Keeping task data in a local database, with sync as an option
• Scripting a personal workflow with hooks and custom fields

sleek

• Desktop only: sleek is offered for Windows, macOS and Linux, with no mobile or web version.
• Tasks live in todo.txt files, and the README and wiki describe no built-in sync service, so sharing a file between devices is left to other tools.
• The Flatpak build runs in a sandbox and needs extra file permissions before it can reopen a todo.txt file after a restart.
• The README says the backlog is growing while capacity is limited, and asks for contributors and sponsors.

Taskwarrior

• The project ships only a command-line program. Graphical, web and mobile front ends are separate community tools.
• On Windows it runs through the Windows Subsystem for Linux or MSYS2; Cygwin is no longer supported.
• No hosted sync service is included: you run a TaskChampion sync server or configure a cloud storage bucket yourself.
• Since version 3.0 the docs warn that file-sync tools such as Syncthing or rsync can corrupt task data and are unsupported.

Works on todo.txt files

sleek opens existing todo.txt files or creates new ones and can manage several at once. A file watcher picks up changes made to a file by other todo.txt apps.

todo.txt attributes with pickers

Todos carry priorities, contexts, projects, due dates, recurrence, threshold dates for deferred todos and pomodoro intervals, set by typing the syntax or through built-in pickers.

Filter, sort, group and search

Todos can be filtered, sorted and grouped by any attribute, with the order of each group invertible, and an advanced search accepts filter expressions based on todo.txt syntax.

Recurring todos and notifications

Marking a recurring todo complete creates the next one, and due dates can trigger notifications.

Archiving completed todos

Completed todos can be shown, hidden or archived into a separate done.txt file.

Markdown and human-friendly dates

Descriptions support Markdown, including links with custom protocols such as file://. Due and threshold dates can be typed as spoken dates, and todos can be created multi-line or in bulk.

Taskwarrior

Task commands in the terminal

Tasks are added, modified and completed with short task commands, and carry attributes such as project, tags, priority and due date out of more than 20 standard ones.

Filters, reports and contexts

Reports list tasks through filters you combine on the command line. A context is a named filter that stays active, for example to show only work tasks.

Urgency score

Each task gets a numeric urgency score summed from a dozen or more factors such as priority, and the next report sorts tasks by it.

Sync between replicas

The task sync command exchanges changes with a TaskChampion sync server, an AWS or Google Cloud storage bucket, a local file or a git repository.

Hooks and user defined attributes

Hook scripts in any language run at set events in the program, and user defined attributes add your own fields that can be stored, sorted and shown in reports.

JSON import and export

Task data moves in and out through a documented JSON format, which the community tools listed on the project's Tools page build on.

sleek

• Free$0

  The complete app from the Mac App Store, Microsoft Store, Snap Store, Flathub, Homebrew, the AUR or a direct download.

Taskwarrior

• Free$0

  The full command-line program under the MIT license. Sync needs your own server or a cloud storage bucket, which the docs say carries a small cost.
