A developer’s workday in one window: your tasks from 13 trackers, today’s meetings and your notes, from the keyboard.
Free and open source No account Your data in one file on your disk
Tracker, calendar, mail, notes, chat — each with its own notifications and its own counters.
Tasks from your trackers and meetings from your calendar, gathered into one feed for the day. What’s urgent stands out in colour.
Try it
Date, time, label and priority are picked up on their own. Then clear the list — with the d key or a click on the circle.
A day with Tabless
Meetings and tasks for the day in one feed. What’s on now and what’s due today stand out at once.
A calendar week and your tasks in one view. Drag a task onto a time slot — it’s scheduled.
Ctrl Shift Space from any app, even with Tabless minimized: “fix login tomorrow 15:00”. The date is read from the words. For a note — Ctrl Shift N.
Properties on top, text and checklist below. It saves itself. Done is one key: D.
The failed-attempt counter resets when the email changes case — User@x.io and user@x.io count as different keys.
key := "login:" + strings.ToLower(email)
if limiter.Allow(key) == false { return ErrTooMany }
Write right here. / — insert a checklist, code, a task link.
Notes and docs in one section. #APP-112 in a note becomes a link with the task’s title.
The limiter counts attempts by the key login:<email>. Bug in
APP-101
— the key is not normalized.
429 with a Retry-After, as in RFC 6585. The body gives no hint whether the account exists.
Git
Add your repositories in Settings → Git. The branch is read from .git/HEAD: when its name carries a task id like APP-112, that task shows at the top of the window, and the PR state comes from your own gh or glab. No bindings, no plugins.
$ Switched to branch 'APP-112-flaky-sync-test'
On a branch switch the task moves to In Progress by itself. That can be turned off in Settings → Git.
Keyboard
Keys as in Vim: j and k through lists, d for done, g to go, y to copy. They follow the physical key, so they work in any keyboard layout, and any shortcut can be rebound. Press one.
Single letters act on the task under the cursor and only while you aren’t typing; Ctrl shortcuts work everywhere. On this site: Ctrl K or / searches, g g goes to the top.
Style
The bold style: fills, counters, colour for what’s urgent and key hints on screen. Quiet takes all that away: outlines instead of fills, colour only where it means something. Switch in Settings, no restart. Drag the divider.
How it’s built
Qt 6 · C++20
No browser inside. The Linux AppImage carries its own Qt, nothing else to install.
0 services
Runs while its window or tray icon is open. Starting at login only if you turn it on.

Source, build and change history are on GitHub.

Your data
Tasks, meetings and notes live in one file, state.json. The network is used only for the update check and for what you connect yourself.
Download, open, work. No account, no email.
By default nothing is written to your trackers. Status write-back is turned on per tracker: “Change the status in Jira when I move a card”. Before every write the task is checked again; if the tracker changed it meanwhile, nothing is sent. Titles, descriptions and comments are never written.
Scheduled backups (daily by default, the last 20 kept) and a time machine: hourly snapshots for two days, daily ones for a month.
Next to the file: a backups folder with the scheduled copies and a history folder with the time machine’s snapshots.
Tracker tokens are not in state.json. On Windows they go to the system credential store; the macOS and Linux builds keep them in a secrets.json next to it that only your user can read.
Notes export as a folder of Markdown files that Obsidian opens as-is, and import back from one.

}Cards from a tracker also carry a local layer: your own notes, checklist, tags and dates. A sync never overwrites it.
The complete list. If it isn’t here, Tabless doesn’t send it. No analytics. After a crash the app offers a report: you see all of it, choose what goes in, and send it yourself as a GitHub issue. The app never sends it on its own.
Asks GitHub whether a newer version exists. Sends nothing about you or your data. Downloads the update only when you click Update, and checks it against the release’s checksums.
Pull your tasks — by hand, or on a timer if you set one. A status is written back only where you turned write-back on.
Your browser opens the tracker’s own sign-in page; Tabless never sees your password.
Downloads the .ics file at the link you added, every 15 minutes by default.
Runs your own gh or glab about once a minute. Off in Settings → Git.
Reads the people in your channels to offer them as @mentions. Posts nothing.
Images from the web in a note load when you ask to show them.
Browser sign-in: GitHub, GitLab, Sentry, Jira, Trello, Todoist, Asana, ClickUp, Bitbucket. Gitea and Forgejo: a token, or browser sign-in through your own OAuth app. Redmine: an API key. Mattermost: a token or your login; the password itself is not stored.
FAQ
Yes. Open source under the MIT license, with no paid tier, no trial and no account.
Completely. Your data is a file on your disk. The network is needed only for the update check and for the trackers and calendars you connect yourself.
Yes, by moving the data: export the profile to JSON and import it on the other machine — importing only adds and never overwrites a profile. Or copy state.json while the app is closed.
No, it’s a personal workspace. Shared work stays in your team’s tracker: issues are pulled in, and by default nothing is written back. Status write-back is turned on per tracker; it exists for GitHub, GitLab, Gitea, Forgejo and Jira.
Yes. Notes import from a folder of .md files (you see what comes in first) and export to a new folder. [[wiki-links]] stay as they are; the .obsidian folder is skipped.
