Plan on a board.
Sync to GitHub*.

A live, multiplayer whiteboard full of your real issues and pull requests. Plan together on a call or across time zones, and what you decide goes back to GitHub as new issues, labels and milestones.

Or GitLab, Codeberg or Tangled.

A Tack board: live issue and pull request cards with labels, CI and reviews, a stack of stickies and an issue with a suggested name, stickies from a planning session, a live list of open bugs and a milestone's progress, with three teammates' cursors on it, one saying “+1, docs first”.A Tack board: live issue and pull request cards with labels, CI and reviews, a stack of stickies and an issue with a suggested name, stickies from a planning session, a live list of open bugs and a milestone's progress, with three teammates' cursors on it, one saying “+1, docs first”.

For teams who plan together

Maintainers and contributors planning releases, roadmaps, triage and retros, on a call or across time zones over a week. Public boards for planning in the open, private ones for everything else. The board is where you think; GitHub is where it lands.

Write back

Decide on the board, then push it to GitHub

Stickies become issues, a section a parent issue with sub-issues, an arrow a blocked-by link, a decision an ADR pull request; labels, milestones and assignees too. It all waits in one list until someone reviews it and pushes, as themselves or as the app's bot.

How writing back works
The push sheet: new issues with their bodies and labels, a pull request, how many watchers will be notified, and a choice of pushing as yourself or as Tack's bot.The push sheet: new issues with their bodies and labels, a pull request, how many watchers will be notified, and a choice of pushing as yourself or as Tack's bot.

Stacks and AI

From a wall of stickies to a few themes

Select a whole wall of stickies, issues and pull requests, and Auto-stack sorts them into themes for you, each stack named from what's in it. Or drag one sticky onto another to stack them yourself, like apps in a folder on your phone. The AI runs on your own Cloudflare account, and every suggestion is yours to keep, rename or undo.

Stacks
A planning board: stickies about what to fix in unpic 5.0, and three stacks beside them, each a card with its name, how many it holds and its first few stickies and issues.A planning board: stickies about what to fix in unpic 5.0, and three stacks beside them, each a card with its name, how many it holds and its first few stickies and issues.

Facilitation

Live, or across time zones

Start from a template for a planning session, a retro or triage, with each step ready to run. On a call, there's a shared timer, spotlight, silent writing and stamps. Off it, dot votes stay open for days, comments thread, “since you were here” catches people up, and a weekly digest goes out as a GitHub Discussion or by email.

Widgets and automation

Boards that keep themselves current

Live lists, a timeline, a release draft, a dependency map with its critical path, a review queue, milestone progress and a stale finder, or a widget of your own, sandboxed. Inbox sections collect new matches for a search, and rules place pull requests beside the issues they fix.

The widgets
A timeline of issues opened over a month, a release draft sorted into features, fixes and docs, and a dependency map flagging a cycle and the critical path.A timeline of issues opened over a month, a release draft sorted into features, fixes and docs, and a dependency map flagging a cycle and the critical path.

Phones and tablets

Join in from your phone

Tap anything on a board to read it, vote, stamp and comment, and add stickies from the +. On a tablet, edit with a finger or a pencil.

Open source, and yours to run

Tack is MIT licensed, and every instance is someone's own: the boards, and everything on them, stay in your Cloudflare account. Most of it runs on Workers' free plan.

  • One Worker, on your account

    Each instance is a Cloudflare Worker and a GitHub App you own, set up in about fifteen minutes. There's no hosted Tack and no account to make with us.

    Get your own

  • GitHub decides who sees what

    Everyone signs in with GitHub. A card from a private repository only shows its details to people who can read it there, and pushes go out with each person's own permissions.

    Who sees what

  • Not only GitHub

    Issues and merge requests from GitLab, Codeberg, other Forgejo instances and Tangled sit beside GitHub's, live where the instance gets their webhooks.
