Team chat that stays out of your way.

Everything new lands in one stack. Read it, answer it, clear it, and get back to work.

The demo is a real team, private to you. No signup, and it vanishes in a day.

Dry run went fine, except checkout still shows the old box photo.

@You we can roast 40 kg more than planned. Yes or no by end of day?

Six places to check, or one.

Most team chat grew a Home tab, an Activity tab, a Threads view, a Later view, a Mentions view and a pile of bold channel names. So people make rituals to get through it all. In Stack, the ritual is the product.

  1. Open it. What's aimed at you is on top. Then people talking. Then bots.
  2. Answer right there. Each card has its own reply box. You don't have to go anywhere.
  3. Press E. The next card comes up. Change your mind? Undo.
  4. You're clear. Nothing's waiting. Close the tab.

Replies stay where they happened.

No side panel to lose track of. A thread opens right under its message, and every reply also leaves one line in the channel. Nothing gets lost in a place you weren't looking.

Quiet by default. Reachable when it matters.

You're pinged for direct messages, mentions and threads you're in, and that's it. Outside your hours nothing buzzes. People messaging you can see when you're back, and if it really can't wait, they can say so.

One bar

Ctrl+K finds a person, a channel or anything anyone ever said, as you type. It also starts new conversations. There's no second search to learn.

All your history, always

Old messages don't disappear after 90 days. What your team wrote stays yours and stays searchable.

Bots know their place

Bot messages look quieter and sort last. The deploy notifications are there when you want them, and they don't compete with your colleagues.

Small and quick

A little Rust server and a page with no framework. The whole app is about 60 KB to download, and switching conversations is instant.

Coming from Slack? Bring it all.

Upload your Slack export. Channels, threads, reactions, people and files come across, and none of it lands on anyone's stack. Your Slack webhooks work with just a new URL.

And when you want to leave, it's one click: everything in Slack's own export format, with your files. No call with sales.

What we left out

Canvases. Lists. A workflow builder. An app directory. Clips. Slash commands. Keyword alerts. Sidebar folders. We asked "is this truly needed?" and kept asking. If your team lives in those, Slack is very good at them. If your team just needs to talk, you're in the right place.

See how it feels.
