    Dock – Slack minus the bloat, tax, and 90-day memory loss▲177

    Hey HN – I built Dock after years of team chat frustrations as a founder. Free forever for teams up to 5. Unlimited search, unlimited history.

Early stage – would love feedback from anyone who's felt the same pain.

    Hi HN! I'm Kam, the founder and one of the authors of Linen. Today, we are launching Linen.team (https://linen.team/), a lightweight threaded messaging app for your team. Modern workplace messaging apps (like Slack) are based on IRC, which is great for small groups, but as it scales, breaks down quickly: you either get overwhelmed by notifications or you have to turn them all off.
