    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. No "upgrade to see messages older than 90 days" nonsense. Built for teams who work both async and sync/real-time when it matters. runs on SOC 2 infra, compliant, secure and in-transit and at-rest encryption, runs on Cloudflare. Early stage – would love feedback from anyone who's felt the same pain.
