Show HN: Slack bot for channel-owned mention aliases (not org-wide user groups)
yippa.ioTeams in Slack often end up pasting long @mention chains, and someone gets missed (or the wrong person gets pinged). It’s worse for rotating groups like on-call, releases, incident response.
We built Alias Bot: each channel can define aliases like `!oncall` / `!reviewers`. When someone uses an alias, the bot replies with the expanded mentions and lists exactly who was notified (so there are no hidden pings).
This is intentionally channel-scoped (vs Slack user groups being workspace-wide), so the same alias can mean different things in different channels without admin overhead.
Privacy note: the backend stores alias configuration (alias → member IDs per channel), processes message text to detect alias usage, and does not store or log message bodies ever.
Free plan includes up to 3 aliases; pricing is flat. You purchase number of aliases you could create and is not seat-based (user-based).
Would appreciate feedback from EMs/TLs/SREs: is this a real pain for your teams, and what would block adoption (noise, permissions, governance, drift)?
