HotBot vs PullNotifier: PR notifications for Slack, compared honestly
PullNotifier sends rich per-PR notifications to Slack and Teams, with Slack user mapping and a free plan - it is a solid Slack-only tool. Its live message updates on approvals and comments, but CI pipeline results are not part of that update loop. HotBot covers Slack and Discord, is digest-first (one filtered daily message), pushes CI results into both the digest and the live PR status via webhooks, and adds escalation rules. Pick PullNotifier for Slack-only per-PR review chatter; pick HotBot for quiet channels, Discord, and CI status that actually reaches the team.

Why teams pick HotBot over PullNotifier
HotBot replaces the flood of per-event notifications with one daily digest. Drafts, WIP, and bot PRs don't show up. Your team sees only what needs reviewing, with CI status and reviewer assignments, all in one message.
HotBot also has a live-updating PR status board that stays current without any manual refreshing, and escalation rules so stale PRs don't sit forever.
