Show HN: VacayBuddy – PTO Management Inside Slack (Open Source)

I built VacayBuddy, an open-source Slack bot that makes managing Paid Time Off (PTO) simple and seamless — all from within Slack.

Features: • Request and track PTO directly from the Slack app home • Get notified and approve PTO via Slack modals • Admin dashboard to manage team PTO balances and history • Excel integration for migrating existing PTO data • Works out of the box with SQLite for local setup

We use it internally to manage our team’s PTO without emails or spreadsheets. Would love your feedback or contributions!
