Slack Green is a Slack presence management tool that helps you keep your availability consistent when you need to be reachable. Set your preferred working hours or a custom schedule, and Slack Green will maintain your Slack status as active during those periods—so you don’t appear “away” just because you’re in a long meeting, presenting, or focused on work.

Key features - Scheduled presence: define work hours by day and keep your availability aligned with your routine. - Quick control: pause, resume, or turn it off anytime. - Clearer availability for teams: helps teammates understand when you’re available without manual status changes. - Simple setup: connect it to your Slack workspace and start managing presence in minutes.

Use responsibly and in accordance with your organization’s policies and Slack’s terms.

We've been working on a tool for remote dev teams to automate their agile meetings, here's a demo clip from the estimation poker mode we've been working on! We used nivo, css doodle and react-states on top of tailwind, reactjs, chime sdk and kotlin
