One single inbox for all your notifications

October 4, 2025 Centralize all your notifications in a single inbox

The Problem Universal Inbox is solving

Let me paint you a familiar picture: It's 9 AM. You already have a dozen notifications in GitHub, a Linear task someone just assigned you, multiple meeting invitations, and a Todoist task list that is already deprecated.

You tab between GitHub, Linear, Slack and many other tools to check their inbox. Each switch breaks your flow. By 10 AM, you've checked five different tools but haven't actually done anything.

Sound familiar?

What I Built

Universal Inbox consolidates all your notifications from multiple tools into a single, unified dashboard. No more tool-hopping. No more missed tasks. Just one place to see everything that needs your attention.

Key Features:

  • 🔗 Unified Dashboard: See GitHub PRs, Linear tasks, Slack messages, Gmail notifications, Google Calendar events, Google Docs comments and Todoist tasks in one view

  • ⚡ Smart Task Conversion - Turn any notification into an actionable task with one click

  • 🔄 Bidirectional Sync - Actions sync back to the original tools (complete a task in Universal Inbox → it updates in Linear/Todoist)

  • 🔄 Tasks synchronization - synchronize assigned Linear issues or Slack saved for later messages with your Todoist task list

Why I Built This

I was drowning in notifications across multiple tools. I tried email consolidation, Zapier workflows, and browser extensions, but nothing worked. So I built Universal Inbox as an open-source solution for digital workers like us who need to stay on top of everything without the mental overhead.

Current Status

  • ✅ Open source: GitHub repo available

  • ✅ 7 integrations live: GitHub, Linear, Slack, Gmail, Google Calendar, Google Drive and Todoist

What's Next

I'm currently in beta and actively looking for feedback from fellow indie hackers. Specifically:

  1. What other tools do you want to be integrated? (Notion, Asana, Jira, Discord?)

  2. What automation workflows would make this 10x more valuable?

  3. Would you pay for this? What pricing feels fair?

About

I have been struggling to check the inboxes of the tools I use daily while keeping my to-do list up to date. Universal Inbox centralises all my notifications in one place, making it easier to manage my to-do list.
