A dev turned Gmail into a scrollable feed where emails auto-expire

A solo developer rebuilt their Gmail inbox to look and feel like an Instagram feed, with emails automatically disappearing after a set time. It's aimed at people drowning in newsletter subscriptions.

The project sits on top of Gmail and transforms incoming emails into a visual card-based feed you can scroll through quickly, similar to how Instagram shows posts. Instead of a cluttered inbox, each email appears as a card with an image and title. A key feature is auto-expiry: emails delete themselves after a chosen period, keeping the inbox clean without manual effort. This is a classic solo-builder move — identify a personal pain point (newsletter overload), build a lightweight tool to fix it, and post it to r/SideProject to gather early feedback and potential users.

Key points

  • Emails display as visual cards in a scrollable feed

  • Shared on r/SideProject to get early real-world feedback
