Show HN: Later – Schedule URLs to open later

1 point

5 months ago

I built Later to scratch my own itch: I'd find interesting articles but not have time to read them, or I'd forget to join meetings because I was deep in code.

Later is a browser extension + local daemon that lets you schedule any webpage to open at a specific time. Press Option+L, pick a time (or use presets like "In 1hr" or "Tonight"), and the page opens automatically – even if your browser is closed or you're in another app.

Technical details: - Browser extension (Firefox + Chrome) for the UI - Python daemon (FastAPI + SQLite) handles scheduling and opens URLs via the system - launchd integration for auto-start on macOS - Everything runs locally, no accounts or cloud

The daemon approach was intentional – it steals focus when the time comes, which is what you want for meetings. A pure extension would open tabs silently in the background.

Built on a lazy Christmas afternoon with Claude Code. Happy to answer questions about the architecture or implementation.
