Launch week: every idea card is free.Get Pro

SaaS ideas, mined from what people actually complain about.

Every idea comes from real Reddit posts, was researched against today's competitors, and survived an independent skeptic before it made the list.

Unreliable File Sync

Users across many apps and platforms cannot trust file sync to work silently, reliably, or transparently, leading to lost data, duplicates, and manual recovery.

In their words

Every time the markdown sync hiccups I lose an evening to it.

r/selfhosted on Reddit

Syncovery receives no information for many of those same remote files, with remote size and date fields completely blank as if it’s a brand new upload.

r/Drime on Reddit

one browser reset, cleared site data or dead laptop and the whole prep is gone unless I remembered to export a JSON backup

r/cinematography on Reddit

the nextcloud app does not let me do proper two way sync between my android tablet and my server is a massive pain point

r/NextCloud on Reddit

the best balance was a custom list based on location and team, plus a small companywide list of important numbers like IT Support or HR

r/microsoft365 on Reddit

the app on the phone and on my laptop do not sync even tho sync status is shown as linked

r/macapps on Reddit

Is there a way to be alerted if Onedrive has no activity for more than x number of hours/days.

r/sysadmin on Reddit

Every day, multiple users have one issue or another with the OneDrive sync client.

r/sysadmin on Reddit

a foreman editing a task title against a stale copy would silently revert the worker's status change made minutes earlier

r/FlutterDev on Reddit

it went from fully professional daily use to the single biggest problem with my main work tool

r/NextCloud on Reddit

The CLI rebuilds its entire file index from scratch in memory on every startup, with no persistent state between runs.

r/filen_io on Reddit

Is there a tool out there with a lightweight client that just does file copying or something?

r/Intune on Reddit

early attempts at syncing didn't work well. I paid to support the sync effort but we saw nothing for years.

Hacker News

my current experience is just getting error messages on my phone every week that something failed to sync, and that I have to re-enter the app every ~month to disable/enable syncing for my offline files, otherwise it doesn't work.

Why those fall short

  • No built-in alerting for silent sync stop; status invisible until breakage
  • clients fall over at scale, no command line switches, resync everything
  • sync hiccups cost an evening; self-hosted services need patching and worry
  • clocks drift; NTP needs IT; standalone sites lack network; JACE time resets after outages
  • Models went down wrong path for weeks; stale SSOT docs; solution not performant
