What’s one online tool that frustrates you the most with paywalls or daily limits?

Every time I need to quickly convert a PDF to Excel, stitch images together, or compress a video for an email, I feel like I get hit with a 'You’ve reached your 2 free tasks for today. Upgrade to Pro for $12/month' wall, or a 15-second timer.

It got so frustrating that I built an open, 100% in-browser suite (iLoveTools) where files never get uploaded to a cloud server and there are zero paywalls.

Curious for other makers and remote workers: What everyday online utilities do you find most annoying to pay a subscription for? What tools are currently missing from your workflow that you wish were free and private?"
