When to Choose FocusGuard

Variable schedule — your focus needs change daily; you want to start/stop blocking on demand
Quick setup — you want to be blocking sites within 10 seconds of install
Positive motivation — you respond better to rewards (puppies) than punishment
Pomodoro-style work — you work in focus sprints with breaks in between
Simple needs — you just want to block specific sites during focus time, nothing more

When to Choose LeechBlock

Fixed schedule — you want the same blocking rules every weekday automatically
Daily time limits — "allow 10 minutes of Reddit per day" rather than full blocking
Complex rules — you need regex matching, multiple rule sets, per-site time allowances
Firefox user — LeechBlock supports Firefox; FocusGuard is Chrome-only
Open source preference — LeechBlock is open source and fully auditable
Set-and-forget — once configured, LeechBlock runs automatically without manual session starts

The Key Difference: Timer vs Schedule

This is the fundamental difference between the two tools:

	FocusGuard (Timer)	LeechBlock (Schedule)
Start blocking	You click "start" when ready	Automatic at scheduled time
Stop blocking	Timer expires (auto)	Schedule window ends (auto)
Flexibility	Different every day	Same routine daily
Requires discipline to...	Start the session	Configure rules correctly
Best work style	Variable, creative	Structured, routine

Bottom line: If your days are structured and predictable, LeechBlock's automation is convenient. If your schedule varies or you work in sprints, FocusGuard's on-demand approach fits better.

Frequently Asked Questions

Is FocusGuard or LeechBlock better?

It depends on your work style. FocusGuard is better for flexible, on-demand focus sessions — start blocking when you need it, stop when your timer ends. LeechBlock is better for fixed daily schedules with automatic rule enforcement. FocusGuard is simpler; LeechBlock is more configurable.

What's the difference between FocusGuard and LeechBlock?

FocusGuard uses timer-based blocking (you decide when to focus), LeechBlock uses schedule-based rules (blocking happens automatically at configured times). FocusGuard adds positive motivation (puppy rescue); LeechBlock offers more granular controls like regex matching and daily time limits.

Is LeechBlock free?

Yes, LeechBlock NG is completely free and open source. FocusGuard also has a free tier with full blocking functionality. Neither tool requires payment for basic website blocking.

Which website blocker is easiest to set up?

FocusGuard is significantly easier: install → add sites → start timer (10 seconds total). LeechBlock requires configuring rule sets, time periods, and blocking conditions — powerful but takes 5-15 minutes of initial setup.
