I do not know any program like that but what worked for me was creating another user account that had no access to lots of stuff.

LeechBlock for just the browser? And yeah AppArmor for stopping programs from launching.

@Psyhackological @sports games For Linux, I’d probably prefer a combination of existing FOSS tools rather than something that has to run with deep system privileges. LeechBlock is useful for browser distractions, while AppArmor can be used to restrict specific applications.For a full “productivity session” approach, a small script could combine those ideas: temporarily apply the restrictions, start a timer, and provide a simple command to disable them early. That would keep the user in control while still making it inconvenient enough to launch distracting programs.I think the important distinction is whether the restrictions are voluntary and reversible. If it’s something you deliberately enable for yourself and can turn off when needed, it feels quite different from software that tries to enforce restrictions against the owner of the machine.

@Psyhackological @clicker gamesIs there a FOSS Linux alternative to Freedom? I'm looking for something that can start a focus session and block selected apps/websites from launching. I'd really love a privacy-friendly, open-source option.

@Psyhackological horror games You could try LeechBlock NG or ActivityWatch on Linux. LeechBlock is useful for blocking distracting websites during work sessions, while ActivityWatch helps track how you spend your time. Both are open source, though LeechBlock focuses on browser distractions rather than blocking desktop applications.
