I built Procrastinope, an open-source alternative to Cold Turkey Blocker that focuses on privacy.
Cold Turkey Blocker is fantastic, but I was frustrated that it required trusting closed-source software that can see effectively all activity on my computer.
The main differentiator for Procrastinope is transparency -- unlike proprietary blockers, you can inspect exactly what it's doing to your system. In short, it works by modifying `/etc/hosts` and includes several anti-bypass features:
- Challenge-protected controls (type random strings to disable blocks)
- Auto-restart daemon to prevent killing the process
- Anti-tamper logic which prevents manual edits to /etc/hosts config files
- System-level blocking across all browsers
