Mature product with broad feature surface — broken-link checking, scheduled-task heartbeats, cron monitor.
- /strength · 02
Strong dev community + an active blog from the Spatie team.
- /strength · 03
Self-hostable runner option for paranoid clients.
Where Pleenx differs
- /angle · 01
Pleenx is positioned around agency client portfolios specifically — white-label PDF, branded subdomain, group-by-client. Oh Dear is a great single-team tool but not white-label-first.
- /angle · 02
Pleenx's three-tier alert windows (30/14/3 days) are agency-tuned defaults. Oh Dear is more granular/configurable, which is a tradeoff: power vs zero-setup.
- /angle · 03
Pricing: Pleenx scales to 25/100/300 domains across tiers; Oh Dear's cheapest tier is 10 sites with smaller increments.
