Oh Dear treats a website as a whole: uptime, SSL, DNS, cron, broken links, mixed content, and Lighthouse. Webalert treats external availability and incident response as the center of the product. That is the useful frame for Oh Dear vs Webalert in 2026.
The short answer
Choose Oh Dear for the capabilities in its column that your team genuinely uses. Choose Webalert for focused HTTP/HTTPS, TCP, DNS, ping, and heartbeat monitoring with multi-region confirmation, SSL alerts, status pages, and incident alerting. Neither choice is a universal upgrade.
| Dimension | Oh Dear | Webalert |
|---|---|---|
| Unit of pricing | Per site (plans start at 17 per month for two sites, all features, unlimited users — confirm currency at checkout) | Per monitor (Free 3 monitors, then €9/month Starter, €29/month Business) |
| Uptime plus SSL, DNS, and cron checks | Yes | Yes |
| Whole-site crawler (broken links, mixed content) | Yes | No |
| Lighthouse audits and monthly client reports | Yes | No |
| Multi-region availability checks | Confirm in the vendor's docs | Yes |
| Incident and on-call workflows | Not the product's focus | Incidents, status updates, maintenance windows |
| Best fit | Agencies that need per-site health reports | Teams that need availability plus incident communication |

Pricing and packaging
Oh Dear's pricing page displays plans starting at 17 per month for two sites and includes all features and unlimited users; its terms describe prices in euros, so confirm currency and tax at checkout. Webalert starts Free with 3 monitors; its paid tiers expand monitor counts, intervals, alert channels, pages, and operational features. See the current Webalert pricing and feature matrix rather than assuming every feature is on every plan.
Choose Oh Dear when
- You manage client sites and need crawls, lighthouse, and monthly website-health reports.
- You prefer one per-site bundle with all checks and unlimited users.
- Broken links and mixed content matter as much as downtime.
Choose Webalert when
- You need multi-region availability plus incident and on-call workflows.
- You price work by endpoints rather than whole sites.
- Crawler and lighthouse reports are not part of the requirement.
Important limitation
Webalert does not reproduce Oh Dear’s whole-site crawler, mixed-content checks, Lighthouse audits, or agency reports. Oh Dear should stay where those outputs justify the subscription. This is why a hybrid can be the right answer: keep the specialist workload and move only simple outside-in checks.
Migration advice
Classify every Oh Dear check as uptime, SSL/DNS/domain, cron, crawler, or Lighthouse. Move only the first groups. Keep crawler and Lighthouse coverage, then compare one monthly client report before changing an agency process.
