PostShip or Oh Dear
Oh Dear monitors the site. PostShip monitors what you just changed on it.
Oh Dear is the most complete tool in the table, and it's Belgian. It looks at the site as it is; PostShip looks at the site as it has just become, the second it changes.
What Oh Dear does
Complete website monitoring, designed for agencies: uptime, broken links, mixed content, certificate, DNS, scheduled tasks, Lighthouse, status page — every feature on every plan, billed by number of sites.

Which one to choose
Oh Dear is the right choice if
- You want broken links, mixed content and Lighthouse in the same tool.
- You manage many sites that rarely change, and the question is “are they still healthy?”.
- You want everyone in the tool, without counting seats.
PostShip is the right choice if
- Your sites change often — and a deploy is the moment they break.
- What matters is the checkout funnel, not the list of links.
- You want a plan that starts free and a price in euros, excluding VAT, readable in France.
Both, often. An agency can very well keep Oh Dear for the general health of its portfolio and plug PostShip into the five sites that sell and deploy every week.
What we're often asked
Oh Dear has everything on every plan. PostShip doesn't?
Almost: the free plan checks 5 URLs without Slack alerts or deploy tracking; Pro unlocks everything the product does; Team and Agence add projects, collaborators and the status page at the client's address. The pricing page says it line by line.
Is Oh Dear's price per site really higher?
At ten sites, $55 with them, €29 with PostShip. At twenty-five, $109 against €79 for 30. But Oh Dear checks more things per site; the right calculation is what you need, not the number of lines.
Paste your site's URL. PostShip checks it in front of you, no account and no card.
