UptimeRobot Alternatives for Domain & SSL Expiry Monitoring
UptimeRobot is one of the most popular monitoring tools on the web, and for good reason — its free plan gives you 50 uptime monitors, which is genuinely generous. But if you came to it specifically to be warned before a domain or SSL certificate expires, there's a detail worth knowing before you set everything up.
The catch: expiry monitoring isn't on the free tier
UptimeRobot does support both SSL certificate expiry and domain (WHOIS) expiry monitoring. But those are paid-only monitor types — the free plan covers uptime, not expiry. So the exact reason many people reach for UptimeRobot ("it's free") doesn't apply to the thing they actually want here.
That's not a knock on UptimeRobot as an uptime tool. It just means that if expiry alerts are your priority — especially on a budget — it's worth comparing alternatives that treat expiry as a first-class, and often free, feature.
Here's the honest rundown.
DomainChest — (ours) expiry on the free tier
We build DomainChest, so treat this as the interested party's pitch — but it exists precisely for the gap above. It tracks every domain and SSL certificate you own, across any registrar, and its expiry monitoring works on the free tier (3 domains) rather than behind a paywall. Alerts go out over email, Slack, and webhooks with a staged runway (well before the deadline, not the morning of).
What it deliberately isn't: a full uptime/response-time suite. If you need latency graphs and incident on-call, UptimeRobot or one of the platforms below fits better. If you just need to never miss an expiry, this is the shortest path — and you can test a single domain or cert free with our domain expiry checker and SSL checker without signing up.
StatusCake — free tier includes one SSL and one domain check
StatusCake is an uptime-first tool that, unlike UptimeRobot, includes one SSL test and one domain test on its free plan (alongside three uptime monitors). If you want a free option that covers expiry and you only have a domain or two to watch, it's a real contender. Paid plans (from around $20/mo) raise those limits substantially.
Oh Dear — the strongest all-in-one, but paid
If budget isn't the constraint, Oh Dear has the closest thing to first-class domain and SSL expiry monitoring of any general site monitor — full certificate-chain checks, WHOIS expiry, broken links, uptime, all included on every plan. The trade-off is there's no free tier (from ~€15/mo, priced per site).
Better Stack — expiry as part of incident management
Better Stack (formerly Better Uptime) pairs uptime with on-call scheduling, status pages and logs, and supports SSL and domain/TLD expiry as monitor settings. It has a free tier (10 monitors), though it's worth confirming on their live pricing whether SSL/TLD-expiry monitoring is included free or needs the paid Responder plan (~$29/mo) — sources differ.
Site24x7 — if you want a full platform
Site24x7 is a broad infrastructure/APM platform with SSL/TLS and domain expiry monitors built in. There's no permanent free tier (trial, then from roughly $9/mo), and it's more product than most people need if expiry alerts are the whole goal — but it's a fit if you're consolidating onto one heavyweight tool.
Which should you pick?
| If you want… | Consider |
|---|---|
| Expiry alerts, free, across registrars | DomainChest (free tier) or StatusCake (1 SSL + 1 domain free) |
| Uptime and expiry in one paid tool | UptimeRobot (paid), Better Stack, StatusCake |
| Best all-in-one, budget no object | Oh Dear |
| Full APM platform | Site24x7 |
The one question that cuts through all of it: does the plan you're actually on watch both the domain clock and the SSL clock, for every name you own? With UptimeRobot's free tier, the answer for expiry is no — so make sure whatever you choose closes that gap.
