Not all free tiers are equal. Here's what each actually gives you.
Compare every free uptime monitoring tool — monitor counts, check intervals, status pages, and commercial-use limits. 55, 50, 10, 10 — which free tier wins?
Most uptime monitoring tools offer a free tier, but the differences are significant. Some restrict free use to non-commercial projects, some limit you to 10 monitors, some don't include status pages or cron job monitoring, and some hold back monitor types on the free plan. A "free tier" isn't always as free as it looks.
The four tools below are the only mainstream uptime monitors with a permanent free tier worth considering. I compared them across monitor count, check interval, commercial-use policy, status pages, monitor types, and cron job availability. The table makes the trade-offs obvious — there's no single winner, just the right fit for your situation.
All figures were verified on 3 August 2026 against each vendor's own pricing page and terms of service.
| Feature | SurePing Our tool | UptimeRobot | Better Stack | StatusCake |
|---|---|---|---|---|
| Free monitors | 55 | 50 | 10 | 10 |
| Check interval (free) | 5 min | 5 min | 3 min | 5 min |
| Commercial use allowed | Yes | No | Yes | Yes |
| Free status pages | 2 | 1 | 1 | 0 (paid only) |
| All monitor types on free | Yes (all 6) | Yes (all 7) | Most (no keyword on free) | Limited |
| Cron job monitoring (free) | Yes | Yes | Yes | No |
| Multi-region checks (free) | No (single region) | Yes | No (paid only) | Yes |
| Native Slack integration (free) | Via webhook | Yes | Yes | Yes |
SurePing's free tier gives you 55 monitors at 5-minute intervals, 2 status pages, all six monitor types (HTTP, keyword, ping, port, SSL, and heartbeat), and no commercial-use restriction. It's the most generous free tier on this list by monitor count, and the only one that lets you use all monitor types — including keyword and heartbeat — without paying.
The trade-off is single-region checks. UptimeRobot and StatusCake both run free-tier checks from multiple regions, which helps distinguish real outages from regional routing faults. SurePing also uses webhook-based integrations for Slack and Discord rather than native one-click connections — functional, but slightly more setup.
Best for: solo developers, small businesses, and side projects who want the most monitoring capacity for $0 and don't need multi-region checks.
UptimeRobot offers 50 free monitors with all seven monitor types (including DNS), 20+ native integrations (Slack, Discord, Teams, PagerDuty), and multi-region checks. It's the most mature free tier and the most widely integrated — if you want one-click Slack alerts without touching a webhook URL, this is the one.
The catch is the non-commercial restriction. UptimeRobot's terms restrict the free tier to non-commercial use, so if you're monitoring a business website, a SaaS app, or anything that generates revenue, you're expected to upgrade to a paid plan. The free tier also defaults to annual billing on the upgrade path, which can be confusing.
Best for: non-commercial projects — personal sites, open-source projects, hobby apps — that want a proven, widely-integrated monitor with multi-region checks.
Better Stack's free tier is 10 monitors at 3-minute intervals — the smallest on this list. But it includes log management and on-call scheduling, which no other free tier here offers. If you want to try monitoring, logging, and incident response together without paying, Better Stack is the only option.
The limitations are real: 10 monitors is tight for anything beyond a single small project, keyword monitoring isn't available on the free plan, and multi-region checks require a paid plan. On the plus side, the 3-minute check interval is the fastest free-tier interval on this list — faster than SurePing and UptimeRobot's 5 minutes — which is a point in Better Stack's favor if you care about check frequency over monitor count.
Best for: teams who want to evaluate monitoring + logs + on-call together, and can work within 10 monitors.
StatusCake gives 10 free monitors at 5-minute intervals with SSL certificate monitoring and domain expiration checks included. Page-speed monitoring is also available. If certificate and domain management is your priority, StatusCake bundles those capabilities into the free tier where others charge for them or don't offer them.
The gaps: no free status pages (status pages are paid only), no cron job / heartbeat monitoring, and the UI feels dated. The 10-monitor limit is also restrictive compared to SurePing's 55 and UptimeRobot's 50. Multi-region checks are available on the free tier, which is a plus.
Best for: teams who want SSL and domain expiration monitoring alongside uptime, and don't need cron job monitoring or a free status page.
If you want the most free monitors with no strings attached, SurePing's 55-monitor free tier is the clear winner. You can monitor commercial sites, use all six monitor types including keyword and heartbeat, and get 2 status pages — all for $0. No other free tier matches that combination of capacity, monitor types, and commercial-use permission.
If you need multi-region checks or native Slack integration on the free tier, UptimeRobot is the alternative — but only for non-commercial use. If you want logs and on-call bundled in, Better Stack is the only option — but with just 10 free monitors. SurePing wins on raw capacity and flexibility; the trade-off is single-region checks and webhook-based integrations.

For most users, SurePing — it offers 55 free monitors with no commercial-use restriction, all six monitor types, and 2 status pages. UptimeRobot is a strong alternative with 50 free monitors and native integrations, but restricts free use to non-commercial projects.
UptimeRobot offers 50 free monitors, but the free tier is restricted to non-commercial use. If you're monitoring a business website, a SaaS app, or anything that generates revenue, you're expected to upgrade to a paid plan. SurePing and Better Stack both allow commercial use on their free tiers.
For a single website with HTTP and SSL checks, 2-3 monitors are enough. For a small SaaS with a web app, API, database, and SSL certificate, you'll want 5-8. SurePing's 55-monitor free tier covers most small projects comfortably; Better Stack and StatusCake's 10-monitor limits are tight for anything beyond a single site.
SurePing (2 status pages), UptimeRobot (1), and Better Stack (1) all include free status pages. StatusCake does not — status pages are paid only on StatusCake.
Yes, but not with every tool. SurePing and Better Stack allow commercial use on their free tiers. UptimeRobot restricts its free tier to non-commercial use — if you're monitoring a business site, you need a paid plan. StatusCake allows commercial use on its free tier.
