Plans and limits

What the limits actually mean
Minimum check interval is the fastest you may check. Free is limited to 60 seconds, so the 30-second option is unavailable.
Check regions per monitor caps how many regions run each check. On Free you get 1 region and it is chosen for you; Pro and Business let you pick your regions. More regions is the single most effective way to stop a bad network path causing false alarms.
On-demand checks per hour covers manual Check now runs, not your scheduled checks. Scheduled checks are governed by the interval.
History retention is how long individual heartbeats are kept. Hourly statistics let you see trends over a longer window.
Hitting a limit
Glowo refuses the action and tells you which limit you reached. Nothing that already exists stops working — you cannot create monitor number 11 on Free, but your 10 keep running.
Limits are enforced at the database level as well as in the application, so concurrent requests cannot slip past a limit by racing each other.
Which plan
Free is a genuine free tier, not a trial. It suits a personal project or one service: 10 monitors, a status page, email and chat alerts.
Pro is the point where monitoring becomes a team activity — more people, your own regions, 30-second intervals, SMS, maintenance windows, and a status page on your own domain.
Business adds the things organisations need rather than teams: SSO, an audit log, 365 days of retention, and headroom at 500 monitors.
Changing plan
Billing runs through Stripe.
GET /billing/subscription # current plan
GET /billing/usage # usage against limits
POST /billing/checkout # upgrade
POST /billing/portal # manage payment details, invoices, cancelThe portal is Stripe’s own, so card details never touch Glowo.
Check /billing/usage before downgrading. Dropping to a plan whose limits you
already exceed is the situation you want to discover deliberately rather than
by surprise.
