YouLMK vs Healthchecks.io

YouLMK or Healthchecks.io?

Healthchecks.io, in its own words: "Simple and Effective Cron Job Monitoring": it notifies you "when your nightly backups, weekly reports, cron jobs, and scheduled tasks don't run on time", free for 20 jobs, open source, run by one person since 2015 with 652 paying customers as of July 2024. YouLMK is an inbox you let things interrupt you through: anything with an HTTP client sends into it, and you decide per sender how far a message may reach, whether quiet hours hold it and how repeats group. It can also watch a page, an endpoint, a status page, a feed, a number or a time, and send when the answer changes.

Healthchecks.io

YouLMK

What it is

A dead man's switch for cron jobs: each job pings a URL when it runs, and you are told when a ping is late.

A hosted inbox with rules per sender, that also watches pages, endpoints, status pages, feeds, numbers and times.

Price

Hobbyist free for 20 jobs and 100 log entries per job; Supporter $5 a month with the same limits; Business $20 for 100 jobs, Business Plus $80 for 1,000; 20 percent off yearly.

Send $4 a month or $40 a year for unlimited notifications; Watch $12 or $120 adds watching. Trial: 10 notifications and 3 watches, no card.

Open source

Yes, self-hostable.

No.

What it watches

That a job checked in on time; also the job's exit status and its output through the ping.

That a page, an endpoint, a status page, a feed, a number or a time changed; not that a job failed to run.

Where the notification lands

28 integrations: email, Slack, Discord, Telegram, PagerDuty, Pushover, ntfy, Gotify, webhooks and more; YouLMK through its webhook integration.

Its own inbox on iPhone, Android and the web, with email, Slack and a signed webhook as destinations.

Rules on the receiving side

The notification service's own.

Per sender: a Reach level, quiet hours that hold, grouping, which destinations.

Choose Healthchecks.io if

You need to know when a job did not run at all, which a notification at the end of the job cannot tell you.
You want it free for 20 jobs, or self-hosted, with a service you already use for the alert.

Choose YouLMK if

You want the job's own result on your phone, with rules: the failed one loud, the routine one silent, with its log one tap away.
You want the same inbox for everything else that sends to you, and watches on pages, endpoints and prices.
Both, in fact: Healthchecks.io watching the schedule, notifying YouLMK, with the job's own line at its end.

What is the same

Both are one-person-sized tools for people who run things, both have a free way to start, both take one HTTP call from a job. Healthchecks.io watches the schedule; YouLMK is where the result lands, with rules.

Try it

The trial is 10 notifications and 3 watches, no card, no clock. Get your key, or read the docs first.
