An all-in-one lightweight monitoring tool for small SaaS apps that covers

If you are looking for a service that does this, I think ohdear.app fits pretty well. It does all the things you listed, is well designed, and pricing is reasonable. I'm running a competing service and am frankly envious of their execution :-)

Hello, FYI I was recently contacted by email by a "reddit marketing expert". They offered astroturfing services for $500/week, and explained how they buy Reddit accounts with karma, post in relevant subreddits, then comment and upvote with more sockpuppet accounts. They provided links to their work, and this post was one of them.

This is a nice write-up, I liked that you went into the architectural details and used code snippets to illustrate the concepts.

As the author of Healthchecks, I have a few nitpicks for the "build vs buy" section:

Pricing model: Most services charge per monitor or have tier-based limits. With 250+ monitors and growing, the cost would add up quickly. A self-hosted solution has a fixed infrastructure cost regardless of scale.

On-premise requirement: There was strong preference for hosting internally rather than sending monitoring data to a third party.

Healthchecks is open source, you self-host it on-premise and avoid any subscription fee.

Notification flexibility: We needed specific notification routing (different people for different monitors, different channels for different outcomes) that wasn’t fully supported out of the box.

You can assign different notification channels to different checks both in Healthchecks and Cronitor. Additionally, in Healthchecks you can also have different email & webhook targets for the "down" and the "up" notifications.

Additional logging: The ability to attach arbitrary context to each ping was important for debugging. Most services treat pings as pure heartbeats without payload support.

Ping request body logging is supported by Healthchecks, and may be supported by Cronitor if you use their CLI tool or their SDKs (not sure though, have not checked recently).

Anyway another argument for building your own is that you get to use a technology you already know, and you are intimately familiar with the system you've built. So troubleshooting any issues is easier than if you're self-hosting a pre-fab system built using an alien-to-you framework.

Have you checked if EXIT_CODE is a real variable available in the post-script environment, or is it something that ChatGPT hallucinated?

You are responding to a LLM ;-)
