Show HN: Cron SaaS. Would you pay to run custom Node.js jobs periodically?

I wouldn't. Many cron tasks are used for diagnostics, and must continue to work even when your web stack doesn't. Other cron tasks run a long time and NGINX will kill processes that seem unresponsive. Other cron jobs must not be started twice (so they require locking). Cron isn't perfect, but it's very simple and completely reliable.

I think you should focus on SaaS products that you can charge at least a few hundred a month for. If people aren't even willing to pay that much you're probably not solving a big enough problem.

Are you aware that this is not a new idea and that are already a lot of these services running out there?

I wouldn't and also pretty sure that I won't use it even if its free . Only time I had to use a similar system was when using shared hosting without shell access.

How much? 1 Dollar for 10 Years, or on which price you think?

Given that the Heroku scheduler is completely free, no.

No. Is this an example of a Service As A Service?

No, I wouldn't.

No
