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.<p>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.
