In their own words
Quartz Scheduler
Quartz Scheduler is a free, open-source Java library for running application tasks at scheduled times or on recurring plans. Triggers can use times, days, calendar exclusions, repeat counts, end dates or intervals. Quartz says it can handle workloads from tens to tens of thousands of jobs, with JTA transaction and clustering support. It can run inside an application, an application server or servlet container, as a standalone RMI program, or as a cluster of standalone programs. JDBCJobStore persists jobs and triggers in a relational database, while RAMJobStore keeps them in memory and loses them between executions. Data sources can come from JDBC, application-server JNDI or custom ConnectionProvider implementations. Built-in clustering depends on JDBCJobStore persistence. Downloads list version 2.5.1 for Java 11+ with the jakarta namespace and 2.4.1 for Java 8 with javax.*. Quartz describes itself as a scheduler rather than a job queue, although it can serve as one at small scale. It is licensed under Apache License 2.0.
Webcron
Webcron is a cloud service for scheduling web-accessible scripts and monitoring servers, websites, and routers. Jobs can run once or on a schedule as often as every minute, with timeouts up to one hour. Users can choose notifications for successful or failed jobs. Monitoring checks whether targets can be reached from more than one location, using HTTP, HTTPS, FTP, or ping at intervals from 1 to 60 minutes. Monitors can compare page content, look for a specified string, and add custom request headers.
The API communicates directly with the Webcron engine, and its documented methods cover cron jobs and monitors. A PHP class is available for API connections and is stated to support PHP 5.0 and later. The maker lists monitoring stations in the United States, Japan, Singapore, Ireland, Brazil, Germany, France, South Korea, and Australia. Webcron has no free plan and offers a 14-day trial; monitoring can be tried free for one week or until credits are used up. Listed per-launch prices include free for a 180-second timeout, €0.01, paid once for 600 seconds, €0.13, paid once for 1800 seconds, and €0.25, paid once for 3600 seconds. Email alerts cost €0.01 and SMS alerts cost €0.15.
