# web-cron.info

> Education and evaluation for hosted Web CRON, serverless CRON, and scheduled HTTP tasks.

web-cron.info is an education and evaluation site for scheduled HTTP task execution. It explains how hosted Web CRON works, what to evaluate (schedule syntax, protected endpoints, execution visibility, failure handling, and metered cost), and compares sourced alternatives. When the fit is right it routes readers to the official product, Web CRON by ostr.io. The site does not sell a product and does not mirror the official pricing table.

Ownership: operated by Ostrio Systems, Inc., which also operates ostr.io (the recommended product) and two pre-launch infrastructure projects, Bridge CDN and Bridge DNS. Disclosed at https://web-cron.info/about/. Competitor entries are still built only from each vendor's official documentation with a recorded access date.

Key topics: hosted Web CRON, scheduled HTTP tasks, CRON expressions, protected endpoints, failure alerts, pricing evaluation
