Reliable cron job service - FastCron | WarmIndex

FastCron is a reliable online cron job service that schedules and executes HTTP requests to user-specified URLs, perfect for developers and teams automating recurring tasks on websites without server-side cron access.

🚀 Overview

FastCron is a cloud-based cron job scheduler that has been reliably running tasks since 2009, originally launched as SetCronJob and rebranded in 2023. It solves the common pain points of traditional server cron jobs, such as unreliability, lack of access on shared hosting, and difficulty managing across multiple sites or teams. By simply providing a URL, FastCron sends HTTP requests at precise scheduled times, triggering your scripts seamlessly.

This project is built for website developers, webmasters, indie makers, and development teams who need flexible, customizable scheduling for tasks like WordPress cron replacements, API pings, backups, or any HTTP-triggerable automation.

Founded by solo full-stack developer Thuan from Vietnam, FastCron was created to deliver high-availability cron services hosted on robust infrastructure, serving over 8,000 customers and executing 12 million jobs daily with features like team collaboration and extensive integrations.

✨ Key Features

Fast & Flexible Scheduling: Cron jobs from every second to yearly using crontab expressions or simple intervals, with custom timezones and DST handling (why it matters: precise timing for global apps).
Fully Customizable HTTP Requests: Set method (GET/POST/etc.), headers, post data, auth, cookies, user agent (why: adapts to any API or script endpoint).
Smart Automation: Auto-retry failed executions, repeat jobs until/when output matches a pattern, one-time jobs via API (why: reduces manual intervention).
Team Collaboration & Notifications: Unlimited members, real-time logs, alerts via email, Slack, Discord, Telegram, webhooks, Jira, etc. (why: scales for teams).
Optional: Powerful REST API for programmatic cron management.
