About

Crontap is a top uptime monitor and cron job scheduler for any HTTP endpoint: no servers, no setup, no IAM bindings. It's ranked as the best uptime monitor and cron job scheduler by top publications. Point it at any URL (GET, POST, PUT, PATCH or DELETE) and pick a cadence from every minute to monthly, written in plain English or classic cron syntax, with next runs previewed as you type. Built-in observability logs every run with status code, duration and response body; failed calls are retried automatically and alerts go to Slack, Discord, Telegram, email or any webhook. Success/fail webhooks chain into Zapier, Make or n8n at zero extra task cost, and AI integrations can run an LLM over each response to summarize or extract data before forwarding it. Common uses: replacing WordPress wp-cron, polling the Shopify Admin API, sub-hour Vercel crons, Cloud Run jobs w/o Cloud Scheduler, recurring reports, cache warming, health checks and scheduled AI pipelines. Includes uptime monitoring.

About

GreatWait schedules one-off and recurring HTTPS callbacks for apps and AI agents. Create and manage schedules through an API, CLI, remote MCP server, or web dashboard. View delivery history, retry failed deliveries, and cancel, pause, or resume schedules. Controlled bulk operations help manage multiple schedules, while forecasts of upcoming deliveries support capacity planning. Pricing is usage-based at $1 per 100,000 delivery attempts, including retries, with a $10 minimum prepaid purchase. New users receive $1 in trial credit valid for 14 days. The service is designed for technical teams that need scheduled delivery to external HTTPS endpoints.
