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

Hook0 is an open source Webhooks-as-a-Service platform that helps developers send, receive, manage, and monitor webhooks at scale. It is built for teams that need to add webhook support to their product without spending weeks building retry logic, signatures, monitoring, queues, dead letter handling, event logs, and subscriber management from scratch. With one API call, teams can publish outbound events, while Hook0 handles delivery infrastructure, configurable retry logic, webhook calls, endpoint monitoring, event persistence, and developer tooling. It keeps track of every event an application sends and every webhook call it makes, helping teams debug integrations, inspect delivery attempts, and maintain an audit log. Hook0 supports secure webhook delivery with HMAC signatures, key rotation, TLS encryption, and compliance-focused deployment options. As a fully open source platform, it allows teams to audit the codebase and self-host on their own infrastructure.
