Checkly vs Site24x7 Synthetic Monitoring

Checkly is a monitoring-as-code platform for developers who need to monitor APIs and user interfaces. Its uptime monitor types include URL, TCP, DNS, ICMP, SSL, gRPC, Traceroute, and Heartbeat. Browser Checks use headless browsers to simulate interactions such as logins, checkouts, and form submissions. Playwright Check Suites run full test suites on a schedule and support custom dependencies and shared storage state. The Checkly CLI lets users write checks in code and deploy monitors from a terminal. Listed integrations include Slack, PagerDuty, OpsGenie, Datadog, Grafana, Discord, Terraform, and Pulumi. Checkly says its monitors run from the public internet without installation inside or privileged access to a customer network. It also states that it is GDPR compliant and SOC 2 Type 2 compliant, with end-to-end encryption for stored data, HTTPS for network traffic, and AES256 encryption for database data at rest. The Hobby plan is free; Starter is $24 a month, and Team is $64 a month. Hobby includes 10 uptime monitors, 1,000 browser/Playwright runs, and 10,000 API runs per month.

Site24x7 Synthetic Monitoring simulates multi-step workflows in real browsers to monitor web-application availability, functionality, and performance. A no-code recorder captures browser transactions for playback in Chrome, Firefox, or Edge, and existing Selenium IDE cases in.side format can be imported. Recorded transactions can run from more than 130 global monitoring locations. To investigate a step, the service provides timings, resource waterfall charts, screenshots, and root cause analysis reports. Intelligent Capture detects changes to interactive page elements and updates transaction scripts. The maker highlights logins, checkouts, payments, banking, healthcare portals, e-commerce, and SaaS as use cases. Alerting and workflow integrations include ServiceNow, PagerDuty, Slack, Microsoft Teams, Jira, and webhooks. A fully functional 30-day trial includes web transaction monitoring and requires no credit card to start. Recording allows up to 20 transaction steps with an advanced license.
