AlertSite is a synthetic monitoring platform for websites, web applications, APIs, mobile experiences, and other connected resources. It is designed for development, quality, operations, and enterprise teams that need more than basic availability checks. Monitoring can run from global public locations or private nodes inside customer networks. The platform covers browser transactions, REST and SOAP APIs, multi-step API workflows, response validation, and journey checks, making it suited to customer-facing services and internal applications with several dependencies.

Pricing follows a contact-sales model, and there is no free plan. The dedicated trial offering provides 30 days for evaluation. The published product scope focuses on tailored monitoring rather than a simple self-serve package comparison, so buyers should expect to discuss requirements with SmartBear Software. AlertSite supports operational workflows through integrations with PagerDuty, Slack, OpsGenie, VictorOps, and AppDynamics, while Splunk and Google Analytics extend reporting and analysis use cases. ReadyAPI, SoapUI, Selenium, and OpenAPI/Swagger support fit development and testing ecosystems.

Its standout capability is transaction validation across browser and API paths. DeJaClick records and replays browser transactions, while API monitors can validate responses, retry checks, and verify failures from multiple locations before raising an alert. Dashboards, SLA reporting, waterfall analysis, and a REST API for monitor and results automation add depth for teams managing service performance at scale. AlertSite is a strong fit when transaction accuracy, private network coverage, and verified alerting matter. Teams seeking only straightforward uptime checks may prefer a narrower tool with simpler packaging and less operational scope.
