What It Is

Dejal Systems, LLC is a small independent macOS and iOS software company with roots dating back to 1991. Its product lineup includes Time Out, Simon, Weather Events, Preminder, Pack, and more. The product most relevant to business software is Simon: a flexible server monitoring tool that runs on macOS, rather than a traditional browser-login SaaS platform.

Core Features and Integrations

Simon covers scenarios such as website outage and change detection, Ping, DNS, RSS, FTP, application checks, disk status, IMAP/POP/SMTP, mounted volumes, SNMP, SSH, TCP port scanning, and more. It also supports other services such as NTP, SMB, and screenshots. Its main strength is the ability to customize services, filters, and notifiers—for example, extending check logic with scripts, or sending alerts via email, iMessage, sounds, speech, web GET/POST requests, app launch, volume mounting, and other methods. It can also save and upload HTML reports, making it suitable for technical users who want a lightweight operations dashboard.

Collaboration, Permissions, and Security

Simon 5 supports iCloud sync, allowing users to view and edit from multiple Macs and designate specific Macs to run checks and notifications. It also offers password protection and background operation. However, the available text does not show team-level SaaS capabilities such as multi-user accounts, role-based permissions, or audit logs. On privacy, Dejal states that it does not sell or share mailing lists or similar information; orders are securely processed through PayPal and FastSpring, and IP addresses may be recorded for diagnostics and security. No compliance certifications such as SOC 2, ISO 27001, or GDPR are disclosed.

Pricing and Purchase

A new Simon purchase costs $99, while upgrades cost $49, following a one-time purchase/upgrade model. Dejal’s Mac software offers a fully functional free trial, and purchases from the Dejal store include a 60-day unconditional money-back guarantee. Payment methods include PayPal, FastSpring, and credit cards. Some macOS apps are available via the Mac App Store or Setapp, while iOS apps are available through the App Store.

Pros, Cons, and Best Fit

Its advantages include native macOS support, broad monitoring protocol coverage, flexible script-based extensibility, friendly trial and refund policies, and free support directly from the developer. Its drawbacks are its clearly Apple-centric ecosystem, lack of cloud-based centralized management, team permissions, and compliance disclosures. It is not ideal for organizations that require enterprise-grade SLAs or a cross-platform monitoring platform. It is better suited to Mac users, independent developers, small-team site operations, or anyone who needs a local monitoring tool.

Access from China and Alternatives

The crawled text does not provide information about access speed, availability, or local payment options in mainland China, so this remains unknown. If you need cloud-based SaaS monitoring, compare UptimeRobot, Pingdom, StatusCake, and Better Stack. If you need self-hosted or enterprise-grade observability, consider alternatives such as Zabbix and Prometheus/Grafana.
