Sysmos brings API health checks, Linux server monitoring, and a centralized dashboard together for teams that need to track services and infrastructure. Synthetic checks run API endpoints across global regions and report status, SSL details, latency, and timing across DNS, TCP, TLS handshake, server processing, and content transfer. Per-phase averages and maximums are available over 1-hour, 24-hour, and 7-day periods. For multi-step checks, the flow builder chains API steps, extracts variables, and applies assertions; flows can run on demand or on a schedule. A Linux agent for x86_64 and arm64 uses eBPF to collect syscall, network, CPU, and memory data. Sysmos states that the agent’s CPU overhead is under 2%. Alerts can go to Slack, Discord, PagerDuty, email, or HTTP endpoints through webhooks. Workspaces include admin, developer, and viewer roles, as well as API keys for CI/CD and infrastructure-as-code. The Free plan is free; Team is 29.00 USD per month and Business is 99.00 USD per month. Sysmos lists API, Linux, and web platforms, and describes the service as designed for small teams.
Who it is for
Sysmos suits solo developers and personal projects on its Free plan, as well as small teams that need API checks, Linux server data, and shared monitoring. Teams that need scheduled API flows, alert routing, or role-based workspace access can use those built-in capabilities.
