HetrixTools Free Plan pricing & rate limits

• The base tier provides a starting point of 15 monitored targets and 1 team seat at a $0.00/mo baseline.
• Scaling beyond the free tier moves into custom pricing models where HetrixTools negotiates based on the total volume of endpoints, competing with alternatives like UptimeRobot or Pingdom.
• Incident alerting is not gated by volume, meaning you receive unlimited notifications regardless of how frequently your infrastructure flaps or enters a degraded state.
• Check frequency intervals are configurable, though aggressive sub-minute polling intervals will shift you out of entry-level pricing tiers quickly.

Managing uptime monitoring across a distributed fleet requires balancing the number of active checks against your monthly spend. While the initial 15 targets cover standard internal services or small web clusters, growing teams will eventually hit the seat constraint. Adding team members is often the first trigger for moving off the free plan into enterprise-grade contracts. Because incident volume is unlimited, you do not need to worry about being penalized for noisy alerts during a cascading failure or a botched deployment cycle. Unlike raw compute platforms that charge for NVMe storage or CPU cycles, this platform focuses exclusively on synthetic probe data and status page availability.

This service is effective for engineering teams that need reliable heartbeat monitoring without worrying about alert fatigue costs. It handles the alerting overhead for infrastructure hosted on providers like Vultr or Linode, provided you keep your monitored target count within the initial threshold. If your primary goal is maintaining visibility across a growing microservices architecture, you will eventually reach the limit of the free tier and need to engage their sales team for a custom quote that accounts for your specific target density.
