# TCP Checks GA

Published Feb 20, 2025

## TCP checks are now generally available

TCP checks are fully available across all plan types. Monitor critical infrastructure like databases, messaging queues, or mail servers by specifying a hostname and TCP port, with assertions on response time and response data. They are integrated into Monitoring as Code workflows: available in the CLI from v4.19.1, the Terraform provider from v1.9.0, and the Pulumi provider from v2.0.0.

## Pricing and billing

TCP checks are billed at $2 per 10k runs and share the same quota as API checks, meaning they are included in your existing API check allocation.
