TierZero review
A broad incident and CI/CD assistant for teams that need remediation workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
TierZero is an AI production-agent platform for engineering, SRE, and platform teams. It investigates incidents, performs root-cause analysis, groups alerts, reduces noise, answers infrastructure questions, diagnoses CI/CD failures, detects flaky tests, and generates fix pull requests. Approved remediation can include rollback, restart, and feature-flag actions. The platform also creates postmortems, timelines, and action items, while runbook and SOP execution includes permissions and audit logging.
Pricing starts with the Starter plan at $75 per user per month or $900 per user per year. Starter includes coding agent integration and 20 free alert investigations per month. Pro costs $100 per user per month or $1,200 per user per year, adding API access, external SSO, and RBAC. Enterprise adds pooled credits, on-prem deployment, enterprise SSO/SAML, a 95% accuracy guarantee, and a 99.5% uptime SLA. There is no free plan, so the product is aimed at teams prepared to fund a dedicated incident and delivery-assistance layer.
TierZero fits environments built around observability, incident management, code, documentation, and CI/CD tools. Integrations include Datadog, Grafana, New Relic, PagerDuty, Opsgenie, Slack, GitHub, Confluence, Notion, Buildkite, GitHub Actions, CircleCI, Cloudflare, Temporal, and Databricks. It is available through the web and API, with cloud or self-hosted deployment; Enterprise supports on-premises deployments for AWS and GCP. Choose TierZero when incident response and CI/CD diagnosis need to work together. Teams seeking only basic alert handling, or teams without budget for paid per-user software, should consider a narrower option.
