A side-by-side comparison of 3AM Super Intelligence and Mermaid — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
3AM Super Intelligence
3AM Super Intelligence
AI on-call engineer that investigates production incidents on-prem, proves the root cause against live systems, and fixes it with one human approval.
Key features
- Evidence-Based Root Cause Analysis: Runs read-only checks on live systems and rules out hypotheses, so a fix is proposed only when the cause is proven.
- One-Tap Approval: Sends fixes for approval in Slack, Symphony, PagerDuty, phone or email, with every action dry-run first.
- Per-Service Autonomy Levels: Everything starts in shadow mode; raising a service's autonomy takes two approvers while lowering is instant.
- Tamper-Evident Audit Ledger: Logs every signal, check, approval and action in a hash-chained, signed ledger exportable to your SIEM.
- On-Prem Deployment: Runs inside your network with no inbound ports, suited to banks and other regulated environments.
- Broad Stack Integrations: Connects to Prometheus, Grafana, Datadog, PagerDuty, Jira, GitHub, GitLab, Bitbucket, Kubernetes, MySQL, PostgreSQL, Oracle, Slack, Symphony and Twilio.
- Runbook and Code Search: Searches runbooks and code scoped to the affected service to ground its investigation.
