Question 1

What do I get on a paid plan that I can't get for free?

Accepted Answer

Plimsoll does not offer a perpetual free tier. Every paid tier — Starter ($9/workload/month), Team ($29/workload/month), and Enterprise ($99/workload/month) — includes the full three-signal agent (infrastructure, application, and FinOps), cross-stack anomaly correlation, fenced auto-remediation, and PagerDuty/Slack escalation. The tiers differ by fleet size and collaboration features: Starter covers up to 25 workloads on one cluster; Team adds multi-cluster correlation, auto-approved spend playbooks, SSO, and SCIM for up to 250 workloads; Enterprise removes the cap and adds a dedicated tenant, custom data residency, roadmap input, and a named partner engineer. A pilot window is arranged on request.

Question 2

What counts as an incident for billing purposes?

Accepted Answer

Nothing — Plimsoll bills per monitored workload, not per incident or alert. One workload is one agent deployment: a cluster, a service group, or a cloud account boundary you define. No matter how many correlated anomalies the agent detects, resolves, or escalates in a month, your bill is workload count multiplied by the tier rate. Alert noise or a quiet week changes nothing.

Question 3

How long are logs and reports retained?

Accepted Answer

Starter retains anomaly graphs, remediation records, and incident reports for 30 days. Team extends retention to 90 days with full audit-log export. Enterprise sets retention by contract — default one year, longer on request — and supports a custom data-residency region. Raw telemetry lives in your own OTLP/Prometheus pipeline; Plimsoll only persists the correlated-event layer.

Question 4

Can I switch plans mid-cycle?

Accepted Answer

Yes. An upgrade takes effect immediately and is prorated for the remainder of the billing month — you pay only for the days on the higher tier. A downgrade takes effect at the start of the next billing cycle, so you keep the higher-tier features through the period you've already paid for. There is no migration fee or re-provisioning step. If your workload count exceeds the new tier's cap at downgrade time, you'll be prompted to reduce workloads or stay on the current tier.

Question 5

What happens if I exceed my workload cap?

Accepted Answer

Plimsoll does not automatically charge overages. If your monitored workload count reaches the tier cap — 25 on Starter or 250 on Team — the agent pauses onboarding of additional workloads and notifies your account contact. You can remove an existing workload to make room, or upgrade to the next tier to expand the cap. Nothing is billed without your explicit action; there is no surprise charge at the end of the month.
