+## Plans And Pricing
+
+Pay for provisioned capacity, not workflow semantics. Each namespace receives
+an isolated managed runtime; customer PHP, Python, and Rust workers run in your
+own environment. All five plans are available through Cloud.
+
+| Plan | Runtime capacity | Included durable storage | Availability | Price (USD) |
+| --- | --- | --- | --- | --- |
+| Cloud Dev | 1 vCPU, 1 GB RAM | 5 GB | Single host, no SLA | $0.03/hour, capped at $20/month |
+| Cloud Standard | 1 vCPU, 2 GB RAM | 25 GB | Single-region HA, 99.99% SLA | $100/month |
+| Cloud Multi-Region | 1 vCPU, 2 GB RAM | 25 GB | Multi-region HA, 99.99% SLA | $150/month |
+| Cloud Business | 4 vCPU, 8 GB RAM | 100 GB | Single-region HA, 99.99% SLA | $500/month |
+| Cloud Business Multi-Region | 4 vCPU, 8 GB RAM | 100 GB | Multi-region HA, 99.99% SLA | $650/month |
+
+Capacity covers the managed runtime components, not customer worker compute.
+HA replication and standby capacity are included in the plan price; the table
+does not add replicas together as extra workflow-execution capacity. Every plan
+includes Managed Waterline, basic encrypted backups, upgrades, and a stable
+runtime URL.
+
+Cloud Dev is metered by minute, with a $1 active-month minimum and a $20 cap
+per space per UTC calendar month. SLA plans have a fixed monthly runtime price,
+with applicable plan-change prorations handled by Stripe. Additional durable
+storage is $2/GB-month, metered by GB-hour and separate from runtime charges or
+the Dev cap. Prices exclude applicable taxes. Storage expansion requires
+available capacity; neither disk growth nor network use is unlimited.
+
+See [Cloud pricing](https://cloud.durable-workflow.com/pricing) to choose a plan.
+For larger capacity, different connectivity, SSO, enterprise support, or a
+custom availability requirement, [contact us](https://cloud.durable-workflow.com/contact).

 ## Region Placement And Recovery Boundary
 
-The current 2.0 launch cohort provisions each namespace in one managed region.
-The namespace response exposes that region and its service status for
-residency, latency, and incident decisions; infrastructure deployment
-identities, private addresses, upstream credentials, and provider topology
-remain internal.
+Choose the recovery boundary with the plan:
+
+- **Cloud Dev:** one isolated host with persistent state and backups. Maintenance
+  and recovery may interrupt service. There is no uptime SLA or automatic
+  regional failover.
+- **Single-region HA:** three replicated hosts in one region, with automatic
+  primary failover. One host may fail without losing the remaining quorum.
+  A whole-region outage is outside this plan's SLA coverage.
+- **Multi-region HA:** three replicated hosts across three regions, with
+  automatic primary failover. The SLA includes loss or isolation of one
+  configured region, provided the remaining members can form a quorum.
+
+The stable runtime URL follows the elected primary; you do not change SDK
+configuration during a supported failover. An isolated former primary is
+prevented from continuing to serve authoritative work. If a safe primary
+cannot be established, the runtime stops serving rather than accepting
+conflicting writes. HA is not a promise of uninterrupted requests: clients and
+workers still need bounded retries for transient failures.
+
+The namespace page exposes its topology, region information, and service
+status. Backups support recovery but are not a substitute for live replication.
+Short failover tests demonstrate the exercised failure cases, not a universal
+recovery-time guarantee or a month's achieved availability.
+
+### SLA Measurement And Credits

+The four SLA plans provide a 99.99% uptime SLA over a UTC calendar month,
+measured at the customer runtime endpoint in one-minute windows. Missing
+measurements count as unavailable, and planned maintenance is not excluded.
+Customer-hosted worker availability is separate from managed runtime availability.

-## Cloud Dev Capacity
+## Standard Workflow Benchmarks
+
+[DW Standard Workflow v1](https://github.com/durable-workflow/server/tree/main/benchmarks/capacity)
+defines a small, repeatable workload: one workflow start, one external activity,
+and one workflow completion, with defined 1 KiB Avro inputs and results.
+The customer worker runs outside the managed runtime allocation.
+
+The recorded plan baselines below use that workload. The SLA-plan measurements
+include their replicated HA topology; they are not extrapolated from a Dev host.
+
+| Plan | Standard workflows/second | 30-day workflow actions |
+| --- | ---: | ---: |
+| Cloud Dev | 0.25 | 1,296,000 |
+| Cloud Standard | 0.25 | 1,296,000 |
+| Cloud Multi-Region | 0.10 | 518,400 |
+| Cloud Business | 0.50 | 2,592,000 |
+| Cloud Business Multi-Region | 0.20 | 1,036,800 |
+
+The 30-day estimate is `workflows/second x 2,592,000 seconds x 2 workflow actions`:
+one start and one activity for this comparison. It assumes that rate runs
+continuously for 30 days. It is not an included-action quota, a billing unit,
+or an exact mapping to another engine's action definitions.
+
+These are measured workload baselines, not maximum throughput or guaranteed
+capacity for every application. Larger payloads, more activities, timers,
+signals, queries, replay-heavy histories, cross-region communication, and
+customer worker latency change the result. The table does not claim separate
+timer, signal, replay, or saturation benchmarks. Plan for your actual workflow
+mix rather than multiplying these numbers by an arbitrary workflow size.
