Usage
$0 / month platform fee
Start without a commitment. Pay for the sandbox resources you allocate.
- $0.030 / vCPU-hour
- $0.010 / GiB-hour of memory
- Proposed per-second compute billing
- Same rate across consuming services
Sandbox infrastructure
Pay for the room
your services need.
Proposed launch pricing / USD
More room to run.
Less spent on compute.
One usage model across every consuming service. No per-seat fee. These are proposed rates; public billing and checkout are not available yet.
Build / Monthly subscription
$20 / month · includes $25 sandbox credits
A monthly sandbox budget alongside the coding tools you already subscribe to.
- $25 of resource credits each billing month
- Base CPU and memory rates
- Monthly credits reset; top-ups roll over
- Model subscriptions stay with your provider
Committed
$250 / month minimum spend
For predictable workloads. The commitment covers usage; it is not an extra platform fee.
- 15% off CPU and memory
- $0.0255 / vCPU-hour
- $0.0085 / GiB-hour of memory
- Unused commitment expires monthly
Dedicated
Custom / capacity agreement
Plan a dedicated pool for sustained demand across your services.
- Capacity and term priced together
- Hardware and region agreed upfront
- Support requirements scoped separately
- Subject to capacity review
Make it concrete
Estimate your compute.
Runtime is the sum across all sandboxes: 100 sandboxes × 10 hours = 1,000 hours.

Official public rates checked September 7, 2026; Cloudflare Containers checked September 30, 2026. E2B Pro adds $150/month; its Hobby tier has no platform fee but different limits. Daytona lists usage-based pricing. Modal’s sandbox rate uses physical cores (1 core = 2 vCPUs); we divide its CPU rate by two. Modal bills the higher of requested and actual resources; this estimate uses the requested amount. Cloudflare Containers bills in 10 ms steps only while a container is active, adds a disk charge ($0.00000007 per GB-second) that is not included here, and includes a small monthly allowance on its $5 Workers plan. Hardware performance, limits, credits, regions, and support differ. This is a resource-price comparison, not a performance benchmark or total-bill quote.

What else is billed?
Workspace snapshots, available now: $0.021/GB-month stored, prorated per second and charged daily; $6.30 per million write operations and $0.504 per million reads; no egress charge. Other retained storage (proposed): $0.08/GiB-month, prorated by time. Proposed internet egress: $0.05/GiB after 100 GiB per organization per month. Ingress is free. These charges are outside the calculator; committed discounts apply only to CPU and memory.
When does compute stop?
The proposed meter runs while CPU and memory are allocated, including idle and provisioning time. Compute stops once resources are released. Retained storage remains billable. Persistent-tier sandboxes can be paused, which ends compute charges until they are resumed; workspace snapshots keep files past a sandbox’s lease.
What is available today?
Condensation is an internal preview. These plans guide the commercial model; they do not enable subscriptions, payments, service-scoped quotas, or an SLA. Rates need validation against fleet costs before paid availability.
