Capacity planning — know how much traffic your design can take
Model instances, roles, runtimes, and connections once. Pregoo estimates requests per second, p95 latency, and the first bottleneck for each role, using Sourced measurements from its technology catalog where they exist and clearly labeled estimates where they do not. The same model feeds the cost estimator and Realtime Tracking. Free · no signup needed to try.
- Sourced vs Estimated — Every figure says where it came from, so numbers can be defended in a design review.
- Workload scenarios — Compare normal, peak, and launch-day traffic and see which role fails first.
- Right-size before you buy — Spot oversized VMs and under-provisioned databases before they reach the bill.
- Saved reports — Keep named performance and cost reports next to the project and export them to PDF or Excel.
- Step 1: Model the infrastructure — Start from a template or Quick create, then adjust instances, roles, and apps.
- Step 2: Run a scenario — Set expected users and traffic, then read RPS, latency, and bottleneck hints.
- Step 3: Price and track it — Send the model to the cost estimator, then compare it with live servers.
Frequently asked questions
Where do the capacity numbers come from?
From measured benchmarks in the Pregoo technology catalog (labeled Sourced) and from documented estimates based on instance size and runtime (labeled Estimated). They are planning figures, not live measurements.
Can I try capacity planning without an account?
Yes. Open Projects to start a guest project and model infrastructure right away. Create a free account to run and save performance reports.
