Find bottlenecks before your users do

See where your system breaks. Stop guessing.

"Capacity planning today is educated guessing. Real validation happens in production."

Bottleneck Studio lets you test your assumptions before they become incidents.

How It Works

Build

Drag sources, queues, and workers onto the canvas to model your system

Configure

Set arrival rates, processing times, concurrency, and failure rates

Simulate

Run thousands of messages through your model and see where it breaks

What You Can Do

Lognormal distribution editor with percentile fitting

Model realistic latency

Choose from multiple distribution types to match how your services behave in production.

Start
Staged load profile editor

Simulate traffic spikes

Shape traffic with ramps, spikes, or custom curves to see how load affects your system.

Fault injection configuration

Inject failures

Introduce outages, degraded performance, or latency spikes to test system resilience.

Failure domains configuration

Test correlated failures

Model availability zones and shared dependencies that can fail together.

Variables panel

Run what-if scenarios

Parameterize your model and tweak values on the fly to explore tradeoffs.

Results showing latency and throughput

Measure what matters

See latency percentiles, throughput over time, and whether you're meeting your SLOs.

Connection bandwidth limit configuration

Model bandwidth limits

Cap connection throughput to see how network constraints ripple through your system.

Wait-for-all join strategy

Handle fan-in patterns

Synchronize parallel paths, deduplicate messages, or race concurrent requests.

Connection guard selector

Build error paths

Route failures, timeouts, and rejected messages to retries or dead-letter queues.
