Deliver exceptional digital experiences

Optimize your digital storefront, streamline retail operations, and sharpen your competitive edge with Speedscale’s production traffic replication service.

Protect the customer experience

Your customers love the convenience of your app—but when software changes lead to unexpected bugs or worse, downtime, it can leave customers with a bad experience and cause your business to lose out on revenue. Speedscale lets you test with real traffic so you can ship code changes confidently.

Ensure reliability during seasonal spikes

Gain confidence that new
code changes can handle high traffic scenarios. Mimic real-
life peak usage, or third party system outages with payment providers and geolocation. Debug issues before they occur in production.

Increase developer productivity

De-risk new digital initiatives, like legacy software migrations, and get started with little operational overhead so your team can move fast without disrupting the customer experience.

Reduce costs and improve profit margins

Simulate high throughput end-to-end systems at a fraction of the cost and identify new opportunities to save money by observing and replaying API traffic.

Load Testing

Know your limits and breakpoints

See how your app holds up against high volumes of inbound traffic. Speedscale not only shows you latency and throughput metrics, but also CPU and memory—so you know exactly what your app’s maximum capacity is.

Service Mocking

Model behavior of third party services

Create intelligent simulations of third party systems, like your shipping, payment, inventory, and fulfillment providers for more accurate and cost-effective testing.

Legacy Software Migration

De-risk new digital initiatives

Seamlessly migrate off legacy architecture without disrupting the customer experience. Record and replay API gateway and ingress traffic against your new platform to quickly find out if it performs the same way.

API Observability

Quickly examine and pinpoint problems

Drill down into specific subsets of traffic and view the exact details of each call, including message payloads, headers, cookies, authentication tokens, and more.

How it works


Speedscale captures your app’s traffic via Sidecar, Postman collections or JSON files.


Identify service use patterns and mask sensitive data.


Continuously replay scenarios as part of the CI pipeline.

Data Privacy & Security

Prevent data loss and protect PII

Redact sensitive data and personally-identifiable information (PII) on the fly. Anonymize traffic while keeping data structure intact for more accurate and useful testing.
