De-risk new digital initiatives

Verify performance parity against old and new architecture and applications with traffic replay.

Modernize your tech stack

Legacy software migrations are often necessary to build state-of-the-art products and reduce technical debt long term—but they’re no small feat. Drastic changes to underlying technology can introduce unforeseen performance bottlenecks and system integration issues, not to mention disrupt the customer experience. Speedscale ensures new architecture can handle your real-life traffic scenarios so you’re prepared for prime time.

Validate performance

Record and replay API gateway and ingress traffic against your new platform to quickly find out if it performs the same way.

Prevent production issues

Identify and fix issues, like latencies and unexpected system crashes, well before customers become aware of them.

Minimize risk

Simulate production conditions with none of the risk. Speedscale also redacts PII so that sensitive data is never compromised.

Load Testing

Test at scale

Traffic replication makes testing at scale simpler, safer, and more cost-effective. See how your app holds up against high volumes of inbound traffic, and load test against simulated backends to ensure bottlenecks aren’t coming from your internal APIs.

Service Mocking

Mock internal and external dependencies

Accelerate the migration by mocking necessary backends. Simulate internal and third party and systems for more reliable, affordable testing. No need to spin up costly, end-to-end environments that take days to deploy.


Facilitate experimentation

Generate realistic developer preview environments to test and optimize new code.

Make apples-to-apples comparisons

With Speedscale, you can run controlled experiments that let you compare two different offerings equally, under the same exact traffic conditions. The result: better, more informed business decisions.

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.
