## What it is
Hyperfoil is a distributed Java load-testing framework designed for high-throughput microservice benchmarks and coordinated-omission-resistant latency measurement. Its benchmark language supports HTTP/1.1, HTTP/2, and HTTPS scenarios executed by clustered agents.

## Choose it when
- Load Testing scenarios across typical web and service stacks
- Teams that prefer open-source licensing and self-hosting options
- Groups comfortable scripting in Java, YAML

## Look elsewhere when
- Teams unwilling to operate generators, results storage, and scaling

## Architecture
Hyperfoil is commonly operated as self-hosted software with scenario authoring in Java, YAML. Concurrency and distribution depend on how you size workers or injectors.

## Pricing
Free; Apache License 2.0.

## FAQ
### Who is Hyperfoil for?
Hyperfoil is best for engineers designing load, stress, and performance tests for web and service systems. It is open source, so teams can self-host and extend it. Vendor: Red Hat. Deployment model: self-hosted. Free; Apache License 2.0. Confirm details against the official site and a short proof-of-concept in your environment.

### How does Hyperfoil differ from Apache JMeter?
Compared with Apache JMeter, scripting centers on Java, YAML rather than Java, Groovy. Hyperfoil lists protocols HTTP, HTTPS, HTTP/2; Apache JMeter lists HTTP, HTTPS, JDBC, JMS, FTP, TCP. Status is active versus active. Use the Test Rig to compare full specs side by side before a proof-of-concept.

### What scripting language and concurrency model does Hyperfoil use?
Hyperfoil uses Java, YAML for scripting or scenario definition. Runtime model: code-first scenarios where virtual users execute scripted behavior under load. OS support: Windows, macOS, Linux. Protocols: HTTP, HTTPS, HTTP/2. Match these to how your team already authors tests and which systems you must drive under load.

### What is the cloud or enterprise path for Hyperfoil?
Hyperfoil is primarily self-hosted; teams typically run generators on their own machines, CI runners, or private cloud. Plan for generator capacity, network access to targets, and result storage yourself. As open source, commercial support or hosted siblings may exist separately. Check the official site. Pricing note: Free; Apache License 2.0.

### What are known limitations of Hyperfoil?
Hyperfoil limitations to weigh: self-hosted tools require you to provision, scale, and observe load generators yourself. Status: active. Always validate against your target protocols and scale with a proof-of-concept. Confirm details against the official site and a short proof-of-concept in your environment.
