About
Load Multiplier is a highly scalable software testing solution designed for performance, load, stress, and capacity testing of various network protocols and applications, including VoIP, HTTP, Web, WebRTC, JSON, XML, SIP, IMS, and custom proprietary protocols. It acts as a simulator for endpoints and servers, allowing users to simulate real-world traffic scenarios.
Best for
Teams that want managed load generation without operating injectors
Organizations budgeting for commercial licenses or subscriptions
Groups comfortable scripting in Unknown
Not the best fit when
New greenfield programs (prefer an active successor or alternative)
Strictly air-gapped environments with no approved cloud path
Projects that require a fully free open-source stack only
Architecture and concurrency
Load Multiplier runs as a cloud service: scenarios use Unknown, while generators and orchestration are vendor-managed.
Features
Support for web, custom, HTTP, WebSocket, WebRTC, VoIP, SIP, IMS, RTP, SRTP, JSON, XML, and STUN/TURN/ICE protocols
Scalable simulation of millions of endpoints
Wrapper functionality to act as a simulator over existing software instances
Pricing
Offers a free version limited to 100 virtual users for one month; otherwise, specific pricing information is not publicly disclosed.
Load Multiplier is best for teams that want managed load generation without operating generators themselves. It is commercial software, typically licensed for larger or governed programs. Vendor: Load Multiplier. Deployment model: cloud. Historical pricing not verified. Confirm details against the official site and a short proof-of-concept in your environment.
How does Load Multiplier differ from Apica?
Compared with Apica, scripting centers on Unknown rather than JavaScript. Load Multiplier lists protocols HTTP, HTTPS; Apica lists HTTP, HTTPS, REST. Status is discontinued 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 Load Multiplier use?
Load Multiplier uses Unknown for scripting or scenario definition. Runtime model: protocol-oriented virtual users configured through the product workflow. OS support: Browser. Protocols: HTTP, HTTPS. 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 Load Multiplier?
Load Multiplier is cloud-hosted: you run tests on vendor-managed infrastructure without operating load generators yourself. That usually speeds ramp-up for distributed load while shifting capacity planning and data residency to the vendor. Pricing model: Historical pricing not verified. Confirm details against the official site and a short proof-of-concept in your environment.
What are known limitations of Load Multiplier?
Load Multiplier appears as discontinued in this directory. Prefer No verified successor or another active alternative for new work. Historical references remain so older docs and diagrams still resolve. Verify any remaining commercial support directly with the vendor before depending on it.
