Vayu API Client

No description of Apache Benchmark yet.

Vayu is a free, open source desktop API client that also load tests. Build and send REST and GraphQL requests like you would in Postman, then load test the same endpoint from the same app. Native load testing. A multi-worker C++ engine sustains 50,000+ requests per second, on par with wrk and...

Features and specs

What each product offers, as listed by its team.

Apache Benchmark 4 features
Vayu API Client 6 features
  • Simplicity
    Apache Benchmark is straightforward to use with a simple command-line interface, allowing users to quickly conduct basic load testing on web servers without a steep learning curve.
  • Speed
    Because it is a command-line tool, Apache Benchmark executes quickly and can generate a significant amount of traffic with minimal system resource usage.
  • Wide Availability
    As part of the Apache HTTP Server project, it is widely available on most Unix-based systems and easy to install on others, making it accessible for most developers.
  • Open Source
    Apache Benchmark is open-source software, providing full access to the source code for customization and ensuring there are no costs associated with its usage.

Possible disadvantages

  • Limited Features
    Apache Benchmark is quite limited in its capabilities, providing only basic performance metrics and lacking features such as detailed reporting, analysis, and support for different types of HTTP requests.
  • No GUI
    It doesn’t come with a graphical user interface, which could be a barrier for users who prefer visual representations and more interactive usage.
  • Single URL Testing
    The tool is only capable of testing one URL at a time, which can be a limitation when assessing the performance of more complex, multi-page applications.
  • Limited to HTTP
    Apache Benchmark only supports HTTP and HTTPS protocols, which can be restrictive for testing applications using other protocols.
  • Limited Scalability
    Due to its basic nature, it might not handle very large-scale load testing efficiently and may require additional tools or setups to simulate more extensive server loads.
  • Native load testing
    Multi-worker C++ engine, 50,000+ req/s, on par with wrk
  • Live load test dashboard
    Throughput, p50/p99 latency and errors stream in real time
  • Postman import
    Collections v2.0/v2.1, environments, globals, plus Insomnia and OpenAPI
  • Postman-compatible scripts
    QuickJS runtime implementing the pm.* API
  • MCP server for coding agents
    Claude Code, Cursor, VS Code, Codex and Zed can run requests and load tests
  • Fully local
    No account, no telemetry, no cloud sync; works offline

Questions & Answers

As answered by people managing Apache Benchmark and Vayu API Client.

What makes your product unique?

Vayu API Client's answer:

It's an API client and a load tester in the same app. You build a REST/GraphQL request the way you would in Postman, then load-test that exact endpoint from the same window - no second tool, no second config. The engine is native C++ (multi-worker libcurl event loop), so it does ~57k req/s on my machine, slightly ahead of wrk, while the dashboard keeps streaming p50/p99 live. It also ships an MCP server, so a coding agent can run the same requests and load tests.

How would you describe the primary audience of your product?

Vayu API Client's answer:

Backend and API developers who want to know how an endpoint holds up under load without setting up k6 or JMeter for it. Also teams that can't use cloud-synced API clients - it works offline and behind corporate firewalls. And more recently, people using Claude Code/Cursor who want the agent to actually test the API it just wrote.

Which are the primary technologies used for building your product?

Vayu API Client's answer:

Engine: C++23, libcurl (multi-worker event loop), QuickJS for Postman-compatible scripting, SQLite via sqlite_orm. App: Electron + React 19 + TypeScript, Zustand, TanStack Query, Tailwind CSS v4. Build: CMake + vcpkg for C++, pnpm + Vite for the app. The engine runs as a local sidecar process, so the UI never shares a thread with the load.

Why should a person choose your product over its competitors?

Vayu API Client's answer:

Postman, Bruno and Insomnia are good at sending requests, but none of them load-test, so you end up maintaining a separate k6 or JMeter setup with the same endpoints. Vayu does both from one collection. Compared to the Node/Electron clients, the request work runs in a separate C++ process, so the UI doesn't stall under load. It's free and open source (no paid tier), fully local (no account, no telemetry), and Postman collections plus most pm.* scripts import as-is.

What's the story behind your product?

Vayu API Client's answer:

Every team I've worked on used two tools for APIs - one to build and send requests, another to load-test them - and keeping the two in sync was always a chore. I wanted one app that does both, without an account or anything leaving my machine. So I started building Vayu as a solo side project, with the load engine in C++ so it could keep up with tools like wrk.
