About inputprobe Keyboard Tester and cppq

In their own words, as submitted to SaaSHub.

inputprobe Keyboard Tester
cppq

Press keys and watch them register: per-key counts, auto-repeat filtered out, live count of how many keys are held at once (rollover), and the fastest same-key re-press gap. Deliberately issues no "chatter detected" verdicts, no threshold ships without a measurement behind it; the data is...

Features and specs

What each product offers, as listed by its team.

inputprobe Keyboard Tester 5 features
cppq 5 features
  • No Installation Required
    InputProbe Keyboard Tester runs directly in a web browser, eliminating the need to download or install any software, making it quick and convenient to access from any device with internet access.
  • Real-Time Key Detection
    The tool provides immediate visual feedback when keys are pressed, allowing users to quickly identify which keys are functioning properly and which may be unresponsive or faulty.
  • Free to Use
    The keyboard tester is available at no cost, making it accessible to anyone who needs to test their keyboard without financial investment.
  • Simple and Intuitive Interface
    The layout is straightforward and easy to understand, typically displaying a virtual keyboard that highlights keys as they are pressed, making it user-friendly even for non-technical users.
  • Cross-Platform Compatibility
    Since it's a web-based tool, it can be used across different operating systems including Windows, macOS, and Linux, as long as a compatible browser is available.
  • Lightweight C++ implementation
    cppq is written in modern C++ and designed to be a minimal, efficient task queue library, making it a good fit for performance-sensitive applications where the overhead of scripting language runtimes is undesirable.
  • Redis-backed reliability
    Built on top of Redis as the message broker, cppq benefits from Redis's persistence, atomic operations, and wide adoption, giving the queue system durability and the ability to survive process restarts.
  • Inspired by proven design (asynq)
    The library's architecture mirrors the popular Go asynq task queue, so it inherits a well-thought-out API design for task enqueueing, retries, and worker processing patterns that have already been validated in production systems.
  • Native integration for C++ projects
    For teams already working in a C++ codebase, cppq allows adding background job processing without needing to introduce a separate service written in another language (like Go or Python), simplifying the technology stack.
  • Open source and inspectable
    Being open source on GitHub, developers can review the source code, modify it for custom needs, and contribute improvements, which offers transparency not available with closed-source queueing solutions.

Possible disadvantages

  • Limited maturity and battle-testing
    Compared to established task queue libraries like Sidekiq, Celery, or asynq itself, cppq is a newer and smaller project with less real-world production usage, which may translate into undiscovered bugs or edge cases.
  • Smaller community and ecosystem
    Because it has far fewer users and contributors than mainstream task queue systems, finding community support, third-party tutorials, or pre-built integrations is more difficult.
  • Documentation gaps
    As a smaller project, cppq may have less comprehensive documentation compared to major task queue frameworks, requiring developers to read source code directly to understand advanced features or edge-case behaviors.
  • C++ build and dependency complexity
    Using cppq requires managing C++ build toolchains and dependencies (such as a Redis client library), which can be more cumbersome than installing a package via pip or npm in other ecosystems.
  • Fewer built-in features and tooling
    cppq likely lacks the extensive ecosystem tooling of more mature queues, such as web-based monitoring dashboards, extensive metrics/observability integrations, or advanced scheduling features found in more established solutions.

Overall verdict

  • cppq is a lightweight, Redis-backed distributed task queue for C++ inspired by Go's popular 'asynq' library. It's a good choice for developers who need a simple, dependency-light job queue system in C++ without the overhead of larger enterprise messaging systems, though it's a smaller, less battle-tested project compared to mature alternatives.

Why this product is good

  • Simple and lightweight design makes it easy to understand and integrate into existing C++ projects
  • Built on Redis, a well-established and reliable backend for queue storage, giving it a solid foundation
  • Inspired by asynq (a proven Go library), so the design patterns and task queue semantics are based on a well-thought-out model
  • Open source on GitHub, allowing developers to inspect, modify, and contribute to the code
  • Good fit for projects already using Redis, minimizing the need for additional infrastructure
  • Straightforward API for enqueueing and processing background jobs in C++ applications

Recommended for

  • C++ developers needing a background job/task queue without adopting a heavyweight message broker
  • Projects already using Redis as part of their infrastructure
  • Small to medium-sized applications requiring asynchronous task processing
  • Teams comfortable working with less mainstream or smaller open-source libraries and willing to contribute or debug issues themselves
  • Developers familiar with asynq (Go) looking for a similar pattern in C++
  • Prototyping or hobby projects where a minimal task queue solution is sufficient

Questions & Answers

As answered by people managing inputprobe Keyboard Tester and cppq.

What makes your product unique?

inputprobe Keyboard Tester's answer

It's the keyboard tester that refuses to guess. Most testers ship a "chatter detected!" verdict based on an invented millisecond threshold, but nobody has published where deliberate double-tapping ends and switch flutter begins, and a guessed threshold is how tools end up accusing healthy hardware. This tester shows you the evidence instead: per-key press counts, auto-repeat filtered out, live and maximum simultaneous-key counts (rollover), and each key's fastest re-press time, and leaves the verdict with you, with guidance on how to judge it against your own fastest deliberate double-tap. It's also honest about what a browser can and cannot see: it documents which keys legitimately never reach a web page (laptop Fn, media keys, system shortcuts) so you don't blame working hardware, and it states plainly that rollover is measured as delivered through the OS, not at the keyboard's connector.

Why should a person choose your product over its competitors?

inputprobe Keyboard Tester's answer

Because it won't lie to you in either direction. It never accuses a healthy key with a made-up chatter threshold, and it never clears a dead one, a key that doesn't light gets explained (switch, connection, or a layer below the browser), with the legitimately-invisible keys documented so silence isn't misread as failure. Practical details are handled properly: keys are captured before the browser acts, so Space doesn't scroll and Tab doesn't leave the page, with a Pause button that hands your keyboard back; the board runs on physical key codes, so it works on any layout, not just US QWERTY; and macOS's quirk of not reporting a letter key released while Command is held is corrected rather than counted against the key. Everything runs locally, nothing you type leaves your machine.

How would you describe the primary audience of your product?

inputprobe Keyboard Tester's answer

Mechanical keyboard owners diagnosing a switch that types twice (and deciding whether it's worth a switch swap), anyone checking a used or secondhand laptop's keyboard before buying, gamers verifying that their board actually delivers the rollover it advertises, and people troubleshooting a single dead or flaky key who want to know whether it's the switch, the connection, or the operating system eating the keypress.

What's the story behind your product?

inputprobe Keyboard Tester's answer

It's part of inputprobe, a set of input-device testers built around one rule: a verdict must quote the evidence it's based on, and when the evidence isn't good enough, the tool refuses to judge. For the keyboard tester that rule had a concrete consequence: every other tester publishes a chatter verdict from a threshold nobody has measured, and we haven't yet measured where human double-tapping ends and switch flutter begins on real keyboards, so this page deliberately ships no verdict, displays the timing data, and says exactly why. The reasoning is written up at inputprobe.com/methodology/, alongside what has and hasn't been validated on real hardware across the whole site.

Which are the primary technologies used for building your product?

inputprobe Keyboard Tester's answer

Plain web platform, no frameworks: dependency-free JavaScript ES modules reading KeyboardEvent physical key codes, with events captured ahead of browser default actions so testing doesn't scroll or navigate the page. The site is static HTML generated by a small Python build (Jinja2 + Markdown) and served from Cloudflare's edge. There is no backend, every keystroke is read, counted, and displayed entirely in your browser, and nothing is uploaded.

Who are some of the biggest customers of your product?

inputprobe Keyboard Tester's answer

None to list. It's a free tool with no accounts and no tracking, so we genuinely don't know who uses it, and we prefer it that way.
