About cppq and Lapsus

In their own words, as submitted to SaaSHub.

cppq
Lapsus

No description of cppq yet.

Lapsus is a keyboard layout switcher for Windows and macOS. When you type in the wrong layout, it retypes the line in the right one on the spot. There is no deleting, no manual language switching, and no typing it all again. It handles Latin, Cyrillic, Greek, Hebrew, Arabic, and Georgian. Besides...

Features and specs

What each product offers, as listed by its team.

cppq 5 features
Lapsus 0 features
  • 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.

Analysis

An editorial look at what each product does well and who it suits.

Lapsus

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 cppq and Lapsus.

Which are the primary technologies used for building your product?

Lapsus's answer:

.NET 10 and Avalonia, so the same app runs on Windows and macOS.

What makes your product unique?

Lapsus's answer:

It retypes a line typed in the wrong layout, on your own computer, with no account and no telemetry. One app covers Windows and macOS and six writing systems: Latin, Cyrillic, Greek, Hebrew, Arabic, and Georgian.

How would you describe the primary audience of your product?

Lapsus's answer:

People who write in two languages with different scripts, and keep typing in the wrong layout. The strongest fit is companies whose teams work across regions and switch layouts all day.

What's the story behind your product?

Lapsus's answer:

I kept hitting the same problem: a whole line typed in the wrong layout. The tools I tried were either worse, or they sent some of what I typed to the internet. That was not acceptable, so I built Lapsus to fix the line on the computer itself, with no account and no telemetry
