About Mouse Tester and Cozystack

In their own words, as submitted to SaaSHub.

Mouse Tester
Cozystack

When a mouse starts acting weird (double-clicking, missed clicks, scroll wheel jumps), it’s surprisingly hard to prove what’s happening — especially when you’re trying to troubleshoot quickly or decide whether to replace hardware. So I made a lightweight, browser-based mouse tester with instant...

Features and specs

What each product offers, as listed by its team.

Mouse Tester 3 features
Cozystack 5 features
  • Visual button map
    Visual button map (Left / Right / Middle / Side buttons)
  • Double-click issue detection
    (helps spot unintended extra clicks)
  • Scroll wheel jump/direction checks
    Scroll wheel jump/direction checks (catch “scrolling the wrong way” or jumping)
  • Free and Open Source
    Cozystack is a fully open-source platform (under Apache 2.0 license) built on top of proven open-source technologies like Kubernetes, Talos Linux, and FluxCD, allowing users to inspect, modify, and contribute to the codebase without vendor lock-in.
  • All-in-One PaaS/IaaS Platform
    Cozystack provides a comprehensive platform that combines PaaS and IaaS capabilities, offering managed Kubernetes clusters, databases (PostgreSQL, MySQL, Redis, etc.), virtual machines, load balancers, and monitoring out of the box, reducing the need for multiple separate tools.
  • Built on Battle-Tested Technologies
    The platform leverages well-established cloud-native technologies such as Kubernetes, KubeVirt for virtualization, Kamaji for managed Kubernetes, and Cilium for networking, providing a solid and reliable foundation rather than reinventing the wheel.
  • Simplified Bare-Metal Deployment
    Cozystack is designed to be installed directly on bare-metal servers using Talos Linux, making it relatively straightforward to set up your own cloud infrastructure without needing pre-existing cloud providers or complex manual configurations.
  • GitOps-Driven and Declarative Management
    Using FluxCD and Helm charts under the hood, Cozystack follows GitOps principles, enabling declarative infrastructure management, reproducible deployments, and easy customization of platform components through a standardized workflow.

Possible disadvantages

  • Steep Learning Curve
    Cozystack requires solid knowledge of Kubernetes, Talos Linux, networking, and various cloud-native technologies. Users unfamiliar with these ecosystems may find the initial setup and ongoing management challenging.
  • Relatively Young and Small Community
    Compared to established platforms like OpenStack or major managed Kubernetes services, Cozystack has a smaller user community, which means fewer community-contributed resources, tutorials, third-party integrations, and slower issue resolution from peers.
  • Limited Enterprise Support and Ecosystem
    As a relatively new open-source project, Cozystack lacks the extensive enterprise support contracts, professional services, and partner ecosystems that more mature platforms offer, which may concern organizations requiring SLA-backed support.
  • Hardware and Infrastructure Requirements
    Cozystack is designed for bare-metal deployments and requires a minimum cluster of nodes with specific hardware capabilities (e.g., for KubeVirt virtualization), which may not be accessible or cost-effective for smaller teams or those without dedicated infrastructure.
  • Limited Documentation and Maturity
    Being a newer project, the documentation can be sparse or incomplete in certain areas, and some features may still be evolving, potentially leading to breaking changes or gaps in functionality compared to more mature alternatives.

Questions & Answers

As answered by people managing Mouse Tester and Cozystack.

What makes your product unique?

It’s designed to be fast, simple, and instantly understandable—so users can confirm what’s happening within seconds.

Who are some of the biggest customers of your product?

Mouse Tester's answer

Mouse Tester is currently aimed at the general public and support use cases rather than enterprise accounts. Users typically include individuals troubleshooting peripherals, gamers, and IT/helpdesk staff who need quick browser-based verification. (If you have specific customer names or logos later, you can add them here.)

Why should a person choose your product over its competitors?

Mouse Tester's answer

Mouse Tester focuses on the checks people actually need when a mouse feels “off”:

  • Clear visual feedback for every button press (including side buttons)

  • Practical double-click issue detection to spot unintended repeats

  • Scroll wheel jump/direction checks to catch erratic scrolling

It’s also lightweight and straightforward—no installs, no accounts, and a clean UI that gets you to a result quickly.

Mouse Tester's answer

Mouse Tester is built for:

  • Everyday users troubleshooting mouse issues at home or work

  • IT/support teams who need a quick way to validate mouse input in a browser

  • Anyone buying/repairing peripherals who wants a simple verification tool

What's the story behind your product?

Mouse Tester's answer

Mouse Tester started as a practical fix for a common problem: when a mouse begins double-clicking or the scroll wheel starts jumping, it’s hard to prove the issue quickly. The goal was to create a browser-based tester that makes mouse input visible and easy to diagnose—so users can confirm the problem before changing settings or replacing hardware.

Which are the primary technologies used for building your product?

Mouse Tester's answer

Mouse Tester is a web app built with a modern front-end stack:

  • Next.js (static export / no-backend deployment)

  • React + TypeScript

  • Tailwind CSS and shadcn/ui for UI components
    Core diagnostics are implemented with standard browser mouse and wheel events.
