  • Recording upload

  • 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 speaking.app and Cozystack.

What's the story behind your product?

speaking.app's answer

speaking.app began with a personal realization. Its founder, Bjarte Sunde, an engineer by training, found that in a world increasingly shaped by AI, the skill that mattered most was still an old one: speaking clearly and confidently when it counts. While working on his own communication, he wanted honest feedback and a private way to practice, without an expensive coach and without waiting until the moment had already passed.

The product is built on a simple belief: how you come across in an interview, a pitch, or on stage should not come down to luck or budget. Everyone deserves a place to rehearse, hear how they actually sound, and improve before it matters. What began as a personal tool is now used by individuals, founders, students, and organizations to turn high-stakes speaking from something you hope goes well into something you have prepared for. Built in Dublin by Prosody Ltd, speaking.app is working toward a future where confident communication is something anyone can develop, not a privilege of the few.

What makes your product unique?

speaking.app's answer

speaking.app analyzes both how you speak and what you say, then coaches you until it becomes second nature.

  • Delivery analysis on every session: pacing (words per minute), pauses, filler words, and clarity.
  • Smart Rewrite detects which of 15 speech frameworks (such as STAR or PREP) your answer is closest to, scores how well you follow it, and rewrites it in that structure.
  • Founder pitch analysis maps a startup or investor pitch to the 13 elements investors listen for, rates each, and returns an investor-style verdict from Strong Yes to Pass.
  • Coaching feedback after every session tells you what to work on next, so each practice run has a clear focus.

Most tools stop at delivery metrics. speaking.app tells you what to fix, shows you how, and helps you rehearse it until it sticks.

Why should a person choose your product over its competitors?

speaking.app's answer

Choose speaking.app because it does more than measure your delivery. It helps you fix it and rehearse until you are ready.

  • It goes past delivery metrics. Beyond pacing and filler words, you get structural feedback and an AI rewrite of what you actually said, so you improve the substance, not just the surface.
  • It coaches you, then you iterate. After each session it tells you what to work on next, so every practice run has a focus and progress compounds.
  • It is built for specific, high-stakes moments. A dedicated pitch analysis for founders (the 13 elements investors listen for, with a verdict), plus 1,400+ real interview questions for named companies, roles, accelerators, and admissions.
  • It works solo or across a whole program. Practise on your own, or run a cohort from a coaching dashboard (accelerators, universities, coaching firms).

It is practice software for getting genuinely better beforehand, not a live in-call copilot.

How would you describe the primary audience of your product?

speaking.app's answer

speaking.app is for people with a high-stakes speaking moment coming up, and the organizations that train them.

  • Individuals: job seekers rehearsing interviews, startup founders preparing pitches and demo day, and professionals practising presentations and public speaking.
  • Organizations running structured practice programs: accelerators, universities, and coaching firms that use a coaching dashboard to manage participants and track progress.
  • Toastmasters and clubs: members use the free filler-word Ah-Counter and speech timer to run and time their meetings, no account needed.

Which are the primary technologies used for building your product?

speaking.app's answer

speaking.app is a modern web application. There is nothing to download or install.

  • Proven, industry-standard stack: Next.js and React on the front end, Python (FastAPI) on the back end.
  • AI at the core: speech is transcribed with AI speech-to-text; the analysis, coaching feedback, and Smart Rewrite are powered by large language models.
  • Runs anywhere: works in any browser as a Progressive Web App (PWA), installable on any device.
