  • 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 flatpass and Cozystack.

What makes your product unique?

flatpass's answer

flatpass is built on the premise that the payment relationship belongs to you, not the platform.

Payments settle into your own Stripe account through Stripe Connect Standard. Not a platform balance you withdraw from on someone else's schedule — your account, your balance, instant settlement, no rolling reserves or minimum payout thresholds. Your customers, their payment history, and your ability to email them are yours from the first sale. Revoke the connection whenever you like and you keep every bit of it.

Everything else follows from that. The invite page is a real hosted checkout, not a bot DM — members see your tiers, pay with cards, Apple Pay, or Google Pay in their own currency, and get their role instantly. Renewals, failed payments, and cancellations are handled without you touching anything.

And because flatpass isn't processing your money, it doesn't need a cut of it. Free up to 15 paid members, then a flat monthly tier metered on community size — never a percentage of your sales, at any volume.

Why should a person choose your product over its competitors?

flatpass's answer

Your Stripe, not a platform balance. Several competitors mention Stripe, but the account is often theirs. With Stripe Connect Standard the account is yours — instant settlement, no rolling reserves, no withdrawal fees, and the customer relationship stays with you if you leave.

No API keys. flatpass authorizes through Stripe Connect Standard — an OAuth grant you approve in your own Stripe dashboard and revoke there in one click. Some Discord payment bots instead ask you to paste your Stripe secret key into their dashboard. That key is unscoped: it can charge, refund, read your entire customer list, and change payout details, and the only way to revoke it is to rotate it. Stripe's own guidance is not to share secret keys with third parties. flatpass never asks for one and has nothing of yours to leak.

A product that feels finished. A hosted invite page rather than a bot DM flow, local-currency checkout, annual billing, multiple role tiers per server, and a public status page. Every feature is on every tier — nothing is held back for a higher plan.

How would you describe the primary audience of your product?

flatpass's answer

Discord community owners who already have an audience and are monetizing access to it — trading and investing groups, creator and fan communities, coaching and cohort programs, professional and industry servers, gaming communities with supporter tiers, and study or skills groups.

The common thread is that members are already arriving through the owner's own channels: a following, a mailing list, a podcast, an existing free server. These owners don't need discovery — they need billing and role management that doesn't scale its price with their success.

flatpass is free up to 15 paid members, so it costs nothing to start — and past that, a flat tier replaces a percentage that would otherwise grow with every sale. It's built for owners who want to keep the Stripe account, customer data, and payment relationship in their own hands rather than on a platform. EU-based, with sellers in any country Stripe supports.
