Features and specs

What each product offers, as listed by its team.

Cozystack 5 features
Brubru 6 features
  • 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.
  • My EU Bubble
    Brubru's main dashboard, allowing you to monitor all the EU legislative items, according to your policy interests.
  • Chat
    Brubru's chatbot, which narrates anything you need to know: EU laws, processes, people, stakeholders, institutions, and much more.
  • Amendator
    An amendment editor for official amendments to the European Parliament, powered with AI.
  • EU Law Comply
    Comply with EU law easily and quickly.
  • Tenderator
    Monitor and manage all the EU's funding programmes, with the help of AI.
  • API
    Brubru's API gives you ALL the data from the europa.eu digital ecosystem: more than 900 endpoints fetching data from more than 8000 websites. It also has an MCP and two Python libraries.

Questions & Answers

As answered by people managing Cozystack and Brubru.

What makes your product unique?

Brubru's answer:

Brubru is a developer-first API for the entire EU legal and policy corpus: over 17,000 laws across 900+ structured endpoints, machine-readable and AI-ready. Where most EU intelligence tools are closed dashboards, Brubru exposes the whole canon programmatically, so teams and AI agents can query, cite and build on EU law directly. Its motto: "All the EU, with AI".

Why should a person choose your product over its competitors?

Brubru's answer:

Tools like FiscalNote and Politico Pro are expensive, closed platforms built for reading, not for building. Brubru is API-first and agent-ready: structured, machine-readable EU law you can integrate into your own apps, workflows and AI systems. It is EU-native, affordable, and designed for developers and policy teams who need data out, not just a dashboard to log into.

How would you describe the primary audience of your product?

Brubru's answer:

Developers, GovTech and RegTech builders, EU public affairs and policy professionals, compliance and legal teams, and AI teams that need reliable, structured EU legal and regulatory data as an input to their own products and agents.

What's the story behind your product?

Brubru's answer:

Brubru is built by Beresol, a Brussels-based software company founded by Victor Solé Ferioli specialising in GovTech, AI integration and discoverability, GIS and web development for EU public affairs. Brubru grew out of a simple problem: EU law is public but not programmable. It turns the fragmented EU legal corpus into a single, structured, AI-ready API, sharing Beresol's motto "All the EU, with AI".

Who are some of the biggest customers of your product?

Brubru's answer:

Ferrmed, GovClipping.

Which are the primary technologies used for building your product?

Brubru's answer:

TypeScript, Node.js, React, a REST/JSON API, PostgreSQL, hosted on Railway.
