Features and specs

What each product offers, as listed by its team.

SiftingIO 6 features
Cozystack 5 features
  • Real-Time Market Data
    Live quotes, trades, and market updates where supported
  • Historical Data
    OHLCV candles, tick-level history, and historical market data for supported assets
  • REST and WebSocket APIs
    REST snapshots and historical requests, plus WebSocket streams for live updates
  • Multi-venue aggregation
    Market data aggregated, de-duplicated, and normalized across supported venues and sources
  • Enterprise Support
    SLA-backed plans, DPA, invoicing, security review, and dedicated support available
  • Unified JSON Schema
    Consistent fields, authentication, and integration flow across supported asset classes
  • 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 SiftingIO and Cozystack.

Which are the primary technologies used for building your product?

SiftingIO's answer

SiftingIO is built on a modern API and data infrastructure for real-time and historical market data delivery.

The platform uses technologies and engineering patterns around:

  • REST APIs for snapshots, historical data, and reference data
  • WebSocket streams for live market data updates
  • Cloud infrastructure for scalable API delivery
  • Multi-region architecture for reliability
  • API authentication and scoped access control
  • Market data normalization and schema design
  • Data aggregation and de-duplication pipelines
  • Historical time-series storage and retrieval
  • SDKs and developer tooling for integration workflows

The focus is on building a reliable data infrastructure that can serve financial applications, dashboards, trading tools, research systems, and enterprise workflows.

What makes your product unique?

SiftingIO's answer

SiftingIO is built around a simple idea: market data should be easier to integrate, but not simplified to the point where it becomes unreliable.

The platform combines real-time and historical data across multiple asset classes under one API structure. Teams can work with stocks, FX, crypto, commodities, DEX, and on-chain markets without maintaining separate schemas, authentication models, and integration logic for each source.

What makes SiftingIO different is the engineering layer behind the API:

  • Unified JSON schemas across supported asset classes
  • REST and WebSocket access from the same product family
  • Multi-venue aggregation and normalization
  • Historical and real-time workflows in one platform
  • API design focused on consistency, versioning, and maintainability

This makes SiftingIO useful for teams that care not only about accessing data, but also about keeping their data infrastructure clean and scalable.

Why should a person choose your product over its competitors?

SiftingIO's answer

SiftingIO is a strong choice for teams that need market data across more than one asset class and want to avoid maintaining multiple vendor integrations.

Many financial applications start with one market, then expand into others. A team may begin with FX or crypto, then later need stocks, commodities, DEX data, or on-chain metrics. SiftingIO is designed for that kind of growth.

Key reasons to choose SiftingIO:

  • One API structure across supported markets
  • Real-time and historical data workflows
  • REST snapshots and WebSocket streams
  • Unified schemas that reduce integration complexity
  • Multi-venue aggregated and normalized data
  • Developer resources including documentation, SDKs, and Postman examples
  • Enterprise-ready options such as SLA-backed plans, DPA, invoicing, and dedicated support

The main value is not only data access. It is reducing the engineering cost of using market data across financial products.

How would you describe the primary audience of your product?

SiftingIO's answer

SiftingIO is built for technical and data-driven teams working with financial market data.

The primary audience includes:

  • Developers building financial applications
  • Fintech teams integrating market data into products
  • Trading tool providers
  • Dashboard and analytics platforms
  • Quantitative research teams
  • Backtesting and data science workflows
  • Enterprise data teams that need API-based market data delivery

SiftingIO is especially useful for teams that need both real-time and historical data, or teams that work across multiple asset classes and want a consistent API model instead of separate vendor-specific integrations.

What's the story behind your product?

SiftingIO's answer

SiftingIO was created from hands-on experience building and operating financial data infrastructure.

Market data integrations often become more complex as products grow. Each asset class can come with different data formats, different delivery methods, different authentication models, and different assumptions about symbols, timestamps, quotes, trades, and history.

SiftingIO was built to reduce that complexity.

The goal is to provide a consistent market data API that helps teams access real-time and historical data across multiple asset classes without rebuilding their integration every time they add a new market.

The product reflects an engineering-first approach: clean API design, unified schemas, REST and WebSocket support, multi-venue aggregation, and infrastructure that can support production financial workflows.

Who are some of the biggest customers of your product?

SiftingIO's answer

SiftingIO does not publicly list customer names unless they are approved for disclosure.

The platform is designed for financial applications, trading tools, dashboards, research platforms, quantitative teams, fintech companies, and enterprise data workflows that need real-time or historical market data through APIs.
