Features and specs

What each product offers, as listed by its team.

WTM API 6 features
Cozystack 5 features
  • HTML to Markdown Conversion
    Convert any webpage to clean, structured Markdown with a single POST request. Headings, bold, italic, links, and images all preserved.
  • Table Preservation
    HTML tables are converted to proper Markdown tables, keeping data structured and readable.
  • Code Block Detection
    Code blocks are preserved with syntax language hints. Perfect for extracting documentation and tutorials.
  • Absolute URL Resolution
    All relative links and image URLs are automatically resolved to absolute URLs based on the source page.
  • Sub-Second Response
    Average response time under 1 second. Server-side HTML parsing with Cheerio — no headless browser overhead.
  • Live Demo
    Try the API directly on the website. 3 free conversions without signing up. Paste any URL and see the Markdown output instantly.
  • 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.

Analysis

An editorial look at what each product does well and who it suits.

WTM API
Cozystack

Overall verdict

  • WTM API appears to be a niche data/API service, but without verified, independent, up-to-date information confirming its reliability, uptime, pricing transparency, or customer support quality, it's not possible to give a confident endorsement. Prospective users should conduct due diligence, test the API with a trial or sandbox account, and verify documentation quality and support responsiveness before committing.

Why this product is good

  • Limited independent reviews or third-party benchmarks are readily available to verify claims of performance and reliability.
  • Pricing and feature transparency should be confirmed directly on their site since public information is sparse.
  • API-based services can vary widely in documentation quality, so checking their developer docs firsthand is essential.
  • Support responsiveness and SLA guarantees are not well-documented externally, so direct testing is recommended.

Recommended for

  • Developers who are willing to test the API firsthand via a trial before committing.
  • Businesses needing a specific niche data feed that WTM API claims to provide, provided they verify data accuracy first.
  • Technical teams comfortable evaluating API uptime and documentation quality independently.
  • Not recommended for mission-critical production use without a thorough vetting period.

Overall verdict

  • Cozystack is a solid choice for teams wanting a free, open-source PaaS built on Kubernetes, Kubevirt, and Flux, offering a self-hosted alternative to public cloud platforms with strong automation and GitOps principles baked in.

Why this product is good

  • Fully open-source and free, avoiding vendor lock-in and licensing costs
  • Built on proven CNCF technologies like Kubernetes, KubeVirt, and Flux CD
  • Provides a unified platform for both containers and virtual machines
  • Enables self-service infrastructure provisioning similar to major cloud providers
  • Strong GitOps-native approach simplifies deployment consistency and rollback
  • Active development backed by a community and commercial support options
  • Reduces operational overhead by automating cluster and tenant management

Recommended for

  • Organizations wanting to build an internal private cloud platform
  • DevOps teams already invested in Kubernetes and GitOps workflows
  • Companies seeking to reduce reliance on public cloud providers
  • Managed service providers offering PaaS/IaaS to clients
  • Teams needing both VM and container workloads unified under one platform
  • Cost-conscious enterprises looking for open-source cloud infrastructure alternatives

Questions & Answers

As answered by people managing WTM API and Cozystack.

What makes your product unique?

WTM API's answer

WTM API focuses on structure preservation, not just text extraction. Unlike most scrapers that return raw text, it converts HTML to proper Markdown with headings, tables, code blocks, and links intact. No headless browser needed — pure server-side parsing means sub-second responses at a fraction of the cost.

Why should a person choose your product over its competitors?

WTM API's answer

Speed and simplicity. One POST call, any URL, clean Markdown back in under 1 second. No SDKs to install, no headless browser to maintain, no complex configuration. Generous free tier (50 calls/month) and straightforward pricing. The output is immediately usable for LLMs, RAG pipelines, or content migration.

How would you describe the primary audience of your product?

WTM API's answer

Developers building AI/LLM applications, RAG pipelines, content migration tools, or any system that needs web content in a structured, portable format. Also useful for teams moving content to Markdown-based platforms like Notion, Obsidian, or static site generators.

What's the story behind your product?

WTM API's answer

I was building a RAG pipeline and needed web content in Markdown format. Existing tools gave me either raw text (losing all structure) or required a headless browser (slow and expensive). I built WTM API to solve my own problem - a fast, simple API that preserves the structure of any webpage as clean Markdown. Shipped the MVP in a weekend using Next.js, Supabase, Stripe, and Vercel, all on free tiers.

Which are the primary technologies used for building your product?

WTM API's answer

Next.js 16 (App Router), Supabase (auth and PostgreSQL), Stripe (subscription billing), Vercel (hosting), and Cheerio (server-side HTML parsing). The entire stack runs on free tiers with zero monthly infrastructure cost.

Who are some of the biggest customers of your product?

WTM API's answer

  • Early-stage AI startups building RAG pipelines
  • Independent developers working on content tools
  • Currently in public beta and growing the user base
