About Blazeway.app and Cozystack

In their own words, as submitted to SaaSHub.

Cozystack

Blazeway is the experiment journal for solo founders. Most founders already track A/B tests somewhere. A Notion page, a Google Sheet, a Linear ticket. The page works for the first ten tests. By test fifteen, finding past insights costs more than running a new test from scratch. Blazeway is the...

Features and specs

What each product offers, as listed by its team.

Blazeway.app 7 features
Cozystack 5 features
  • Structured hypothesis capture
    Forces clarity before the test runs. You commit to what you expect and why, so the result actually teaches you something instead of just declaring a winner.
  • Permanent decision timeline
    Every test stays findable years later. No more rerunning the same experiment because the Notion page got buried in test fourteen.
  • Cookieless server-side variant assignment
    Run tests in the EU without a consent banner, without losing 40% of your visitors to "Reject all", and without a legal review.
  • One-click LLM export
    Hand your full experiment history to ChatGPT or Claude as a single optimized prompt and get cross-test patterns a human reader would miss.
  • Insight log on every closed test
    The learning is captured at the moment it's freshest. Six months later you remember the insight, not just the conversion lift.
  • Public profile for your experiments (optional)
    Share your decision timeline as a personal page. Building in public, without a separate blog to maintain.
  • Built for one person, not a growth team
    No seats, no roles, no Jira-style workflows. The tool is the size of the problem a solo founder actually has.
  • 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.

Overall verdict

  • Blazeway.app is not a widely established or recognized product/service, and there is limited verifiable public information available about its features, pricing, reliability, or user reviews. Without substantial evidence of a proven track record, it should be approached with caution and thoroughly researched before use.

Why this product is good

  • Limited public information or reviews available to verify claims of quality or performance
  • Unclear how long the service has been operating or its track record
  • Unknown security practices, data handling policies, or compliance certifications

  • Uncertainty around customer support quality and responsiveness

Recommended for

  • Early adopters willing to test new or niche tools with inherent risk
  • Users who conduct their own due diligence before committing to unverified platforms
  • Those seeking non-critical, low-stakes applications where potential issues would have minimal impact
  • Individuals who can verify the platform's legitimacy through direct contact with the provider

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

Questions & Answers

As answered by people managing Blazeway.app and Cozystack.

What makes your product unique?

Blazeway.app's answer

The A/B testing market has spent ten years optimizing the wrong half of the problem. Bigger statistics engines, finer-grained dashboards, more event volume. Every tool assumes that more data leads to better decisions. None of them help a founder remember what they actually learned six months ago.

Blazeway is an experiment journal. Every test starts with a four-part hypothesis (Observation, Mechanism, Prediction, Success Threshold) and ends with a written insight that joins a permanent decision timeline. A founder with twenty documented insights makes better product decisions than one sitting on two million events and no record of what they tried.

The cookieless A/B test runner is built in so the journal stays the source of truth. The category is compounding knowledge: each test makes the next one smarter. PostHog cannot sell "less data, more learning". Optimizely cannot retire its statistics engine. The journal-first stance is structurally ours.

Why should a person choose your product over its competitors?

Blazeway.app's answer

Most founders already document their experiments somewhere. A Notion page, a Google Sheet, a Linear ticket. The page works for the first ten tests, then collapses under its own weight by test fifteen. Meanwhile the actual A/B testing platforms (Optimizely, VWO, Convert, GrowthBook, PostHog) are priced for growth teams and treat the test result as the deliverable. The documented learning is left as homework.

Blazeway closes both gaps in one place:

  • Hypothesis wizard forces clarity before the test starts
  • Insight log captures the learning when it ends
  • Decision timeline keeps every past test searchable years later
  • One-click LLM export turns your full history into a single optimized prompt
  • Cookieless A/B runner included so EU founders skip the consent banner entirely

How would you describe the primary audience of your product?

Blazeway.app's answer

Solo founders, indie hackers, and bootstrapped small teams shipping their own product. People running two to ten experiments a year who want every test to teach them something they can find again next quarter.

The audience skews EU and privacy-conscious. The cookieless architecture removes the GDPR cost: no consent banner, no legal review, no cookie modal eating 40% of visitors before the test even starts.

Not the right fit: growth teams at large companies, agencies running tests for clients, anyone who needs feature flags as a primary product. Those use cases are well served by Statsig, GrowthBook, or PostHog.

What's the story behind your product?

Blazeway.app's answer

Blazeway started as a tool the founder needed for his own work. After running A/B tests across several side projects and watching every documented insight disappear into stale Notion pages, the question became: what if the test runner and the decision journal were the same product?

The first version shipped in early 2026, built by a single solo founder, in public, on weekends and evenings, under the handle @deliverhonestly. Every weekly build log, every closed experiment, every learning is shared openly. The product is built the way it teaches its users to build: hypothesis, test, insight, repeat.

Which are the primary technologies used for building your product?

Blazeway.app's answer

App (app.blazeway.app) React, TypeScript, Vite, Tailwind CSS, shadcn/ui, Bun

Backend Supabase: Postgres, Auth, Edge Functions for cookieless server-side variant assignment
