About PostHog and Blazeway.app

In their own words, as submitted to SaaSHub.

PostHog

For developers just starting out, PostHog is a free way to understand how your product is being used, without having to send any data to 3rd parties. For enterprise customers, one data security becomes a key concern, or B2C businesses where using a SaaS solution is unaffordable, it's typical to...

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...

Possible disadvantages

  • Resource Intensive for Self-Hosting
    Self-hosting PostHog can be resource-intensive, requiring significant server capacity and management effort.
  • Complex Setup
    The initial setup, especially for self-hosting, can be complex and may require a good understanding of Docker and Kubernetes.
  • Learning Curve
    Due to its extensive features and capabilities, there can be a steep learning curve for new users or teams to fully leverage PostHog's capabilities.
  • Limited Pre-Made Integrations
    While it supports custom integrations, the number of pre-made integrations is limited compared to some commercial analytics platforms.
  • Cost for Additional Features
    Advanced features and enterprise-level support come at a premium, which might be costly for smaller companies or startups.
  • Less Mature Community and Documentation
    Compared to established analytics platforms, PostHog's community and documentation are still growing, which might limit available resources and support.
  • 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.

Recommended for

    PostHog is particularly well-suited for product teams, developers, and startups that require deep insights into user interactions and need the flexibility of a self-hosted solution. It is also a good fit for organizations that prioritize data privacy and want to maintain full control over their data.

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
  • No widespread user testimonials or third-party evaluations to reference
  • 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

Questions & Answers

As answered by people managing PostHog and Blazeway.app.

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

Landing page (www.blazeway.app) Astro with prerendered static HTML, hosted on Netlify

Public profiles (www.blazeway.app/@handle) Astro SSR on Netlify with React 19 islands. Shared Supabase session via subdomain cookie. Markdown rendered through marked + rehype-sanitize. Editorial Fraunces theme distinct from the app.

Tracking snippet Vanilla TypeScript. Under 2KB. No third-party dependencies, no cookies, no localStorage.
