Product analytics is one line here, not the whole map.
PostHog is an excellent product-analytics platform. AZ-Five runs the same seven capabilities — events, funnels, replay, flags, experiments, surveys, logs — as one line of a six-line network that also carries your BI, data quality, pipelines and model monitoring.
Where PostHog is stronger.
A comparison you can trust has to start with what the other side does better.
- Self-hosting, today
- PostHog is open source and can be self-hosted right now. AZ-Five is hosted; self-hosting is planned but not shipped.
- Ecosystem and community
- Years of public development, a large plugin and integration surface, and an enormous user community.
- Depth in replay and heatmaps
- PostHog’s session replay, heatmaps and autocapture tooling are mature and battle-tested at very large scale.

What the network adds.
- One set of tables
- Your funnels and your revenue dashboard resolve the same governed measures — no export from the analytics silo into the BI tool. See the line
- Quality attached to numbers
- A malformed event is caught by the tracking plan at ingestion, and every published number carries the health of the data behind it. See the line

Is AZ-Five a PostHog alternative?
For the product-analytics stack — events, funnels, session replay, feature flags, experiments, surveys — yes: AZ-Five ships the same capabilities. The difference is scope: in AZ-Five they run on the same governed tables as your BI, data quality and pipelines, instead of in a separate analytics silo.
Can I self-host AZ-Five like PostHog?
Not yet. AZ-Five is hosted and operated for you; self-hosting is planned but not shipped, and we say so plainly. What is open today is the data: tables are standard Parquet with a Delta Lake transaction log you can copy out at any time.
How does pricing compare?
Both are usage-based with a free tier. AZ-Five’s free tier includes every feature with unlimited seats — experiments, replay, embeds and pipelines are never gated behind a plan; paid tiers buy volume, retention and query priority.
Do I lose replay, flags or experiments by choosing AZ-Five?
No — session replay, server-evaluated feature flags and Bayesian A/B experiments all ship in AZ-Five, on every tier, with eight capture SDKs. PostHog’s replay tooling is more mature; AZ-Five’s runs on the same tables as everything else.
