Is it actually a replacement?
We have written a verdict on what it replaces — what you lose, and why people still pay:
How PostHog runs
Where it runs
PostHog runs on your machine or their cloud.
Installing it
Create a PostHog Cloud project or use the hobby self-host script on a Linux server.
Where your data lives
The self-hosted stack splits analytics, transactions, queues and recordings across ClickHouse, PostgreSQL, Kafka, Redis and object storage; cloud data lives in PostHog's managed regions.
What setup takes
None for hosted signup; self-hosting is an unsupported, resource-heavy multi-service stack requiring serious operations work.
The catch compared with Amplitude
Its kitchen-sink product is heavier, while Amplitude's core product-analytics workflows and governance are more refined.
PostHog questions
Is PostHog open source?
Yes — it is released under MIT (+EE).
Can PostHog replace Mixpanel?
Our verdict on Mixpanel is YES. Umami (38k stars), PostHog (38k stars), Plausible (23k stars) are mature open-source replacements for Mixpanel — self-host with docker and stop paying.
Can I self-host PostHog?
Yes — we rate it hard to self-host, and it runs on your machine or their cloud. Create a PostHog Cloud project or use the hobby self-host script on a Linux server.
