MIRA FIVE is a PostHog alternative for a narrower job. It is analytics built around the person and organised for marketing: where people come from, how they move, what they do and what they want, with A/B tests and feature flags on the same script. ## Who is each tool for? PostHog suits product and engineering teams that want many tools on one event stream and are comfortable building the views they need. Its free tier covers 1 million analytics events, 5,000 session recordings and 1 million feature flag requests a month. MIRA FIVE suits founders and marketing leads who pay for ads and want the answer ready: which channel brings the customers who pay? The Overview opens with people, new people, buyers and revenue, and Acquisition shows buyers for nine channels, AI assistants among them. ## Which channel brings the customers who pay? In MIRA FIVE this is the first screen. Buyers and revenue sit beside every channel and campaign, and each buyer opens into a page with every visit. The Google Ads connection imports daily spend per campaign, joined by utm\_campaign or gclid, for cost per buyer and ROAS. PostHog can answer it too, with more assembly. Its marketing analytics connects Google Ads, Meta, LinkedIn, TikTok and other networks and shows cost per conversion; its revenue analytics reads Stripe and other billing sources. Both are marked beta. ## When PostHog is the better choice Choose PostHog if you want session replay, surveys, error tracking or a data warehouse beside your analytics, or if its free tier covers your volume. Choose it for spend from Meta and other ad networks today, or to run the MIT-licensed code yourself. MIRA FIVE is a hosted service, credits first or last touch, and has no replay or surveys. ## Where is the data hosted? PostHog offers a US cloud and an EU cloud hosted in Frankfurt. MIRA FIVE is run by Cloo GmbH in Auerbach and hosted in Germany; analytics data is stored and processed in Germany. A new MIRA FIVE website source sets no cookies and stores nothing on the device; people, experiments and per-visitor flags need a Full website source and a visitor’s consent, or a server. Compliance depends on what is collected and why, and hosting is one part of that. ## Running both Keep PostHog for product work and add the MIRA FIVE script for acquisition and buyers.
