OakData vs PostHog
PostHog is a platform. OakData is a point of view.
PostHog ships a dozen developer products in one. OakData does one thing, person-level web analytics, and polishes it until it's the best on the planet.
PostHog is the closest product to OakData in capability. It also has session replay, funnels, autocapture, and person profiles, plus a lot OakData doesn't attempt: feature flags, A/B experiments, surveys, and a data warehouse. It's open source, developer-first, and priced per product on generous usage tiers. If you want an all-in-one developer data platform, PostHog is the strongest candidate there is.
OakData's bet is focus. One product, one dashboard, every feature at every tier: identity that survives cleared cookies, revenue attribution to first touch, bot filtering with network-level signals, heatmaps over real page snapshots, and an MCP server so your agent works your analytics. There's no product matrix to configure and no per-product billing to model. And the dashboard is designed to be read in seconds rather than queried.

Choose OakData if…
- You want every feature at every tier with one simple usage-based price. No per-product billing to model.
- Identity accuracy matters. OakData's fingerprint survives cleared cookies and incognito, where storage-based identity resets.
- You want revenue, bot filtering, and company reveal built in rather than assembled from warehouse sources and queries.
- You prefer a dashboard your whole team reads at a glance over a query surface built for analysts.
Choose PostHog if…
- You need feature flags, A/B experiments, or surveys in the same platform as your analytics.
- You want SQL access to raw events or a built-in data warehouse.
- Open source or self-hosting is a requirement.
Questions
Scope and philosophy. PostHog is a platform of many developer products (analytics, flags, experiments, warehouse), each priced separately. OakData is one focused product: person-level web analytics with replay, funnels, revenue, and identity, every feature included at every tier.
No. OakData deliberately doesn't do flags, experiments, or surveys. That's PostHog's territory. If those are must-haves in the same tool as analytics, PostHog is the honest recommendation.
That's the intent. One snippet, one dashboard, one price covering everything, versus choosing products, tiers, and per-product usage budgets. Teams that mostly need to understand their visitors tend to be productive in OakData immediately.
OakData layers a hardware-derived fingerprint under standard identifiers, so identity survives cleared storage, incognito, and browser swaps. Storage-based identity, which PostHog uses like most tools, resets when the browser data does.
