Pick PostHog if you're an engineering-led team that wants analytics, session replay, feature flags and experiments from one install, with autocapture and access from your code editor. Pick Mixpanel if you want a focused analytics product that product and business people can use on their own. Both state a free plan, so you can start either without a sales call.
Is analytics the whole job, or one slice of a bigger data problem?
Answer that before you look at a single chart. If all you want is to see how people move through your product, which features they use and where they drop off, you're shopping for analytics. If you also want error tracking, session recordings, feature flags, surveys and SQL in the same place, you're shopping for something wider. These two sit on different sides of that line, even though they're usually lumped together.
Straight advice for busy product teams
Engineering-led teams who'd rather install one thing and get analytics, replays, flags, experiments and errors together should start with the bundle from the developer side. Teams where product managers, marketers and founders want to answer their own questions about user behaviour, without asking an engineer, should start with the focused analytics product. Neither site makes a convincing case for an overall winner, and since both state a free plan, the quickest way to decide is to install both on a test project.
One of them wants to replace a stack of tools
This is the part most comparisons miss. The engineer-led product doesn't really sell itself as an analytics tool any more. The vendor describes a single place to ingest, store and query product and company data, with replays, errors and logs stitched together, and pitches it as a context layer that AI agents can query as well as people. So it's competing with your error tracker, your feature flag tool and your survey tool as much as with any analytics product.
The other side has moved too. Its old product analytics address now returns a not-found page and the home page sits at a new path, a sign the site was reorganised around AI. Both now lead with AI agents rather than dashboards. If your picture of either one comes from a few years ago, it's out of date.
Six differences laid out

| Getting started | Free to start, no credit card needed, per its home page | A Get Started Free button on every page |
How the day-to-day work differs
Getting data in
Autocapture is the big convenience on the engineer-led side. It records pageviews, clicks and form submissions without you writing tracking code for each event, and setup runs through a command-line wizard or an AI prompt. That's handy when you're moving fast and don't yet know which events you'll care about.
The focused product talks less about installation and more about what happens once data's flowing: real-time, self-serve insight for everyone on the team. Its site doesn't show a developer install wizard.
Asking questions
If your developers live in Cursor, Claude Code or VS Code, the bundle lets them query data from there through MCP, and its AI assistant can pull answers from analytics alongside other sources such as Stripe and GitHub in the demo. The analytics-first product goes the other way: its agents watch your product continuously and surface insights before you ask, according to the vendor.
Trusting the numbers
Data trust gets its own features on the analytics-first side. It lists AI Data Governance, a Context Engine and Verified Mode, all aimed at making sure AI answers come from data you'd stand behind. The bundle's pitch is that keeping everything in one store, stitched together, means fewer gaps between tools. Both are reasonable answers to the same worry.
Signs you've picked the wrong one
- You chose the bundle, but nobody on your team writes code and the people asking questions find it too technical.
- You chose the focused product, then found yourself also buying separate tools for feature flags, surveys and error tracking.
- You wanted session replay most of all. Both list it, so this one shouldn't decide things for you.
- You're relying on AI answers but haven't checked how either tool decides which data it trusts.
For a wider look at this category, our guide to product analytics tools covers more options, and the Amplitude comparison is worth reading if the focused analytics route appeals.

Frequently asked questions
Does PostHog or Mixpanel have a free plan?
Both state a free plan. One says you can get started free with no credit card needed, and the other has a Get Started Free button across its site.
Which one is easier for non-technical teams?
The analytics-first product is built around self-serve insight for the whole team. The bundle names product engineers, PMs, growth engineers and founders, and its setup leans technical.
Can I replace my error tracking and feature flag tools with one of these?
The engineer-led bundle lists error tracking, feature flags, surveys and SQL alongside analytics. The focused product lists analytics, session replay, experiments and metric trees, so you'd likely keep those other tools.
Do both offer session replay?
Yes, both list session replay, so it shouldn't be the deciding factor.
Do I need to tag every event myself?
Not with autocapture on the bundle, which records pageviews, clicks and form submissions without extra code. The other site doesn't state an equivalent feature.
