Also searched as Matomo vs PostHog — same comparison, one verdict.
PostHog and Matomo are closely matched on ownership (85 vs 92) — this one comes down to pricing and to which trade-offs below you can live with.
PostHog
TOP PICKProduct analytics, session replay, flags and experiments in one self-hostable product.
PostHog is the most complete answer here because it collapses several line items into one: product analytics, session replay, feature flags, A/B testing, surveys and a data warehouse, all in a product you can run on your own infrastructure. For teams currently paying Amplitude for analytics and LaunchDarkly for flags, that consolidation is often the real saving rather than any single rate. Around 37.4k stars and pushed to daily. The licence needs stating precisely: the core is MIT, but the `ee/` directory is licensed separately as enterprise — so it is MIT-with-a-carve-out rather than plain MIT, which is how it is usually described.
Matomo
GPL analytics you host yourself — the compliance answer.
Matomo is the veteran of privacy-respecting analytics: GPL-3.0, self-hosted, with 100% data ownership, no sampling, and configurations that let it run without cookie consent in many jurisdictions. Around 21.7k stars and well over a decade of continuous development. It leans web analytics rather than product analytics — sessions, sources, campaigns, goals — with product-style funnels and cohorts available as paid plugins. If the reason you are on this page is a legal or procurement requirement rather than a product question, Matomo is usually the shortest route to a yes.

PostHog is Macrostack's recommended Amplitude alternative, so it's our pick here.
PostHog
Strengths
- +Replaces analytics, session replay, flags and experiments with one tool
- +Self-hostable, so behavioural data never leaves your infrastructure
- +Autocapture means useful data before anyone writes a tracking plan
- +Very generous free tier if you would rather use the hosted version
Trade-offs
- −Self-hosting at volume means operating ClickHouse — a real commitment
- −The `ee/` directory is not MIT despite the project's reputation
- −Heavier and more complex than a focused analytics tool
- −Analysis depth still trails Amplitude for sophisticated cohort work
Matomo
Strengths
- +Full data ownership with a mature, well-trodden self-host path
- +Can be configured to run without cookie consent in many jurisdictions
- +No sampling — the numbers are the numbers
- +Over a decade of development and a large plugin ecosystem
Trade-offs
- −Web analytics first; product analytics needs paid plugins
- −Interface feels dated next to PostHog and Amplitude
- −PHP and MySQL need tuning at high traffic
- −Several of the features people expect are premium add-ons
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose PostHog
if replaces analytics, session replay, flags and experiments with one tool.
Choose Matomo
if a lower exit cost matters more to you than any single feature, and full data ownership with a mature, well-trodden self-host path.
Neither, yet
if both carry a real cost you should weigh first — self-hosting at volume means operating ClickHouse — a real commitment, and web analytics first; product analytics needs paid plugins. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
What it takes to run these yourself
Real requirements and honest running costs, not the vendor quickstart.
PostHog vs Matomo — common questions
Is PostHog a better fit than Matomo for product analytics?
It depends on what you are optimising for, and the honest split is this: Matomo scores 92 to PostHog's 85 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. PostHog earns its place on a different axis — replaces analytics, session replay, flags and experiments with one tool. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
PostHog keeps its data local or in open formats, so leaving is an export rather than a negotiation. Matomo is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host PostHog or Matomo?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are PostHog and Matomo both alternatives to Amplitude?
Yes — both appear in our Amplitude comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Amplitude and now choosing between the two replacements, which is a narrower and much easier question.
