PostHog vs Mixpanel: which should you use in 2026?
Updated
Key takeaways: PostHog vs Mixpanel
Pick PostHog if…
- Your engineers own analytics and want one tool for events, replay, flags, A/B tests, surveys and error tracking.
- You need to see the source or self-host (PostHog is MIT-licensed; self-hosting is free but officially unsupported).
- You expect 2–10M events a month and want the lower list price — about $103/mo at 5M anonymous events versus a much higher Mixpanel list rate.
- You want SQL over your events and a built-in data warehouse.
Pick Mixpanel if…
- Product managers and analysts are the main users and need answers without writing SQL.
- You want best-in-class funnels, flows, retention and cohort reports with a gentle learning curve.
- You already have data in Snowflake, BigQuery, Databricks or Redshift — Mixpanel's warehouse connectors are free on paid event plans.
- You qualify for the startup program (first year free for companies under five years old with up to $8M raised).

PostHog vs Mixpanel for privacy and GDPR
Both tools collect personal data by default — they're built to follow identified users over time — so under GDPR and the ePrivacy Directive you'll normally need consent before setting their cookies, plus a data processing agreement (both offer one).
PostHog gives you more knobs. Its JavaScript SDK supports cookieless_mode ("always" or "on_reject"), which counts users with a privacy-preserving hash computed on PostHog's servers — useful if you want anonymous counts from visitors who decline cookies. In that mode you shouldn't call identify(). On PostHog's EU Cloud (Frankfurt), IP capture is off by default for new projects. Because PostHog is open source, you can also self-host and keep data entirely on your own infrastructure, though PostHog calls self-hosting officially unsupported.
Mixpanel's SDK sets a first-party cookie by default and can switch to localStorage, but it doesn't document a cookieless mode. It does offer opt_out_tracking_by_default for consent-first setups, IP-based geolocation can be turned off, and EU and India data residency are available. One gotcha: residency is chosen when you create a project, and Mixpanel says it can't migrate an existing project to a different region — pick the EU before you send data.
PostHog vs Mixpanel pricing at three traffic levels
Both have a generous free tier of 1M events a month, so small products pay nothing. The gap opens above that. PostHog publishes graduated per-event rates; Mixpanel publishes a list overage rate and discounts prepaid volume. Figures below are monthly list prices for product analytics events only, as of October 2026.
| Monthly traffic | 1M events/mo | 5M events/mo | 10M events/mo |
|---|---|---|---|
| PostHog | 1M events/mo: $0 (free tier) | 5M events/mo: ≈ $103 (anonymous events) | 10M events/mo: ≈ $324 (anonymous events) |
| Mixpanel | 1M events/mo: $0 (free tier) | 5M events/mo: Up to ≈ $1,120 at list rate | 10M events/mo: Up to ≈ $2,520 at list rate |
PostHog numbers are computed from its published graduated rates; identified events (with person profiles) cost extra — roughly $1,080/mo at 10M. Mixpanel numbers are the $0.00028 list overage rate applied above the free 1M; Mixpanel says prepaid volumes get lower rates, so a real quote is usually lower. Session replay is billed separately on both.
Which is easier to set up: PostHog or Mixpanel?
Both install with a JavaScript snippet or an SDK (web, iOS, Android, React Native, server libraries) and both offer autocapture, so you see clicks and pageviews within minutes. The real work is the same for both: defining a tracking plan — the 20–50 named events and properties your team will actually query — and calling identify() when users log in.
Where they differ is after install. PostHog's surface is large (analytics, replay, flags, experiments, surveys, warehouse, error tracking, LLM analytics), and the fastest way to answer non-standard questions is often its SQL editor. Mixpanel is narrower and more guided: Insights, Funnels, Flows and Retention reports are designed for non-technical teammates, which is why PMs tend to ramp faster on it.
Who each one is for
PostHog suits developer-led startups and product engineers who'd rather run one platform than stitch together analytics, LaunchDarkly-style flags, Hotjar-style replay and a survey tool. It rewards teams comfortable with SQL and usage-based billing across several meters.
Mixpanel suits product, growth and data teams at companies where analysts and PMs run the reports, and at mid-size or larger companies with a warehouse they want to analyze in place. It's also a common choice when the main question is "where do users drop off and who comes back?" rather than "which build should we ship?".
Migrating between Mixpanel and PostHog
PostHog has a managed migration that connects straight to Mixpanel with API credentials (or imports from S3/GCS). Imports are free but require a paid PostHog plan, and each direct job covers at most one year of data — PostHog recommends the S3 route for reliability on bigger histories.
Going the other way, Mixpanel's Import API and warehouse connectors accept historical events. In both directions, plan to re-create dashboards, cohorts and saved reports by hand; event names usually carry over, but report definitions don't.
A third option: VisitTrack
Disclosure: VisitTrack publishes this page.
If what you actually need is website traffic and "which channel brought paying customers" rather than in-app product analytics, both tools are heavier than necessary. VisitTrack is a privacy-first web analytics tool with a cookieless mode and built-in revenue attribution from Stripe, Paddle, Lemon Squeezy, Polar and Razorpay, plus funnels, goals and custom events. It's priced by events from $5/mo with every feature on every plan. It's not a replacement for PostHog's feature flags or Mixpanel's cohort analysis — it answers the marketing-side question.
PostHog vs Mixpanel: frequently asked questions
Is PostHog cheaper than Mixpanel?
At list prices, yes, above the free tier. Both include 1M events a month free; at 10M anonymous events PostHog works out to about $324/mo, while Mixpanel's $0.00028 list overage rate implies up to about $2,520/mo before the volume discounts Mixpanel applies to prepaid plans. Get a Mixpanel quote before deciding.
Is PostHog open source?
Yes. PostHog's code is MIT-licensed and you can self-host it for free, but PostHog says self-hosted deployments are officially unsupported and paid-plan features are Cloud-only. Mixpanel is not open source and can't be self-hosted.
Does Mixpanel have session replay like PostHog?
Yes. Mixpanel includes 10,000 session replays a month on its free plan and up to 500,000 on Growth, alongside heatmaps. PostHog includes 5,000 recordings a month free and bills per recording after that.
Can I host PostHog or Mixpanel in the EU?
Both offer EU hosting. PostHog has an EU Cloud in Frankfurt; Mixpanel offers EU data residency that must be selected when the project is created, because it can't move an existing project later.
Can I migrate from Mixpanel to PostHog?
Yes — PostHog's managed migration connects directly to Mixpanel with API credentials, or imports from S3. It's free on paid PostHog plans, covers up to a year per direct job, and you'll rebuild dashboards manually.
Do PostHog and Mixpanel need a cookie banner?
Usually, yes. Both set identifiers by default, so in the EU you'd ask for consent first. PostHog's cookieless mode can count visitors without cookies; Mixpanel documents opt-out and localStorage persistence but not a cookieless mode.
Which is better for non-technical teams?
Mixpanel. Its report builders are designed for product managers and marketers, while PostHog's breadth and SQL-first workflows suit engineers best.
