# PostHog vs Mixpanel vs Amplitude: Product Analytics in 2026

In 2026 all three give away session replay, feature flags and experiments on their free plans. The feature checklist stopped separating them. What still does is **how each one bills you** and **who on your team is supposed to open it**. We compare PostHog, Mixpanel and Amplitude on both, price them at 1M, 5M and 10M events, and say when a simpler tool is the better answer.

## First: what product analytics is for

Page-view analytics tells you how many people arrived. It cannot tell you whether they ever reached the moment your product became useful to them, which feature the ones who stayed had in common, or at which step of onboarding the trials quietly die. Those are the questions that decide whether a SaaS grows, and they are about _users doing things inside your app_, not visitors reading pages.

Product analytics records those actions as events tied to a user, then lets you slice them into funnels, retention curves and cohorts. Without it, product decisions are made by whoever argues most confidently in the meeting.

### Find your activation moment

The action that, once a user does it, makes them far more likely to stay. Every onboarding change should push people towards it, and you cannot see it without event data.

### See where the funnel leaks

Sign-up to first project to invited teammate to paid. A funnel chart shows which step loses the most people, so you fix the step that matters instead of the one that is loudest.

### Know whether a release worked

Ship behind a feature flag, compare the group that got it with the group that did not. That turns "the redesign feels better" into a number.

### Watch what numbers cannot show

Session replay shows the user rage-clicking a disabled button. All three tools now include it, so a drop in a funnel links straight to recordings of the people who dropped.

**What it does not do:** it does not tell you _why_. A funnel shows that 60% leave at step three; only talking to users tells you what they were thinking. And it is only as good as your tracking plan — inconsistent event names make every chart quietly wrong, and no tool on this page fixes that for you.

**Do you need this yet?** Before launch, or with a few dozen users, no — you can talk to every one of them, and a web analytics script is enough. Product analytics starts paying off once you have more users than you can personally interview, usually somewhere past a few hundred weekly actives.

## Quick Verdict

![](https://www.google.com/s2/favicons?domain=posthog.com&sz=128)PostHog

The all-in-one built for engineers. Analytics, replay, flags, experiments, error tracking, surveys and a data warehouse in one product, each with its own monthly free allowance and a per-unit price after.

Widest bundleLowest per-event rate

![](https://www.google.com/s2/favicons?domain=mixpanel.com&sz=128)Mixpanel

The fastest path from question to chart for a product manager. Clean, opinionated reports, and in 2026 experiments and feature flags moved onto the Free and Growth plans.

Shortest learning curvePricier per event

![](https://www.google.com/s2/favicons?domain=amplitude.com&sz=128)Amplitude

The analyst's platform. Deepest behavioural analysis, governance and warehouse connections, and the biggest free allowance at 2M events — with custom-quoted pricing once you outgrow it.

2M events freeBuilt for analysts

TL;DR

No single winner — pick on who uses it. Engineers who want one tool and one bill → **PostHog**. PMs who want answers without learning a query model → **Mixpanel**. A data team with governance needs and a warehouse → **Amplitude**. And if all you need is traffic numbers, none of these — use **Plausible** or **Umami**.

## The two questions that actually separate them

Put the three feature pages side by side and they read almost identically in 2026\. Two things are still genuinely different, and between them they decide both your bill and whether your team uses the tool at all.

### 1\. What is the meter?

**PostHog** meters every product separately — events for analytics, recordings for replay, requests for flags, exceptions for error tracking — each with its own free allowance and a per-unit price that falls with volume. **Mixpanel** meters events on the Growth plan. **Amplitude** uses events on its free plan and a mix of events and monthly tracked users (MTUs) on paid plans, with Growth and Enterprise quoted by sales. An event-heavy product with few users and a light product with many users can land on opposite sides of this.

### 2\. Who is the daily user?

PostHog assumes the person reading the chart also wrote the tracking code, and rewards that with SQL access and one SDK for everything. Mixpanel assumes a product manager who wants a funnel in thirty seconds without help. Amplitude assumes an analyst or a data team who wants governance, a taxonomy and a warehouse on the other end. A tool bought for the wrong person does not get opened.

A useful test: picture the person who will open the tool on a Monday morning without being asked. Choose for them, not for whoever is running the evaluation.

## The three, in detail

Allowances and list prices as published on each vendor's pricing page in September 2026\. Annual contracts and volume discounts change the paid numbers, especially for Mixpanel and Amplitude.

### PostHog

Every product tool, one bill

$0 up to 1M events

then from $0.00005/event, falling with volume

* Free every month: 1M events, 5K replays, 1M flag requests
* Also free: 100K exceptions, 1,500 survey responses, 1M warehouse rows
* 2M–15M events billed at $0.0000343 each
* SQL access to your own events, plus a built-in data warehouse
* Open-source codebase with a self-hosted hobby option
* Unlimited seats on every plan
* CaveatEach product is metered separately, so a bill that starts with analytics can grow as you switch on replay, flags and error tracking. Set a billing limit per product from day one.

Best for: Engineering-led teams who would rather run one tool than stitch five together.

Flags + experiments now free

### Mixpanel

Answers without a query language

$0 up to 1M events

Growth lists at $0.28 per 1,000 events

* Free: 1M events and 10K session replays a month
* Experiments and feature flags included on Free and Growth in 2026
* Growth covers up to 20M events and 500K replays
* Funnels, retention and flows are fast to build without training
* Unlimited seats on the free plan
* CaveatAt list price it is the most expensive per event of the three — roughly $2,520 a month at 10M events. Group analytics and data pipelines are paid add-ons.

Best for: Product-manager-led teams who want self-serve answers and will pay for the speed.

Largest free allowance

### Amplitude

Depth and governance for data teams

$0 up to 2M events

Plus is self-serve; Growth and Enterprise are quoted

* Free: 2M events, 10K replays, flags and web experiments
* AI agents and an MCP server on every plan, including Free
* Plus adds custom events, 20 behavioural cohorts, heatmaps, 2-year retention
* Growth and Enterprise add SSO, permissions and data access controls
* Strong warehouse-native and governance story
* CaveatPast Plus, pricing is a sales conversation, so you cannot model the bill on a napkin. The depth is real, but so is the learning curve for a team without an analyst.

Best for: Scale-ups with a dedicated analyst or data team and a warehouse already in place.

## What analytics actually costs at three sizes

Product analytics events only, calculated from published list rates in September 2026\. Replay, flags and add-ons are extra on every platform, and annual contracts lower the paid figures.

| Events per month | PostHog | Mixpanel Growth | Amplitude         |
| ---------------- | ------- | --------------- | ----------------- |
| 1M               | $0      | $0              | $0                |
| 5M               | \~$153  | \~$1,120        | Plus, usage-based |
| 10M              | \~$324  | \~$2,520        | Quote likely      |

PostHog: first 1M free, 1–2M at $0.00005, 2–15M at $0.0000343\. Mixpanel: first 1M free, then $0.28 per 1,000 at list. Amplitude: first 2M free; Plus is self-serve and usage-based, larger volumes are quoted.

**Read the gap carefully:** PostHog's event price is lower, but it meters replay, flags and errors separately, while Mixpanel's Growth plan bundles a large replay allowance. Compare on the products you will actually switch on. The cheapest way to cut any of these bills is the same everywhere: stop sending events nobody charts. Autocapture is convenient and expensive.

## When the answer is a simpler tool

A lot of teams shopping for product analytics actually want web analytics: traffic, sources, top pages, conversions on the marketing site. For that job, these two are lighter, cheaper and privacy-friendly by default — no cookie banner, a script measured in kilobytes.

![](https://www.google.com/s2/favicons?domain=plausible.io&sz=128)Plausible

Cookieless, EU-hosted web analytics on a single page of charts. Open source and self-hostable, with a paid cloud. The right choice when the question is "is the marketing working", not "which users activated".

![](https://www.google.com/s2/favicons?domain=umami.is&sz=128)Umami

Open-source, privacy-first web analytics that is easy to self-host on the same box as your app, with a hosted cloud if you would rather not. Adds basic custom events, which covers simple conversion tracking.

Many teams end up running one of each: a lightweight script on the marketing site and a product analytics tool inside the app. That is not duplication — they answer different questions for different people.

## Which one should you pick?

### You are an engineer-led team and want fewer tools

**PostHog.** One SDK gets you analytics, replay, flags, experiments and error tracking, and the free allowances cover most early products completely. Set a billing cap on each product and turn off autocapture for pages you never look at.

![](https://www.google.com/s2/favicons?domain=posthog.com&sz=128)PostHog

### Your PM should be able to answer their own questions

**Mixpanel.** It is the one a non-technical teammate is most likely to open unprompted, and self-serve adoption is the whole point of an analytics tool. Budget for the higher per-event rate once you pass 1M events, and negotiate an annual plan.

![](https://www.google.com/s2/favicons?domain=mixpanel.com&sz=128)Mixpanel

### You have analysts, a warehouse and governance requirements

**Amplitude.** Its depth, permissions and taxonomy tooling are built for exactly this, and the 2M-event free plan gives you room to prove it before the sales conversation.

![](https://www.google.com/s2/favicons?domain=amplitude.com&sz=128)Amplitude

### You cannot decide between two

Send the same events to both for two weeks — all three have free tiers large enough for a trial — and see which one your team actually opens. Usage beats any comparison table, including this one.

## Frequently Asked Questions

### Which is the best product analytics tool in 2026: PostHog, Mixpanel or Amplitude?

There is no single best one — they are built for different people. PostHog is built for engineers who want analytics, session replay, feature flags, error tracking and surveys in one product with one bill. Mixpanel is built for product managers who want fast, self-serve funnels and retention charts with the shortest learning curve. Amplitude is built for larger teams with dedicated analysts, governance needs and a data warehouse. Pick on who will open the tool every day, then check the bill at your event volume.

### Is PostHog cheaper than Mixpanel?

At the same event volume on list prices, yes, by a wide margin. Both give 1 million events a month free. After that, PostHog starts at $0.00005 per event and drops to $0.0000343 from 2 million, while Mixpanel Growth lists at $0.28 per 1,000 events ($0.00028 each). At 10 million events a month that is roughly $324 on PostHog versus roughly $2,520 on Mixpanel before any negotiated discount. Mixpanel does offer volume discounts and annual pricing, so treat its number as a ceiling, not a quote.

### Does Amplitude have a free plan in 2026?

Yes. Amplitude Free includes 2 million events a month, 10,000 monthly session replays, feature flags, web experimentation, guides and surveys, and its AI agents and MCP server. That is the largest free event allowance of the three. Above it, the Plus plan is self-serve, and Growth and Enterprise are custom-quoted, so the price at scale depends on a sales conversation.

### Do I need product analytics or just web analytics?

If your questions are "how many visitors came, from where, and which pages did they read", you need web analytics — Plausible, Umami or Google Analytics — and all three product analytics tools are overkill. If your questions are "which users activated, which feature predicts retention, where do trials drop out of onboarding", you need product analytics, because those questions are about identified users and events inside your app, not page views.

### Can I self-host PostHog?

PostHog publishes its code as open source and offers a self-hosted hobby deployment, but the company recommends its cloud for production and most teams are better served there — the free tier of 1 million events per month covers many early-stage products entirely. Mixpanel and Amplitude are cloud-only. If self-hosting is a hard requirement, Umami and Plausible are simpler self-hostable options for web analytics.

### What changed in product analytics in 2026?

The free tiers converged. Mixpanel now includes experiments and feature flags on its Free and Growth plans, Amplitude Free includes session replay, flags, web experiments and AI agents, and PostHog continues to bundle every product with a monthly free allowance. All three also ship AI assistants and MCP access so an agent can query your analytics. The result is that the feature checklist no longer separates them — the billing unit and the intended user do.

### How do I switch between PostHog, Mixpanel and Amplitude later?

Keep your event names and properties in one tracking plan, send events through a thin wrapper in your own code rather than calling the vendor SDK everywhere, and export raw events to your own warehouse if you can. Then switching is a change in one file plus a historical backfill, not a rewrite. The expensive part of changing analytics tools is almost never the tool — it is inconsistent event names nobody documented.
