PostHog Alternatives: Best PostHog Competitors, PostHog Pricing and Alternatives to PostHog Compared

PostHog alternatives at a glance

Short answer: most people shopping for a PostHog alternative are not trying to escape the price. PostHog has no subscription fee, publishes a per-unit rate for every product, and says 97% of its companies use it for free. The three real reasons to leave are that it assumes an engineer, that single sign-on costs $250 a month even when your usage costs nothing, and that it is a product-analytics platform rather than a tool that tells you what to change on a page. Amplitude and Mixpanel are the closest analytics swaps, Statsig and GrowthBook the closest experimentation swaps, Microsoft Clarity the free replay swap, and Converto the pick if you want the page fixed rather than measured. Every figure below was read at PostHog's own pricing page and public handbook on 1 September 2026.

What PostHog costs in 2026

PostHog has exactly two plans, and neither carries a subscription fee.

Two things in that table are unusual enough to call out. There are no per-seat charges at all, which makes PostHog structurally cheaper than seat-priced analytics for a big team. And on the free plan, usage simply stops at the limits, so you cannot be billed by surprise. On paid, you set your own billing limit for each product separately.

The per-unit rate card

Each product has its own meter and its own monthly free allowance, and the allowance resets every month whether or not you have a card on file.

Web analytics is bundled into product analytics at no extra cost, and experiments are bundled into feature flags on the same meter and the same free tier, so A/B testing on PostHog is genuinely free up to a million flag requests a month. That single fact undercuts most of the experimentation market, where the entry price for split testing runs from $99 a month at Crazy Egg to a sales call at Optimizely, AB Tasty and Adobe Target.

What a real bill looks like

Rate cards are hard to translate into a number, so here is the arithmetic worked through at three sizes, using the published tiers.

The third row is not a joke. It is PostHog's own published claim about 97% of its customer base, and it is the single most useful thing to know before you spend a week evaluating alternatives on cost.

The three real reasons to look for a PostHog alternative

1. It assumes you have an engineer

This is the big one and it is a design decision, not a flaw. You install an SDK, decide which events matter, and ship experiment variations in code. Autocapture reduces the instrumentation work by recording clicks and pageviews automatically, but it does not remove the install, and nothing in PostHog will write a better headline for you. A marketing team with no developer time will stall at step one.

2. Single sign-on costs $250 a month

Usage is not where a PostHog bill goes wrong. Platform packages are, and they are flat fees stacked on top of usage.

Follow that through for a normal company. If your usage sits inside the free tier and your IT team requires single sign-on, your analytics cost $0 and your SSO costs $3,000 a year, so the platform package is 100% of your PostHog invoice. Role-based access control, which plenty of mid-size companies treat as basic hygiene, sits at $24,000 a year.

Here PostHog genuinely loses, and to a tool we have criticized elsewhere: Heap puts SSO on its free plan. Amplitude gates SSO to a sales-quoted tier and Mixpanel to Enterprise, so PostHog is not an outlier, but Heap beats all three on this one column and we would rather say so than pretend the transparency argument wins every category.

3. It measures, it does not prescribe

PostHog will tell you, accurately and cheaply, that 41% of visitors abandon on step two of your signup. It will not write the better step two. That gap is the reason a large share of the people searching for PostHog alternatives are not really looking for another analytics tool at all. They already know where the leak is. They want the fix.

PostHog alternatives compared on published pricing

The column that matters most in this table is the last one, because it is the one every vendor comparison quietly skips.

Read that column and PostHog wins it outright. Optimizely, Adobe Target, AB Tasty, FullStory and Heap publish no price at any tier. Heap goes furthest in the other direction: its Growth card asks you to sign up and install its JavaScript to get an estimate, so costing the tool requires a production release. PostHog puts the entire rate card in a plain text file addressed to AI agents.

The discount ladder PostHog publishes and nobody else does

This is the finding that makes PostHog genuinely unusual rather than merely cheap. Discount schedules are normally the most closely guarded document in enterprise software, because they are the sales rep's leverage. PostHog publishes its own in a public handbook, along with the instruction that reps should not exceed it.

Two additional levers stack on top. Paying additional contract years upfront adds up to 5%, and committing in writing to a signature date adds 5%. Asking for payment terms past Net 30 subtracts 2.5% for every 15 days, so Net 60 costs you 5%. Stacked at the published ceiling that is a 50% discount, and the handbook is explicit that the volume tier is a prerequisite: you cannot claim the timing discounts without first buying $25,000 of credit.

Read the fine print carefully, because two details in it are easy to get backwards. The tier is set by credit value, not cash paid, meaning the list-price value of the credits before the discount is applied. And it is measured per contract year, not per term: a two-year deal with $250,000 of credit each year sits in the 35% tier, not the 40% one.

There is also a small contradiction worth knowing about, because it will cost you money if you assume the simpler version. PostHog's pricing page summarizes the second lever as a 2-year commitment earning 3% and a 3-year commitment earning 5%. The handbook is more precise and less generous: the discount is 2.5% per additional year paid upfront, and the handbook states plainly that length of commitment is not a lever it uses. A three-year contract invoiced annually earns nothing extra. The prepayment is what earns the discount, not the signature.

None of this applies to most readers, and we would rather point that out than oversell it. The ladder starts at $25,000 of credit and PostHog says 97% of its companies pay nothing at all. There is a self-serve route for smaller accounts, though: 10% off credit purchases below $25,000, available in-app to customers with at least three paid invoices averaging $280 or more.

Startup, YC and nonprofit credits

If you qualify for one of these, PostHog stops being a pricing question entirely.

For context, the mid-size SaaS in our worked example above pays roughly $4,385 a year. A qualifying startup receiving $50,000 in credits would need to be an order of magnitude larger than that before paying anything.

Is the open-source version a real alternative?

Partly, and the fine print matters. PostHog is MIT licensed and offers a free Docker Compose deployment, so you can run the same product on your own infrastructure at no license cost. What you take on is more than server bills. PostHog states that self-hosted deployments are officially unsupported, that it does not do tagged releases, and that it does not publish CVEs because self-hosted instances have no versions, with every change shipping continuously from master. It offers no guarantees and no paid support plans for self-hosted instances.

So "free and open source" is accurate and "supported" is not. For a team with genuine data-residency or compliance requirements and the platform engineering to back it, that trade is often worth making. For a team self-hosting purely to avoid a bill, the arithmetic rarely works: the cloud free tier is generous enough that most of them would pay $0 anyway, and they would be paying an engineer to maintain what PostHog runs for nothing. If open source is the actual requirement rather than the price, GrowthBook is worth a look for the experimentation half specifically, since it is warehouse-native and designed to be self-hosted.

Best PostHog alternatives by job

If you want product analytics: Amplitude or Mixpanel

Amplitude owns funnels, retention and behavioral cohorts, and its free tier now includes 10,000 sessions of replay a month. Mixpanel is the more self-serve of the two, with a public pricing slider and a buy-online path that does not route you through a sales team. Both publish more than Heap does, which publishes nothing. If autocapture is the specific thing you like about PostHog, Heap is the closest match on that mechanic, and our roundup of the best Heap alternatives works through why its pricing is the hardest to evaluate in the category.

If you want session replay only: Microsoft Clarity

Clarity is free, unmetered and unsampled, which no paid tool in this set can match on price. Its limit is retention rather than volume, and it is not a product-analytics platform. If replay is genuinely all you need, paying anything is hard to justify. Our comparison of the best session replay tools covers the full field including FullStory, Hotjar, Lucky Orange and Mouseflow.

If you want experimentation: Statsig or GrowthBook

Statsig is the closest thing to a specialist upgrade from PostHog experiments, with a strong free tier and published rates. GrowthBook is free, open source and warehouse-native, which suits teams that already have the data in Snowflake or BigQuery and do not want a second copy of it. Both avoid the enterprise sales process that Optimizely, AB Tasty and Adobe Target require. The full field is in our guide to A/B testing tools.

If you want the page fixed rather than measured: Converto

This is the one PostHog does not compete on, because it was never trying to. Converto has no SDK, no event pipeline and no session replay, and it does not track your visitors at all. Paste a live URL and it audits the copy, layout, CTAs, page speed and AI-readability, names what is costing you conversions, and generates the rewritten variants ready to ship. It works with zero traffic, because it reads the page rather than waiting for a sample to accumulate.

For most readers the sensible answer is both, not either. Keep PostHog on the free tier to measure what happens, and use Converto to decide what to change. If you want the wider category rather than a like-for-like swap, our roundup of the best CRO tools covers the whole field, and the PostHog alternative comparison goes deeper on the head-to-head.

Who should stay on PostHog

Most people reading this page. Specifically: if you have an engineer, if you want analytics, replay, flags and experiments on one bill rather than four contracts, and if your usage sits anywhere near the free tier, there is no cheaper or more transparent option in this category and switching is a waste of a quarter. The vendor publishes its rates, its packages, its discount schedule and its contract rules, and it commits in writing to match the cheapest competitor at every scale.

Leave if one of three things is true: you have no developer time and need a marketer-operated tool, you need SSO or RBAC and cannot justify $250 to $2,000 a month for it, or what you actually wanted was something that writes the fix instead of measuring the problem. Those are real reasons. "It got expensive" usually is not, and it is worth checking your actual invoice before you believe it.
