8 Amplitude Alternatives Compared for 2026

Amplitude moved from tracked users to event-based pricing during 2026 and still does not publish a rate above the free tier. That is the reason most teams start looking for an alternative: not because the product disappointed them, but because nobody in the room can say what it will cost next quarter. This guide compares eight alternatives on prices read from each vendor's own page in September 2026, on what each one meters, and on who it actually fits. One of them, Arktis, is ours, and the section says so.

The short answer: Arktis for stores, Mixpanel or PostHog for product teams

If you run an online store, Arktis is the clear winner here, and it is not close. Every other tool on this list measures behaviour; only Arktis connects the order back to the ad that produced it, reports customer acquisition cost and return on ad spend per campaign, and plays the buyer's session recording next to that number. It is priced on monthly tracked visitors at $49, $149 and $349 a month, published, with a 7-day free trial on Growth, so the bill does not move when a campaign triples your traffic for a week.

If you are a software product team, the honest answer is different. Mixpanel is the closest like-for-like swap with a published rate, PostHog is the choice if your engineers want analytics, replay and feature flags in one place, and Google Analytics 4 is the free baseline if your questions are about traffic rather than product behaviour.

Key takeaways

Amplitude publishes a free tier of 2 million events a month with 10,000 session replays and says nothing about the price above it, so the only public evidence of what a paid plan costs is contract data: Vendr's marketplace, updated February 2026, reports a median of $64,724 a year across 416 purchases. Three of the eight alternatives here publish a rate you can multiply out before you talk to anyone, three quote only, and two are free. For an online store the deciding factor is not the rate at all, it is that none of these tools except Arktis can tell you which campaign produced an order.

The 8 best Amplitude alternatives

1. Arktis, the winner for online stores

Arktis is an attribution and user journey platform built for e-commerce rather than for software products. It captures the fbclid and gclid identifiers when a visitor lands, imports Shopify orders, matches Stripe customers to anonymous visitors through a four-pass waterfall, then reports customer acquisition cost and return on ad spend per campaign with switchable first-touch, last-touch, linear, time-decay and position-based models. The session recording of each attributed buyer sits next to the number, gated behind explicit consent, with capture buffered in the browser and discarded unless consent is given, and data hosted in the EU by default.

Pricing is on monthly tracked visitors and every tier is published: Starter at $49 a month for 50,000 visitors, Growth at $149 for 250,000 with session recordings and custom attribution models, Scale at $349 for unlimited visitors with API access and raw export. Growth carries a 7-day free trial. Because the meter is visitors and not events, an autocapture change or a viral week does not produce an invoice surprise, which is the specific failure mode people leave Amplitude over.

Where it does not fit: Arktis has no feature flags and no experimentation platform. If you are running a product-led software business that needs A/B tests wired into the same tool as the analytics, Amplitude and PostHog both do that and Arktis does not.

2. Mixpanel, the closest swap with a published rate

Mixpanel is the like-for-like replacement most Amplitude teams land on. The first million events a month are free, above that the rate is $0.00028 per event, and Growth includes 20,000 session replays. Enterprise is quoted, and Mixpanel's own documentation states that its tracked-user Enterprise plan starts at $20,000 a year. The published rate is the point: five million events a month is $1,120, four million billable events at $0.00028, and you can check that arithmetic yourself before a sales call.

The trade is depth. Mixpanel's behavioural analysis is good but not Amplitude's equal at the top end. It added feature flags and experiments to its Free and Growth plans in September 2026, but caps them at 10 and 50 active flags, where Amplitude's are unlimited. It also charges the same for an anonymous event as an identified one, which cuts both ways depending on your traffic mix.

3. PostHog, if your engineers own analytics

PostHog bundles product analytics, session replay, feature flags and experiments, meters each separately, and gives away one million events and 5,000 recordings a month before charging. Above that it charges $0.000198 per identified event and $0.00005 per anonymous one, so the bill depends heavily on how much of your traffic signs in. It is open source, self-hostable, and clearly designed for teams who are comfortable in a query editor.

The cost of that flexibility is that four separate meters are four separate ways to be surprised, and the interface assumes technical fluency. Non-technical stakeholders tend not to self-serve in PostHog.

4. Heap, for autocapture without instrumentation

Heap captures everything on the page retroactively, so you can define an event after the fact and still have the history. That removes the event-taxonomy problem that reviewers complain about most on Amplitude. The free tier is 10,000 sessions a month. Every paid tier is quote only, which means you are swapping one opaque pricing model for another, and Heap is now part of Contentsquare.

5. Google Analytics 4, the free baseline

GA4 is free and it is what most stores already have. Its limits are documented rather than hidden, and they are real: event-level data retention on the free tier caps at 14 months, with 26, 38 and 50 months reserved for Analytics 360; ad-hoc queries sample above 10 million events; and the free daily BigQuery export is capped at one million events a day, with Google's own documentation warning that a property which consistently exceeds it will have the export paused. Analytics 360 lifts all of that, and Google has never published its price. Partner sources put the GA4 360 entry point at about $50,000 a year including 25 million events a month.

For a store, the deeper issue is attribution. GA4 removed first click, linear, time decay and position-based attribution models in November 2023, leaving data-driven and two last-click models, so the model comparison a merchant wants is no longer available in the free product at all.

6. FullStory, for deep session replay

FullStory is the strongest pure replay product in this list, with autocapture, a generous free tier of 30,000 sessions, and a data layer that UX researchers genuinely like. It is quote only on every paid tier; Vendr puts the median contract at $28,240 a year. It answers what a visitor did, never what the click cost.

7. Contentsquare, the tool that used to be Hotjar

Hotjar is now part of Contentsquare, and hotjar.com/pricing redirects to the Contentsquare pricing page. The free tier is unusually generous at 200,000 sessions a month, with replays capped at 5 percent of sessions up to 10,000, paid starts at $49, and you get heatmaps, replay and on-site surveys. It is a page-experience tool, not a product analytics one, so it replaces a slice of what Amplitude does rather than the whole thing.

8. Microsoft Clarity, free heatmaps and replay

Clarity is free with no paid tier and no session cap, which makes it the cheapest way to add heatmaps and replay next to whatever else you run. It is not a product analytics replacement, it does not do funnels the way Amplitude does, and Microsoft's terms are the price of admission. As a second tool alongside a primary one it is hard to argue with.

Where Amplitude is still the right answer

Three situations genuinely favour staying. If you need behavioural analysis, experimentation and feature flags governed in one platform with enterprise controls, Amplitude does that better than anything else here and the alternatives each cover only part of it. If you are a small company that qualifies for the startup scholarship, one year of Growth free with 200,000 monthly tracked users for companies under $10 million raised and fewer than 20 employees is a better deal than any paid tier on this page. And if your data lives in Snowflake, warehouse-native Amplitude runs against your own tables with the first five seats included, which no tool on this list matches.

Amplitude also holds 4.5 out of 5 on G2 from more than 2,700 reviews, so this is a question of fit and predictability, not quality.

How to choose

Start with the question you are actually paying to answer. If it is which ad produced the order, you need attribution, and that rules out every tool here except Arktis. If it is why users drop out of a flow, you need event analytics, and Mixpanel or PostHog will do it for a rate you can calculate. If it is where visitors hesitate on a page, you need heatmaps and replay, and Clarity does it for nothing.

Then check the meter against your own traffic shape. Event-metered tools punish autocapture and traffic spikes; session-metered tools punish long visits; visitor-metered tools punish nothing you cannot forecast a month ahead. A store with seasonal peaks should weight that heavily.

To see attribution and recordings on your own traffic, start the 7-day Growth trial. The tiers are on the pricing page, the feature-by-feature comparison is on Arktis vs Amplitude, and Amplitude pricing covers what the company does and does not publish.
