9 Best Funnel Analysis Tools for SaaS Teams

The quick answer

Quick answer: for funnels inside a SaaS product, Mixpanel (free up to 1M events a month, funnels included on the free plan), Amplitude (free up to 2M events a month) and PostHog (1M free events a month, with sequential, strict and any-order funnels) are the strongest starting points. Google Analytics 4 is free and has funnel explorations, which is enough for marketing-site signup funnels. Heap builds funnels from autocaptured data, so you can define steps after the fact. Kissmetrics ties funnels to named people, free up to 100k events a month. If you want to see why users drop, Fullstory, Contentsquare and Mouseflow put funnels next to session replay and heatmaps. Prices are as of October 2026, checked on each vendor's own site.

What funnel analysis tools do

A funnel is an ordered list of steps, such as "visited pricing, started signup, verified email, created first project". Funnel analysis counts how many users reach each step and where the rest drop off. Good funnel tools let you change three things that decide whether the answer is useful:

• Step order: whether steps must happen in sequence, in strict order with nothing between, or in any order.
• Conversion window: how long a user has to finish the funnel before they count as dropped.
• Breakdowns: splitting the same funnel by plan, device, signup source or cohort, so you can see which group converts.

The rate at the bottom is your funnel conversion rate; our explainer on funnel conversion rate covers how to calculate and read it. For SaaS teams the most valuable funnels are usually signup to activation and trial to paid.

Product funnels vs website funnels

Website funnels track mostly anonymous visitors across pages, and tools like Google Analytics 4, Contentsquare and Mouseflow are built for them. Product funnels track logged-in users through events inside your app, and event-based tools (Mixpanel, Amplitude, PostHog, Heap, Kissmetrics) are built for them, because they tie each step to a known user and account. Many teams run one of each and join them at signup.

Funnel analysis tools compared

1. Mixpanel

Who it is for: product teams that want funnels, retention and flows in one event-based tool.

Pricing: the Free plan includes up to 1M events and 10K session replays a month, unlimited seats, and the insights, funnels, retention and flows reports. Growth starts at $0 with the first 1M events included and is priced on events after that (for example, $100 a month for 1.5M events on annual billing). Source: Mixpanel pricing.

Strengths: funnels work on autocaptured or hand-defined events, and session replay, heatmaps and rage-click detection are in the same tool. Saved behavioral cohorts, custom properties and group analytics for account-level funnels are on Growth.

Limits: on Free you can build cohorts but not save them, and account-level (B2B) funnels need the Group Analytics add-on. Compare options in our Mixpanel alternatives.

2. Amplitude

Who it is for: teams that want funnels connected to behavioral cohorts, experiments and in-app guides.

Pricing: the Free plan includes 2M events a month, 10K monthly session replays and limited experiments, guides and surveys. Plus starts at $0 with the first 2M events free, scales to 70M events, and adds custom events and formulas, 20 behavioral cohorts and heatmaps. Growth and Enterprise are quoted. Source: Amplitude pricing.

Strengths: Amplitude's Funnel Analysis chart counts a user as converted when they fire the events you chose in the order you set, and the same cohort can then be targeted with a guide or survey.

Limits: behavioral cohorts and heatmaps need Plus or above, and the event model takes time to learn.

3. PostHog

Who it is for: engineering-led SaaS teams that want analytics, replay, feature flags and surveys from one vendor.

Pricing: the first 1M events and 5K session recordings each month are free, and usage above the free allowance is billed on the pay-as-you-go plan. Free-plan event data is kept for 1 year. Source: PostHog pricing.

Strengths: PostHog's funnel docs describe sequential, strict-order and any-order step matching, breakdowns, time to convert and the paths users take inside a funnel.

Limits: the breadth of products means more settings to learn, and you pay per product once you pass each free allowance.

4. Google Analytics 4

Who it is for: marketing and growth teams measuring website and signup funnels.

Pricing: Google says Google Analytics gives you its tools "free of charge". Source: Google Analytics.

Strengths: funnel exploration supports standard or trended funnels, and an "open funnel" toggle decides whether users can enter at any step. You can save an exploration as a funnel report.

Limits: GA4 is built around sessions and marketing channels, so in-product funnels by account or plan are harder than in an event-first product tool.

5. Heap

Who it is for: teams that want to define funnels after the fact, without planning every event in advance.

Pricing: the Free plan covers up to 10k monthly sessions with 6 months of data history. Growth adds 12 months of history and is priced from an estimate after you install the snippet; Pro and Premier are sold by quote, with session replay as an add-on. Source: Heap pricing.

Strengths: Heap says its snippet captures every click, tap, pageview and form change from the moment of installation forward, so a funnel step you define today can use data back to the install date. Heap is part of the Contentsquare group and lists funnels, journeys, retention and account-based analytics.

Limits: paid prices are not published. Our Heap alternatives guide covers other options.

6. Kissmetrics

Who it is for: B2B SaaS teams that want funnels built on named people rather than anonymous sessions.

Pricing: free up to 100k events a month with 3 seats and no card. Paid plans start at $99 a month for 500k events with unlimited seats, the per-event price drops at 2M and 5M events, and annual billing is 20% off. Source: Kissmetrics pricing.

Strengths: ready-made Funnels and Activity reports, and reusable groups of people (Populations) as filters.

Limits: fewer qualitative tools (replay, heatmaps) than the all-in-one platforms.

7. Fullstory

Who it is for: teams that want to watch the sessions behind each drop-off.

Pricing: Fullstory Free includes 30,000 sessions a month and 12 months of retention; Business, Advanced and Enterprise are priced on request. Source: Fullstory plans.

Strengths: funnels, page flow analysis and conversion maps sit next to session replay, heatmaps and sentiment signals, so you can study a drop-off and its recordings in one tool.

Limits: no published prices, and mobile analytics is an add-on.

8. Contentsquare (formerly Hotjar)

Who it is for: website and marketing teams that want funnels, heatmaps and replays from one free plan.

Pricing: Free covers 200k monthly sessions with replays, heatmaps and funnels for one project; Growth starts at $39 a month. Source: Contentsquare pricing.

Strengths: see where a funnel drops, then open heatmaps and replays for that step without switching tools.

Limits: deeper product analytics is a separate Contentsquare product, and Pro and Enterprise need a demo.

9. Mouseflow

Who it is for: CRO teams that care about form abandonment and friction on key pages.

Pricing: a Free Forever plan covers 500 sessions a month; the published tiers include from 1 to 10 funnels, and paid plans are priced by sessions with up to 35% off yearly. Source: Mouseflow pricing.

Strengths: funnels with downloadable data, form analytics, automatic friction detection and journey analytics.

Limits: funnel counts are capped by plan, and tracking pauses when the monthly session allowance runs out.

How to choose a funnel analysis tool

Decide which funnel matters most. If it is visitor to signup, GA4 or Contentsquare Free will do. If it is signup to activation inside your product, use an event tool: Mixpanel or Amplitude if you want the most common setup, PostHog if you also want flags and replay from one vendor, Heap if your tracking plan is thin and you need retroactive data, Kissmetrics if you think in people and accounts.

Then make the funnel actionable. Define each step as one event with a clear meaning, set a conversion window that matches your onboarding (a day for signup, two weeks for activation), and break the funnel down by plan and signup source. When you find the step that loses most users, watch replays or heatmaps for it, and fix it with an onboarding change; our list of user onboarding tools for SaaS covers checklists and guides, and in-app components such as PLG OS (our own product) can add a step-by-step walkthrough where the funnel leaks.

FAQs

What is funnel analysis?

Funnel analysis counts how many users complete each step of an ordered sequence, such as signup, first project and invite, and shows where the rest drop off. It turns a conversion rate into a list of steps you can fix.

Can I do funnel analysis for free?

Yes. Google Analytics 4 is free, Mixpanel's free plan includes funnels on up to 1M events a month, Amplitude's free plan covers 2M events a month, and PostHog includes 1M events a month at no cost.

What is the difference between an open and a closed funnel?

In Google Analytics 4, an open funnel lets users enter at any step, while a closed funnel only counts users who start at the first step. Closed funnels are better for onboarding; open funnels help when users can join a flow in the middle.

Which funnel analysis tool is best for a SaaS product?

For in-product funnels, an event-based tool fits best: Mixpanel, Amplitude or PostHog for most teams, Heap for retroactive analysis and Kissmetrics for person-level B2B funnels. Add a replay tool such as Fullstory when you need to see why users drop.
