Mixpanel and Amplitude give the strongest free starting points, with 1 million and 2 million events per month on their free plans, so small teams can test real funnels before they spend. PostHog and LogRocket suit teams that want analytics, replay, and error data in one place, while Pendo and FullStory suit larger teams that need guides, surveys, and deeper journey work. Heap captures events automatically, which cuts setup work, but its higher tiers use custom session pricing, so ask for a written quote before you commit.

How we chose
We read the pricing page for each vendor on 2026-11-12 and took the starting price, free plan terms, and plan limits from that page. We kept only tools that track product events as a core function, with funnels, retention, cohorts, or replay as part of the product. We looked for a clear free plan or trial, a public starting price where one exists, and a real limit on the lower tiers. We did not claim hands-on testing, and we did not use third party review scores, awards, or customer counts to rank the tools.

Frequently asked questions
What is event tracking in product analytics?
Event tracking records a specific action a user takes in a product, such as a signup, a button click, a purchase, or a feature use, with the time, the user, and useful properties. Product analytics tools then group those events into funnels, retention curves, cohorts, and paths, so a team can see which steps work, where users drop off, and which features lead to repeat use.
How many events do I need to track to start?
Most teams can start with 10 to 20 core events, covering signup, activation, key feature use, upgrade, and churn signals. That list is enough to build a funnel and a retention view without drowning in noise. Review the event list each month and remove events that no one uses in a report.
Is a free plan enough for a small product?
A free plan is often enough while volume stays under the free limit, such as 1 million events per month on Mixpanel, 2 million on Amplitude, or 100,000 events on Kissmetrics. Free plans usually limit seats, retention, saved cohorts, alerts, and exports, so check those limits before you build dashboards the whole team needs. If your team needs longer history, more seats, or SSO, plan for the first step up in cost and test it during a trial.
Should I choose event based or session based pricing?
Choose event based pricing when you track many actions per user, and choose session based pricing when replay and journey views matter more than raw event counts. Event pricing can rise fast if you track every click, so use drop filters and a tight event list. Session pricing can rise fast if traffic grows, so use sampling or conditional recording where offered. Compare both models at your current volume and at twice that volume.
Do I need session replay as well as event analytics?
Session replay helps when you need to see why a funnel step failed, such as a confusing form, a broken button, or an error that only some users hit. Event analytics alone shows the drop off, while replay shows the cause. Tools such as FullStory, LogRocket, Mixpanel, Amplitude, and Pendo include replay in some plans, so check the monthly replay allowance and retention before you rely on it.
How do I keep event tracking costs under control?
Start with a written tracking plan, name events once, and avoid tracking every hover, scroll, and pageview unless a report needs it. Use drop filters, sampling, and conditional recording where offered, and set billing limits in tools such as PostHog. Review volume each month, remove unused events, and check the price at your next volume step. A monthly review of 30 minutes can prevent a surprise bill and keep reports clean.
