Fullstory vs Heap pricing and Heap vs Fullstory cost at every session volume

Above the free tier both vendors stop publishing. Fullstory sells Business, Advanced and Enterprise behind a request pricing button. Heap sells Growth, Pro and Premier; Growth shows an estimate only after you sign up and install the tracking snippet, and Pro and Premier read custom session pricing.

The best public anchor for both is Vendr's contract data. For Fullstory, Vendr reports a median of $28,240 a year across 455 purchases, a range of $10,000 to $115,936 and an average negotiated saving of 19 percent. It also groups deals by size: Business deployments around 50,000 to 100,000 sessions a month usually land between $10,000 and $25,000 a year, Advanced deployments around 250,000 to 500,000 sessions between $30,000 and $70,000, and buyers above a million sessions with mobile capture often sign $80,000 to $200,000 or more.

For Heap, Vendr reports a median of $41,220 a year across 191 purchases, a range of $13,000 to $154,798 and an average saving of 21 percent. Vendr's written summary of Heap still talks about monthly tracked users, which is out of date; the live Heap page quotes on sessions, so ask your rep for the session count behind every number.

On the reported medians, yes. The median Heap contract is about $13,000 a year higher than the median Fullstory contract, roughly 46 percent more, and Fullstory's figure comes from more than twice as many purchases. On the free tier Fullstory is also the bigger plan by every published measure except single sign-on.

Two cautions keep that from being the whole answer. A median is a mix of company sizes, so it does not tell you what your own volume will cost. And the two medians buy different bundles: a Fullstory contract always includes replay, while a Heap contract may or may not include the replay add-on. The fair comparison is a quote from each at the same monthly session count, with replay, heatmaps and data history written into both.

Fullstory lists five add-ons on its plans page: Multi-Org Management, Mobile, Advantage Subscription, StoryAI and Guides and Surveys. Mobile analytics and Guides and Surveys are add-ons on all three paid plans, so a team that needs app capture should treat mobile as a line item, not a feature. Fullstory's Vendr data puts most large mobile deals above $80,000 a year.

Heap's add-ons cluster around the replay side of the product. Session replay, heatmaps and error analysis are add-ons on Pro and Premier and unavailable on Free and Growth. Data history beyond the first year is an add-on on Pro and Premier, up to three years. Heap also bundles the data warehouse integration into Premier rather than selling it separately, which matters if your analysts want behavioral data next to revenue data.

The practical upshot is that the base quote understates the bill on both sides, but in different places. Ask Fullstory about mobile and StoryAI. Ask Heap about replay, heatmaps and years of history.

Heap's pricing FAQ, which we read on 22 September 2026, says it will not drop or throttle data when you go over your session allowance, but that you must upgrade before you can view your data again. In other words, the data keeps arriving and the reports lock until the contract catches up. That is a reasonable policy for data integrity and an uncomfortable one at quarter end, so put the overage rate and the grace period in the order form.

Fullstory's plans page does not publish an overage policy for paid plans. Its free plan is capped at 30,000 sessions a month. Because Fullstory contracts are written around a session cap, the question to ask is the same one: what happens in the month you exceed it, and is the true-up priced at your contract rate or at list.

Heap's pricing page credits its AI assistant to Contentsquare, which owns Heap and also owns Hotjar. That matters when you are pricing replay, because Contentsquare sells its own experience analytics product with a free plan of 200,000 sessions and 10,000 replays a month, twenty times Heap Free's session allowance. If replay is your main need and Heap is on your list mainly for that, expect the conversation to move toward Contentsquare's product, and price both before you sign either. Our Hotjar vs Fullstory pricing comparison lays out Contentsquare's published ladder.

Fullstory wins when the replay is the product. Support teams that open a session from a ticket, engineers who debug from a recording with the console attached, and ecommerce teams studying checkout friction all get more from Fullstory's replay-first design, and its free plan is generous enough to prove the case before a contract.

Heap wins when the question is quantitative and retroactive. A product team that wants to define an event today and see it back to the day the snippet went in, build retention and funnel charts without engineering help, and push behavioral data into a warehouse on Premier, gets that from Heap's analytics-first model.

Neither is the cheaper choice by default. Fullstory's median contract is lower and its free plan bigger, but a Heap analytics contract without replay can come in below a Fullstory deal at the same volume. Get both quotes at the same session count.

Both tools tell you what users did. Neither tells you which complaint is costing you customers, because that answer sits in the support tickets, survey comments and app reviews that arrive alongside the behavior, and neither product reads them.

That is the gap UserInsight fills. It pulls usage, feedback, tickets and reviews into one place, groups the comments into themes, counts the customers behind each theme and ties it to churn, starting at $119.50 a month billed annually. Many teams run it next to Fullstory or Heap: the replay tool shows where users struggle, and UserInsight shows which of those struggles shows up in cancellations.
