Heap vs June
An independent, review-free comparison compiled by the SaaSTracker editorial team. Both products are profiled in full, and neither can pay for placement here.
The short answer
Editorial assessmentHeap compared with June
Different answers to the same complaint, that analytics tools demand too much setup. June solved it with opinionated prebuilt reports on top of a Segment stream; Heap solved it with autocapture and retroactive definition. June's product wound down into Amplitude in 2025, so it is a historical comparison rather than a live buying choice, and teams who liked June's zero-configuration promise generally find Heap's free tier the closest surviving equivalent.
Choose Heap if
Product and growth teams at small to mid-sized software companies who want analytics that answer questions retroactively without a tracking-plan project, and who value not having to negotiate engineering time for every new metric.
Choose June if
Historically: seed to Series A B2B SaaS teams that needed account-level usage analytics fast, without a data team or a tracking plan, and that already ran Segment. As of 2026 the honest answer is that it is not for anyone, because the product no longer exists; the profile is retained for teams evaluating its successors or planning a migration off it.
Side by side
13 attributes| Attribute | Heap | June |
|---|---|---|
| Category | Product Analytics | Product Analytics |
| Starting price | Free up to 10,000 monthly sessions; the Growth tier is commonly reported at around $3,600 per year (free plan available) | No longer sold (product wound down 8 August 2025); the last published self-serve price was $149 per month on the Growth plan before it was retired in October 2024 (free trial) |
| Pricing model | Session-based subscription, billed on monthly sessions rather than seats or events. Four tiers: Free, Growth, Pro, and Premier. Only the free plan has a published limit; Growth gives a self-serve estimate after you install the snippet, and Pro and Premier are quoted by sales against your session volume on an annual commitment. Session replay, additional projects, and extra years of data retention are separately priced add-ons. | Historic. June began with a freemium model (free up to roughly 1,000 active users, Growth at $149 per month, custom pricing above that). In October 2024 it removed the free plan and moved to a single all-in-one plan, quote-only, tiered by monthly active users, with every feature included at every tier and a 14-day trial. The product wound down on 8 August 2025 and is no longer sold; no current price exists. |
| Free plan | Up to 10,000 monthly sessions, 6 months of data history, core charts, unlimited enrichment sources, and SSO, with no technical support | No |
| Free trial | Free plan rather than a time-limited trial; paid-tier trials arranged through sales | Historically 14 days on the all-in-one plan; no trial is available now |

As of 2026 the honest answer is that it is not for anyone, because the product no longer exists; the profile is retained for teams evaluating its successors or planning a migration off it. |
| Setup time | Under an hour to install the snippet or mobile SDK and begin capturing. The real work starts afterwards: defining the virtual events that matter, wiring identify calls, and connecting enrichment sources typically takes a week or two of part-time effort before dashboards are trustworthy. | Historically the fastest in the category: connecting an existing Segment, RudderStack, or Freshpaint source produced auto-generated reports within minutes, and a direct SDK install was an afternoon. Getting company-level reporting right took longer, since it required engineering to send group calls with the right traits. |
| Learning curve | Low to start, moderate to do well. Building a chart is easy; writing virtual event definitions that stay correct through front-end changes is a skill, and so is resisting the urge to define an event for every interaction now that doing so is free. | Low by design. The templated reports meant most users never had to learn a query builder, and the vocabulary (active companies, power users, slipping away) mapped onto questions teams already asked. June AI's SQL editor was the only surface that assumed technical skill. |
| Platforms | Web (JavaScript snippet), iOS and Android SDKs, React Native, Google Tag Manager, Server-side libraries | Web application (SaaS), JavaScript and React SDKs, Node, Python, and Ruby server SDKs, HTTP API, Segment, RudderStack, and Freshpaint as CDP sources |

Strengths and limitations
Heap
Strengths
- Autocapture removes the single biggest failure mode in product analytics, which is discovering that the event you need was never instrumented.
- Retroactive event definition means a new metric has months of history on the day it is created, rather than starting a clock.
- Non-technical users can define events visually on the live site, so analytics work does not queue behind engineering.
- Illuminate genuinely surfaces findings nobody queried for, which is rare in a category where most tools only answer what you already thought to ask.
Limitations
- Autocapture produces a very large and noisy raw surface; without ongoing governance the event list becomes unusable and teams end up doing the taxonomy work they hoped to avoid.
- Virtual events defined against CSS selectors break silently when the front end is refactored, and a definition that is too loose quietly overcounts across all historical data at once.
- Paid pricing is opaque: Growth requires installing the snippet before you see a number, and Pro and Premier are sales-quoted with no published anchor.
- Data retention caps at twelve months on standard tiers, so year-over-year comparison requires paying for extra retention or exporting to a warehouse.
June
Strengths
- The company-level data model was genuinely differentiated: B2B retention, expansion, and churn questions answered at the account level by default rather than by workaround.
- Time to first insight was measured in minutes because reports were auto-generated from templates on connection rather than built from an empty canvas.
- It fitted the existing stack instead of replacing it, reading from Segment, RudderStack, or Freshpaint rather than demanding fresh instrumentation.
- Slack alerts and CRM write-back put usage signals in front of sales and customer success, who are the people who act on them.
Limitations
- The product no longer exists. June wound down on 8 August 2025, signups are closed, and the website now serves an acquisition notice; the YC profile lists the company as inactive.
- Data was not retained indefinitely after the wind-down: customers had a thirty-day export window, so a team that missed it has no route back to its historical event data.
- Company-level reporting depended on correctly implemented group calls. Where engineering had not sent group traits, June fell back to inferring accounts from email domain, which broke for customers using consumer email addresses or multiple domains.
- No session replay, no feature flags, no experimentation, and no in-app guides, so June was always one tool among several rather than a platform.
Pricing compared
Heap
Session-based subscription, billed on monthly sessions rather than seats or events. Four tiers: Free, Growth, Pro, and Premier. Only the free plan has a published limit; Growth gives a self-serve estimate after you install the snippet, and Pro and Premier are quoted by sales against your session volume on an annual commitment. Session replay, additional projects, and extra years of data retention are separately priced add-ons.

- ProCustom session pricing
- PremierCustom session pricing
The free plan is one of the better deals in product analytics: 10,000 monthly sessions with full autocapture, SSO, and six months of history is enough to run a real early-stage product. The step above it is where the value question gets harder. Growth at roughly $3,600 a year is competitive with Mixpanel and Amplitude for a small team, but Heap's opacity means you cannot compare on a spreadsheet without contacting sales, and the features a growing B2B team most wants (account analytics, the engagement matrix, warehouse sync) sit on quote-only tiers with add-ons stacked on top. Judged purely on capability per dollar the product is strong; judged on procurement friction for a five-person company, it is the least small-business-friendly part of an otherwise small-business-friendly tool.
June
Historic. June began with a freemium model (free up to roughly 1,000 active users, Growth at $149 per month, custom pricing above that). In October 2024 it removed the free plan and moved to a single all-in-one plan, quote-only, tiered by monthly active users, with every feature included at every tier and a 14-day trial. The product wound down on 8 August 2025 and is no longer sold; no current price exists.
- Free (retired October 2024)$0
- Growth (retired October 2024)$149
- All-in-one (October 2024 to August 2025)Quote only
For its first four years June was one of the best value purchases in product analytics for small B2B SaaS: $149 a month bought account-level retention and adoption reporting that would otherwise have meant an Amplitude or Mixpanel contract plus a data person to configure it. That value evaporated in two steps. The October 2024 move to quote-only pricing aimed at companies above $1M ARR removed the segment the tool was best for, and the August 2025 wind-down removed the product. Any team currently budgeting for June should redirect the line item; the vendor-recommended destination is Amplitude, and the closest self-serve substitutes for the company-level model are Mixpanel with group analytics enabled or PostHog with a group type configured.
Editorial verdict on each
Heap
Heap made a genuinely good bet: that the expensive part of product analytics is not the charts but the instrumentation decisions you have to make before you know what you need. Autocapture plus retroactive event definition solves that better than anything else in the category, and Illuminate turns the resulting data mass into findings rather than just storage. For a small product team without analytics engineering, the free plan at 10,000 monthly sessions is one of the strongest starting offers available. The reservations are commercial and structural. Paid pricing is quote-only above a Growth tier that will not even show you a number until the snippet is installed, session replay and retention are add-ons that inflate the real cost, and the twelve-month history ceiling undercuts the very promise of retroactive analysis. Add the Contentsquare acquisition folding Heap into a larger platform and the long-term shape of the standalone product is uncertain. Start free and stay there as long as the volume allows; before upgrading, get a written quote that includes replay and retention, and compare it honestly against PostHog and Mixpanel, both of which will tell you their price without a phone call.
Read the full Heap profileJune
June was a good product with a real idea: in B2B SaaS the account is the unit that renews, so the account should be the unit the analytics tool reasons about, and reports should exist before anyone asks for them. For four years that combination made it the most sensible product analytics purchase a small B2B software company could make, and its support and speed-to-insight earned it a review record most vendors would envy. None of that is buyable now. The company removed its free plan in October 2024 to chase customers above $1M ARR, then wound the product down entirely on 8 August 2025 when the founding team joined Amplitude, leaving customers a thirty-day export window. This profile exists as a record and a migration aid rather than a recommendation: if you are here because a spreadsheet still lists June as a vendor, the line item should be closed and the tracking code removed, and the realistic replacements are Amplitude if you want the documented path, or PostHog and Mixpanel if you want June's old price point and are willing to configure account-level analysis yourself.
