The short answer
Both sides assessedJune compared with OpenPanel
OpenPanel is one of the cheaper self-serve landing spots for former June users, starting at $2.50 a month on an event meter with unlimited seats. It supports groups for company-level analysis and posts Slack alerts when an account completes a funnel, which recovers part of June's B2B model, but it does not auto-generate a starter report set or write usage back to a CRM. Expect to build the account views yourself, in exchange for a transparent price and an open source codebase.
OpenPanel compared with June
June is discontinued, having wound down into Amplitude in August 2025, so this is a question of where its former users go. OpenPanel recovers some of June's appeal for small B2B teams: group tracking for company-level analysis, Slack alerts when an account completes a funnel, and transparent pricing from $2.50 a month where June's last self-serve plan was $149. It does not auto-generate June's starter report set or sync usage to a CRM, so expect to build the account views yourself.
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.
Choose OpenPanel if
Startups, indie developers, and small SaaS or ecommerce teams who want one cookieless, EU-hosted tool covering both the marketing site and the in-product funnel, who value predictable event-based pricing with unlimited seats, and who either have enough volume that Mixpanel's paid tier would cost several times more or have the skills to self-host under the AGPL.

| Starting price | 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) | $2.50 per month billed monthly for 5,000 events, or $25 per year billed annually; self-hosting is free |
| Pricing model | 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. | One cloud plan metered only on events tracked per month, chosen from 13 published volume steps between 5,000 and 50 million events, with custom pricing above that. Every step includes the same features and unlimited websites or apps, users, dashboards, charts, and tracked profiles. Yearly billing costs ten times the monthly price. The AGPL-3.0 source can be self-hosted for free with unlimited events. |
| Free plan | No | No free cloud tier. Self-hosting is free with unlimited events, and open source projects that meet the vendor's criteria can apply for free cloud access up to 2.5 million events a month. |

| Setup time | 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. | Minutes on the cloud: create a project, paste the script tag, and the traffic overview fills immediately. Instrumenting the product events, identify calls, and group calls that make funnels and retention meaningful is a day or two of engineering. Self-hosting with the setup script is quoted by the vendor at 30 seconds to 2 minutes on a VPS once Docker and Node are present, but TLS, email, backups, and upgrade discipline are extra and ongoing. |
| Learning curve | 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. | Low for the web overview, which anyone who has used Plausible or Google Analytics will read without help. Moderate for the product side, where the skill is choosing a small set of well-named events with useful properties. The report builder is simpler than Mixpanel's, which helps non-analysts and limits power users. |

Strengths and limitations
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.
OpenPanel
Strengths
- Published, flat event pricing with no feature gates: $20 buys 100,000 events and $350 buys 10 million, with unlimited seats, projects, and profiles on every step.
- Genuinely open source under AGPL-3.0 with a documented self-hosting path and unlimited events, so the exit from the cloud is the same software rather than a migration.
- Web analytics and product analytics from one script, which removes the usual Plausible-plus-Mixpanel pairing for small teams.
- Cookieless tracking by design with a published DPA, Hetzner hosting in Germany, and a sub-processor list that keeps analytics data in the EEA in normal operation.
Limitations
- No free cloud tier, so a product that would fit inside Mixpanel's 1 million free events pays up to $90 a month here for the same volume.
- No feature flags, no experiment engine, no surveys, and no in-app guides; A/B analysis depends on assigning variants in another tool and breaking charts down by that property.
- No SOC 2 report, ISO certification, SAML SSO, or uptime SLA is published, and the company registry lists one to four employees, which will stop some procurement reviews at the first question.
- The published overage behavior is suspension rather than billing, per the terms of service, which is a harsher failure mode than an automatic step-up.
Pricing compared
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.

- CustomQuoted
OpenPanel's value depends on where your volume sits relative to Mixpanel's free tier. Under 1 million events a month, Mixpanel costs nothing and OpenPanel costs up to $90, so the argument for OpenPanel there is cookieless tracking, EU hosting, and web analytics in the same tool rather than price. Above 1 million events the arithmetic flips hard: 10 million events is $350 a month on OpenPanel, while Mixpanel's published $0.00028 per event entry rate would put the 9 million billable events above its free allowance at roughly $2,500 before volume discounts. Unlimited seats, replay included, and a flat feature set make the bill easy to forecast. What you are not paying for is maturity: no flags or experiments, no published security certifications, and a very small vendor. For a startup or indie product that is usually an acceptable trade; for a company with a procurement process it often is not.
Editorial verdict on each
June
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.
Read the full June profileOpenPanel
OpenPanel is the most interesting low-cost entrant in product analytics right now: one cookieless, EU-hosted, open source tool that covers the marketing site and the product funnel, with funnels, retention, groups, revenue events, replay, and Slack alerts included at every price and a flat event meter that starts at $2.50 a month. The math is its whole argument. Past Mixpanel's 1 million event free tier, OpenPanel is several times cheaper at the same volume, and the AGPL self-hosting route caps the downside at the cost of a server. The caveats are the ones you would expect from a three-year-old product built largely by one founder: no flags or experiments, no published security certifications or SSO, thin mobile SDK coverage on Android, suspension rather than overage billing at the limit, and a vendor small enough that its future rests on a handful of people. Buy it if you are a startup or indie team whose event bill elsewhere is the problem, or a European team that wants web and product analytics from one privacy-first tool. If you fit inside Mixpanel's free tier or your buyer needs a SOC 2 report, stay where you are.

The best in Product Analytics & Session Replay
15 trackedProduct analytics tools track what users do inside an application, funnels, retention, feature adoption, and session replay, so teams can see where activation breaks rather than guessing.
Product analytics that kept buying the rest of the stack: experiments, session replay, and a CDP under one roof, with 2 million free events a month.
A free plan covering one million events a month with unlimited seats means a 10,000 user product pays Mixpanel nothing for genuinely deep analytics.
Relaunched in 2025 around autocapture, autoconfiguration, and Ask AI, with a 2026 LLM Acquisition report, Kissmetrics is the roster's genuine comeback story.
Agent Analytics, generally available in December 2025, measures how AI agents behave inside products, a capability nothing else in this roster ships.
Autocapture records every interaction from one snippet in under an hour, so teams define events after the fact instead of instrumenting anything first.
