Countly vs PostHog
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 assessmentCountly compared with PostHog
The closest philosophical rival, and the harder comparison for Countly. PostHog is also open source and self-hostable, with a generous free cloud tier, plus session replay, feature flags, and experiments in one product. PostHog's centre of gravity is web and product-led SaaS; Countly's is mobile and regulated deployment, with better native mobile SDKs, push notifications, and crash reporting with symbolication. If you are a web SaaS team, PostHog is usually the better and cheaper answer. If you ship native mobile apps into a regulated market, Countly fits better.
Choose Countly if
Mobile and multi-platform product teams with a data residency, regulatory, or sovereignty constraint that rules out sending raw events to a US cloud, and teams that want analytics, push, surveys, and A/B testing from one server instead of four vendors.
Choose PostHog if
Engineering-led SaaS and product teams that want web analytics, product analytics, replay, flags, and experimentation consolidated in one usage-priced platform, and that are comfortable doing their own revenue-attribution modeling if they need it.
Side by side
13 attributes| Attribute | Countly | PostHog |
|---|---|---|
| Category | Product Analytics | Analytics |
| Starting price | Free if self-hosted (Lite); managed Flex starts at $175 per month (free plan available) | $0 (generous monthly free tiers; pay only past the allowance) (free plan available) |
| Pricing model | Three editions. Countly Lite is free and open source under AGPLv3, self-hosted, and limited to the aggregate analytics layer. Countly Flex is a managed private cloud priced by monthly active users and data points, with a base Advanced Analytics plan and two paid capability bundles (Adaptivity and Intelligence) added on top. Countly Enterprise is a self-hosted commercial license with all capabilities included, priced by quote and billed annually. | Usage-based pricing per product: every product has a monthly free allowance, then per-unit billing (per event, recording, flag request, survey response, or row) with steep volume discounts; optional platform packages add support and compliance features. |
| Free plan | Countly Lite is free forever but self-hosted, and excludes drill, funnels, cohorts, and user profiles. The free tier that previously existed on the hosted Flex plan was removed in 2026. | 1M analytics events, 5K session recordings, 1M feature-flag requests, 100K exceptions, 1,500 survey responses, and 1M data warehouse rows per month, on 1 project with 1-year retention. |
| Free trial | 14 days on Flex (credit card required); demo environment for Enterprise | Not applicable; the free tier is permanent, not a trial |
| Best for | Mobile and multi-platform product teams with a data residency, regulatory, or sovereignty constraint that rules out sending raw events to a US cloud, and teams that want analytics, push, surveys, and A/B testing from one server instead of four vendors. | Engineering-led SaaS and product teams that want web analytics, product analytics, replay, flags, and experimentation consolidated in one usage-priced platform, and that are comfortable doing their own revenue-attribution modeling if they need it. |
| Setup time | A Flex instance and a first SDK integration can be live in a day. Self-hosting Lite or Enterprise is a genuine infrastructure project: provisioning, MongoDB, TLS, backups, and upgrade planning, typically a few days for someone who has done it before and longer for someone who has not. The instrumentation work, deciding which events to fire and what properties to attach, is the part that takes weeks regardless of edition. | Minutes to first data with the JS snippet and autocapture; days to weeks to define clean custom events, dashboards, and cohorts; warehouse sources and pipelines are a separate project. |
| Learning curve | Moderate. The aggregate dashboards are readable immediately. The harder skill is event design, because Countly rewards a small number of well-segmented events and punishes a sprawl of one-off event names; Data Manager exists precisely because most teams get this wrong first. Operators of self-hosted deployments need MongoDB familiarity as an ongoing requirement, not a one-time one. | Low for the web analytics dashboard; moderate for funnels, cohorts, and replay; high for SQL insights, warehouse modeling, and experimentation statistics. |
| Platforms | iOS, macOS, watchOS, tvOS, Android, Web (JavaScript SDK), React Native, Flutter, Cordova, Ionic, Unity and Unreal, Desktop (Windows, macOS, Linux), Node.js, Java, .NET, Python, PHP, IoT and connected devices | Web app, JavaScript snippet and web SDK, Server SDKs (Python, Node, Go, PHP, Ruby, and others), Mobile SDKs (iOS, Android, React Native, Flutter), Self-hosted Hobby build (Docker, open source) |

Strengths and limitations
Countly
Strengths
- Genuine self-hosting, including a free open source edition, which very few product analytics tools still offer credibly.
- Analytics and engagement in one system: a cohort defined from behavior is immediately addressable by push, in-app message, survey, or journey.
- Breadth across mobile, web, desktop, and IoT from one server, with mature first-party SDKs on all of them.
- Crash reporting with symbolication built in, so app stability and product behavior share a single app version and device breakdown.
Limitations
- The hosted free tier was removed in 2026, so the cheapest managed entry point is now $175 per month, which puts Countly out of reach for many small teams that would have trialled it.
- Lite lacks the granular data store, so funnels, cohorts, drill, flows, and user profiles are simply absent from the free edition. This is the single most misunderstood thing about Countly.
- On Flex, funnels and cohorts sit in the paid Intelligence bundle rather than the base plan, so the real cost of a comparable analytics setup is above the advertised entry price.
- Self-hosting means operating MongoDB. Reviewers repeatedly report friction with the Docker image, memory pressure, and incompatibility with some managed MongoDB providers, and the minimum viable server is larger than teams expect once push notifications are enabled.
PostHog
Strengths
- Breadth with real integration: analytics, replay, flags, experiments, surveys, error tracking, and a warehouse genuinely share one event stream and identity graph rather than being bolted-on acquisitions.
- The most generous free tier in the category, 1M events and 5K recordings monthly, permanently, which makes evaluation and early-stage use genuinely free.
- Open-source codebase plus a choice of US or EU (Frankfurt) cloud gives privacy and procurement teams inspectability and residency options most rivals lack.
- Usage pricing with automatic volume discounts and per-product spending caps scales from hobby project to hundreds of millions of events without a sales call.
Limitations
- No packaged B2B revenue attribution: connecting spend and touchpoints to CRM pipeline and closed-won revenue is a data-warehouse project in PostHog, not a built-in report as in Dreamdata or HockeyStack.
- Depth demands technical investment; non-technical marketers can read the web dashboard but will struggle to self-serve funnels, SQL insights, or warehouse joins.
- Usage-based billing is unpredictable without configured limits, and replay-heavy or autocapture-noisy sites can generate surprising invoices.
- The full event platform carries more GDPR surface than minimalist tools: consent, masking, and retention need deliberate configuration, where Plausible or Fathom are compliant nearly by default.
Pricing compared
Countly
Three editions. Countly Lite is free and open source under AGPLv3, self-hosted, and limited to the aggregate analytics layer. Countly Flex is a managed private cloud priced by monthly active users and data points, with a base Advanced Analytics plan and two paid capability bundles (Adaptivity and Intelligence) added on top. Countly Enterprise is a self-hosted commercial license with all capabilities included, priced by quote and billed annually.
- Lite$0
- FlexFrom $175
- EnterpriseCustom quote
Countly's value depends almost entirely on which edition you are talking about. Self-hosted Lite is one of the few genuinely capable free analytics servers, and for a team with infrastructure skills it delivers sessions, events, crashes, and push for the price of a VM. Managed Flex is not cheap at $175 per month for a base plan that excludes funnels and cohorts, and against Mixpanel's or PostHog's free and low tiers it loses on price outright. What you are actually buying at that price is isolation: your own instance, your choice of region, and no shared multi-tenant store. If data residency is a requirement rather than a preference, that premium is the whole point and it is reasonable. If it is not, the hosted incumbents give more analytics per dollar.
PostHog
Usage-based pricing per product: every product has a monthly free allowance, then per-unit billing (per event, recording, flag request, survey response, or row) with steep volume discounts; optional platform packages add support and compliance features.
- Free (no card)$0
- Pay-as-you-goUsage-based
- Platform packages (Boost, Scale, Enterprise)Quoted / package pricing
At small and mid scale PostHog is close to unbeatable on price: the permanent free tiers cover a real startup's entire measurement stack, and the per-unit rates undercut buying analytics, replay, flags, and experimentation separately. The honest caveat is that usage pricing shifts the budgeting burden onto you: a replay-heavy or event-noisy implementation can quietly cost more than a flat-rate point tool, and the platform packages needed for enterprise compliance are quoted, not listed. Treat it as extremely cheap by default and only as cheap as your instrumentation discipline at scale.
Editorial verdict on each
Countly
Countly is the answer to a specific question: what do you use when the behavioral data cannot leave your control? On that question it is one of a very small number of credible options, and it goes further than its self-hosted peers by putting push notifications, in-app content, surveys, A/B testing, and crash reporting on the same server as the analytics, so a cohort you define is a cohort you can message. Thirteen years of independent, bootstrapped development shows in the breadth of the SDKs and the seriousness of the governance tooling. The problem is the middle of the market. The 2026 removal of the Flex free tier and a $175 per month entry price that still excludes funnels and cohorts means a small business without a data residency requirement will get more analytics for less money from Mixpanel, PostHog, or Amplitude, and a small business with no operations capability should not casually take on self-hosted MongoDB. Buy Countly when regulation, sovereignty, or vendor consolidation on mobile is the actual constraint. If it is not, buy something cheaper.

Category LeaderPostHog is the default recommendation in this category for any team with an engineer on it: no rival matches the combination of a free-forever tier that covers real workloads, usage pricing that scales without a sales call, and genuinely integrated replay, flags, and experimentation on top of web and product analytics. The two honest reservations are that marketing teams without technical support will use a fraction of it, and that B2B pipeline attribution, the question GTM leaders most want answered, remains a do-it-yourself exercise on PostHog's warehouse rather than a shipped feature. Buy it as the behavioral system of record; budget separately if you need turnkey revenue attribution.
