The short answer
Editorial assessmentConvert Experiences compared with PostHog
PostHog bundles experiments with product analytics, replay, and flags on one usage-based bill with a generous free tier, aimed squarely at software products. Convert is a specialist website testing tool with much stronger targeting, QA, editor, and privacy engineering, and no product analytics at all. A startup measuring its app should take PostHog; a marketing team optimising a commercial website should take Convert.
Choose Convert Experiences if
Marketing and conversion teams at small and mid-sized companies who run testing as an ongoing programme rather than an occasional experiment, especially agencies and privacy-conscious European businesses that need GDPR-safe testing with published statistics and no sales call to buy.
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.

| Setup time | A day to a first live test. Install one script, verify with the QA overlay and Live Log, build a variation in the visual editor, define a goal, launch. Full-stack and server-side testing on Pro takes longer because it involves your codebase rather than the page. | 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 visual editor is approachable and the targeting builder is drag and drop, so a marketer can be productive quickly. The statistics deserve real study: choosing between frequentist and Bayesian, understanding what sequential testing permits, and knowing when to winsorize a revenue metric are the differences between running tests and learning from them. Convert's support includes hypothesis generation help and A/A testing assistance, which suggests they know this. | Low for the web analytics dashboard; moderate for funnels, cohorts, and replay; high for SQL insights, warehouse modeling, and experimentation statistics. |

Strengths and limitations
Convert Experiences
Strengths
- The most transparent statistics of any testing tool at this price: selectable frequentist and Bayesian engines, sequential testing via asymptotic confidence sequences, automatic sample ratio mismatch detection, and named bandit algorithms.
- Genuine privacy engineering rather than a compliance page: first-party cookies only, no personal data stored by default, automatic Do Not Track support since February 2018, SOC 2 Type 2 and ISO 27001 certified.
- Published, self-serve pricing with a 15 day no-card trial in a category where almost every remaining competitor hides its numbers behind a demo request.
- Serious QA tooling, with a unified overlay, live event log, collision prevention, and version control, which is where testing programmes usually break rather than in the statistics.
Limitations
- No free tier and a $299 monthly floor billed annually, which rules it out for anyone not testing continuously.
- Multivariate testing, multipage experiments, full-stack testing, sequential testing, SSO, and raw data export all require the Pro tier, so the practical entry price for a demanding team is $420 a month billed annually.
- Both self-serve tiers carry the same 100,000 tested user allowance, so a high-traffic site cannot buy more volume without moving to a quoted Enterprise contract.
- It is a website testing tool. Product teams testing inside signed-in applications against warehouse data are better served by GrowthBook or Statsig.
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
Convert Experiences
Subscription metered on tested users per month, meaning visitors actually entered into an experiment, with tiers differing on test types, active projects, domains, and support.
- Growth$299
- Pro$420
- EnterprisePrice on request
Convert is expensive next to the testing bundled into heatmap tools and cheap next to enterprise experimentation platforms, which is exactly the gap it is built for. Working out the bill is easier than usual because the meter counts only visitors entered into an experiment. A site with 10,000 monthly users running one test at 50 percent traffic allocation consumes around 5,000 tested users a month, so it sits inside the 100,000 allowance many times over and pays $299 for capacity it will not use. A site with 100,000 monthly users running several concurrent tests across most of its traffic will approach or exceed the allowance and should price the Enterprise band. That shape means Convert is poor value for occasional testing and good value for a busy programme, and the break-even point is roughly whether you run more than one test at a time, every month, all year. What you get above cheaper alternatives is statistical machinery that holds up under scrutiny, sequential testing, sample ratio mismatch detection, named bandit algorithms, outlier handling, plus a QA layer and a privacy posture that survive a compliance review. If nobody in your organisation will ever question a test result, you do not need any of it.
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
Convert Experiences
Convert Experiences is the best remaining self-serve A/B testing platform for a marketing team that runs testing seriously. The statistics are the reason: selectable frequentist and Bayesian engines, sequential testing built on asymptotic confidence sequences, automatic sample ratio mismatch detection, outlier handling, and bandit algorithms named rather than obscured, which is more rigour than anything else you can buy with a credit card at this price. Around that sits a genuine QA layer, flicker-resistant delivery over Akamai, forty-plus targeting filters, and privacy engineering that has been ahead of regulation since 2018. Buy it if testing is a continuous programme and someone in your organisation will eventually question a result. Do not buy it for occasional experiments, because $299 a month billed annually is a lot to pay for a tool you open twice a quarter, and do not buy it as a product analytics platform or as a feature flag service, because it is neither.

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.
