Top Heap Alternatives in 2026

PostHog is the strongest pick for teams leaving Heap over its quote-only pricing. Every product, analytics, session replay, feature flags, experiments, surveys, error tracking, has its own permanent free monthly allowance, and once you're past it you can see the exact per-unit rate, about $0.00005 per analytics event, instead of waiting on a sales call the way you do for Heap's Growth, Pro, and Premier tiers. You can also set a hard billing limit per product so a traffic spike can't blow past what you're willing to spend, something Heap's session-based pricing gives you no direct control over. Team members are unlimited on every plan. The tradeoff is that your bill still moves with traffic rather than staying flat, and support beyond community and email costs an extra $250 or $750 a month. For engineering-led teams that want analytics, replay, and flags in one contract with real visibility into cost, PostHog is the cleanest move off Heap.

Amplitude is the closest match for teams that want Heap's depth of funnels, retention, and cohort analysis without giving up features once they scale. Its Free plan covers 2M events a month forever. That's not directly comparable to Heap's 10,000-session cap since Amplitude counts events and Heap counts sessions, but for a typical app sending dozens of events per session, 2M events a month works out to well more usage than Heap's free tier allows. Every plan, including paid ones, allows unlimited seats. Plus is the only tier with a public price, $49 a month, rising automatically with event volume, so at least the entry cost is visible before you talk to anyone, unlike Heap's fully quote-only paid tiers. Session replay, feature flags, and A/B experimentation all live in the same account. The catch is that Growth and Enterprise, the tiers most teams past the startup stage actually need, are quote-only just like Heap's, and Amplitude's own CEO has publicly said pricing is the most common objection to adopting the product. Choose Amplitude when you want the most complete, proven analytics platform and can live with negotiated pricing at scale.

Mixpanel fits teams already sending clean, well-structured events who want one flat, published rate to pay past a free plan rather than the most transparent price on the market. The Growth tier charges $0.28 per 1,000 events once you clear the first 1 million free events a month, a single number you can calculate yourself rather than waiting on the sales quote every Heap paid tier requires. Worth knowing: PostHog's entry-tier rate works out to about $0.05 per 1,000 events, roughly a fifth of Mixpanel's, so Mixpanel isn't the cheapest self-serve option, just a simple one-line rate instead of PostHog's separate per-product pricing to track. Mixpanel's Growth plan also includes 20,000 free session replays a month, double PostHog's free allowance, and startups founded in the last 5 years with under $8M raised can get a free first year on Growth. Mixpanel bundles funnels, retention, cohorts, and Mixpanel Agent for AI-assisted root-cause analysis, though feature flags and experimentation cost extra as an add-on on every plan. Cost still rises directly with event volume, climbing into tens of thousands a month at high scale for some teams. This is the pick for teams that want one predictable per-event rate to forecast, not the lowest possible price.

Fullstory is the move for teams whose real complaint with Heap is that Session Replay is a paid add-on rather than a first-class feature. Its free plan already includes real session replay, 30,000 sessions a month, 12 months of retention, up to 10 users, and the paid tiers index sessions as structured, searchable data, so you can query for every session where checkout errored instead of scrubbing through recordings by hand. Rage click, dead click, and JS error detection surface friction that funnel charts alone won't catch, and coverage now spans iOS, Android, React Native, and Flutter. The downside is that Fullstory's own pricing is exactly as opaque as Heap's: Business, Advanced, and Enterprise are all quote-only, and third-party data shows SMB renewal prices climbing about 30% a year on average. Pick Fullstory when session-level debugging matters more than retroactive event analytics.

Pendo is the right swap for teams that use Heap for analytics but separately buy an in-app guide or NPS tool, since Pendo builds guides, walkthroughs, and feedback collection into the same product as its analytics. Its free plan covers up to 500 monthly active users with real analytics and in-app guides, not just a trial, and App Health rolls up visitors, retention, and NPS across every app a team owns into one dashboard. Pricing is based on monthly active users rather than sessions, so a product with heavy repeat usage from a small user base can cost less than it would under Heap's session-based model, though a MAU spike can just as easily push you into the next tier. Every paid tier, Base, Core, and Ultimate, is quote-only like Heap's, and sentiment surveys and journey orchestration stay separate add-ons until the top Ultimate tier.
