The short version

  • Each has a real cost: Heap no built-in A/B testing or feature flags; requires integration with separate tools for experimentation; Thunkable every paid tier is metered by a monthly AI token allowance, so heavy use of the AI assistant, which is the tool's main productivity feature, can be exhausted well before a billing period ends.
  • They diverge on capability: Heap covers Autocapture, Thunkable covers Block-based logic editor.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Heap

  • No built-in A/B testing or feature flags; requires integration with separate tools for experimentation
  • Group analytics and advanced features require a sales conversation, not self-serve
  • Cloud-only deployment; no self-hosted option for data security or compliance requirements
  • Session replay lacks developer debugging tools compared to PostHog
  • Pricing for Growth and Pro plans requires direct sales contact; no transparency on how pricing scales

Thunkable

  • Every paid tier is metered by a monthly AI token allowance, so heavy use of the AI assistant, which is the tool's main productivity feature, can be exhausted well before a billing period ends.
  • Only the Builder tier and above allow a live published app at all in useful numbers, so the entry-level paid plan cannot actually get an app onto the store in a meaningful way.
  • Block-based logic becomes unwieldy for apps with genuinely complex business rules, and there is no clean escape hatch to written code within the platform.
  • Native integrations and performance-sensitive features (heavy graphics, background processing) are limited compared to a coded framework, so the tool has a real complexity ceiling.
  • App ownership and export options are more restrictive than an open source framework; leaving the platform typically means rebuilding rather than exporting a portable codebase.

Answered from the vendors’ own pages

Heap: What does Heap's autocapture feature do?

Heap's autocapture is a single code snippet that automatically captures every click, swipe, tap, pageview, and form fill on your website and apps without requiring manual event setup. Once installed, Heap captures the entire digital experience of every user on every platform with no ongoing engineering maintenance needed.

Source
Thunkable: Can I publish an app on the free plan?

The free plan is aimed at building and testing; live publishing capacity in a meaningful way starts on the Builder plan.

Heap: What are Heap's pricing plans and how much do they cost?

Heap offers a Free plan for up to 10,000 monthly sessions. Growth, Pro, and Premier plans use custom session-based pricing that requires contacting sales for a quote. Free includes basic charts and 6 months data history. Growth adds the Sense AI assistant. Pro adds account analytics. Premier adds data warehouse integration and dedicated customer success management.

Source
Thunkable: What happens if I run out of AI tokens?

AI-assisted generation stops working until the next billing cycle or an upgrade; manual block-based editing still works.

Heap: Does Heap include session replay and A/B testing?

Heap includes integrated session replay showing exactly what users did on your site. However, Heap does not include built-in A/B testing or feature flags. Teams requiring these capabilities must use separate tools or integrate with third-party platforms.

Source
Thunkable: Is this suitable for a complex business app?

No. It is built for simple to moderately complex apps; heavy custom logic and native integrations are better served by a coded framework.

Heap: What integrations does Heap support?

Heap supports over 100 integrations connecting to business tools including marketing platforms, CRMs, and data warehouses. This allows insights to reach relevant teams and ensures data flows to other business systems automatically.

Source
Heap: Does Heap offer self-hosting or is it cloud-only?

Heap is cloud-only and does not offer self-hosted options. Organizations requiring on-premises deployment should consider alternatives like PostHog which supports self-hosting alongside its cloud product.

Source
Heap: What is Sense and how does it help with analytics?

Sense Chat is Heap's AI assistant that enables users to access analytics without extensive technical knowledge. It allows teams to ask questions about user behavior and get answers directly without lengthy onboarding or technical expertise, making insights more accessible to non-technical stakeholders.
