Overview

How each tool is described

Heap

What is Heap?


Heap is a product analytics platform that automatically captures interactions across websites and mobile apps, giving teams retroactive behavioral data for funnels, journeys, retention, and experience analysis without requiring every event to be defined in advance.


  1. Data capture: Autocapture records interactions such as clicks, taps, pageviews, swipes, screen views, and form activity. Teams can supplement this data with manually tracked, API-based, and server-side events when additional business context is needed.
  2. Analysis role: Journeys visualizes the paths users take before and after key actions, including alternate routes and conversion rates. Integrated Session Replay adds visual context so teams can move from an analytics finding to the sessions behind drop-offs, friction, or unexpected behavior.
  3. AI assistance: Sense Chat lets users ask behavioral questions in natural language, generate charts, review AI-written data summaries, ask follow-up questions, and inspect how the analysis was produced without manually configuring each report.
  4. Commercial considerations: Heap offers Free, Growth, Pro, and Premier plans. Session allowances, data history, account analytics, warehouse connectivity, regional storage, and other capabilities vary by tier, while Experience Analytics and Heap Connect are add-ons on some plans.


Heap is particularly relevant to teams that want to investigate product behavior retrospectively and answer questions using already captured interaction data instead of depending entirely on an event-tracking plan established in advance.

PostHog

What is PostHog?


PostHog is a product engineering platform that brings product and web analytics, Session Replay, heatmaps, feature flags, experiments, surveys, error tracking, data warehousing, CDP capabilities, and AI tools into one system for building and improving digital products.


  1. Product insight: teams can analyze funnels, retention, paths, user behavior, and website traffic, then move into session recordings and heatmaps to investigate the individual experiences behind quantitative trends.
  2. Release workflow: feature flags and experiments connect behavioral measurement with controlled rollouts and A/B tests. PostHog also offers no-code A/B testing, allowing teams to test some changes without implementing every variant directly in application code.
  3. AI and data: PostHog AI can work across product analytics and broader platform context to answer questions, create analyses, find relevant replays, and work with SQL. Its context warehouse can combine PostHog product signals with data from more than 120 external sources and destinations, including Stripe, Postgres, and HubSpot.
  4. Commercial considerations: PostHog uses usage-based pricing with separate monthly free allowances for its products. Current free tiers include 1 million Product Analytics events and 5,000 Session Replay recordings, alongside separate allowances for feature flags, surveys, warehouse rows, error tracking, AI, and other products.


PostHog is particularly relevant to product engineering teams that want analytics, experimentation, debugging, customer data, and AI context available within the same platform instead of assembling and synchronizing several independent developer tools.
