In-depth: PostHog vs Heap

Jan 10, 2024

Want to know how PostHog and Heap compare? If you remember nothing else, remember these two points:

  1. Heap is a product analytics tool designed for non-technical users.

  2. PostHog is an all-in-one platform built for engineers that replaces Heap and numerous other tools.

How is PostHog different to Heap?

1. PostHog is an all-in-one platform

Heap, like Amplitude and Mixpanel, focuses mainly on product analytics. That means you need to adopt additional tools for things like feature management, A/B testing, and surveys. PostHog combines all these features into one platform, so you can spend less time integrating different tools and more time

2. PostHog's built for engineers

We support all popular (and some unpopular) SDKs, have extensively documented APIs, and a powerful SQL query builder, so you can analyze data how you want. We make it easy to test in production, conduct phased rollouts, run beta programs, and so much more.

3. Self-serve vs talk to sales

Signing up to PostHog is as simple as creating an account and adding our JavaScript snippet to your site or app. That's it. Want more features? Just put in a card and pay for what you use. We have a generous free tier, so you may not pay anything at all. No mandatory sales calls. No boring white papers in exchange for your email.

Frequently asked questions

How long does it take to deploy PostHog?

Deploying PostHog takes mere minutes. Just include our tracking snippet in your product or website and (thanks to autocapture) you're immediately capturing events. Once up and running, you can enable session replays and other features via your project settings. See our guide to getting started on PostHog Cloud for more info.

Can PostHog also replace Google Analytics?

Yes. PostHog can replace Google Analytics for many use cases – our marketing team uses PostHog, for example. You can integrate PostHog into your website using Google Tag Manager. See our comparison of PostHog and Google Analytics 4 and an intro to PostHog for Google Analytics users for more.

How can I estimate my usage?

The easiest way is to sign up to PostHog, integrate our snippet, then check the projection on your billing page after a few days. Alternatively, you can guesstimate by multiplying your current monthly active users by an estimate of events generated per user – 50 to 100 per user is a good starting point. See Estimating usage & costs in our docs for more.

Does PostHog block bots by default?

Yes. See the full blocklist in our docs.

What about ad blockers?

We recommend all users deploy a reverse proxy, which enables you send events to PostHog Cloud using your own domain. Events sent from your own domain and are less likely to be intercepted by tracking blockers, ensuring you capture the best data possible. We have reverse proxy setup guides for AWS Cloudfront, Caddy, Cloudflare, Netlify, Vercel, and more, in our docs.

Can I use PostHog with a CDP? (Segment, Rudderstack, etc.)

Yes. See Using PostHog with a CDP in our docs.

Can you use PostHog on e-commerce websites?

Absolutely. PostHog is easy to integrate with Shopify. You can easily install PostHog on other e-commerce platforms using our Javascript snippet – see our guides to setting up Webflow analytics and Wordpress.
