PostHog in 2026: 5 Things After 6 Months of Use

After 6 months with PostHog: it’s a mixed bag for analytics on a budget.

In the last six months, I’ve used PostHog extensively to improve our product analytics, focusing on a mid-sized SaaS application. We’re talking thousands of active users, running experiments, tracking features, and keeping an eye on performance metrics. It’s been an adventure, to say the least.

What Works

There are a few standout features in PostHog that made me raise an eyebrow positively. Here’s a rundown:

• Event Tracking: PostHog allows you to set up event tracking without an extensive configuration process. For instance, when we launched a new feature on our app, I simply defined the events in the interface, and within minutes, I could see user interactions on our dashboard. Here’s a quick example of how it looks:

posthog.capture('feature_clicked', { propertyName: 'value' })

• Feature Flags: This feature lets you roll out changes gradually. We’ve found this especially useful. For instance, we used feature flags to test a new user interface with a select group of users before a full rollout. The toggling was smooth, and we could easily analyze the impact.
• Heatmaps: The heatmaps feature is visually appealing and pretty useful. You can see where users click, scroll, and linger. It made a significant difference when we were redesigning our landing page. We identified that a particular section was getting ignored, which prompted a redesign that led to a 15% increase in conversions.
• Self-hosting Option: The ability to self-host PostHog was a big draw for us. Given the sensitive nature of our data, keeping it in-house was a necessity. The setup was pretty straightforward, especially with their Docker support.

What Doesn’t Work

Now, let’s get real. There were some frustrations that cropped up, and honestly, they’re tough to ignore.

• Documentation: While some parts are decent, the documentation is a hit-or-miss situation. At times, I found myself banging my head against the wall trying to figure out how to implement certain features, only to find sparse examples or outdated information. A specific error I encountered was related to event properties. The docs implied a simple structure, but I ran into a constant “Invalid property structure” error until I found a forum post clearing it up.
• Performance Issues: As our user base grew, the performance took a noticeable hit. Page load times for the dashboard sometimes exceeded 5 seconds. This is unacceptable for analytics tooling. I had to scale our hosting resources significantly to cope with the demands, which added unexpected costs.
• Integration Limitations: While PostHog offers integrations with several popular tools, I found the breadth lacking. For example, integrating with our CRM was more convoluted than expected. The API documentation was vague, leading to trial and error that wasted precious development time.

The Numbers

Let’s talk data. After using PostHog for six months, here’s what I can share:

• We tracked over 100,000 events, with a peak of 10,000 events per day during our product launch.
• The self-hosted version costs us around $30/month for basic features. After scaling, we spent an additional $100/month on hosting resources.
• We experienced a 15% increase in conversion rates after redesigning our landing page, influenced by insights gathered from heatmaps.
• In terms of user engagement, we managed to retain around 80% of users post-launch, which is a win in our book.

Who Should Use This

If you’re a solo developer trying to track some basic metrics for your side project, PostHog is a good fit. The self-hosting capability means you can maintain control over your data. If your team is small and you don’t have complex needs, this could work for you.

On the flip side, if you’re a larger team or organization looking for deep analytics insights and are willing to invest in a premium tool, you might want to look at something like Amplitude or Mixpanel, which offer richer features and support.

Who Should Not

If you’re working in a large enterprise with a high volume of data and require top-tier performance, PostHog is probably not going to cut it. The performance issues I faced as our user base grew illustrated that clearly.

Also, if you need extensive integrations with third-party tools out-of-the-box, you may find PostHog lacking. If your tech stack is complex, spending time on integrations could deter your progress.
