| Functionality | 3 <p><span style="color: rgb(0, 0, 0);">Fathom is a lightweight web analytics tool. It covers all the essentials for this time of product including real time page view and visitor data, referral source tracking and basic traffic segmentation. However, you'll not find any powerful product analytics functionality like heatmaps or session recordings. Additionally, its self-hosted variant lacks even more features than the cloud hosted option.</span></p> | 10 <p>PostHog's functionality range is the best on the market. It excels in richness in nearly every category from automatic event capture to heatmaps to session replay recordings.</p> |
| Ease of Use | 8 <p><span style="color: rgb(0, 0, 0);">Given its limited feature set and beautiful design, Fathom is particularly easy to use. It would take an average SMB employee less than 20 minutes to master its use.</span></p> | 5 <p>PostHog’s web app can feel overwhelming due to the sheer number of controls and limited in-product guidance (e.g. tooltips or hints). Less experienced users often end up a bit lost. For example, on the Web Analytics tab, there are ~50 controls - most of which are undefined, and some (e.g. 'Paths' and 'Correlation Analysis') which even confused even fairly experienced users.</p><p>That said, inside specific areas - like session replays - controls and charts are much easier to use.</p> |

When tested, pages and charts were extremely fast to load (<1s).</p> |
| Customisability | 3 <p><span style="color: rgb(0, 0, 0);">Beyond custom events, Fathom offers limited scope for customization. We would like to have seen more options to tweak the dashboard itself and change how data is visualized.</span></p> | 8 <p>PostHog is one of the most customizable tools on the market. Everything from reports, to custom metrics to self-hosting is possible with this tool.</p> |
| Ease of Setup | 5 <p><span style="color: rgb(0, 0, 0);">Like most web analytics products, Plausible was also very simple to implement - requiring only a simple script. Additionally, it offers a self-serve free trial. However, we did find the lack of any free tier frustrating, meaning you'll need to completely delete your account if you don't want to pay.</span></p> | 7 <p>PostHog offers a self-serve product with a very generous free tier. Additionally, it was one of the first products to pioneer automatic event capture, meaning it's pretty simple to get value from the product after installing a simple script.

It also offers very strong search functionality too.</span></p> | 9 <p>As with the majority of tools in the space, the primary means for support will come from developer documentation.

| Integratability | 4 <p><span style="color: rgb(0, 0, 0);">Fathom offers a robust and well documented API through which you can interact with data programatically. However, it offers little to no integrations beyond this.</span></p> | 10 <p>PostHog offers one of the widest arrays of integrations we've tested covering everything from data warehouses, to CRMs, to CDPs and even customer support tools.
