August 2024 Summaries

PostHog's marketing team developed a strategy to enhance their social media presence by sharing changelog updates in a more visual format, recognizing that image-based posts perform better on platforms like X compared to text-based links. To overcome the challenge of creating images for each update without overburdening the design team, they explored automating the image generation process. Drawing inspiration from a previous project that auto-generated custom open graph images, they designed a template pulling data from their CMS, incorporating elements such as product branding and hedgehog graphics, which are central to PostHog's identity. This process involved using html-to-image technology to render and download images efficiently, allowing team members to easily generate high-quality visuals for social media.

PostHog has significantly reduced the cost of session replay and is now introducing a new pricing model for its event tracking, making it up to 80% cheaper for tracking anonymous users. This change is expected to decrease product analytics revenue by about 30% but opens up possibilities for web analytics at scale and tracking high-volume backend events. Previously, all events were charged at the same rate, but the new model differentiates between identified events, related to logged-in users and associated with personal profiles, and anonymous events, which involve non-identifying data. Anonymous events are now cheaper to process because they rely on more efficient ClickHouse tables rather than the more complex Postgres processing required for identified events. This shift allows businesses to save significantly while maintaining flexibility in tracking both anonymous and identified users, encouraging growth through enhanced customer retention and word-of-mouth promotion.
