The platform's session recording feature captures user interactions without third-party scripts, helping teams understand exactly how users interact with their product. PostHog's generous free tier includes one million events per month, 15,000 session recordings, and unlimited feature flags, making it particularly popular with startups and product teams.

The platform uses a trigger-action model where an event in one app automatically initiates actions in other apps through Zaps, which are automated workflows. Zapier handles everything from simple two-step automations like saving email attachments to Google Drive, to complex multi-step workflows involving conditional logic, delays, formatting, and multiple app integrations. The platform's Tables feature provides a built-in database for storing and manipulating data within workflows, while Interfaces creates simple internal tools and forms. Zapier's free plan includes 100 tasks per month across five single-step Zaps.
