Cutting session replay costs

We aim to be significantly cheaper than our competitors. Session replay is pay-as-you-go and you are billed for the number of session recordings at ingestion time. This means:

• The total number of sessions retained in PostHog doesn't affect your bill.
• You don't have to worry about deleting old sessions.
• You don't have to worry about the cost of storing old sessions.

Below are a few ways to reduce costs by recording fewer sessions:

1. Disable automatic recording and programmatically start and stop recordings
2. Set a feature flag with the conditions that define which users or sessions you want to record.
3. Set a minimum recording duration.
4. Set a sampling rate for recordings.
5. Make sure you capture at least one event per session to reduce the costs while maintaining all filtering options.
