Open-source product analytics — events to experiments

MarketingProductivityAnalyticsDeveloperAutomation

PostHog is an open-source product analytics platform that combines event tracking, session replay, feature flags, A/B experiments, cohorts, and surveys in one self-hostable stack. Connect it to Actionist and your agents can capture events from any system, evaluate feature flags before rolling out code, read funnel and retention insights for live reporting, and react to experiment results the moment statistical significance lands — all without a single dashboard visit.

Churn signal to CSM in 60 seconds

When a support email arrives flagging drop-off from a key feature, your agent pulls the sender's PostHog person record — last active date, funnel position, cohort memberships — captures a churn-risk event, fires a Slack alert to the assigned CSM with the full context, and books a check-in call on their calendar. The CSM walks into the conversation knowing exactly where the user stalled, not guessing.

FAQs

Questions about PostHog + Actionist

How do I connect PostHog to Actionist?
Open the Apps tab, find PostHog, and click Connect. The MCP method (recommended) walks you through a one-time PostHog authorisation — select your project and confirm. If you're on a self-hosted PostHog instance, choose API key instead and paste your Personal API key from PostHog Settings → Personal API Keys along with your project's API URL.
What permissions does Actionist need on my PostHog account?
For MCP, Actionist requests project-level access scoped to the project you select during authorisation — it cannot access other projects. For API key access, your Personal API key inherits your own PostHog role; create a dedicated key with read/write scopes limited to the actions you need. PostHog does not yet support fine-grained API key scoping per resource, so treat your key like a password.
Can I combine PostHog with other apps in the same workflow?
Yes — PostHog is most powerful as part of a multi-app workflow. A common pattern: PostHog triggers an action when a cohort grows → Actionist enriches the list → HubSpot creates sequences. You can also pipe PostHog event data into Google Sheets for live reporting or feed feature-flag states into Slack alerts. Every action and trigger in PostHog works alongside any other connected app.
What are the most useful PostHog automations to start with?
Three high-impact starting points: (1) Capture Event — fire server-side events from Stripe, Zendesk, or your own backend to keep funnels complete even when client-side tracking is blocked. (2) Action Performed trigger — react in real time when users hit key milestones like 'first export' or 'pricing page viewed'. (3) Get person — enrich every sales or support touchpoint with the prospect's actual product-usage history before a human even sees the record.
How do I avoid creating duplicate events when my agent runs repeatedly?
Pass a unique event UUID in the 'uuid' property of each Capture Event or Create an event call — PostHog deduplicates on this field within a short window. For scheduled jobs that run on a cadence, include the job run ID or a datestamp in the event's distinct_id context so replays and accidental double-fires are easy to filter out in queries.
Does Actionist support self-hosted PostHog instances?
Yes. When using the API key connection method, enter your self-hosted PostHog domain as the API URL (e.g. https://posthog.your-company.com). For public POST-only endpoints like Capture Event, use the /i/v0/ path; for private read endpoints, use the root domain. MCP connection requires the PostHog cloud-hosted MCP server, so self-hosted users should use the API key method.
Which PostHog regions are supported — US Cloud, EU Cloud, or both?
Both are supported. When configuring the API key method, set the API URL to https://us.posthog.com for US Cloud or https://eu.posthog.com for EU Cloud. Use the /i/ subdomain variants (e.g. https://us.i.posthog.com) only for ingestion-only (write) endpoints that don't require authentication — private read endpoints require the main domain and your Personal API key.
How do I use PostHog feature flags in my agent workflows?
Use Get feature flag to read the current rollout state before a code deploy, or Create feature flag to scaffold new flags programmatically when a GitHub PR is merged. The Feature flag updated trigger lets your agent react the moment anyone changes a flag — useful for audit logging, QA notifications, or auto-creating rollback tasks. Pair with List experiments to track which flags are tied to active A/B tests.
