⚡ Reliability
Best When
Your agent needs GDPR-compliant web analytics without cookies, with a simple REST API for querying aggregate traffic metrics and custom events.
Avoid When
You need user-level tracking, session replay, or complex funnel analysis — use PostHog or Mixpanel.
Use Cases
- • Agents querying site traffic and conversion metrics to power automated marketing optimization reports
- • Content performance analysis — agents fetching top pages, referrers, and goal conversions for content strategy decisions
- • Real-time traffic monitoring — agents polling Plausible for live visitor counts and triggering alerts on traffic spikes
- • A/B testing signal collection — agents correlating Plausible event data with experiment variants for automated decisions
- • Dashboard automation — agents pulling analytics data to populate custom business dashboards without third-party cookies
Not For
- • Complex user journey tracking with session stitching — Plausible is aggregate-first, not user-level
- • E-commerce funnel analytics at depth — use PostHog or Mixpanel for detailed user behavioral analytics
- • Heatmaps or session recordings — use FullStory or Highlight for user interaction recording
Interface
Authentication
API key from Plausible account settings. Bearer token authentication. Account-wide key — all sites accessible with one key. Self-hosted instances use same auth model.
Pricing
Pageview-based pricing — predictable costs. Self-hosted version is open source and completely free. Cloud pricing is transparent and developer-friendly.
Agent Metadata
Known Gotchas
- ⚠ Stats API returns aggregate data only — no individual user/session data available (by design for privacy)
- ⚠ Date range filtering uses site's timezone — agents must account for timezone when querying same-day data
- ⚠ Custom events must be tracked via Plausible JS snippet — agents cannot ingest events via REST API
- ⚠ API rate limit (600 req/hour) is per-site — agents monitoring many sites may hit limits
- ⚠ Self-hosted Plausible uses same API but may be on older version — verify API compatibility
