PostHog vs Swetrix (2026): which should you pick?

Pick PostHog if

• Fits if you're a startup that wants analytics, replays and flags within the free allowance
• Works for developers who want to go from a broken session to the error behind it

Look elsewhere if

• Skip it if you just want simple visitor counts without learning a whole toolkit
• Pricey if you need SSO or a HIPAA BAA, which take Boost at $250 a month on top of usage; SAML takes Scale at $750
• Not for you if you want a fixed monthly bill, as everything past the free allowance is metered
• Tight if you stay free, with 1 project, recordings kept a month and events dropped past the limits
• Watch out: self-hosted PostHog is officially unsupported, with no tagged releases or paid support

Pick Swetrix if

• Fits if you want analytics, errors and flags in one cookieless tool
• Works for a developer who wants to self-host the free Community Edition

Look elsewhere if

• Skip it if you want a trial without a card, as it asks for a payment method
• Too light for session replays, feature flags or A/B testing on Standard
• Tight if you grow: price follows monthly events, counting pageviews, custom events and errors
• Watch out: the free Community Edition is self-hosted, so you run the servers

PostHog

• Usage is metered per product, so the monthly bill moves with traffic; billing limits can be set for each product to cap it.
• SSO enforcement, a HIPAA BAA and unlimited projects need the $250-a-month Boost package on top of usage; SAML sign-in needs Scale at $750.
• The free plan keeps recordings for 1 month and data for 1 year, allows 1 project, and drops events past its limits.
• Self-hosted PostHog is officially unsupported and has no tagged releases; PostHog recommends always running the latest image.

Swetrix

• The cloud service has no free plan; a payment method is needed even to start the 14-day trial.
• Price follows the monthly event count (pageviews, custom events and errors), from 100,000 up to 50 million.
• Session replays, feature flags and A/B testing are not on the Standard plan.
• The free Community Edition is self-hosted, so you run the servers yourself.

PostHog

Product and web analytics

Funnels, trends, retention, user paths and a web analytics dashboard, built from events. The first 1M events a month are free.

Session replay

Recordings of real visits to see where people get stuck, linked to funnels and errors. 5,000 recordings a month are free; recordings are kept 90 days on pay-as-you-go.

Feature flags and experiments

Roll features out to chosen users and run A/B tests, billed together by flag requests, with 1M requests free each month.

Surveys

In-app surveys with 1,500 free responses a month, and white-labeled surveys on the Boost package.

Error tracking and logs

Captures exceptions (100K free a month) and ingests logs (10 GB free), so you can go from a replay to the error behind it.

Data warehouse and pipelines

Syncs data in from Stripe, HubSpot, Salesforce, Postgres and others, and sends events out to tools such as Braze and Klaviyo.

Swetrix

Cookieless web analytics

Traffic, referrers, countries, devices and top pages in a real-time dashboard with no cookies and no data sampling.

Events, goals and funnels

Track custom events and conversion goals, then see where visitors drop off between steps in a funnel.

Performance and error tracking

Real-user page load timings and automatic JavaScript error capture, shown by page, browser and device.

Session replays

Recorded sessions with timelines of clicks and page changes. Replays are included from the Plus plan, not Standard.

Feature flags and A/B tests

Roll out features gradually and run experiments inside the same tool. Both need the Plus plan.

Search Console and alerts

Connect Google Search Console for queries and pages, and send alerts to email, Slack, Telegram, Discord or webhooks.
