PostHog vs TelemetryDeck (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 TelemetryDeck if

• Fits if you ship an app and want analytics without tracking users
• Works for indie developers under 50,000 events a month

Look elsewhere if

• Tight if you need real-time data on free, as events process between hourly and daily
• Watch out: prices are in euros and only the Indie step is readable, with higher tiers up to 15,000,000 events
• Watch out: annual billing is pre-selected, and monthly plans are not refunded
• Watch out: the pricing page text would not load here, so the prices are from the listing

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.

TelemetryDeck

• Prices are in euros and the dollar price was not shown.
• The Free plan has no real-time data, and events are processed between once an hour and once a day.
• Only the Indie step (€9 for 750,000 events) was readable; higher self-service tiers go up to 15,000,000 events and are chosen with a slider.
• Annual billing is pre-selected and saves 20%; the annual refund window is 14 days and monthly plans are not refunded.

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.

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.

TelemetryDeck
