Howdevelopersbuildsuccessfulproducts
The single platform to analyze, test, observe, and deploy new features
These folks build products users want with
8+ products in one
Trade in your product & data stack for a single platform –
 where everything is built to work together.
Product engineering has never been so lit.
SDKs for web and mobile
Web (frontend)
Use autocapture to collect client-side events without any special instrumentation.
Server-side libraries
Capture server-side events - best used in conjunction with a frontend web library
Mobile libraries
Send custom events and identify users. Record mobile sessions and use feature flags.
Mmmm, code examples
Here's what you can do with the PostHog JS code snippet and your product.
Warning: You'll hate PostHog if...
- You enjoy "jumping on a quick call" with sales- Sorry, we don't force you to talk to anyone. But you can watch a recorded demo (at your own pace) or request a personalized demo if you like. 
- You love needlessly wasting company money- We only have usage-based pricing that decreases exponentially with scale. 
- You'd rather buy before you try- We offer a free tier so large that only a fraction of our customers pay us anything. Even worse, we continually try to reduce our pricing. 
- You think your email is a good trade for that free whitepaper- Please press Ctrl + W now, or ask your network administrator to close your window. 
- You give out your credit card details to strangers- You'd rather buy a product you've never used instead of a generous free trial? 
- You're desperate for commitment- Sadly, we don't offer annual contracts (unless you ask for one). 
- You loathe new features, and bug fixes- Unfortunately we release new updates weekly. 
- You'd rather buy disparate tools and mangle them together- Apologies. Our focus is for you to engineer your product, not your data. 
- You like buying a whole product suite to get access to one tool- Alas we don't force people to buy stuff they don't use. We suit people who want to pay by product. 
- You think CSMs are your friends- Honey, those emails are automated. 
- You enjoy sitting through hours of training more than using the product- No training is required to use PostHog, though we have plenty of docs and guides if you need some guidance. 
- Data privacy isn't a big deal to you. (GDP-what now?)- Get cookie-less tracking, regional hosting, and raw database access. 
- Networking events are your things- We put on an event once. It was a disaster. Never again. 
- You love being out of the loop- We publish our roadmap, strategy, and company handbook. 
- Your CRM is a Rolodex- We don't even use phones, though we do have a fax number for legal and compliance reasons. 
API
We built PostHog on our API. This means you get full access to anything you want with your event and customer data that's ingested by PostHog. Here are some examples.:
- feature_flagsEvaluate feature flags from anywhereIf you don't use one of our SDKs, you can get a flag status for a user from the API on-the-fly. 
- insightsPull basic site stats from saved insightsShow stats like active users, pageviews, or number of daily signups (like we use near the bottom of this page!). 
- insightsUser-facing analyticsBuild your own visualizations of insights within your own app or internal dashboard. 
- personsRead/write user properties and display in your appUse PostHog as an external database by storing/reading user data and showing it in their user profile. 
- cohortsAdd high-value users to a cohortIf you're running Clearbit on new signups, you can automatically add them to a cohort based on criteria from enrichment services. 
- annotationsNotate when a feature is releasedAnnotations are useful for understanding inflection points in insights. You can programmatically create annotations like when a PR is merged. 
HogQL
HogQL is our translation layer over ClickHouse SQL. Use HogQL expressions to use JOINs and subqueries, filter event lists, and write complex queries (that aren't supported by the PostHog UI) to analyze data in any way you want.
For example...
- Double (or even triple?) breakdowns - concat(properties.name,' ; ',properties.$current_url)
- Advanced date filtering, relative times, weekly/monthly reports 
- Custom SQL insights directly accessing data 
- Custom scoring or "group/bin" events 
- NPS score, superhuman score calculations 
- Access JSON, object, list data
