PostHog

PostHog combines tools for product development, customer communication, and understanding customer data. Its analytics suite covers product and web analytics, funnels, heatmaps, graphs and trends, lifecycle analysis, and user paths. Session Replay records sessions from web, React Native, iOS, Android, Flutter, and other SDKs. Feature Flags can target users, groups, or traffic percentages and support phased rollouts, kill switches, multivariate variants, JSON payloads, and beta opt-ins. The platform also includes an integrated data warehouse, which can connect external data sources such as Snowflake or BigQuery. PostHog CDP transforms events in real time and routes them to more than 50 destinations, including webhooks, Slack, Braze, and Customer.io. PostHog Desktop is a coding agent that can use product signals to investigate causes and create pull requests. The free plan includes one year of event and metadata retention and one month of recording retention; paid plans guarantee seven years of event and metadata retention. PostHog also describes an MIT-licensed open-source product.

PostHog brings product analytics, replay, feature flags, and data tools together. Readers should note that free-plan retention is shorter than the seven-year guarantee on paid plans.

PostHog may suit product teams seeking analytics, session replay, feature flags, and data routing in one platform. Its desktop coding agent may also be relevant to developers investigating product issues.

PostHog is a product-building platform that combines analytics, session replay, feature flags, and customer-data tools. It suits teams building web and mobile products that want those capabilities together. Its breadth is compelling, but the free plan’s recordings last only one month.

Overview

PostHog spans product and web analytics, release controls, event routing, and data storage. That makes it a practical option for teams connecting product usage to rollout decisions and customer-data workflows; teams seeking only a narrow analytics tool may find its wider scope unnecessary. Its product suite includes an open-source product licensed under MIT.

PostHog was founded in San Francisco in 2020. Its Trust Center lists SOC 2, GDPR, CCPA, and HIPAA compliance, and says its products are covered by an independently audited SOC 2 Type II report. Security controls include audit logging, multi-factor authentication, encryption at rest and in transit, backups, and application penetration testing.

Key features

Analytics and replay

Event tracking, conversion funnels, heatmaps, trends, lifecycle analysis, and user paths cover both broad usage patterns and movement through journeys. Session Replay adds individual session context across web, React Native, iOS, Android, Flutter, and other SDKs. This combination is useful when teams need to investigate behavior as well as measure it, though free-plan recordings are retained for just one month.

Feature flags and data tools

Feature Flags can target users, groups, or traffic percentages, with phased rollouts, kill switches, variants, JSON payloads, and beta opt-ins. These controls make PostHog relevant to teams that want product measurement close to release management. Its CDP transforms events in real time and routes them to more than 50 destinations, including webhooks, Slack, Braze, and Customer.io. An integrated data warehouse and connections to Snowflake or BigQuery give teams options for working with customer data, although the range may be more than a small team needs.

PostHog Desktop

PostHog Desktop is a coding agent for macOS, Windows, and Linux. It can use product signals such as errors, support tickets, session replays, GitHub issues, Linear, and Zendesk to investigate causes and create pull requests. That makes it a distinctive addition for development teams already using those signals; it is not a reason to choose PostHog if analytics and product data are not central to the work.

Pricing

Free

The Free plan costs nothing, billed monthly, and requires no credit card. It includes 1M analytics events, 5K session recordings, 1M feature-flag requests, 100K exceptions, 1,500 survey responses, and 1M warehouse rows. Community support and one-year retention for events and metadata suit evaluation or smaller workloads, but the recording limit and one-month recording retention make it a weaker fit for teams that need longer replay history.

Pay-as-you-go Analytics

Pay-as-you-go Analytics has custom pricing. It includes 1M free analytics events per month, six projects, and seven-year data retention. It is the more focused paid option for teams prioritizing analytics and longer retention, but it does not publish a price in the plan details.

Pay-as-you-go

Pay-as-you-go has custom pricing and usage-based billing once a month. It includes unlimited usage, six projects, seven-year data retention, and email support. The stated allowance avoids a fixed usage ceiling, while usage-based billing means costs depend on consumption. Slack support is available to customers spending over $2,000 per month. Paid plans guarantee seven-year retention for events and metadata, compared with one year on Free.

There is no free trial. Free includes community support; email support comes with Pay-as-you-go, and the higher-spend Slack support threshold is worth noting for teams that expect to rely on direct help.

Platforms

PostHog supports Android, iOS, Linux, macOS, Windows, web, API, and self-hosted deployments. PostHog Desktop is available for Apple Silicon and Intel Macs, Windows, and Linux packages including AppImage, .deb, and .rpm. This breadth suits teams with mixed development environments and mobile products.

Who it's for

PostHog is strongest for product and engineering teams that want analytics, replay, feature flags, and customer-data tools in one platform, particularly across web and mobile. Free can cover initial usage within its published quotas. Teams that need longer event history or support beyond the community should weigh the paid plans, while those who need only basic analytics may prefer a more focused product.

Pros and cons

• Broad product toolkit: Analytics, replay, feature flags, event routing, and a warehouse can connect product insight with action.
• Useful release controls: Targeting, phased rollouts, and kill switches support controlled feature releases.
• Free entry point: The no-card plan includes meaningful event, replay, flag, and warehouse quotas.
• Short free retention: Events and metadata last one year, and recordings one month, on Free; paid plans guarantee seven years for events and metadata.
• Usage-based paid billing: Pay-as-you-go avoids a stated usage cap but requires teams to account for consumption, and its price is custom.

Alternatives

Web analytics tools are a useful category to compare when the priority is web measurement. For product-focused comparisons, see Product Analytics Tools, Customer Analytics Software, and Mobile App Analytics Software.

Zoho Apptics is another freemium option, with a free plan and trial. OpenPanel also has a free plan and trial, and offers a 5K-events-per-month plan for $2.50 a month. Pug is a free option with an open-source plan that includes unlimited events and projects. Matomo offers a free community plan with unlimited users and hits. Mixpanel has a free plan with unlimited seats and 1M events per month. Amplitude has a free plan with 2M events per month. Heap offers a free plan with 10,000 monthly sessions and six months of data history. Contentsquare has a free plan with 10K monthly sessions and seven months of data access.

Verdict

Choose PostHog if your product team wants analytics, replay, release controls, and customer-data tooling in one place, with broad platform support. Its main advantage is how those capabilities fit together; look elsewhere if you need only focused analytics or longer replay retention on a free plan.
