Community FAQ
Amplitude FAQ
Amplitude is offered primarily as a SaaS platform and does not provide a self-hosted version. All data processing and storage occur on Amplitude's cloud infrastructure, so teams requiring on-premise deployment will need to consider alternative analytics solutions or hybrid approaches.
Community insight informed by Reddit discussions
Amplitude SDKs support offline event queuing on client devices. Events generated while offline are stored locally and automatically sent to Amplitude servers once connectivity is restored, ensuring no data loss in typical mobile or web offline scenarios.
Community insight informed by StackOverflow discussions
Customers retain full ownership of their data in Amplitude. The platform acts as a data processor and complies with enterprise-grade security and privacy standards, including GDPR. Data export and deletion requests can be managed via the Amplitude dashboard or API to ensure compliance.
Community insight informed by Hacker News discussions
Amplitude’s Export API has rate limits and pagination constraints that can impact large data exports. For high-volume exports, Amplitude recommends using their Bulk Export feature or integrating with their data warehouse connectors (e.g., Snowflake, Redshift) to efficiently access raw event data without hitting API throttling.
Community insight informed by Forums discussions
Migrating from Mixpanel to Amplitude requires exporting raw event data from Mixpanel (usually via their export API) and then importing it into Amplitude using their HTTP API or Bulk Import tools. While feasible, the process involves careful mapping of event schemas and user identifiers to maintain data integrity and continuity.

PostHog FAQ
Self-hosting PostHog requires managing a multi-service stack including the database (Postgres), Kafka or Redis for event ingestion, and the PostHog application itself. While the official Helm charts and Docker Compose setups simplify deployment, you still need to handle scaling, backups, and updates manually. For small startups without dedicated DevOps, using PostHog Cloud or a managed service might be easier initially, but the open-source self-hosted option is feasible with basic Kubernetes or Docker knowledge.
Community insight informed by Reddit discussions
PostHog does not natively support offline data collection or edge caching out of the box. Events are sent directly from the client to the PostHog ingestion API in real-time. For scenarios requiring offline support, you would need to implement custom buffering on the client side and batch send events when connectivity is restored. This is not a built-in feature and requires additional development effort.
Community insight informed by Hacker News discussions
When self-hosted, all event data, session recordings, feature flags, and survey responses are stored within your own infrastructure, giving you full control over data ownership and privacy. PostHog does not send data to third parties by default. You can configure data retention policies and encryption at rest depending on your infrastructure setup. This makes it suitable for teams with strict compliance requirements.
Community insight informed by StackOverflow discussions
PostHog's API is designed to be scalable and API-first, but when self-hosted, rate limits depend on your infrastructure capacity rather than enforced hard limits. The cloud version enforces rate limits to protect service stability. For self-hosted deployments, you should monitor throughput and scale components like Kafka and Postgres accordingly to handle your event volume. Feature flag APIs support real-time updates but large-scale flag evaluations might require tuning for performance.
Community insight informed by Reddit discussions
PostHog supports exporting raw event data directly from its Postgres database or via its API. You can use SQL queries or the export endpoints to extract event streams in JSON or CSV formats. For migration, it's recommended to export data regularly and transform it to your target system's format. There is no built-in one-click migration tool, so custom scripts or ETL pipelines are typically used.
