Amplitude vs Aptabase

Amplitude is a product analytics service with event tracking, conversion funnels, session recordings, and ecommerce tracking. It also provides API access and extended data retention. The platform is listed as API-based. Its Free plan costs nothing and includes up to 2M events per month, 10,000 monthly session replays, and 2,000 AI feedback records; it is billed free forever and requires no credit card. Plus is listed at free, with the first 2M events per month free and a credit card required. It supports up to 70M events, 20 behavioral cohorts, and two-year data retention. Amplitude, the maker, was founded in 2012 and is headquartered in San Francisco, California, United States.

Aptabase is an open-source analytics platform for mobile, desktop, and web apps. Its real-time dashboard shows sessions, events, app and operating system versions, devices, and countries. Developers define custom events and may attach string or number properties; Aptabase says it does not track anything automatically. It says it avoids device identifiers, cookies, fingerprints, and long-term user identification, so it cannot provide user-level measures such as monthly active users or per-user retention. Cloud data can be stored in Germany for the EU region or Virginia for the US region, and users can host their own servers. Customers own their analytics data, can export it to CSV, and data is retained for up to five years. Integrations include mobile and web frameworks, desktop app tools, browser extensions, game engines, Python, and C++. The server is licensed under AGPL-3.0 and SDKs under MIT. The free plan is free for up to 20,000 events per month across unlimited apps. Paid monthly plans start at $10 a month for 200,000 events.
