These three tools all promise privacy-respecting, self-hostable analytics, but they optimize for different buyers. Aptabase is the leanest option, built for…
Freemium · From Free (up to 20,000 events/month)
Best for: Indie developers and small product teams who want simple, anonymous event analytics across mobile, desktop, and web apps with a generous free tier and no cookies or device fingerprinting.
Freemium / Subscription · From Free (Community Edition); Flex plans from $175/month
Best for: Product teams that want analytics, crash reporting, push notifications, and A/B testing bundled into a single platform and are willing to pay for a managed private-cloud or self-hosted Enterprise tier.
Freemium / Open Source · From Free
Best for: Engineering-led teams in regulated industries like healthcare, finance, or government that already operate a data warehouse and want GA4/Matomo-compatible ingestion with full data ownership rather than a vendor-controlled dashboard.

Aptabase optimizes for privacy and simplicity
Aptabase tracks events with no cookies, device fingerprints, or personal identifiers, and offers a free tier of up to 20,000 events per month with no overage fees, appealing to privacy-conscious indie and small-team developers.
Aptabase
Countly is the most full-featured platform
Countly combines session and event analytics with crash reporting, push notifications, remote configuration, A/B testing, and a Compliance Hub for consent management, a broader feature set than either Aptabase or d8a.tech document.
Countly
d8a.tech is warehouse-native, not dashboard-first
Unlike Aptabase and Countly, which ship their own analytics dashboards, d8a.tech writes a normalized schema directly into ClickHouse, BigQuery, or flat files, meaning value depends on connecting it to a separate BI tool like dbt, Looker, or Metabase.
d8a.tech
All three offer a genuinely free, self-hostable core
Aptabase, Countly (Community Edition), and d8a.tech (MIT-licensed) can all be self-hosted at no license cost, though only Aptabase and d8a.tech also offer a free managed cloud tier without any self-hosting required.

Maturity varies significantly
Countly was founded in 2012 and reports processing data for more than 5 billion identities across roughly 17,000 applications, while Aptabase (2023) and d8a.tech (2022) are newer projects, and d8a.tech's native web tracker is explicitly still in beta.

Aptabase, since it offers a free tier of up to 20,000 events per month with unlimited apps and no overage fees, aimed specifically at indie developers and small teams.
d8a.tech is purpose-built for this: it ingests events using the same GA4 Measurement Protocol and Matomo tracking API already in use, so existing tracking snippets can be redirected with minimal code changes.
Countly is the only one of the three that documents crash and error reporting alongside push notifications, remote configuration, and A/B testing.
d8a.tech does. Its core value depends on writing data into a warehouse like ClickHouse or BigQuery and then querying it with a separate BI or dashboard tool, whereas Aptabase and Countly both ship their own built-in dashboards.
Countly, founded in 2012, with a reported infrastructure processing data for more than 5 billion unique identities across roughly 17,000 applications. Aptabase (2023) and d8a.tech (2022) are considerably newer.
Aptabase is explicitly designed this way, with no cookies, device fingerprints, or personal identifiers used to track users. Countly and d8a.tech do not make the same anonymity-by-design claim in the available data.
