Choose SensorFlow if you want a focused, self-managed route from compatible Sensors Data SDKs into ClickHouse, with Apache Superset for analysis. Choose Countly if you want a product analytics application and its integrated services: in Countly 26.01, event data flows through Kafka to ClickHouse, while MongoDB supports operational data and common precomputed metrics. Neither option eliminates infrastructure work when self-hosted; the main difference is whether you want to operate a narrower analytics stack or adopt Countly’s broader application architecture.
Analytics application or SDK-to-ClickHouse pipeline?
The choice is not simply between an application and a database pipeline: Countly 26.01 also uses ClickHouse in its event architecture. The practical distinction is what you want to own and use day to day. SensorFlow documents a focused SDK-to-ClickHouse stack with Superset; Countly provides its own application and query layer across several services.

How each system handles events
SensorFlow: SDKs, receiving service, ClickHouse, and Superset
SensorFlow’s documented design routes supported Sensors Data SDK events through SensorFlow before storing them in ClickHouse for analysis with Superset. Its feature page lists data validation, user identification, custom properties, and SQL analysis as capabilities. These are vendor-described features, not independently tested findings.

What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
SensorFlow presents itself as open-source and self-hosted, with customers keeping data on infrastructure they manage. Its quick start describes a local demo that requires no registration or license, but says production SDK ingestion requires a license. The product page lists a deployment license starting at USD 349 per year, with hosting and operations separate; this is a vendor-stated price seen October 7, 2026, so confirm current terms with SensorFlow.

Countly 26.01: event pipeline plus application services
In Countly’s documented 26.01 design, the Ingestor accepts SDK events and sends them to Kafka. Kafka Connect moves detailed event data to ClickHouse, while the Aggregator builds common product metrics in MongoDB. Countly also describes separate API, job-server, and frontend responsibilities, with a query layer selecting the appropriate store while retaining the product experience. Countly architecture
Countly says this architecture is designed for more than 100 billion data points and describes potential performance improvements of up to 100×. Those are Countly’s own claims about its design and potential performance, not independent, cross-product benchmark results or a guarantee for a particular deployment. Countly architecture

Can I send my Sensors Data SDK events to ClickHouse?
SensorFlow’s migration guidance says to direct standard SDK events to a compatible receiving service rather than connect client SDKs straight to ClickHouse. In this documented approach, SensorFlow receives and processes events before they reach ClickHouse. SensorFlow migration guide

SensorFlow suggests dual writing or moving a small share of traffic first to reduce cutover risk. Treat these as implementation recommendations, not proof that a particular migration has been tested.
Which option fits your setup?
Consider SensorFlow when
- Your product already uses compatible official Sensors Data SDKs, or you are prepared to instrument them.
- You prefer ClickHouse SQL and Superset to a dedicated analytics application interface.
- You can operate the infrastructure, backups, access controls, and compliance configuration yourself.
- You want to evaluate the local demo before deciding whether production ingestion and its license fit your needs.
Consider Countly when
- You want an analytics application with its own frontend and query layer rather than assembling the user-facing experience around Superset.
- You prefer Countly’s documented split between ClickHouse event analysis and MongoDB-backed operational and aggregated data.
- You can run and maintain the required services, or have confirmed the deployment and support terms for the edition you plan to use.
- You are already on Countly and want to understand the v26.01 data-store change before upgrading.
Both choices demand decisions about deployment ownership and operations. SensorFlow’s product documentation is explicit that customers manage their infrastructure; Countly describes component scaling, but the exact operational commitment depends on the edition and deployment arrangement.
Migration and cutover considerations
Moving SDK events to SensorFlow
- Confirm that the SDKs in use are compatible with SensorFlow’s receiving service. SensorFlow lists web, mobile, mini-app, and server SDK support. SensorFlow features
- Map event identity, properties and their types, and event-time semantics before sending production traffic.
- Define failure handling and how you will verify that events are accepted and represented as expected.
- Reduce cutover risk by considering dual writing or a small traffic share, as SensorFlow recommends. SensorFlow migration guide
Upgrading an existing Countly deployment to v26.01
Countly’s migration guide says v26.01 stores raw events in ClickHouse rather than MongoDB. MongoDB continues to hold operational data, metadata, and aggregated dashboard data. Deployments on v25.x and earlier therefore have raw event history to migrate; follow Countly’s current migration steps and pay attention to cutover sequencing and the configuration choice, since Countly warns that an incorrect choice can duplicate data.

Countly’s stated scale and potential performance gains are vendor-reported design claims. They do not establish that Countly is faster than SensorFlow, or predict performance for a particular workload. The available documentation does not provide an independent, head-to-head benchmark for these products. Plan capacity around your event volume, query patterns, retention needs, and operating environment rather than treating a headline figure as a deployment guarantee. Countly architecture
