InfluxDB is a database built to collect, process, transform, and store event and time series data, and is ideal for use cases that require real-time ingest and fast query response times to build user interfaces, monitoring, and automation solutions.
[!Note]
What's my InfluxDB version?
With multiple InfluxDB deployment options available, identifying which one you're using is important for accessing the correct documentation and features.
Identify your InfluxDB version using:
- Interactive version detector
- URL pattern recognition
- Command-line tools
- HTTP API headers
Or browse the product lineup below to find yours.

Storage engine notes:
Product availability:
API compatibility:
v3 API: Latest API in InfluxDB 3 Core and Enterprise (/api/v3 endpoints) with database-based data model
v2 API: Used in InfluxDB v2 with token authentication and bucket-based data model; InfluxDB 3 products support /api/v2/write compatibility endpoint
v1 HTTP API: Legacy API with /write and /query endpoints; InfluxDB 3 products provide v1 compatibility for easier migration from v1 products

InfluxDB 3 is InfluxDB’s next generation that unlocks series limitations present in the Time Structured Merge Tree (TSM) storage engine and allows infinite series cardinality without any impact on overall database performance. It also brings with it native SQL support and improved InfluxQL performance.
InfluxDB 3 Explorer is the standalone web application designed for visualizing, querying, and managing your data stored in InfluxDB 3 Core and Enterprise.
Telegraf is a plugin-driven server agent for collecting and reporting metrics. It supports over 300 input and output plugins, including support for InfluxDB 3.

Legacy product - New InfluxDB Cloud signups use InfluxDB 3
InfluxDB Cloud (TSM) is a legacy managed service based on InfluxDB v2.x. New signups are no longer available. New InfluxDB Cloud signups are directed to InfluxDB Cloud Serverless (powered by InfluxDB 3).
Existing InfluxDB Cloud (TSM) customers should consider migrating to InfluxDB 3. If you are looking to use InfluxDB v2 (TSM), consider self-hosting InfluxDB OSS v2.
The InfluxDB 2 platform consolidates InfluxDB, Chronograf, and Kapacitor from the InfluxData 1.x platform into a single packaged solution, with added features and flexibility:
[!Note]
Integrate InfluxDB 2.0 applications with InfluxDB Enterprise 1.8+
Use InfluxDB 2.0 API compatibility endpoints to integrate applications built on InfluxDB 2.0 or InfluxDB Cloud with InfluxDB Enterprise 1.8+:
- Query data in InfluxDB Enterprise using
api/v2/queryand Flux.- Write data to InfluxDB Enterprise using
api/v2/write(compatible with InfluxDB 2.0 client libraries).
The InfluxDB 1.x platform provides time series data storage with the TICK stack (Telegraf, InfluxDB, Chronograf, Kapacitor).

Legacy product - New InfluxDB Cloud signups use InfluxDB 3
InfluxDB Cloud 1 (also known as InfluxCloud 1.x) is a legacy managed service based on InfluxDB Enterprise v1. New signups are no longer available. New InfluxDB Cloud signups are directed to InfluxDB Cloud Serverless (powered by InfluxDB 3).
Existing InfluxDB Cloud 1 customers should consider migrating to InfluxDB 3. If you are looking to use InfluxDB v1, consider self-hosting InfluxDB OSS v1.
InfluxDB Cloud 1 was a Database as a Service (DBaaS) offering that provided fully managed, production-ready InfluxDB Enterprise v1 clusters hosted on AWS. It was designed to collect, store, and process time series data without the operational overhead of managing infrastructure.
InfluxDB Enterprise, Cloud 1, and Cloud (TSM) customers can migrate to modern InfluxDB 3 products with improved performance, scalability, and features. Migration options include:
