InfluxDB vs TDengine: key differences

Every row cites the vendor's own pages

Both are open-source time-series databases used for plant and sensor data, but the open-source deal and the pricing unit differ. InfluxDB 3 Core is permissively licensed (MIT or Apache-2.0) and single-node, with HA and clustering in the CPU-priced Enterprise edition. TDengine's open-source core is AGPL-3.0 and includes clustering; its commercial All-in-One adds industrial connectors and a data platform, priced by tag count and free up to 5,000 tags.

TopicInfluxDBTDengine
Open-source license[3, 8, 9]InfluxDB 3 Core: MIT or Apache-2.0, at the user's choice.TDengine OSS: AGPL-3.0 (copyleft).
What's open[1, 2, 9]Core is single node with no HA; high availability, read replicas, historical query capability and single-series indexing are Enterprise additions.Full-featured database including clustering; Enterprise and Cloud are built on the same code base.
Commercial pricing[2, 7]Enterprise custom-priced by CPU configuration (30-day trial); Cloud Dedicated custom-priced.All-in-One priced by tag count: free to 5,000 tags; 10,000 tags US$15,500/year or US$38,750 perpetual; HA +30%.
Managed cloud[2, 7]Cloud Serverless (usage-based), Cloud Dedicated, or Amazon Timestream for InfluxDB.TDengine Cloud on AWS, Azure or Google Cloud, from US$970/month for 5,000 tags.
Querying[1, 11]Built for fast recent-data queries (under 10 ms for last-value queries); SQL editor in InfluxDB 3 Explorer.SQL extended for time series: interpolation, downsampling and time-weighted averages.
Plant-floor collection[4, 5, 6, 7]Via InfluxData's Telegraf agent (400+ plugins), with OPC UA and MQTT input plugins.Zero-code connectors for MQTT, Kafka, OPC and PI System in the commercial plans.
Built-in processing[1, 8]Embedded Python VM for plugins and triggers.Caching, stream processing, Kafka-like data subscription and the TDgpt AI agent.
Platforms[2, 8, 10]Core runs on Linux, macOS and Docker.Packages for Linux and Windows; Docker and Kubernetes.

Consider InfluxDB when…

  • You want a permissive MIT/Apache license and a large ecosystem around Telegraf, and you can live with a single node or pay for Enterprise HA.
  • You prefer usage-based cloud pricing or AWS-managed Timestream for InfluxDB.

Consider TDengine when…

  • You want clustering in the open-source edition and are comfortable with AGPL-3.0 obligations.
  • You want historian-style tag-count pricing with OPC, MQTT and PI System connectors in the box.
