| Deployment | FiloDB is deployed as standalone processes in a cluster and requires Java, Cassandra, Kafka, Rust, and a C compiler to build; SBT is also listed as a build prerequisite. | Self-hosted deployments can run at the edge, in containers or virtual machines, on local servers, or in public, private, or hybrid clouds. |
| Integrations | The README describes using FiloDB as a Grafana data source through its Prometheus-compatible HTTP API and identifies Cassandra as its persistence store. | The documented ecosystem includes Grafana integration, Kafka integration, MQTT, OPC, PI System and Excel connectivity. |
| License | The repository identifies Apache-2.0 as its license. | The TDengine TSDB open-source repository is licensed under GNU Affero General Public License version 3.0. |
| Support | The repository invites contributions; it does not state a paid support plan on the README page. | Annual licenses include business-hours standard support, while premium support offers 24×7 Severity 1 coverage; free-tier support is optional at $3,375 per year. |

In their own words
FiloDB
FiloDB is a free, Apache-2.0 open-source database for distributed, real-time time-series, event, and operational data. It is designed to ingest and query many millions of time series, sharding data across processes with distributed querying. Columnar compression and off-heap memory management support substantial in-memory storage while reducing garbage collection. PromQL is available through an HTTP API and command-line interface; the README describes support as about 60%. Histograms are a first-class column type, with the project reporting possible compression and query-speed improvements of up to two orders of magnitude. Typical ingestion uses Apache Kafka, while the Gateway accepts Influx Line Protocol over TCP. Grafana can connect through the Prometheus-compatible API, and Cassandra is identified as the persistence store. Deployment uses clustered standalone processes and requires Java, Cassandra, Kafka, Rust, a C compiler, and SBT to build.
TDengine
TDengine is an industrial data platform combining data ingestion, storage, analytics, modeling, visualization, and AI applications. Its two core components are TDengine TSDB and TDengine IDMP; TSDB is a distributed time-series database with built-in caching, stream processing, and data subscription. The platform connects to industrial sources including OPC, MQTT, and Kafka, and includes ETL for data cleaning and transformation. It offers a REST API described by OpenAPI, plus JDBC, ODBC, Kafka, MQTT, iframe embedding, and an Excel Add-In. Self-hosted deployments can run at the edge, in containers or virtual machines, on local servers, or in public, private, and hybrid clouds. Managed TDengine Cloud is offered on Amazon Web Services, Microsoft Azure, and Google Cloud Platform. TDengine TSDB-OSS is open source under AGPL and includes clustering. The self-hosted Free Tier covers up to 5,000 tags. Listed plans include Starter at $970 a month, a 7,500-tag self-hosted annual license at $12,500 a year, and a 7,500-tag self-hosted perpetual license at $31,250 as a one-time purchase.
