| Deployment | The installation guide provides a Docker command for running the community image. | The server can be installed from a Debian package, compiled on Linux or OSX, or run with Docker. |
| Integrations | The ecosystem integration page lists LangChain, Grafana, Jaeger, Kafka, Prometheus, Telegraf, TensorFlow, and Vector. | The maker lists a Grafana data source plugin and native connectors for C/C++, Python, Go, and Node.js. |
| License | The official site says the standalone, distributed, and ecosystem tools use the AGPL-3.0 open-source license. | The multi-node clustering version is available as open source under the MIT license. |
| Product | CnosDB is an open-source distributed time-series database designed for high performance, compression, and ease of use. | SiriDB is an open-source time-series database for analyzing and aggregating time-series data from sources including IoT and financial transactions. |
| Querying | CnosDB supports standard SQL and time-based aggregation queries. | Its custom query language supports dynamic grouping of time series and distributed queries across pools. |
| Scaling | The architecture page says compute and storage nodes can scale capacity independently. | Pools can be added while SiriDB is running, and data is divided evenly across available pools. |
| Security | The configuration documentation provides optional TLS certificate and private key settings. | The HTTP API documentation describes basic authentication, while the SiriDB HTTP connector page says it supports SSL. |

In their own words
CnosDB
CnosDB is an open-source distributed time-series database for workloads such as IoT, industrial internet, connected vehicles, and IT operations. It supports standard SQL, time-based aggregation, and a DataFrame API. Data can be written without a predefined schema, including out of order, and historical data can be replenished. Ingestion methods include SQL, Line Protocol, OpenTSDB, Elasticsearch bulk, Loki, NDJSON, and OpenTelemetry. Deployment options include standalone, distributed, and storage-compute separated modes, on public, private, or hybrid clouds. The documentation describes horizontal scaling for storage and stateless compute nodes. Integrations include Grafana, Prometheus, Telegraf, JDBC, and a Python SDK; the open-source Python connector provides a PEP 249 interface for SQLAlchemy and pandas. Import and export formats include PARQUET, CSV, and JSON with AWS S3, Google Cloud Storage, and Azure Blob Storage. CnosDB documents retention policies, multi-tenancy, and role-based permissions, as well as optional TLS certificate and private-key settings. Community Edition is free under AGPL-3.0.
