CloudQuery vs Device42

CloudQuery is an open-source context engine for cloud infrastructure that syncs data from more than 80 sources. It maps information from services such as AWS, GCP, Azure, GitHub, and Okta into a normalized relational schema that users can query with standard SQL. Data can be sent to destinations including Postgres, BigQuery, Snowflake, and S3. CloudQuery Platform supports more than 70 integrations and processes synced data into a built-in ClickHouse database for inventory, SQL Console, policies, and reports. An MCP server in PostgreSQL or Snowflake mode lets AI agents and internal systems query synced data without a Platform subscription. Sync definitions use version-controlled YAML, and SDKs in Go, Python, JavaScript, or Java can be used to build unsupported integrations. CloudQuery can run on infrastructure the user controls, keeping data within the network unless configured otherwise. Its Free plan costs nothing, billed Forever, with a 1M rows limitation. Pricing counts rows each time they are synced. The CLI is offered for macOS, Windows, and Linux.

Device42 provides agentless discovery, asset management, and dependency mapping for data center, cloud, and hybrid IT environments. Its scope includes CMDB, DCIM, ITAM, IPAM, password management, and application dependency mapping, in a self-hosted deployment. It can discover network devices through SNMP and cloud resources across AWS, Azure, Google Cloud, Oracle Cloud, and OpenStack.

For data centers, its visual models cover buildings, rooms, racks, cabling, and patch panels, with power and temperature heat maps. Core includes discovery, inventory and asset management, integrations, REST APIs and webhooks, warranty and SSL certificate management, cable and password management, and IPAM. Device42 also tracks software licenses, contracts, and barcodes, and lists more than 30 integrations. Licenses count devices with IP addresses; non-IP assets do not count, and user seats are unlimited. If the device limit is exceeded, the software keeps running but stops collecting additional information until the license is increased. Pricing is available on request, and a free trial is offered.
