ThingsBoard vs OpenMetadata
A side-by-side editorial comparison of ThingsBoard and OpenMetadata — release velocity, themes, recent moves, and the top alternatives to consider.
ThingsBoard vs OpenMetadata: at a glance
What is ThingsBoard?
ThingsBoard closes a script-sandbox file write and dozens of CVEs on its 4.3 and 4.2 lines.
ThingsBoard keeps three lines patched in parallel: 4.4, 4.3.1 and the 4.2 LTS. On October 27, 4.3.1.8 and 4.2.2.8 shipped a large security batch, including a fix for arbitrary file writes from the TBEL script sandbox and tamper protection for the OAuth2 authorization cookie. On October 30, 4.4.0.2 followed with security patches, though its notes list no details.
What is OpenMetadata?
OpenMetadata 2.0.8 widens Hex, Sigma and BigQuery coverage while 2.1 waits in release candidates.
OpenMetadata is still in 2.0.x maintenance mode, shipping a release every one to two weeks. 2.0.8 on November 13 is the broadest yet: Hex and Sigma ingestion now build data models and column lineage, BigQuery date-sharded tables can be grouped into one logical table, Power BI and Snowflake ingestion stop leaving stale or runaway jobs, and MCP authentication and access controls were tightened. The 2.1.0 line sits at rc2, whose only published change is a tag-resolution fix.
ThingsBoard vs OpenMetadata: editorial side-by-side
ThingsBoard
5.0ANALYTICS
ThingsBoard closes a script-sandbox file write and dozens of CVEs on its 4.3 and 4.2 lines.
◆ Current state
ThingsBoard keeps three lines patched in parallel: 4.4, 4.3.1 and the 4.2 LTS. On October 27, 4.3.1.8 and 4.2.2.8 shipped a large security batch, including a fix for arbitrary file writes from the TBEL script sandbox and tamper protection for the OAuth2 authorization cookie. On October 30, 4.4.0.2 followed with security patches, though its notes list no details.
◆ Where it's heading
After the 4.4 feature release the project is back to maintenance on all supported lines, mostly security and runtime fixes, with the IoT Hub catalogue getting steady UI work alongside. Feature work arrives in larger, infrequent releases.
◆ Prediction
Expect the next entries to be routine patches across all three lines. The notes do not say whether 4.4.0.2 carries the same fixes as the 4.3 batch.
OpenMetadata
5.0ANALYTICS
OpenMetadata 2.0.8 widens Hex, Sigma and BigQuery coverage while 2.1 waits in release candidates.
◆ Current state
OpenMetadata is still in 2.0.x maintenance mode, shipping a release every one to two weeks. 2.0.8 on November 13 is the broadest yet: Hex and Sigma ingestion now build data models and column lineage, BigQuery date-sharded tables can be grouped into one logical table, Power BI and Snowflake ingestion stop leaving stale or runaway jobs, and MCP authentication and access controls were tightened. The 2.1.0 line sits at rc2, whose only published change is a tag-resolution fix.
◆ Where it's heading
Each 2.0.x release repairs connectors and lineage that 2.0 left incomplete, and the fixes increasingly touch accuracy (correct table identity, lineage that ends at the right model) rather than crashes. MCP keeps appearing in the security sections, which suggests OpenMetadata expects AI tools to read the catalog and is locking that path down before 2.1.
◆ Prediction
A 2.1.0 final is the next visible step, since two release candidates are out; the entries do not yet say what features 2.1 adds beyond the fixes backported to 2.0.x.
