Dagster vs ThingsBoard
A side-by-side editorial comparison of Dagster and ThingsBoard — release velocity, themes, recent moves, and the top alternatives to consider.
Dagster vs ThingsBoard: at a glance
What is Dagster?
Dagster's declarative automation grows past assets while the UI is rebuilt for scale.
Dagster ships weekly 1.13.x point releases, each pairing a short list of new capability with a longer list of fixes. The through-line is Declarative Automation, the asset-condition system that separates Dagster from schedule-driven orchestrators, which has now reached jobs. Running alongside it is a sustained effort to keep the UI responsive in workspaces whose asset graphs outgrew the original interface.
What is ThingsBoard?
An IoT platform whose release notes have become a CVE ledger
ThingsBoard ships every release twice — once on the 4.3 line and once as a 4.2 backport with an identical security section — and those security sections now dominate the notes, running to twenty or thirty CVEs per release. The recurring classes are telling: SSRF through AI model provider URLs, SSRF and file access escapes from the TBEL script sandbox, DNS rebinding bypasses, and access control on alarm comments. Feature work continues underneath, mostly IoT Hub integration and an Angular 20 UI migration.

Dagster
6.3ANALYTICS
Dagster's declarative automation grows past assets while the UI is rebuilt for scale.
◆ Current state
Dagster ships weekly 1.13.x point releases, each pairing a short list of new capability with a longer list of fixes. The through-line is Declarative Automation, the asset-condition system that separates Dagster from schedule-driven orchestrators, which has now reached jobs. Running alongside it is a sustained effort to keep the UI responsive in workspaces whose asset graphs outgrew the original interface.
◆ Where it's heading
Automation is escaping the asset boundary. Conditions can now launch jobs, which brings the declarative model to the parts of a deployment that never fit the asset abstraction and where users fell back to schedules. Several consecutive releases also spend their effort on virtualized lists, bounded previews and scoped search — the signature of a product whose largest customers hit the UI's limits first. Preview flags on both the job automation and the Snowflake component indicate neither is finished.
◆ Prediction
Expect Declarative Automation for jobs to move from preview to general availability within the 1.13.x line, and more first-party Components covering the remaining warehouse and dbt paths.
ThingsBoard

An IoT platform whose release notes have become a CVE ledger
◆ Current state
ThingsBoard ships every release twice — once on the 4.3 line and once as a 4.2 backport with an identical security section — and those security sections now dominate the notes, running to twenty or thirty CVEs per release. The recurring classes are telling: SSRF through AI model provider URLs, SSRF and file access escapes from the TBEL script sandbox, DNS rebinding bypasses, and access control on alarm comments. Feature work continues underneath, mostly IoT Hub integration and an Angular 20 UI migration.
◆ Where it's heading
The platform is paying down the security cost of being extensible. TBEL scripting and user-configurable AI model endpoints are exactly the features that make ThingsBoard useful for industrial rule engines, and both are repeatedly the source of sandbox and SSRF findings — so the work has shifted to fencing them with allow-lists, opt-in SSRF protection and configurable security headers. Meanwhile the AI surface keeps growing, with structured output support spreading across more model providers.
◆ Prediction
The dual-branch pattern will hold, with 4.2 continuing to receive the same security sets as 4.3 until it reaches end of life; expect further hardening of the TBEL sandbox rather than new scripting capability.
