ThingsBoard vs OpenObserve: at a glance
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.
What is OpenObserve?
One release turns a telemetry store into synthetics, workflows, and AI observability.
v0.92.0 landed today after four release candidates, spanning 836 commits across the OSS and enterprise repositories. It adds three surfaces the product did not have — synthetic monitoring with private locations and agents, Workflows v1 tied to incidents, and an expanded AI observability set covering trace and session evaluations, an eval scheduler, organization AI credits, and an agent/service graph. Running alongside it, a 0.91.x maintenance branch has been taking small backported fixes on its own cadence.

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.
OpenObserve
6.3ANALYTICS
One release turns a telemetry store into synthetics, workflows, and AI observability.
◆ Current state
v0.92.0 landed today after four release candidates, spanning 836 commits across the OSS and enterprise repositories. It adds three surfaces the product did not have — synthetic monitoring with private locations and agents, Workflows v1 tied to incidents, and an expanded AI observability set covering trace and session evaluations, an eval scheduler, organization AI credits, and an agent/service graph. Running alongside it, a 0.91.x maintenance branch has been taking small backported fixes on its own cadence.
◆ Where it's heading
Scope is moving outward from storing and querying telemetry toward acting on it: alerting gained per-group and per-series rules with SLO measurement, incidents can be ingested from external alert sources, and Workflows connects automation to them. The second axis is observing AI systems rather than merely serving them, with evaluations and an agent graph now first-class. Moving Vortex and the MCP server into open source, the latter on the 2026-07-28 spec with OAuth 2.0 sign-in, points the same platform at agent clients as consumers of its data.
◆ Prediction
Expect a 0.92.x patch train within days — each of the last two GA releases drew several backport-only point releases — concentrated on the newly opened surfaces. The crate modularization noted in the release also makes a period of build and packaging fixes likely.
