ThingsBoard vs ROOT
A side-by-side editorial comparison of ThingsBoard and ROOT — release velocity, themes, recent moves, and the top alternatives to consider.
ThingsBoard vs ROOT: 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 ROOT?
ROOT is shipping the pieces of its long-promised v7 inside the v6 release line
ROOT maintains an unusual number of parallel branches — patches for 6.26, 6.28, 6.30, 6.32, 6.36 and 6.38 all landed within weeks of each other in June 2026 — because CERN experiments pin to versions for years at a time. The 6.40 LTS released in May is where the actual work is: an opt-out from automatic object registration, experimental multithreaded histograms, a new RFile interface, an libcurl-based HTTP I/O layer with S3 support, and a rebuilt ML data loader. June's patch wave is the routine consequence, closing out the 6.26 and 6.38 series while fixing the first regressions in 6.40.

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.
ROOT

ROOT is shipping the pieces of its long-promised v7 inside the v6 release line
◆ Current state
ROOT maintains an unusual number of parallel branches — patches for 6.26, 6.28, 6.30, 6.32, 6.36 and 6.38 all landed within weeks of each other in June 2026 — because CERN experiments pin to versions for years at a time.

June's patch wave is the routine consequence, closing out the 6.26 and 6.38 series while fixing the first regressions in 6.40.
◆ Where it's heading
The ROOT 7 redesign is arriving piecemeal under ROOT::Experimental rather than as a version bump: RNTuple replacing TTree, RDataFrame replacing TTree::Draw, RFile replacing TFile, and now the ability to switch off the global-directory ownership model that has defined ROOT's ergonomics for decades. The team is easing migration with documentation rather than deprecation — 6.40 ships a TTree::Draw-to-RDataFrame translation guide instead of a removal notice. Build weight is being cut in the same pass, with bundled builtin packages reduced roughly fourfold in favour of system libraries.
◆ Prediction
Expect further 6.40.x patches through the year as experiments migrate onto the LTS, concentrated in RNTuple and the new histogram paths where the code is youngest. The experimental namespace is the thing to watch: features that stabilize there are the clearest available signal of what a ROOT 7 would actually contain.
