Fission vs NetBox
A side-by-side editorial comparison of Fission and NetBox — release velocity, themes, recent moves, and the top alternatives to consider.
Fission vs NetBox: at a glance
What is Fission?
Fission's release feed carries only RC tags, and none of them say what shipped
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.
What is NetBox?
NetBox adds a cooling data model — the first new infrastructure domain since power
After a 4.6 patch cycle spent almost entirely on GraphQL query cost and permission correctness, NetBox has opened its 4.7 line with a beta that is the opposite kind of release. It introduces cooling infrastructure as a first-class modeling domain, migrates nested group models off django-mptt onto a PostgreSQL ltree column, replaces the Service protocol/ports fields with a unified port_mappings structure, and raises the floor to PostgreSQL 15 and Redis 6. The breaking-change list runs longer than most NetBox releases run in total.

◆ Current state
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.
◆ Where it's heading
What can be read from these tags is infrastructure maintenance rather than product direction: Go dependency updates, helm and kind and skaffold and cosign version refreshes, and regenerated swagger and applyconfiguration files kept in sync with CEL and webhook validation comments in the core API types. That last one is the only entry hinting at anything structural — CEL-based validation on the API types implies declarative validation moving into the CRDs — but the commit itself changes only generated output.
◆ Prediction
This feed does not carry enough to predict product direction; until final releases or their notes appear here rather than only candidate tags, any read of where Fission is heading would be guesswork.

NetBox adds a cooling data model — the first new infrastructure domain since power
◆ Current state
After a 4.6 patch cycle spent almost entirely on GraphQL query cost and permission correctness, NetBox has opened its 4.7 line with a beta that is the opposite kind of release. It introduces cooling infrastructure as a first-class modeling domain, migrates nested group models off django-mptt onto a PostgreSQL ltree column, replaces the Service protocol/ports fields with a unified port_mappings structure, and raises the floor to PostgreSQL 15 and Redis 6. The breaking-change list runs longer than most NetBox releases run in total.
◆ Where it's heading
The cooling model is deliberately shaped as a mirror of the existing power model — CoolingSource and CoolingFeed parallel PowerPanel and PowerFeed, CoolingIntake and CoolingOutflow parallel PowerPort and PowerOutlet, with CDUs and manifolds modeled as ordinary devices carrying those components. That symmetry says NetBox intends liquid cooling to be documented with the same rigor as power distribution, not bolted on as attributes. Underneath it, the ltree migration and the deferred search-index rebuild continue the performance thread of 4.6 by other means: instead of trimming queries inside the ORM, 4.7 is changing what the ORM sits on.
◆ Prediction
Expect at least one more 4.7 beta or release candidate before general availability, with the deprecated NestedGroupModel base class and the retained protocol/ports API fields the most likely sources of follow-up fixes as plugins migrate.
