Fission vs Velociraptor
A side-by-side editorial comparison of Fission and Velociraptor — release velocity, themes, recent moves, and the top alternatives to consider.
Fission vs Velociraptor: 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 Velociraptor?
Velociraptor's recent releases are mostly about patching CVEs.
Velociraptor 0.77.3 shipped on October 5 as a bug fix and CVE release; it also adds an artifact that uploads server results to Azure Monitor and trims the columns emitted by the backup artifacts. 0.77.2 and a 0.76.7 backport in September and August were CVE fixes. The 0.77.1 feature release landed in June, but its notes in the feed only link out.

◆ 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.
Velociraptor
0.0INFRA · APIS
Velociraptor's recent releases are mostly about patching CVEs.
◆ Current state
Velociraptor 0.77.3 shipped on October 5 as a bug fix and CVE release; it also adds an artifact that uploads server results to Azure Monitor and trims the columns emitted by the backup artifacts. 0.77.2 and a 0.76.7 backport in September and August were CVE fixes. The 0.77.1 feature release landed in June, but its notes in the feed only link out.
◆ Where it's heading
Since June the project has been in security mode, fixing CVEs on the current line and backporting to the previous one. Feature work shows up as new artifacts, here an Azure Monitor export, which keeps Velociraptor feeding results into the logging tools teams already use.
◆ Prediction
Expect further 0.77 patch releases and possibly another backport if new CVEs are published; the timing of a 0.78 feature release is not signaled here.
