What is Clair?
Clair 4.10 RC can read SBOMs to match Java vulnerabilities.
Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.
What is Novu?
Novu makes its workflows controllable by AI agents and by code, not just dashboards.
Novu's recent arc moves notification workflows out of a single editing surface. November introduced Contexts for multi-tenant scoping, January shipped Subscriptions plus a React Subscription component, April let any step run in Custom Code mode with CLI publishing, and the Novu MCP Server went GA in late April with 20+ tools covering subscribers, triggering, cancellation, and integrations. Slack chat is in private beta.
Clair vs Novu: editorial side-by-side
Clair
2.5INFRA · APIS
Clair 4.10 RC can read SBOMs to match Java vulnerabilities.
◆ Current state
Clair cut its first 4.10.0 release candidate on November 13, eleven months after 4.9.0. Its Java indexers can now read CycloneDX SBOM files and treat them as the source of truth, and Red Hat's VEX data now covers Maven advisories, so Java packages in Red Hat images can be matched. It also reduces memory use when many packages share a source package.
◆ Where it's heading
Since 4.8 Clair has moved from Red Hat's older OVAL data to VEX, and each release follows Red Hat's security data more closely. 4.10 adds SBOMs as an input, so Clair can match what an image's own manifest declares, not only what it finds on disk.
◆ Prediction
More 4.10 release candidates and then a final are likely; the long gap between releases suggests that could take weeks.
Novu
2.1INFRA · APIS
Novu makes its workflows controllable by AI agents and by code, not just dashboards.
◆ Current state
Novu's recent arc moves notification workflows out of a single editing surface. November introduced Contexts for multi-tenant scoping, January shipped Subscriptions plus a React Subscription component, April let any step run in Custom Code mode with CLI publishing, and the Novu MCP Server went GA in late April with 20+ tools covering subscribers, triggering, cancellation, and integrations. Slack chat is in private beta.
◆ Where it's heading
Novu is positioning as a notification platform an AI agent can drive end-to-end and a developer can wire from code, with the dashboard becoming optional. The MCP Server GA codifies that pitch publicly. Expect more tools exposed over MCP and continued depth on tenant scoping, since multi-tenant SaaS is the main buyer.
◆ Prediction
The next directional move likely formalizes agent-built workflows as first-class artifacts with versioning and approval, so AI-authored notifications can survive review. Slack and other chat integrations should leave beta and join the standard provider list.
