Prometheus Alertmanager vs Velociraptor: at a glance
What is Prometheus Alertmanager?
Alertmanager 0.35 adds a gRPC API and a new UI, and breaks event recorder configs
Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.35.0 (November 9) is the largest release in the feed: an experimental ConnectRPC API (Connect, gRPC and gRPC-Web) beside api/v2, a new Mantine UI at /ui/, Slack thread replies for alert updates, and breaking changes that require named event recorder outputs, move its output to an events/v2 schema and promote auto-gomemlimit to a plain flag. It follows 0.34.2, which turned CORS off by default.
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.

Alertmanager 0.35 adds a gRPC API and a new UI, and breaks event recorder configs
◆ Current state
Alertmanager handles deduplication, grouping, silencing and routing of Prometheus alerts. 0.35.0 (November 9) is the largest release in the feed: an experimental ConnectRPC API (Connect, gRPC and gRPC-Web) beside api/v2, a new Mantine UI at /ui/, Slack thread replies for alert updates, and breaking changes that require named event recorder outputs, move its output to an events/v2 schema and promote auto-gomemlimit to a plain flag. It follows 0.34.2, which turned CORS off by default.
◆ Where it's heading
The project is replacing its interfaces in parallel rather than in place: a new API generation and a new UI now run alongside the old ones. The event recorder introduced in 0.33 is being reshaped with breaking schema changes, so anything consuming it is tracking a moving target.
◆ Prediction
Expect 0.35.x patch releases fixing fallout from the breaking changes, and further services added to the ConnectRPC API beyond the initial status service.
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.
