Prometheus Alertmanager vs Hatchet: 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 Hatchet?
Hatchet chases DAG crash loops through three engine patches in a day.
Hatchet added sandboxes, Labs switches and cloud MFA in early November. The week since has been engine reliability: v0.120.3 batches DAG step triggers, v0.120.4 fixes stranded match rows and prunes database partitions before locking, and v0.120.5 removes another cause of DAG crash loops. Python SDK 1.46.0 makes it easier to unit-test tasks and passes failures to cleanup dependencies.

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.
Hatchet
6.3INFRA · APIS
Hatchet chases DAG crash loops through three engine patches in a day.
◆ Current state
Hatchet added sandboxes, Labs switches and cloud MFA in early November. The week since has been engine reliability: v0.120.3 batches DAG step triggers, v0.120.4 fixes stranded match rows and prunes database partitions before locking, and v0.120.5 removes another cause of DAG crash loops. Python SDK 1.46.0 makes it easier to unit-test tasks and passes failures to cleanup dependencies.
◆ Where it's heading
After a burst of features, Hatchet is tuning the engine under load: fewer locks, batched triggers and crash-loop fixes. The SDKs are getting testing and correctness work to match.
◆ Prediction
Expect more v0.120.x patches on DAG handling, then a sandbox package out of release candidate.
