Hatchet vs Scalar
A side-by-side editorial comparison of Hatchet and Scalar — release velocity, themes, recent moves, and the top alternatives to consider.
Hatchet vs Scalar: at a glance
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.
What is Scalar?
Scalar's Agent Chat now asks before every API call and hides your saved keys.
Scalar ships several package lines on separate version tracks. The November 10 batch makes the API client's Agent Chat ask for approval before any AI-generated request, including GETs, and redacts saved credentials before responses reach the model. The API reference 1.78 renders Avro, RAML and Protobuf schemas in AsyncAPI messages, the ASP.NET Core integration adds multipart file controls and OpenID Connect defaults, and the mock server fixes decimal and nested-response bugs.

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.
Scalar
5.0INFRA · APIS
Scalar's Agent Chat now asks before every API call and hides your saved keys.
◆ Current state
Scalar ships several package lines on separate version tracks. The November 10 batch makes the API client's Agent Chat ask for approval before any AI-generated request, including GETs, and redacts saved credentials before responses reach the model. The API reference 1.78 renders Avro, RAML and Protobuf schemas in AsyncAPI messages, the ASP.NET Core integration adds multipart file controls and OpenID Connect defaults, and the mock server fixes decimal and nested-response bugs.
◆ Where it's heading
Releases alternate between broader spec coverage (AsyncAPI schema formats, OpenAPI 3.2 details) and safety rails around automated actions, from the hardened CORS proxy to confirmation prompts in generated CLIs and now approval-gated Agent Chat.
◆ Prediction
Expect more guardrails on agent-driven requests and further AsyncAPI rendering work in the reference, shipped as small parallel releases.
