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 SavvyCal?
SavvyCal lets Claude or ChatGPT book and move meetings through an MCP server on every plan.
SavvyCal ships about once a month, and its latest release is the largest in a year: an MCP server on every plan that lets AI assistants find times, book or move meetings, block time and run polls. Earlier releases were contained refinements such as duplicating workflows, locking links before an event, per-event buffers and multi-language booking pages.

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.
SavvyCal
2.5INFRA · APIS
SavvyCal lets Claude or ChatGPT book and move meetings through an MCP server on every plan.
◆ Current state
SavvyCal ships about once a month, and its latest release is the largest in a year: an MCP server on every plan that lets AI assistants find times, book or move meetings, block time and run polls. Earlier releases were contained refinements such as duplicating workflows, locking links before an event, per-event buffers and multi-language booking pages.
◆ Where it's heading
For most of the year SavvyCal has added control for hosts and assistants who schedule for others. The MCP server extends that to software assistants: the same booking and rescheduling actions now work from a chat. That puts SavvyCal's scheduling logic inside other tools instead of only on its booking pages.
◆ Prediction
Expect follow-ups that widen what the MCP server can do, such as more scheduling actions. The single release gives little else to predict from.
