Windmill vs Hatchet: at a glance
What is Windmill?
Windmill keeps turning AI clients into the place you build and run its workflows.
Windmill has spent the last six weeks wiring AI into every layer: standalone agents, compaction memory, an AI decision step, Slack-answering agents, and a single /api/mcp endpoint that lets Claude, ChatGPT or Cursor write, test and deploy workspace code. Alongside that it is formalizing who can do what, with default Developer and Operator roles and seat-priced operator build rights. The latest release, Tailwind v4 compilation for full-code apps, is frontend plumbing that makes those apps easier to style.
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.

Windmill keeps turning AI clients into the place you build and run its workflows.
◆ Current state
Windmill has spent the last six weeks wiring AI into every layer: standalone agents, compaction memory, an AI decision step, Slack-answering agents, and a single /api/mcp endpoint that lets Claude, ChatGPT or Cursor write, test and deploy workspace code. Alongside that it is formalizing who can do what, with default Developer and Operator roles and seat-priced operator build rights. The latest release, Tailwind v4 compilation for full-code apps, is frontend plumbing that makes those apps easier to style.
◆ Where it's heading
The direction is clear: Windmill wants to be the execution backend that AI clients drive, not just a UI people click through. MCP moved from a tool list to a build-and-deploy surface, then to interactive cards inside the chat. The roles and seat changes suggest it is preparing to price the wider set of people who can now build through AI.
◆ Prediction
Expect more of the deploy and review lifecycle to surface inside MCP clients, and finer-grained role controls over which MCP tools each role gets.
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.
