What is Dragonfly?

Dragonfly speeds up slot lookups on 2.0 as its cluster-mode fixes keep coming.

Dragonfly maintains two incremental lines, 1.40 and 2.0, with small targeted releases. The 2.0 line has fixed dropped writes during slot migration and moved experimental slot-based sharding to Fibonacci hashing. i2.0.6 on October 30 makes GetSlotInfo faster, another cluster-mode refinement.

What is Windmill?

Windmill adds workspace roles and AI decision steps as its agent tooling fills out.

Windmill is an open-source workflow and internal-tools platform adding AI and governance features quickly. Mid-September brought a headless Chat SDK for chat-mode flows, per-run tool selection for AI agent steps, origin allowlists for HTTP routes, GitHub CI gating and GitLab git-sync parity. October added an AI decision step, operator builder rights and default Developer and Operator workspace roles.

Dragonfly vs Windmill: editorial side-by-side

D
Dragonfly
INFRA · APIS
5.0

Dragonfly speeds up slot lookups on 2.0 as its cluster-mode fixes keep coming.

◆ Current state

Dragonfly maintains two incremental lines, 1.40 and 2.0, with small targeted releases. The 2.0 line has fixed dropped writes during slot migration and moved experimental slot-based sharding to Fibonacci hashing. i2.0.6 on October 30 makes GetSlotInfo faster, another cluster-mode refinement.

◆ Where it's heading

The 2.0 line is maturing through cluster and migration work, while 1.40 gets targeted performance backports. Release cadence has slowed from paired weekly builds to occasional single fixes.

◆ Prediction

Expect further 2.0.x builds focused on cluster mode and slot migration; whether scope-based memory tracking gets switched on is still unclear.

Windmill

5.0

Windmill adds workspace roles and AI decision steps as its agent tooling fills out.

◆ Current state

Windmill is an open-source workflow and internal-tools platform adding AI and governance features quickly. Mid-September brought a headless Chat SDK for chat-mode flows, per-run tool selection for AI agent steps, origin allowlists for HTTP routes, GitHub CI gating and GitLab git-sync parity. October added an AI decision step, operator builder rights and default Developer and Operator workspace roles.

◆ Where it's heading

Windmill is building AI agents into flows as first-class steps with controls over which tools they can use, while adding the role and access model enterprises need to let more people build. Developer workflow parity across Git hosts continues in parallel.

◆ Prediction

Expect more AI agent controls and role-based permissions; whether the Chat SDK grows into a hosted chat product is unclear.
