Huginn vs Windmill: at a glance
What is Huginn?
Huginn now waits three days before trusting a newly published gem.
Huginn has shipped near-weekly releases since August, starting with security fixes and moving into hardening and upkeep. The latest, v2026.11.01, updates bundled gems and adds a three-day cooldown before newly published gems are picked up during dependency resolution. The week before brought a Ruby 4.0.9 upgrade for a regex memory-corruption fix, a localized web UI and corrected CA trust after the eMudhra incident.
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.

Huginn
5.0INFRA · APIS
Huginn now waits three days before trusting a newly published gem.
◆ Current state
Huginn has shipped near-weekly releases since August, starting with security fixes and moving into hardening and upkeep. The latest, v2026.11.01, updates bundled gems and adds a three-day cooldown before newly published gems are picked up during dependency resolution. The week before brought a Ruby 4.0.9 upgrade for a regex memory-corruption fix, a localized web UI and corrected CA trust after the eMudhra incident.
◆ Where it's heading
After the August and September security advisories, the project has turned to supply-chain and runtime hygiene: trust stores, hardened CI runners and now a gem cooldown. Feature work is small and operator-facing, such as Agents page filters and the LOCALE setting.
◆ Prediction
More weekly maintenance releases are likely; the feed shows no sign of a larger feature push.
Windmill
5.0INFRA · APIS
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.
