Routinator vs Windmill: at a glance
What is Routinator?
Routinator 0.16 will validate ASPA and BGPsec, and run strict, by default
Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. After a run of security work, including an external audit's four CVEs in 0.15.2 and resource-exhaustion fixes in 0.15.3, 0.16.0-rc1 changes defaults: ASPA and BGPsec are on, strict validation is on, and the old enable flags become --disable-aspa, --disable-bgpsec and --relaxed. It also adds Resource Signed Checklists (RFC 9323), SLURM v2 with ASPA filtering, and a new repository logging scheme that changes the /status JSON.
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.

Routinator 0.16 will validate ASPA and BGPsec, and run strict, by default
◆ Current state
Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. After a run of security work, including an external audit's four CVEs in 0.15.2 and resource-exhaustion fixes in 0.15.3, 0.16.0-rc1 changes defaults: ASPA and BGPsec are on, strict validation is on, and the old enable flags become --disable-aspa, --disable-bgpsec and --relaxed. It also adds Resource Signed Checklists (RFC 9323), SLURM v2 with ASPA filtering, and a new repository logging scheme that changes the /status JSON.
◆ Where it's heading
Having spent 2026 hardening the validator, the maintainers are now changing what operators get out of the box. Defaults moving toward ASPA and strictness put newer RPKI object types on equal footing with route origin validation.
◆ Prediction
A final 0.16.0 following one or more release candidates is the likely next step, as with 0.15.0.
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.
