Home Assistant vs Windmill: at a glance
What is Home Assistant?
Home Assistant is systematically removing the technical knowledge its own product used to require.
Home Assistant ships monthly, and the last five releases read as one campaign: strip out the prerequisites that made the product feel like infrastructure. 2026.7 made purpose-specific automation triggers the default for everyone, so you describe what your home should do instead of which entity changes state. 2026.8 went further and removed the :8123 port from new installations, moved web server configuration out of YAML into the interface, and deleted the words advanced and expert from roughly 43 places. The capability surface is not shrinking; the vocabulary required to reach it is.
What is Windmill?
Windmill gives its AI agents a test harness, the piece that lets them into production flows
Windmill is a developer platform for scripts, flows and internal apps, shipping weekly across three lanes. The AI lane is the busiest: sessions that build scripts and flows as reviewable drafts, a read-only plan mode that refuses writes until you approve, version history on session artifacts, and now evaluation for reusable agents. The runtime lane keeps absorbing data tooling — dbt projects run natively, BigQuery and Snowflake came out from behind the Enterprise licence. The workspace lane is consolidating deployment semantics around fork lineage.

Home Assistant is systematically removing the technical knowledge its own product used to require.
◆ Current state
Home Assistant ships monthly, and the last five releases read as one campaign: strip out the prerequisites that made the product feel like infrastructure. 2026.7 made purpose-specific automation triggers the default for everyone, so you describe what your home should do instead of which entity changes state. 2026.8 went further and removed the :8123 port from new installations, moved web server configuration out of YAML into the interface, and deleted the words advanced and expert from roughly 43 places. The capability surface is not shrinking; the vocabulary required to reach it is.
◆ Where it's heading
The pattern is consistent: take something that only worked if you already understood Home Assistant's internals, and re-express it in terms of the outcome the user wants. Triggers moved from entity-and-state to intent, the card picker moved from which card type to which thing in your home, and addressing moved from a memorized port to an ordinary web address. Each step ships with a migration that leaves existing installs untouched, which is how the project widens its audience without breaking the technical install base it already has. Integrations teaching the automation engine their own triggers is the piece with the most compounding left in it.
◆ Prediction
Expect the next releases to keep converting Labs experiments into defaults and to move the remaining YAML-only configuration surfaces into the interface, following the pattern the web server settings just set.

Windmill gives its AI agents a test harness, the piece that lets them into production flows
◆ Current state
Windmill is a developer platform for scripts, flows and internal apps, shipping weekly across three lanes. The AI lane is the busiest: sessions that build scripts and flows as reviewable drafts, a read-only plan mode that refuses writes until you approve, version history on session artifacts, and now evaluation for reusable agents. The runtime lane keeps absorbing data tooling — dbt projects run natively, BigQuery and Snowflake came out from behind the Enterprise licence. The workspace lane is consolidating deployment semantics around fork lineage.
◆ Where it's heading
The AI work has moved through a recognisable sequence: first let the assistant build things, then constrain what it may do without approval, then make its output reviewable and revertible, and now make agents measurable against a fixed set of cases. That is the arc of taking AI from a demo surface to something you are willing to put in a scheduled flow. In parallel, Windmill keeps pulling data-stack runtimes inside its own execution model rather than integrating with them, and keeps giving away runtimes that were previously licensed.
◆ Prediction
Evals are the obvious hook for regression gating, so expect them to be callable from a flow or CI rather than only from the agent card, and expect the eval run history to feed the same version-comparison surface the session artifacts already use.
