Currents vs Windmill: at a glance
What is Currents?
Currents moved into the IDE and repriced itself around self-serve in the same fortnight.
Currents publishes short labeled changelog entries, and the visible window runs from April to August. Two carry real weight: a VS Code and Cursor extension bringing CI runs, failure triage and Playwright traces into the editor, and a pricing restructure a week later adding a self-serve Business plan, cheaper rates, revised overage and yearly usage pooling. Around them sit integration work with Linear and Slack, and a @currents/playwright 2.0 release supporting Playwright 1.60 and newer.
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.

Currents

Currents moved into the IDE and repriced itself around self-serve in the same fortnight.
◆ Current state
Currents publishes short labeled changelog entries, and the visible window runs from April to August. Two carry real weight: a VS Code and Cursor extension bringing CI runs, failure triage and Playwright traces into the editor, and a pricing restructure a week later adding a self-serve Business plan, cheaper rates, revised overage and yearly usage pooling. Around them sit integration work with Linear and Slack, and a @currents/playwright 2.0 release supporting Playwright 1.60 and newer.
◆ Where it's heading
Currents is moving its surface toward where failures get fixed rather than where they get reported. The IDE extension, the Linear integration and the Slack notifications all describe the same handoff, and each one names agents alongside humans as the consumer. The pricing change points the same way commercially: a self-serve Business tier removes the sales conversation from the middle of the funnel, and that is precisely the tier an IDE extension is most likely to pull in.
◆ Prediction
Expect the agent-facing framing to become explicit, with the IDE extension and the API growing structured failure output a coding agent consumes directly rather than prose written for a human reader.

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.
