What is v0 by Vercel?

v0 now generates AI-ready apps out of the box via Vercel AI Gateway — no API keys required.

v0 ships on roughly a weekly cadence, with each release adding model options, integration improvements, and UX refinements. The structurally significant move this cycle is zero-config Vercel AI Gateway authentication for every app v0 generates: generated apps now have built-in access to text, embeddings, images, video, speech, and transcription without the user providing API keys. Alongside this, direct Figma inspection replaced the older import-and-screenshot step, and the Shopify integration reached general availability. v0 is expanding from UI generator to full-stack AI app builder.

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.

v0 now generates AI-ready apps out of the box via Vercel AI Gateway — no API keys required.

◆ Current state

v0 ships on roughly a weekly cadence, with each release adding model options, integration improvements, and UX refinements. The structurally significant move this cycle is zero-config Vercel AI Gateway authentication for every app v0 generates: generated apps now have built-in access to text, embeddings, images, video, speech, and transcription without the user providing API keys. Alongside this, direct Figma inspection replaced the older import-and-screenshot step, and the Shopify integration reached general availability. v0 is expanding from UI generator to full-stack AI app builder.

◆ Where it's heading

The zero-config AI Gateway move is the clearest signal of v0's direction: Vercel is using v0 as the generation engine and AI Gateway as the infrastructure lock-in. Every AI-capable app built with v0 becomes a Vercel AI Gateway customer by default, creating a compounding platform advantage. The weekly cadence of model additions (Sol, Opus 5, Opus 4.8) shows v0 treating the model layer as interchangeable — the differentiation is in the generation quality, the integrations, and the deployment rails.

◆ Prediction

More production-grade integrations (Stripe, auth providers, databases) will follow the Shopify pattern of connecting live data to generated storefronts. Zero-config AI Gateway will likely expand to other Vercel infrastructure services, reinforcing the generated-apps-run-on-Vercel lock.

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.
