On September 2, 2026, at Webflow Conf 2026, Webflow previewed Source, a code-based environment where marketers and agents build together, according to its roundup of the conference announcements. Source connected a company's codebase and martech stack in one environment for agentic and visual development, and was in a limited research preview.

What changed

Campaigns generated landing pages, audience variants and ad creative from a brief and could push ads into channels such as Google Ads. It was in beta, with purchase planned for the month after the announcement.
Assets, an agentic way to produce and adapt on-brand creative, was built on technology from Vidoso, which Webflow acquired earlier in 2026. Its beta was planned for October.
MCP 2.1 added GSAP-powered Interactions, better CMS querying and Webflow Cloud deploy error logs for agents such as Claude Code, Codex or Cursor. It was due for all users later in September.
Releases let teams branch an entire site, including pages, CMS content, components, assets and locales, to stage big launches. It was due in beta later in 2026.
Webflow AEO added content agents that find topics where competitors get cited and draft content in the CMS, and Agent Instructions could be generated automatically.
Agent Presence showed where agents were working live on the site canvas.

What it means for people building with AI

A major visual site builder recast itself around agents working directly on code. For people building sites with Webflow, Source, MCP 2.1 and Agent Presence pointed to a workflow in which marketers and agents, including external agents such as Claude Code, Codex and Cursor, worked in the same environment.
