At the recent 2026 Webflow conference, the company made a number of product announcements, with the pinnacle being Source by Webflow, an agentic marketing platform built specifically for marketing teams and designed to take on the agentic Integrated Development Environments (IDEs) from Anthropic, OpenAI and others.
If you’ve used AI coding tools like Claude Code, Cursor, or OpenAI’s Codex, you know they are built primarily for engineers and highly technical people. But creative and technology agencies use them, as do some people in Marketing because they enable the automation of marketing activities using AI. But if you are an agency and need to hand off that code to a marketing team, it’s a challenge.
Webflow’s pitch is that it has a new way to leverage agentic AI in marketing, making it easier for agencies to provide new websites and campaigns and marketing teams to manage their web experiences with the help of AI.
It’s called Source by Webflow and it is a governed workspace for Marketing and its AI agents to work on web experiences, including websites and campaigns. The desktop application can connect to any existing codebase, not just from Webflow. It is composable by default, which means you can connect a company’s martech stack and provide a unified environment for Marketing teams. Marketers get a visual working experience, while agents get direct access to the code. And it all works with brand standards, permissions, and business rules.
This is an agentic workspace, so there are a lot of AI capabilities in the platform, but Marketers don’t have to always write prompts to get work done. Sometimes, it starts with a prompt but then moves on to a visual interface for fine-tuning. One example Webflow Chief Product Officer (CPO) Ben Haefele points to is a Brand Agent testing web page header variations. The Marketer starts with a prompt, reviews the options the agent provides and then is able to tweak a selected option using visual controls.
Thehem, including agent-based updates and notifications. Agents continuously monitor site and campaign performance and surface opportunities for improvement. Or a marketer can ask the AI to review something (like campaign performance) and have the review show in a view
Haefele says that most marketing tools require teams to bend their processes and workflows to meet the tool and this is true. The
Giving agencies an AI tool playbook
Creative and technology agencies are in the cross-hairs these days as more companies bring their marketing activities in-house with the support of AI. To remain relevant and successful, agencies need an AI marketing playbook.
But as Haefele points out, agencies that use AI to build marketing websites and campaigns using an agentic IDE, need something better to send clients than a codebase that requires engineering effort on the part of the client.
Theject from scratch or connect to an existing codebase, onboard the client’s tech stack, customize the workspace and agents, and hand off the entire IDE to the client. There’s no engineering requirement, it’s all done through Source
It’s a very good way to collaborate as well, with both the agency team and the client working closely together in one unified environment. Webflow says agencies can create a This isn’t white labeling, Haefele explains, but the ability to leverage theing role
A few additional AI-driven updates
Thet there are also a few more interesting updates worth mentioning
Haefele says Webflow now offers Campaigns for high velocity demand generation teams. Marketing teams are struggling with organic traffic, he reckons, and as a result are shifting attention and budget to paid traffic. The Campaigns solution helps a marketer create briefs to share with agencies, as well as produce landing pages and collateral for ad platforms. This feature is available through therm
The other big news is a new digital asset management (DAM) solution, built from the Vidoso acquisition that happened earlier this year. Using DAM, marketers can remix existing assets, with AI deconstructing the elements of an asset, allowing marketers to make changes. For example, reusing an ad image but changing the text on the image. Other announcements included an update to the Webflow MCP and the ability to track agent-made changes in the site activity log.
My take
Webflow’s vision has always been to democratize web experience management for everyone and it has built a platform that has done that to some degree. Designing and building a website using Webflow does require some level of design and technical chops, unless you use Webflow’s AI tools, but this new platform is different.
The Source is an extension of Webflow’s original vision, but it used AI to build a marketing platform that helps marketing teams strategize, analyze, create, and manage experiences in one place. I had the opportunity to see it work and it is a solid platform for marketing teams that don’t want to move between marketing tools or spend their days in agentic IDEs that are not always the easiest to learn if you aren’t technically savvy (or have the time to learn). That’s not to say that there isn’t some amount of set up and configuration that has to happen to get started.
The Source is also a good platform for agencies that are building out their AI skills and need a tool that works well with clients. Agency teams can build out the agent instructions, configure agents and build custom ones, and create the exact workspaces marketing teams need. This platform has the ability to create even tighter collaborations that keep the agency/clinet relationship going, even when AI is driving more work in-house because the agency can be the configuration support that many marketing teams don’t have the time to build.
The other very interesting point is that thehat builds web experiences using another Content Management System (CMS) can use this platform. That’s important, because it means Webflow is trying to build something bigger than it’s own CMS and that takes the company in an entirely new direction
Thell likely be awhile before it hits general availability
