What is Source by Webflow?
Source is a new Webflow platform, separate from the Webflow you use today. According to the company, it is a shared workspace where marketers, designers, developers and AI agents work on the same site. Each of them gets an interface built for their part of the job.
The idea behind it is that a website stops being a project you launch and freeze, and becomes something the team and its agents improve all the time: publishing campaigns, testing variants, tuning content for AI search engines and adapting the site to new markets.
Our take: this is the biggest change to Webflow since we started working with the platform. Until now, Webflow was a tool for building sites. With Source, Webflow wants to be the place where the marketing team runs its website every day. It is a different product, for a different moment of the work.
Why did Webflow create Source?
Because it changed how Webflow handles code. Until now, when you designed in Webflow you were not editing the site itself: you were editing an internal representation that Webflow then translated into the code the browser sees. Webflow itself acknowledged that this translation was a limit.
The arrival of AI agents, which read and write code fluently, gave them a way out. In Source, the code is the original, and both the visual editor and the agents work directly on it. According to Webflow, more than 30% of its enterprise customers were already using agents on their sites before the announcement.
Our take: it is an honest and necessary decision. Today anyone can generate a site from a prompt, so building fast no longer sets anyone apart. The hard part comes after: keeping the brand consistent, letting the team work without breaking anything and making the site better month after month. That is where Webflow is placing its bet, and it is the same ground we work on.
How does Source work?
We have not tried it yet: once we get access, we will add our hands-on experience to this section. For now, this is what Webflow has shared.
Code and visual editor on the same foundation. Agents work directly on the code that gets published, which lets them make bigger changes. When precision matters, the visual editor writes to that same code.
Views: an interface for each role. Each person works in a space built for their function: visual building, CMS, review, brand, agents, audit. Webflow ships default Views and lets you create custom ones, like a metrics dashboard or a content approval flow.
Agents that propose without being asked. According to Webflow, agents monitor site performance and leave ready-to-review proposals in an inbox for someone on the team to approve. For example, an improvement to show up in AI search engines, or a conversion test. You can also create agents for specific tasks, like checking that every new page follows the brand voice.
Comments that turn into tasks. You leave a comment on the design, for example “change this button to the new brand colors”, and an agent picks it up, prepares the change and leaves it for review.
Brand and permissions built in. The brand system (components, styles, voice and tone) is loaded into Source so that everything a person or an agent publishes follows it. There are role-based permissions, approvals and a log of which person or agent changed what. Each team decides how much autonomy its agents get.
It connects to what you already have. Source can connect to existing code, CMS, hosting and marketing tools, including sites built in Webflow.
Our take: of everything announced, the brand piece interests us most. If agents are going to publish changes on your site, quality depends on how well your brand system is defined. A PDF brand book is not enough: an agent needs components, rules and tone documented in a way it can apply. It is the work we already do with our clients, and with Source it becomes a condition for AI to work well.
What happens to your current Webflow site?
Nothing, for now. Webflow says the current platform stays and will keep getting improvements, including agent features. Moving to Source will be optional, and Webflow promises to support the migration once the product is ready.
Our take: if you are about to start a new site, do not wait for Source. There is no launch date, and a site built well in Webflow today, with an organized CMS and a clear component system, is exactly what will get the most out of Source when it arrives.
How much does it cost and when does it launch?
As of October 26, 2026, Webflow has not announced a price or a general launch date. Webflow already charges for some AI features with credits, so Source may include a usage-based component, but nothing is confirmed.
Our take: price will define who Source is for. Based on how Webflow presented it, with a focus on marketing teams and governance, it is aimed first at mid-size and large companies. For a small team, Webflow’s current platform will probably remain the best option for a good while. We will update this view once there is pricing.
What could change for B2B companies?
Our take: we see three concrete changes for B2B companies.
- The marketing team gains autonomy. Today many companies depend on a developer or their agency for any change to the site. Source promises that each person can do their part within clear rules.
- The site becomes a channel that is optimized all the time. With agents that spot opportunities and propose changes, the site stops being a project that gets rebuilt every three years.
- Brand becomes infrastructure. If people and agents publish on the same site, the brand has to be defined as a system. Companies that already have that solved will get much more out of Source.
What we still do not know
We would rather be clear about what is missing.
- Price and billing model. If it depends on usage, cost may be hard to predict.
- Product maturity. A research preview is an early version, and features may change.
- Real-world experience with agents. Webflow promises control and approvals, but we need to see how it works on real sites, with real teams.
- The migration path. Webflow promised it, but has not explained how it will work yet.
