Webflow custom code and integrations

Filters, calculators, gated content and connections to your CRM, built with the lightest tool that does the job: Webflow first, then Finsweet Attributes, then a small documented script where those stop.

Who this is for four common starting points

Most custom work starts from one of these.

Need the whole site built too?

See Webflow development
  1. 01

    Webflow almost does it

    You need filtering, a calculator or gated content, and the Designer has no setting for it.

  2. 02

    Your tools don't talk

    Form leads get copied into the CRM by hand, every week.

  3. 03

    A Webflow feature went away

    Webflow retired Logic in June 2025 and User Accounts in January 2026, and something has to replace them.

  4. 04

    Plugins slow the site down

    Heavy third-party widgets do a job a few lines of code could do.

Not a fit

If you need a full web app with user accounts and its own database, a product engineering team will serve you better.

Add to the same project one plan, one person

My other services, quoted together with the feature, so nothing gets lost between studios. Switch one on to see it join the plan.

How custom work runs in four steps

The same four steps every time, each ending with something you can check before the next one starts.

What shapes the timeline and the quote

Every quote is written for the project, starting from my published prices. These four things move it most.

Most single features take 1 to 2 weeks from signed quote to launch.

Custom code and integrations questions before you start

Have a question this list misses? Book a call and ask me. You talk to me, not a salesperson.

Will custom code slow my site down?

It shouldn't, and I check that it doesn't. Scripts are small, load after the page and run only where they're needed. I run PageSpeed before and after, so you can see the difference.

Can my team edit the site without breaking the code?

Yes. Scripts hook onto their own data attributes, not the classes your team styles with, so editing text, images and CMS items won't touch them.

Why doesn't my script run in the Designer?

Webflow doesn't run custom scripts inside the Designer. They run in preview and on the published site, so that's where I test them. Each code embed also has a 50,000-character limit, which is why longer scripts are hosted and loaded from a file.

Can you fix custom code someone else wrote?

Yes. I read it first, tell you what it does and what is risky, and quote to fix or replace it.
