Wix, Webflow, Squarespace or a custom site: an honest comparison

Wix, Webflow and Squarespace promise a site live in a few days at a fraction of an agency's price, and for certain projects they keep that promise. The hard part is figuring out beforehand, with concrete criteria, whether your project is one of them: the comparison between site builders and a custom site is won by looking at costs over time and real limits, not at the polished demo. We'll walk you through it the way we do for clients who ask us, including the ones we end up advising to stick with the builder.

What builders do well

Let's start with the merits, which are real:

• Short timelines. A five-page brochure site can be online in a week, hosting included, without coordinating vendors.
• Low upfront cost. You pay a monthly subscription instead of a development project: to validate an idea or support a brand-new business, that's a genuine advantage.
• Maintenance included. Security updates, hosting and backups are handled by the platform: one less operational worry.
• Content autonomy. Changing a text or a photo doesn't require any technician.

Among the three, the differences in focus matter: Squarespace bets on simplicity and template aesthetics, Wix on the quantity of ready-made features, Webflow on fine-grained design control and a more serious CMS, at the price of a steeper learning curve.

The real costs over time

The honest comparison isn't between the builder's subscription and the agency's quote: it's between total costs over three to five years.

With a builder you pay every month, forever: the base plan, then the higher tier when you need more features, then third-party apps to fill the gaps (advanced forms, reviews, multilingual), often each with its own fee. The total stays manageable, but it grows as your needs grow, and it only stops if you shut the site down.

With a custom site the investment is concentrated at the start, and then you pay for hosting and maintenance, usually lower figures than the sum of subscriptions for the same features. The break-even point depends on the project: for a simple site it may never arrive, for a site with specific requirements it arrives sooner than you'd think, because on a builder you pay for those requirements in apps and workarounds.

Where builders hold you back

The real limits show up when the site stops being a showcase and becomes a working tool:

• Integrations with your systems. Connecting the site to your management software, your CRM or a booking system with your own logic: on builders, either there's an app that does exactly what you need, or you're stuck.
• Features outside the catalog. A quote calculator with your rules, a members' area with granular permissions, a non-standard order flow: these are normal requests for a business and impossible or fragile on these platforms.
• Advanced technical SEO. The basics are everywhere, but for fine-grained control (specific structured data, precise handling of complex redirects, under-the-hood performance optimizations) you hit the platform's ceiling.
• Serious multilingual support. Managing multiple languages with clean URLs and market-specific content remains a recurring weak spot, solved with add-on apps with mixed results.
• Lock-in. This is the most underestimated limit: you can usually export your content, but not the site. Design, features and configurations stay on the platform; if one day you want to leave, the site gets rebuilt from scratch.

When the builder is the right answer

We'll say it straight: if your project is a brochure site with a few pages, content you update yourself, a minimal starting budget and no integrations on the horizon, the builder is a sensible choice. It also works for validating a new business: better six months on Squarespace than six months waiting for the perfect site. The important thing is to go in knowing where the exit is: a domain you own and content written so you can take it with you.

When custom is worth it

A custom site pays off when at least one of these conditions is true: the site needs to integrate with systems you already use; you need features the app catalog doesn't cover; organic traffic is a revenue source and you want full control of the technical side; you operate across multiple languages and markets; you expect the site to grow in complexity over the next few years. In these cases the builder doesn't save you money: it pushes the costs further down the road and adds them to the cost of the rebuild, because sooner or later the rebuild comes.

A practical signal we often hear in first calls: if you notice you're adapting your work process to the platform's limits, instead of the other way around, the moment to make the jump has already passed.

Not sure which case you fall into?

We build custom websites and eCommerce, but the first thing we do in a call is figure out whether you need one: we advise a portion of the people who contact us to stay on the builder a while longer, and we put it in writing. If you're undecided between Wix, Webflow, Squarespace and a custom project, book a free call: we'll look at requirements, integrations and budget together, and tell you what we'd do in your place.
