Most people searching web agency vs Wix are not choosing a first website. They already have one, it works, and something has started to hurt: a page that will not rank, a feature the editor cannot do, a load time that will not budge. Here is where the platform's hard edge actually is, where it is not, and how to tell which side of it you are on.
What Wix actually gets right
Wix solves a real problem, and for the case it targets it solves it better than a custom build ever could. Someone with no technical background can go from nothing to a live, responsive, HTTPS secured, backed up site in an afternoon. No server to patch, no dependency upgrade that breaks the build at 2am, no hosting invoice to reason about. Dismissing that is how an agency loses credibility in its first paragraph.
The commercial logic holds too. Paid plans sit in the low tens of dollars a month at the time of writing, more for the business and commerce tiers, and that single line covers hosting, CDN, certificates, backups and a support desk you can shout at. Assembling those pieces yourself costs more attention than most small businesses can spare.
The platform has also closed real gaps. You can edit title tags and meta descriptions per page, set canonical tags, edit robots.txt, generate a sitemap, add structured data and manage 301 redirects. Anyone still saying Wix has no SEO controls stopped looking years ago. The useful criticism is narrower: you control the fields the platform exposes, and nothing underneath them.
Where configuration ends and code begins
The real difference is not a feature list. It is the line between filling in fields and writing code. On Wix the platform decides what HTML, what JavaScript and what HTTP headers reach the browser. That is fine right up until the fix you need lives below that line.
The concrete cases look like this. URL structure is largely dictated: blog posts, product pages and dynamic pages sit under paths the platform defines, so the flat, intent led hierarchy you would want for a large content section is not yours to build. Response headers are not yours either, so cache policy and anything like a Content Security Policy are set by someone else. Server side logic runs in Velo, which is genuinely capable, but it is a platform runtime: that code does not lift out and run somewhere else.
Selling across borders is where this bites hardest. A multilingual Wix site follows the model the multilingual system supports, and hreflang is generated for you inside that model. If your market structure does not match it, per country URL patterns, one language served in several countries with pricing pages that differ and need to be indexed separately, there is no lower layer to drop into. Same story for a custom search index, a headless product feed, or a webhook driven sync with a client's ERP. None of these are hard problems. There is simply nowhere to put them.
Performance, and the honest version of it
Speed is the argument agencies make worst. The truthful version: a Wix page loads the platform's own runtime before it loads your content, and you cannot code split it, defer it or remove it. Add a handful of marketplace apps, each with its own script, and the cost compounds. Largest Contentful Paint is usually recoverable with lighter hero media. Interaction to Next Paint, the metric that punishes heavy JavaScript on mid range Android phones, is the one you cannot argue with, because the code causing it is not yours to touch.
The reverse is just as true and deserves saying just as plainly. A custom build is not automatically fast. We have seen React sites slower than any Wix page: a font stack loading four weights nobody uses, a client bundle close to a megabyte on a brochure site, images served at full resolution, a tag manager firing half a dozen scripts before first paint. Owning the stack only helps if somebody actually uses that ownership.
So the fair framing is not fast against slow. It is fixable against not fixable. On Wix, when field data says your mobile experience is losing people, your levers are fewer apps and lighter media. On a stack you own, every layer is on the table: rendering strategy, bundle size, image pipeline, cache headers, and what is allowed to run at all before first paint.
Portability: what leaving actually costs
This is the part people underestimate, and it is worth understanding before you commit rather than after. A Wix site is not a folder you can copy. There is no export that reproduces your pages somewhere else. Blog content and product catalogues can be extracted with effort, but layouts, design decisions and any Velo code are platform bound. Media sits on Wix's own asset domain, so every image reference has to be rehomed. Form submissions, contact lists and data collected through apps each have their own export path, and some have none at all.
Then there are the URLs. Because paths are partly platform defined, a rebuild almost always changes them, which means a redirect map and a stretch where rankings move around before they settle. All of it is doable. It is simply work, and it is work you pay for on the way out instead of on the way in.
Three habits make that exit cheap, and you should adopt them today whatever you decide. Register the domain with a registrar you control, not through the site platform. Keep original, full resolution copies of every image and every piece of copy outside the platform. Run analytics in a property you own rather than the built in dashboard alone, so your historical data survives the move.
When Wix is the right answer, and when not to hire us
Stay on Wix if the site is a credible storefront rather than an acquisition channel. A single location restaurant, a practitioner whose appointments come by word of mouth, a portfolio, a firm that wins work on referral and needs to look legitimate when someone checks: the platform does that job well, and a custom build there buys you nothing a visitor will ever notice.
Stay on Wix if nobody on your side will maintain anything. A custom site is an asset with an owner. If the honest answer is that nobody will touch it for two years, a managed platform is the safer home for it.
Stay on Wix while you are still testing. If the offer, the positioning or the market is unsettled, spend the money finding out what works, then rebuild once you know.
And do not hire us if you want people in a room. We work in writing only, so if your process needs a weekly video call, a kickoff workshop or somebody on site, we are the wrong shop. We are not an emergency desk either: we reply within 24 business hours, which is not the same thing as instant. If you want a large agency with account managers and round the clock phone cover, buy that, because we cannot pretend to be it. And if you want the same site rebuilt in code with nothing else changed, the honest answer is usually that the money belongs in content and in whatever is actually failing.
How two people in Dijon work with a client in Austin or Bangalore
We are two people. Robin Monteiro builds (full stack, Next.js and React), Florian Loppion handles the marketing side. One office, at 9 rue Jean-Jacques Rousseau in Dijon, France. No branch abroad, no account management layer, no junior nobody told you about. You are writing to whoever is doing the work.
Everything runs in writing, by email. No calls, no video, no scheduled slots, not even as an option. For an international client that removes the worst part of hiring across borders, which is the time zone. Nobody in California takes a 3am call to unblock a decision. You send a question at the end of your day and the answer is waiting when you start the next one, within 24 business hours.
The second effect matters more over time. Every decision, every trade off and every approval is written down and searchable. Eight months later, when a new developer asks why the checkout behaves the way it does, the reasoning is a search away instead of a memory nobody quite trusts.
What changes on your side: write the brief instead of talking it through, batch your feedback rather than sending it in drips, and be specific (URL, screenshot, what you expected to happen). Pricing is on request, there is no mandatory subscription, and at the end you own the code, the accounts and the domain name.
