React website migration
React is built for apps. Your website just needs to be found.
Many business sites were built with React because a developer knew it, not because the site needed it. The result is pages drawn by code in the browser, which many search engines and AI assistants never see, and a pile of code that needs a developer for every change. I turn your site into plain, fast Redline pages with the same look and words, and nothing left to keep updated. Enter your address to see what your move would involve.
Typical level
Move + some custom work, including sites where people sign in. Big sites are a redesign and move.
Typical price
$2,800–4,000 for most React sites, $4,000–6,000 for big ones. Hosting and care is $150 a month.
Time
Usually 2–3 weeks. Your current site stays live until the new one is ready.
After the move
Edit your pages yourself in a simple editor, no developer needed, or let me: an hour of edits a month is included.
Why React websites are hard to find and costly to keep
A typical React site, built with Create React App or Vite, sends every visitor the same nearly empty page plus a bundle of JavaScript. The browser runs the bundle, which draws the page. That design makes sense for apps people sign in to and use all day. For a business website it costs you:
- Search engines and AI assistants miss your words. The tools behind ChatGPT, Claude and Perplexity mostly don't run JavaScript, and Google runs it late and not always. Every page also tends to share one title and description. When I built the same site six ways, the React version showed these tools one generic title and none of the content, on every page.
- Much more code. In that same test, the React build sent 293KB to the browser against 27–28KB for plain HTML: about ten times as much for the same three pages. Visitors download and run it all before they see anything, which hurts most on phones.
- Constant upkeep. A React site depends on dozens or hundreds of outside packages that need updates and security fixes. In another test, one landing page built with nine common packages pulled in 81 installed packages and 18MB of tooling, and shipped about 11 times the code of the same page in plain HTML.
- Every edit needs a developer. Changing a sentence means editing code, rebuilding and redeploying.
The free check above shows whether your pages are drawn by code. On Redline every page is plain HTML, sent complete, with nothing to rebuild or patch.
What moves over
Comes over
- Every page, with your words and images.
- Your design: same layout, colors and fonts, as plain HTML and CSS.
- Contact and sign-up forms, set up again in Redline.
- Your domain, and every page address you have now, including the ones your React router handles.
- Logins and free members-only pages: Redline supports sign-in and different access levels.
Needs a closer look
- Pages behind a login, and who is allowed to see each one.
- Interactive tools such as calculators, configurators or dashboards.
- Data the site reads from its own server or outside services.
- Payments, paid memberships and online stores, which aren't covered yet.
Small interactive pieces usually come over as plain JavaScript. For sites with logins, I work with whoever built your site to list every page behind the login and who can see it. Each is tested before we switch over.
How the move works
- Check your siteEnter your address above. You'll see the level, and I'll reply with a fixed price.
- I rebuild itI work from your live site. If you have the code, access to the repository helps with tools and hidden pages.
- You review itYou see the new site before anything changes, and I test that every old address still works.
- We switch overI point your domain at the new site. Your React code stays yours, untouched.
If you ever leave, here's what you take with you
Your website
As standard HTML, CSS and JavaScript files that any web host can run.
Your data
If your site keeps records such as members, bookings or form entries, you get a complete copy in a format other tools can read.
Your code
Anything built just for your business is yours. I don't own it and I won't keep it.
Your domain
It was always yours, and it goes wherever you go.
The Redline engine stays with me. Everything else goes with you. Your files, data and code are always handed over free. If you'd like help setting them up somewhere else, that's billed at my normal rate.
Questions about moving from React
Is React bad for SEO?
Not by itself, but a typical React website draws its pages in the browser, so the page search engines first receive is almost empty. Google can run the code later, though not always, and AI assistants mostly don't run it at all. Sites that send complete HTML for every page avoid the problem.
Can I convert my React site to plain HTML?
Yes. That's what this move is: every page becomes plain HTML and CSS with the same words and look, and small interactive parts become plain JavaScript. It loads faster, search engines read it easily, and there are no packages to keep updating.
How much bigger is a React site than plain HTML?
In my test of the same three-page site built six ways, the React build sent 293KB to the browser, about ten times the 27–28KB of the plain HTML builds, and its pages showed search crawlers no content. Plain pages are smaller, faster and readable by everything.
How much does it cost to move a React website?
Most React sites are $2,800–4,000 and take 2–3 weeks. Big sites, or ones with several tools to rebuild, are $4,000–6,000. Hosting and care is $150 a month, or $1,500 a year, with an hour of edits a month included. The free check on this page shows your site's level.
Can my site keep its logins?
Yes. Redline supports sign-in and different access levels. Because pages behind a login can't be seen from outside, I work with whoever built your site to map every one and who should see it, then test each before we switch over. Paid memberships, where people pay for access, aren't covered yet.
Will my links still work? React used its own routes.
Yes. Every address your site answers to today, including the ones its router draws in the browser, keeps working after the move. I test each one before we switch over.
Who's behind this
I'm Brad Simon, and Coder B Dev is my one-person studio. I've been writing software for more than 30 years: enterprise systems, web applications and SaaS platforms, for companies from startups to large enterprises. Redline is the platform I built so small business sites can get that same engineering without the upkeep. I take on a small number of sites at a time, so each one gets my full attention.
I'd rather you stay because you want to. I've seen too many business owners stuck with a platform because leaving meant losing their site. I don't work that way. Your words, images and data are yours, and so is any code written for your business: I don't claim any rights to it. If you ever decide to move on, I'll hand you your site as standard files, a full copy of your data and all of your own code, with no runaround. The only thing I keep is the Redline engine itself.
