Web Design Thailand: Custom Bilingual Websites for Thai Businesses
A real, custom-built Thai/English website with a built-in AI concierge and local SEO. Designed by a Bangkok team, live in 2-4 days, and fully owned by you. No templates, no platform lock-in.
Most "cheap website" deals in Thailand are recycled templates that look like every other shop on the street. The expensive end quotes you tens of thousands of baht upfront with nothing promised in return. WebSiam sits in between: a genuinely custom, done-for-you website in both Thai and English, at a low monthly price you can plan around.
We build for how Thai customers actually buy. They search Google for your service, they message you on LINE, they pay with PromptPay, and they do all of it on a phone. Your site is shaped around that from day one. The English reads cleanly for expats and tourists. The Thai is written by people who actually speak it, never run through a translation engine.
What you get
Custom design, not a template
Every page is built around your brand, your services, and your customers. No off-the-shelf theme that ten other Bangkok businesses are already running. Your site looks like you, sounds like you, and sells because it matches how you actually win customers.
Real Thai and English, done right
Two proper languages, written by humans, with correct hreflang so Google shows the right version to each visitor. Tourists, expats, and medical-tourism patients get clean English; Thai customers get natural Thai. No clumsy Google Translate.
Nisa, your 24/7 AI concierge
A built-in trilingual chatbot (Thai, English, French) answers questions and captures leads day and night, including the late-night and weekend enquiries that usually slip through. It's LINE-ready, so it meets buyers on the app most Thais already live in.
Live in 2-4 days
Most WebSiam sites go live within two to four days. No waiting weeks for a quote and months for a launch. You send us your details, we build it, you review it, and you go live and start getting found.
You own everything
Your domain, your content, your site. No platform lock-in, no holding your business hostage. If you ever want to walk away, you take all of it with you, which is the opposite of how template builders keep you stuck.
Managed hosting plus local SEO
Secure hosting with SSL and automatic backups is handled for you, so no surprise renewal or downtime bills land on your desk. We set up local SEO so you show up when someone searches your service plus your city, from Bangkok to Phuket, Pattaya, and Chiang Mai.
Templates and freelancers vs a custom WebSiam site
The Thai market splits into two painful extremes. At the bottom, template shops sell ready-made sites that look identical to the competition and rank for nothing. At the top, agencies quote large one-time fees, a heavy bill for a small business with no promise of results. In the middle sit freelancers, and Pantip is full of stories of deposits taken and people who vanish before launch.
WebSiam is the middle path that should have existed all along: agency-grade custom work, a Bangkok team that actually does your edits, and a low monthly price with a one-time ฿999 Setup & Tracking fee that's free on annual plans. No five-figure upfront gamble, no disappearing freelancer, no cookie-cutter theme.
Template shops: cheap, generic, invisible on Google, and not truly yours
Big agencies: large upfront fee, slow, risky for a small business
Freelancers: deposit risk, ghosting, half-finished work, no support after launch
Built for how Thailand buys: LINE, PromptPay, mobile-first
Most Thais use LINE, and many shoppers chat with a business there before they ever open its website. If your enquiries die somewhere between a LINE message and a follow-up, qualified buyers just walk. Nisa, your AI concierge, catches those leads automatically and keeps the conversation going at 2am.
PromptPay is now a default way to pay across Thailand, and almost every Thai visitor arrives on a phone. So we design mobile-first and fast, with easy PromptPay QR on commerce sites, instead of heavy, slow homepages that visitors abandon and Google holds back under mobile-first indexing.
LINE-ready chat and lead capture, where your customers already are
PromptPay QR built in for shops and bookings
Mobile-first, fast-loading pages designed for Thai smartphone users
Plans for every kind of Thai business
Pick the plan that fits where your business is now, then move up as you grow. Launch (฿497/mo) is a sharp one-page site for solo owners and new businesses that need to get found on Google and LINE fast. Local Growth (฿997/mo, our most popular) gives you up to five pages, services, about, and contact, plus local SEO and five edits a month, ideal for an established SMB. Commerce & Booking (฿1,297/mo) adds a catalog or booking system with unlimited edits, made for shops, clinics, and restaurants.
Need a property-listing portal or a store with 10+ products? Our Tailored tier is quote-based for custom builds. And when you're ready to push harder, add SEO from ฿6,900/mo or Ads from ฿5,900/mo plus your ad budget, recurring marketing add-ons that sit on top of your site, not the price of the site itself.
Launch ฿497/mo: one-page site, get found on Google + LINE
Local Growth ฿997/mo (most popular): up to 5 pages, local SEO, 5 edits/mo
Commerce & Booking ฿1,297/mo: catalog or booking, unlimited edits
How much does a website cost in Thailand with WebSiam?
Plans start at ฿497/mo for a one-page Launch site, ฿997/mo for our most popular Local Growth plan (up to 5 pages), and ฿1,297/mo for Commerce & Booking. There's a one-time ฿999 Setup & Tracking fee, free on annual plans. Compared with agency quotes that run into tens of thousands of baht upfront, there's no big initial gamble.
Who owns the website and the domain?
You do, completely. Your domain, content, and site belong to you, with no platform lock-in. If you ever decide to leave, you take everything with you. That's the opposite of template builders that trap your business inside their system.
Do you build websites in both Thai and English?
Yes, bilingual Thai/English is what we do best. Both languages are written by people, not Google Translate, with proper hreflang so Google shows the right version to each visitor. It works well for businesses serving Thai customers alongside expats, tourists, and medical-tourism patients.
How fast can my website go live?
Most WebSiam sites are live within 2 to 4 days. You send us your details and content, we build the custom design, you review it, and we publish. No waiting weeks for a quote or months for a launch.
Can you handle edits for me after launch?
Yes. A Bangkok-based team handles your changes, so you never have to learn anything technical. Local Growth includes five edits a month and Commerce & Booking includes unlimited edits, with no slow, paid, per-change runaround.
Will my site rank on Google and work with LINE?
Yes. We set up local SEO so you get found when people search your service plus your city, whether that's Bangkok, Phuket, Pattaya, or Chiang Mai. Your site is LINE-ready, and Nisa, the built-in AI concierge, captures leads from chat around the clock.
