Top 10 Web Development Companies in Vietnam (2026)

The top web development companies in Vietnam in 2026 include MONA, TMA Solutions, NashTech, KMS Technology, Savvycom, and Saigon Technology, ranging from 4,000-engineer outsourcing veterans to 100-person product studios. This guide compares all ten on team size, certifications, and specialties, so you can shortlist the right partner for your project and budget.

Vietnam has become one of Asia's strongest destinations for web development: a deep engineering talent pool, English-language delivery at established firms, and rates typically 50–70% below the US, Australia, or Western Europe. The hard part isn't deciding on Vietnam. It's telling hundreds of near-identical vendor websites apart. That's what this list is for.

How We Built This List (and a Disclosure)

Full transparency first: this article is published by MONA, and MONA is ranked #1. We're not pretending to be a neutral directory. You deserve to know who's writing. What we can promise is that every company on this list is real, established, and worth your consideration, and that every fact about them is drawn from a verifiable public source: the company's own website, Clutch.co, DesignRush, or LinkedIn. Where sources conflicted (headcounts often do), we used the more conservative figure. We claim no certification for any company we couldn't verify.

Selection criteria:

• Real web development capability. Web and web application work is a core service, not a footnote.
• Verifiable scale and longevity. Published founding year and/or headcount from a primary source.
• Independent credibility signals. Clutch/DesignRush reviews, ISO or CMMI certifications, or publicly named clients.
• Vietnam-based delivery. Engineering genuinely happens in Vietnam, even where the corporate HQ is abroad (noted where relevant).

Directories like Clutch and DesignRush are useful starting points, and we cite them throughout. But a listicle written by a practitioner can tell you things a directory can't, like which firm fits which kind of buyer. That's the lens for the profiles below.

1. MONA — Web Design, Development, and Hosting Under One Roof

HQ: Ho Chi Minh City · Founded: 2016 · Team: 200+ staff · Projects delivered: 14,000+

MONA started as a web design agency in 2016 and grew into a technology group spanning web, custom software, and its own cloud hosting infrastructure. That origin matters: web isn't a side service bolted onto an outsourcing shop. It's the foundation the company was built on. With 200+ staff across engineering and design and 14,000+ projects delivered across ecommerce, F&B, real estate, healthcare, and manufacturing, MONA covers the full journey, UI/UX design, WordPress development, ecommerce development, and custom web applications, then hosts and maintains what it builds. English-speaking project managers run delivery from GMT+7, overlapping European mornings and US evenings. Yes, this is our list and we put ourselves first. The disclosure above explains how to weigh that. The checklist at the end of this article is how we'd tell you to verify us, too.

Best for: businesses that want design, development, hosting, and maintenance from one accountable partner at Vietnamese rates.

2. TMA Solutions — The Veteran at Enterprise Scale

HQ: Ho Chi Minh City · Founded: 1997 · Team: ~4,000 engineers

Founded in 1997, TMA Solutions is the oldest company on this list and one of Vietnam's largest independent software outsourcers, reporting around 4,000 engineers and offices in Canada, the US, Australia, Singapore, Japan, and Germany. Its heritage is telecom. Publicly named clients include Avaya, Ribbon Communications, and NTT group companies, and it carries the process credentials to match: CMMI Level 5, ISO 9001, ISO 27001, and TL 9000. Today its services span web and mobile development, QA, AI, cloud, and IoT. TMA is built for large, long-running engagements; smaller web projects may find its scale more than they need.

Best for: enterprises that need proven capacity for hundreds of engineers and strict process certification.

3. NashTech — Enterprise Digital Engineering, UK-Led

3. NashTech — Enterprise Digital Engineering, UK-Led (AI-generated illustration)

HQ: London · In Vietnam since: 2000 · Team: 2,000+ engineering experts

NashTech is the technology arm of the Nash Squared family (acquired by investment firm PAG in late 2024), with group headquarters in London and its engineering heart in Vietnam's Ho Chi Minh City, Hanoi, and Da Nang since 2000. It reports 2,000+ engineers and was among the first in Vietnam certified CMMI Level 5 under v2.0, alongside ISO 27001 and ISO 9001. Clutch lists it at 4.7/5 with a $75,000 minimum engagement and $50–99/hour rates, firmly the premium end of the Vietnamese market. Publicly named clients include Evri, Dulux Group, The Open University, and Trinity College London.

Best for: enterprises that want Western account management with Vietnam-based delivery, and budgets to match.

4. KMS Technology — Product Engineering With a Track Record of Spin-Offs

HQ: Atlanta, USA · Founded: 2009 · Team: 1,000+ across 10 locations

KMS Technology is US-headquartered in Atlanta with major delivery centers in Ho Chi Minh City and Da Nang, a structure worth understanding if you're specifically shopping "companies in Vietnam." Its strongest proof of engineering quality is unusual: KMS built and spun off successful software products of its own, including Katalon, QASymphony, and Kobiton. That product DNA shows in its services, custom software, web and mobile development, testing, modernization, and GenAI. It holds ISO 27001, rates 4.8/5 on Clutch, and has been named among Vietnam's Top 10 ICT companies multiple years running.

Best for: funded startups and product companies that want US-style product engineering at Vietnam delivery cost.

5. CMC Global — Scale-Backed Delivery From Vietnam's #2 Tech Corporation

HQ: Hanoi · Founded: 2017 (parent CMC Corporation, 1993) · Team: 3,000+ engineers

CMC Global is the international delivery arm of CMC Corporation, one of Vietnam's largest technology corporations. Though the subsidiary itself launched in 2017, it scaled fast: 3,000+ certified engineers across Hanoi, Da Nang, and HCMC, plus offices in Tokyo, Osaka, Singapore, Kuala Lumpur, Seoul, and the US. Its certification stack is enterprise-grade: CMMI Level 5, ISO 27001, ISO 9001, ISO 20000, and PCI-DSS, and its services run from custom software and web platforms to cloud, data, and AI. Publicly named clients include Envato, RSupport, and SB Technology.

Best for: corporations that want corporate-group financial stability behind a large offshore team, especially for Japanese and APAC markets.

6. Savvycom — AI-Driven Development for Regulated Industries

HQ: Hanoi · Founded: 2009 · Team: 700+ tech professionals

Savvycom has grown from a Hanoi startup into one of northern Vietnam's best-known software firms, reporting over 700 professionals and offices from Seoul to Sydney. It holds one of the stronger Clutch profiles in the country (4.9/5 across 23 reviews) and self-reports 500+ projects delivered to clients in 30+ countries. Its current positioning leans hard into AI-driven development (GenAI now sits alongside custom software as a headline service), with sector depth in banking and finance, healthcare, and education. Publicly named clients include JIO Health and JK Moving.

Best for: companies in regulated sectors (finance, health, education) that want an AI-forward development partner.

7. Saigon Technology — ISO-Certified Offshore Custom Software

HQ: Ho Chi Minh City · Founded: 2012 · Team: 400+ engineers

Saigon Technology (officially STS Software Technology JSC) has built a reputation as a disciplined offshore custom-software partner, with 400+ engineers in Ho Chi Minh City and Da Nang and front offices in the US, Australia, Singapore, and Switzerland. It's ISO 9001 and ISO 27001 certified, rates 4.8/5 on Clutch and 5.0/5 across 72 DesignRush reviews, and publicly names clients including Standard Chartered Bank and Abbott. Services cover custom software, web and mobile development, AI, DevOps, and offshore development centers, with sector strength in fintech, healthcare, and ecommerce.

Best for: mid-market companies that want a certified, review-backed offshore partner without enterprise-tier minimums.

8. Orient Software — Web-Heavy Service Mix From HCMC

8. Orient Software — Web-Heavy Service Mix From HCMC (AI-generated illustration)

HQ: Ho Chi Minh City · Founded: 2005 · Team: 350+ tech staff

Operating since 2005, Orient Software is one of HCMC's longer-standing development firms, with 350+ technical staff and ISO 9001 and ISO 27001 certifications. What earns it a place on a web development list specifically: its Clutch profile shows web development as the single largest slice of its service mix (around 40%), ahead of mobile and custom software, which is rare among Vietnamese outsourcers, most of whom treat web as an afterthought. It carries a 5.0/5 Clutch rating and a 4.9/5 Google rating across 130+ reviews, with additional strengths in QA, UX/UI, and staff augmentation.

Best for: mid-size businesses whose project is genuinely web-first rather than general software outsourcing.

9. Rikkeisoft — Vietnam's Japan-Market Specialist

HQ: Hanoi · Founded: 2012 · Team: 1,000+ staff

Founded in 2012 by six developers, Rikkeisoft has become one of Vietnam's fastest-scaled homegrown IT companies, now with roughly 1,000+ staff across about nine locations including Japan and Texas. Its center of gravity is the Japanese market, a useful signal in itself, since Japanese enterprise clients are famously demanding on documentation and process discipline. Rikkeisoft is CMMI Level 3, ISO 27001, and ISO 9001 certified, holds a 5.0/5 Clutch rating (from a small review base), and offers software development, web and mobile, QA, UX/UI, and BPO alongside its Rikkei Digital and Rikkei AI ecosystem units.

Best for: companies, especially those serving Japanese or process-heavy markets, that value documentation rigor.

10. Designveloper — The Boutique Web-First Studio

HQ: Ho Chi Minh City · Founded: 2013 · Team: 100+ staff

Designveloper is the deliberate counterweight to the giants above: a single-office, 100+ person studio in Ho Chi Minh City focused on web application development, custom software, and UX/UI. Its best-known credential is product work: it built Lumin, the widely used web-based PDF editor, and its client list on its own site skews toward startups and education products like Walrus Education. Clutch rates it 4.9/5. You won't get CMMI certifications or a 500-engineer bench here, and that's the point: for a startup MVP or a focused web product, a boutique that ships is often the better fit.

Best for: startups and SMBs that want senior attention on a web product without enterprise overhead.

How to Choose a Web Development Company in Vietnam

Ten good companies is still nine more than you need. Here's how to narrow the field:

1. Match scale to scale. A 4,000-engineer firm and a 100-person studio are both excellent, just for different buyers. Enterprise compliance project? Look at TMA, NashTech, CMC Global. Startup web product? Designveloper-sized. Business website, ecommerce store, or web platform with design, build, and hosting in one contract? That's the profile MONA is built for.
2. Verify the team is in-house. The most common offshore failure mode is a vendor that resells your project to subcontractors. Ask what percentage of the people on your project are on the company's own payroll, and ask to meet your actual PM before signing.
3. Check what "web development" means to them. For many Vietnamese outsourcers, web is 10% of the business. If your project is a website or web application, favor firms where web is the core competency, and dig into their process on our guide to choosing a web design company in Vietnam.
4. Insist on IP ownership in writing. NDA before technical discussion, full assignment of code and designs on payment, repositories under your control. Every reputable firm on this list will agree; anyone who hesitates is telling you something.
5. Plan past launch. Websites and web apps need maintenance for years. Confirm warranty terms and whether the team that built your product will support it, or whether you'll be shopping for vendor #2 within twelve months.
