Vibe Coding is a next-generation development approach where AI transforms natural language descriptions into production-ready code. Combined with Agentic AI - autonomous AI agents that execute multi-step workflows independently - it enables AI-Native software to be delivered 5-10x faster than traditional development methods.

Will I own the source code?

Yes. 100%. Full source code, database access, and infrastructure credentials. No lock-in, no dependency on FastDX.

How fast can you deliver?

Simple tools: 3-7 days. Business systems: 1-3 weeks. Complex platforms: 3-8 weeks.

Do I need technical knowledge?

No. Describe your business needs. We handle all technical decisions, development, and deployment.

What happens after delivery?

You own everything. Optional maintenance packages available for ongoing support.

Can you replace my existing SaaS tools?

In most cases, yes. We analyze your tools, consolidate what we can, and build a unified system.

How do you handle data security and compliance?

All projects follow OWASP security standards. We implement role-based access control, encrypted data at rest and in transit, and secure API authentication. For regulated industries, we support GDPR, HIPAA, and SOC 2 compliance requirements. Your data stays on your infrastructure.

How does your pricing compare to traditional agencies?

80% lower on average. A $50,000 agency project typically costs $5,000-$15,000 with FastDX. AI-powered development eliminates the largest cost drivers: manual coding, lengthy QA cycles, and project management overhead. You pay for results, not hours.

Why choose a Vietnam-based development team?

Vietnam has one of the fastest-growing tech workforces in Southeast Asia with 500,000+ IT professionals. FastDX combines this talent pool with AI-powered methods: you get enterprise-quality software at a fraction of US or EU agency costs, with timezone overlap for Asia-Pacific markets and English-language project management.

What tech stack do you use?

Primarily Next.js, React, Node.js, Supabase, PostgreSQL on Vercel or your preferred cloud.

What cloud platforms do you support?

For standard web applications, we deploy on Vercel with Supabase. For complex enterprise applications requiring higher security or compliance, we work with AWS, Google Cloud Platform, and Microsoft Azure. We choose the platform that best fits your requirements for performance, compliance, and budget.

Do you work with overseas clients?

Yes. Vietnam, US, Singapore, Japan, Korea and globally. Communication in English, Vietnamese and other languages depending on demand.

Build AI-powered software, agents, and intelligent systems for your business

FastDX helps individuals, teams, and organizations build AI-native software, autonomous AI agents, and intelligent workflow systems tailored to their operations. By applying modern AI-driven development approaches such as Agentic AI and Vibe Coding, we deliver solutions 5-10x faster while reducing development costs by up to 80%.

The software your business uses wasn't built for your business.

The SaaS Trap

You're paying $500-5,000+/month for tools that don't quite fit. When you stop paying, you lose everything, including your data.

70% of Features You'll Never Use

Generic software forces you to change your workflow. You adapt to the tool instead of the tool adapting to you.

Data Everywhere, Insights Nowhere

5-15 different tools, 5-15 different databases. No single source of truth. Reporting becomes manual guesswork.

Custom Development? Too Expensive.

Traditional software development costs $20,000-200,000+ and takes 6-18 months. Most SMEs can't even start.

70% of DX Projects Fail

Not because the technology is wrong. Because the approach is wrong. Big bang transformations don't work for most businesses.

When You Scale, Costs Multiply

SaaS pricing grows with your team, but not in your favour. More seats, higher tiers, premium add-ons. A $500/month tool becomes $5,000 before you notice. Custom software costs the same at 1,000 users as at 10.

Your software. Your rules. Built in days.

FastDX designs and builds AI-Native software, autonomous AI agents, and intelligent workflow systems using Agentic AI and Vibe Coding - 5-10x faster and up to 80% cheaper than traditional development.

If you can describe it, FastDX can build it.

What Our Clients Say

What clients say about working with FastDX and the impact we deliver.

We had 8 different tools that still couldn't share data with each other. FastDX built us one system that does everything. The subscriptions we dropped paid for the build within the first month.

David Miller

Operations Director

I expected a 3-month project. It took 10 days. Our sales team finally stopped asking where deals are in the pipeline and started actually closing them.

Sarah Kim

CEO & Co-founder

Two people used to spend their whole day routing orders manually. The AI handles it now. Those two are focused on building customer relationships instead, much better use of their time.

Michael Tran

General Manager

I've worked with teams that move fast and leave a mess. FastDX moved fast and left clean code. Proper architecture, clear structure: that's genuinely rare.

Jessica Williams

Product Owner

Year one: $63,000 saved just from cutting SaaS subscriptions. And we own the system outright. No monthly fees, no vendor dependency, ever.

Lisa Nguyen

Finance Director

Our digital transformation stalled for years before we met FastDX. They delivered a custom enterprise system in 5 weeks that our previous vendor couldn't build in 6 months.
