About Delix4

Small team. Direct communication. High-quality engineering.

Delix4 is a software development company based in Colombo, Sri Lanka, working with clients worldwide. We design and build web applications, mobile apps and AI-powered products for startups and growing businesses.

Being a focused team is a deliberate choice. It means you work directly with the people writing your code, decisions happen quickly, and every project gets senior attention from start to finish.

More about us

Direct communication

You talk to the engineers building your product — no account managers or layers in between.

High-quality engineering

Typed code, automated checks, security hardening and documentation are standard on every project.

Honest scoping

Clear estimates, realistic timelines and no inflated promises. If something is not a good fit, we say so.

Product thinking

We care about business outcomes, not just shipping features — and will challenge ideas that do not serve your users.

Why Delix4

Built on transparency

No inflated numbers or borrowed logos. Here is exactly where we stand.

FAQ

Questions clients often ask

How long does a typical project take?

It depends on scope. Business websites typically take 2–4 weeks and web applications 6–12 weeks. Mobile and AI projects are scoped after a discovery call. You get a detailed timeline before any work begins.

How much does a project cost?

Every project is quoted individually based on scope, features and timeline. Tell us about your project and we will send a clear, itemised estimate — there is no cost for the initial consultation.

Do you offer post-launch support?

Yes. Every project includes 30 days of free support after launch. After that we offer flexible maintenance plans to keep your product secure and up to date.

How do payments work?

We typically work with a 50% deposit to start, with the remaining balance due on delivery and your final approval. Larger projects can be split into milestone payments.

Do I own the source code?

Yes. Once the project is paid for, you own the full source code, designs and documentation.

Do you work with international clients?

Yes. We work remotely with clients in any time zone and communicate through email, WhatsApp, video calls and shared project boards.

Can you help with hosting and domains?

Yes. We handle domain setup, secure hosting, SSL and deployment so you do not have to worry about the technical details.
