A repeatable, transparent framework that keeps projects on time and on budget.
We spend time understanding your goals, users, and constraints before writing a single line of code. This prevents expensive rework later.
Wireframes and high-fidelity Figma prototypes that you can interact with and sign off on before development begins.
Iterative development with weekly check-ins and a staging environment so you can review progress in real time throughout the build.
Zero-downtime deployment, post-launch monitoring, and an optional ongoing support retainer to keep your product running smoothly.
WebModuleX was founded in Sydney in 2019 by developers who were frustrated by agencies that over-promised and under-delivered. We are a tightly-knit team of engineers and designers who care deeply about code quality, performance, and honest communication.
We work with a small number of clients at a time to give each project the attention it deserves. No account managers, no outsourcing — the people you speak to are the people who build your product.
Fixed-price quotes with no surprise extras. You know exactly what you're getting and what it costs before work begins.
Every decision — from architecture to image formats — is made with load time and Core Web Vitals in mind from day one.
OWASP best practices, automated security audits, 99.9% uptime SLAs, and regular dependency updates as standard practice.
We use agile sprints and weekly updates so there are no surprises. If a deadline is at risk, you hear about it early — not the day before launch.
Real feedback from Australian businesses we've built digital products for.
“WebModuleX rebuilt our e-commerce platform in just 6 weeks. Our conversion rate went up 38% in the first month. The team was communicative throughout and delivered exactly what they promised — no surprises on the invoice.”
“We hired WebModuleX to build our SaaS analytics dashboard from scratch. They nailed the architecture on the first try. The codebase is clean, well-documented, and has scaled effortlessly from 500 to 12,000 users without a single incident.”
“Fantastic team to work with — genuinely honest about timelines and scope. Our PWA booking portal scored 98 on Lighthouse and our clients love how fast it feels. The 30-day post-launch support gave us real peace of mind.”
Project costs vary widely based on scope and complexity. A focused marketing website typically starts from $6,000 AUD, a custom web application from $18,000 AUD, and a full SaaS platform from $40,000 AUD. We provide a detailed fixed-price quote after our initial discovery call — there are no hourly billing surprises.
A marketing website is usually delivered in 4–6 weeks. A custom web app runs 8–16 weeks depending on features. We always provide a timeline breakdown in our proposal and use a staged milestone approach so you can review progress throughout — not just at the end.
Yes. While our studio is based in Sydney and most of our clients are Australian, we regularly work with businesses in New Zealand, the UK, and the US. We accommodate different time zones for calls and use async-first communication to keep projects moving efficiently.
All projects include 30 days of post-launch support at no extra charge. After that, we offer monthly maintenance retainers covering security patches, dependency updates, performance monitoring, and priority bug fixes. You are never left without support after we hand over the keys.
Absolutely. Upon final payment, full intellectual property ownership of all custom code, designs, and assets transfers to you. You receive the complete source code in a private Git repository, all Figma design files, and full access credentials to all services. No lock-in, ever.
