Custom Web Apps & Tools
Build the tool your business runs on.
Maybe you need an interactive calculator, an assessment tool, a member portal, or a custom plugin, something that does a job instead of sitting there. The hard part is finding a partner who can engineer it and make people want to use it. Here, you get both.

What we build
From an idea to a tool people actually use.
If it runs in a browser and has to work flawlessly for real users, we can build it, often on WordPress, so your team can own and maintain it after launch:
Data-driven web apps
Collect, calculate, and report on real data, from guided intake flows all the way to year-over-year reporting.
AI-powered tools
We build AI in where it genuinely helps, like turning a complex technical standard into guidance anyone can follow.
Interactive calculators
Carbon, pricing, ROI, or eligibility: we turn your most complex question into a clear, instant answer.
Assessment & audit tools
Self-assessments and scorecards guide your users to a personalized result, and turn that engagement into qualified leads for your team.
Job boards & career sites
Post roles, accept applications, and manage candidates from a branded board built around your recruitment workflow.
Member portals & dashboards
A secure space where members, clients, or staff log in, see their data, and get things done.
Custom WordPress plugins
New functionality for the site you already run, designed to fit cleanly and stay easy to update.
Whatever your field, there’s a tool your audience wishes you had. Recruiters win with job boards, salary guides, and candidate portals. Federations and NGOs with self-assessments, audit tools, and member platforms. Professional services with ROI calculators and client intake. Publishers with quizzes and product finders. Interactive tools like these convert several times better than static pages, and AI now makes them faster and more affordable to build.
Featured build
Our latest build.
For the Confederation of Danish Industry (DI), we built a greenhouse-gas accounting platform for employers’ federations. Each country’s edition carries its own emission factors and branding: the Philippines first with ECOP, then South Africa with SEIFSA and Kenya with EAGC, with Ghana and more to come.
The Carbon Calculator
- White-labelBranded per organization and country
- Scopes 1–3Ten emission categories
- Guided entryThe right factor, applied for you
- PDF and CSVA report for every year
Members should use it without training, finish in under a minute and get a score.
Every line of the brief becomes something on screen.
Our process
How we build it.
Discovery & scope
We map what the tool must do, for whom, and what success looks like, with a fixed scope and price wherever possible.
Design & UX
We design the flow and interface so the tool is genuinely easy to use, and write the content that guides users through it.
Build sprint
We build and test in focused iterations you can see and shape, on a solid, maintainable stack.
Launch & iterate
We ship it on managed cloud hosting, help people find and use it, and improve it from real usage. Aftercare included, for peace of mind.
Why Content Hacker
Most dev shops build features.
We build tools people finish.
A tool only matters if people use it. We’re a content, UX, and search team as much as an engineering one, so your tool ships with the words, flow, and polish that get users to complete it. And because national federations run their member tools on our builds, the engineering underneath is held to that standard. You get a tool that’s reliable and secure, on a stack your team can own.
One team writes it, designs it, makes it findable and builds it.

Frequently asked questions
Questions, answered.
How much does a custom tool cost?
It depends entirely on scope: a simple calculator is very different from a multi-tenant platform. We start with a paid discovery to define exactly what you need, then quote a fixed scope and price wherever possible.
How long does a custom tool take to build?
Simple calculators and assessments can ship in a few weeks; platforms take longer. Discovery gives you a clear timeline up front, and our sprint approach means you see working software early, not just at the end.
What do you build on?
WordPress for most builds, extended with custom development where needed, so your team can own and maintain the tool, with the option for us to handle it.
Can it be white-labeled or rolled out to multiple markets?
Yes. Our carbon accounting platform is branded per organization and customized for each country, all from one core platform. We can build yours the same way.
Can the tool be AI-powered?
Yes. We build AI in wherever it makes your tool simpler or faster for the user: plain-language guidance, smart scoring, automated reporting.
Do you maintain it after launch?
Yes, top-tier managed cloud hosting plus aftercare and care plans, so it keeps running smoothly.
