You see everything in the client panel

Every client gets an account in the VulCode panel. The project, the schedule, approvals, conversations, payments and tools are in one place instead of scattered across an inbox.

The VulCode client panel overview

The whole collaboration on one screen

After signing in you see your wallet balance, the invoices to pay, active projects and open tickets. Every project shows its stage and how much you have paid. Recent activity gathers the notifications about projects, payments and tickets. One screen answers what is going on and what waits for you.

A project card with its finances, links and details

Every project has its own card

The project value, the part already paid and the payment progress sit right at the top. Next to them are the links to the Figma mock-up and the test version as soon as they exist. The tabs hold the quote, a dated schedule, stage approvals, reports, the chat and documents. Everything about the project stays in one place instead of an inbox.

Invoices and the wallet, on your phone too

Invoices with their due dates and status sit in one place, and you settle an unpaid one with a single button from your wallet balance. You top up the wallet in advance and pay for the next stages from it. Payments in and out stay in the history. The panel works the same on a phone, so you can pay an invoice on the go.

VulCode tools inside the panel on a phone

Free tools without leaving the panel

The panel keeps the 32 tools from our site at hand: generators and calculators for Discord, Minecraft, businesses, developers and designers. They compute in your browser, so nothing you type reaches our server. Search by name or by what you need. Just as handy on a computer as on a phone.

About Us

VulCode is a Polish development studio. We build products that truly work - without compromising on quality or deadlines.

VulCode
Quality

Every line of code goes through code review. We never deliver something we would be ashamed of.

As fast as possible? With us it's doable.

We offer ready-made platforms that run your whole company - live from day one, on a monthly subscription instead of a big quote.

Quick Start

A ready platform to run your company. It works right away, out of the box - no weeks of work or rollout.

Minimal budget

No more spending thousands to start. Begin for pennies and watch your business grow.

Everything in one place

Everything handled from a single panel. Simple, intuitive and clear - you know how to use it at a glance.

Need more?

As your needs grow, the panel grows too. You can always move smoothly to a dedicated project, or order an extra feature in your panel.

Leave the tech to us

Hosting, updates, technical setup, backups and monitoring... all on us. Don't spend money where you don't have to.

Support, not a chatbot

Talk to real people who know your system and know how to help. We're here to keep everything running smoothly when you need it most.

Selected Works

See what we can do. Examples of our recent work where we combined thoughtful architecture with top-tier design.

Solutions for your industry

The same services look different in a hotel, on a game server and in a town hall. For every industry we have a ready set: what we build, what we integrate with and what the result looks like.

Hotels

Hotels

Direct bookings without portal fees

32 free tools, no account needed

Generators and calculators for server admins, developers, designers and businesses, plus 5 templates for ordering a project. All of them run straight in your browser and send your data nowhere.

From the first email to launch

The seven steps every project goes through.

Step 1 / 7

First contact and a quote

You write to us or we set up a short call. Instead of asking about your budget, we break the project down: what it does, who for, and what happens if we do not build it. A quote and initial scope come back within an hour.

The costliest changes are the ones nobody foresaw at the start - so we begin with questions, not a budget.

Step 2 / 7

Onboarding in the client panel

You get an account in the client panel where you see progress, files, invoices and tickets as they happen. You send over materials, a brand book and access, and we turn that into a dated schedule both sides see from day one.

Every decision, file and invoice in one panel - no more digging through email and chat threads.

Step 3 / 7

Prototyping the interface

Before any code runs, you see the layout and flow as wireframes of the key screens. We talk about where a button sits and in what order sections are read, not about colours. Changes here cost hours, not weeks.

Changing a layout on a wireframe takes minutes. The same change after launch takes days.

Step 4 / 7

Building the software

Work happens on a staging environment you can reach from day one, in a shared repository. Every week you get a short summary of what landed and what is in progress, so you never have to ask where things stand.

You see staging from day one - no waiting for a "big reveal" at the very end.

Step 5 / 7

Testing and a fix buffer

Before launch the product runs through a checklist we built over years of not wanting to make the same mistake twice. After launch a free time buffer covers small fixes - we do not invoice for every typo.

Every item on the checklist is a mistake that once cost us. That is why we keep it.

Step 6 / 7

Deployment and code handover

We set the launch date together so it surprises neither your users nor your team. After launch you get everything the project consists of: the repository, documentation and access. The code is yours - you do not have to come back to us to change anything.

You get the repository with its full commit history - you are never locked to a single company.

Step 7 / 7

Post-launch support

Launch does not end the collaboration. We monitor uptime and response times, and when something breaks we usually know before you do. Tickets stay in the same panel we ran the project in, so nobody starts the conversation from scratch.

Monitoring usually catches an outage before your user even notices it.

What clients say

A few words from the people we built for.

Vulcode.com built our website and we're very happy with the result. The site runs smoothly, is well optimised and displays correctly on every device. The whole rollout went without a hitch, and the source code is clean and ready for further development. We appreciate the punctuality and the technical support at every stage.
