Software house — websites & custom software on demand
The software your business needs, built to order.
Koaris is a software house that builds websites and custom systems on demand: institutional sites, landing pages, web applications, internal tools and integrations. From briefing to launch, it is the same team — the people who hear your briefing are the ones designing the screens, writing the code and shipping.

What we build
Websites and custom software, on demand
Websites & landing pages
Institutional websites, landing pages and online storefronts designed to convert: fast to load, easy for your team to update, and optimized for search from day one.
Web applications & systems
Custom web apps and internal systems: customer portals, admin panels and dashboards built around how your team actually works — not the other way around.
Integrations & automation
We connect the systems you already pay for — CRM, payments, WhatsApp, ERPs, spreadsheets — so information flows between them without anyone re-typing it.
Care & evolution
After launch we host, monitor and keep your product improving, with agreed response times — or hand everything over to your team, documented and trained.
How it works
From briefing to launch, in four steps
- 01
Briefing
We listen to what you need, define the scope and send a proposal with timeline and price — you review it before anything starts.
- 02
Design
You see wireframes and the visual direction before we write code. Adjusting early is the cheapest way to get it right.
- 03
Build
We build in short cycles and show you a live environment from early on — you follow real progress, not status reports.
- 04
Launch
We deploy, watch the first days and keep improving your product. Or we hand it over to your team with docs and training.
Principles
One team, end to end
The people in your first meeting are the ones writing the code and launching your product.
Right-sized solutions
If an off-the-shelf tool solves it, we tell you. You only pay for custom software when it earns its cost.
No surprises
Scope, timeline and price are defined up front — and you always know what the next step is.
Koaris Tools
Free tools for everyday work
Between projects we design, build and maintain a free tool catalogue ourselves — same craft, no cost. No sign-up, nothing to install; most tools run entirely in your browser.
UTM Generator & Builder
Free UTM generator, builder and campaign URL creator: tag any link with utm_source, utm_medium and utm_campaign so analytics attributes every click.
WhatsApp Link Generator (wa.me)
Build a wa.me link that opens a chat with your number and an optional pre-filled message.
URL Encoder & Decoder
Percent-encode text for safe URLs, or decode an encoded string back to readable text.
HTML Text Encoder & Decoder
Turn special characters into HTML entities so they render literally — or decode entities back to text.
QR Code Generator
Make a QR code for a link, text, Wi-Fi network, email, phone number, SMS or contact card, and download it as SVG or a high-resolution PNG.
Background Remover
Cut the background out of a photo in your browser and download it as a transparent PNG.
Mailto Link Generator
Build a mailto: link with recipient, subject, body, CC and BCC already filled in.
