Clear quote, no surprises
After the scoping session, you know what you're getting and what it costs: a fixed price where possible, an honest time estimate where bespoke work needs room. No open-ended contracts, no unexpected change requests.
Custom web application
A web application that does exactly what your process needs.
No off-the-shelf package that almost fits. We build from scratch — clearly scoped, in short iterations, with a clear quote you know upfront.
Why “Paceline”?
A paceline is a group of riders taking short turns at the front: high pace, faster together than anyone alone. That's how we build software — short iterations, visible progress every week.
Tap the riders for an attack
From sketch to production
Design, development, hosting and monitoring — all in one engagement. One point of contact, also after launch.
Scalable and maintainable
Proven technology that has been running in production for years, easy to extend as your organisation grows.
Services
Everything a web application needs
From first sketch to a running production environment — under one roof.
Custom web applications
Complete Rails applications that do exactly what your process needs — from a sleek web app to full-fledged business software. Not an off-the-shelf package that almost fits, but software that grows with your organisation.
Payments & webhooks
Stripe, iDEAL and Bancontact, including webhooks that process payment status reliably. From one-off payments to recurring invoicing flows.
Member & content platforms
Web applications with roles and permissions: from a coaching academy to a client portal. Everyone sees exactly what is meant for them.
Integrations & APIs
Connections with calendars (iCal), maps, PDF generation or your existing systems. Data flows automatically to where it's needed.
Hosting, deploys & maintenance
Docker containers on European servers — your data stays within the EU, no US cloud. With monitoring, updates and daily cloud backups that keep 30 days of snapshots, so your database is always safe — and changes go live in minutes, not months.
Websites & restyling
Got a site that feels dated? We bring it right back up to speed with a fresh, modern restyling built to the latest web standards — fast, accessible and pixel-sharp on every screen.
Modern UX without heavy frameworks
Fast, accessible interfaces built with Hotwire (Turbo + Stimulus). The smoothness of an SPA, without the complexity and maintenance burden.
Web shops & e-commerce
Full-fledged web shops in Rails: a product catalogue with variants and stock, a smooth cart and a secure checkout. Including a gated admin backend with two-factor authentication — from storefront to order fulfilment.
AI & MCP integrations
Make your data securely available to AI systems. Alongside classic REST APIs we build MCP servers (Model Context Protocol), letting assistants like Claude, Copilot and ChatGPT work directly with your application — under your control, with your roles and permissions.

Frequently asked questions
What does it cost to have a web application built?
Costs depend on scope and complexity. After a free intro call we put together a fitting quote — a fixed price where possible, an honest time estimate otherwise. You know upfront where you stand, no open end.
How long does it take to build a web application?
A simple web app is often live in four to eight weeks. More complex systems take longer. Paceline works in short iterations, so you have visible results every week.
Can you take over or extend an existing application?
Yes, Paceline takes over and extends existing applications. Every engagement starts with a technical analysis to map the current state and risks.
What kind of web applications do you build?
From modern business websites and membership platforms to full ERP systems, web shops and integrations with external APIs. All fully custom-built.
About Paceline
Why work directly with the developer?
Paceline Software builds custom web applications from Someren, in the Eindhoven region — from modern websites to complex ERP and maintenance-planning (MJOP) systems — and brings that experience together in its own products like MeSyncFlow and RouteFrame. Small and independent, with deliberately few layers between you and the code.
Paceline Software
Software for the long run, built at pace.
-
Direct contact
You talk directly to the developer who builds your software. No account managers, no translation layers, no noise.
-
Proven technology
Ruby on Rails and Hotwire: mature, maintainable technology that has been running production for twenty years — and will be ten years from now.
-
One point of contact
From first pixel to deploy: one steady point of contact who oversees the whole project and is accountable for the result — no handoffs between departments.
