We design and deploy production-grade, self-hosted tooling for SMEs — so your data stays in the EU, under your control, with no per-seat SaaS pricing.
End-to-end delivery of self-hosted business tooling — from initial design through deployment, configuration, and ongoing maintenance.
We deploy and maintain open-source alternatives to SaaS products — customer support inboxes, CRMs, communication platforms — on your own servers or a VPS under your control.
Connect WhatsApp Business, email, and live chat into a single unified inbox. We handle the WhatsApp Cloud API setup, webhook configuration, and channel routing.
Infrastructure as code, automated deployments, SSL, backups, and monitoring. We keep your stack running and updated so you can focus on your business.
Current project: self-hosted Chatwoot deployment with WhatsApp Business integration for a Dutch notary practice — customer queries handled in one inbox, data staying on EU servers, zero per-seat licensing costs.
SaaS is convenient — until your data lives in a US data centre, your monthly bill scales with your headcount, and your vendor decides to sunset the product. Self-hosting fixes all three.
Your servers, your jurisdiction. GDPR compliance is structurally simpler when you control where data lives.
No terms-of-service changes, no surprise pricing tiers, no risk of a vendor pulling the plug on your core tooling.
Pay for server capacity, not per seat. As your team grows, your infrastructure cost stays flat.
Open-source software means you can migrate, fork, or hand off maintenance to anyone — not just us.
