Nextcloud Apps · 100% self-hosted

- WCAG 2.1 AA targeted
Free to install. Paid to fit your business. Use the apps free of charge — and hire us when you need consulting, requirements engineering, or custom Nextcloud development to make them work exactly the way your organisation does.

Why these apps
Built for organisations that care about data and the law.
No external SaaS calls. No usage telemetry. No surprise account creation. Just clean Nextcloud apps that respect your users and your auditors.
Auditable by design
Action logs, snapshots, and immutable closures mean you can answer who-did-what-when months later.
Accessibility & UX
Each app targets WCAG 2.1 AA. Full keyboard support, semantic markup, responsive layouts from 320 px.
Honest licensing
AGPL-3.0-or-later. Read the code, audit it, fork it. Use it free of charge in your organisation.
Security first
Server is the source of truth for calculations. Inputs are validated; permissions are role-aware.
Privacy by default
The apps send no telemetry. This website loads no third-party fonts or ad trackers and sets no cookies — only self-hosted, cookieless visitor statistics, with an opt-out.
Work with us
Free apps. Paid expertise. Honest licensing.
The five apps are free to install, free to use, and free to fork — that is the AGPL deal. When you need them to fit a specific workflow, audit, or industry, we are the people who built them. Tell us what you need; we tell you what it takes.
