Custom Nextcloud apps
We build interfaces, rules, metadata and actions that respect platform permissions, conventions and release lifecycle.
Nextcloud development
Nextcloud can become part of your software, not another island.
We develop apps inside Nextcloud and integrate it with ERP, CRM, portals, identity providers and document services. We start with the process, use supported extension points and APIs, and manage the lifecycle with the platform.
Sustainable integration
The goal is not to connect two APIs. It is to keep work coherent.
An integration must establish which system is authoritative, how people and documents are identified, what happens to errors and duplicates, and who may retry an operation. Without those decisions, synchronisation hides inconsistencies instead of removing them.
We use Nextcloud extension mechanisms and interfaces such as WebDAV, CalDAV, CardDAV and available APIs when suitable. We avoid core patches and undocumented coupling. Code, configuration, migrations and dependencies enter the same testing, release, observability and update process.
What we build
Functions inside the platform and connections beyond it.
The solution may be a small automation, a complete app or a workflow distributed across several systems.
Workflow and automation
We connect document events to validation, assignment, notification and business steps with observable states and errors.
ERP, CRM and portals
We exchange master data, cases, documents and references without indiscriminately duplicating data or authorisation.
SSO and provisioning
We integrate identity, groups and revocation through compatible components while preserving service and emergency accounts.
Migration and classification
We automate import, metadata, structure and permissions with reconciliation and reporting for items that were not transferred.
Testing and compatibility
We maintain supported versions, automated tests, staging environments and upgrade plans for apps and dependencies.
Engineering method
Extend without compromising upgrades.
Every integration has a data owner, a contract and defined behaviour when something fails.
- Control 01
Design process and ownership
We define authoritative systems, identity, permissions, volumes, acceptable latency, errors and audit requirements.
- Control 02
Choose the extension point
We assess apps, APIs, protocols, events or queues for supportability, security, compatibility and maintenance.
- Control 03
Build and verify in isolation
We use separate environments, test data, code review and proportionate functional, security, migration and load tests.
- Control 04
Release and observe
We version changes and dependencies, enable logs and metrics, and test Nextcloud upgrades before production.
Upgradeability as a requirement
We do not modify core for a quick but fragile result.
We favour documented contracts and extension points. If a capability requires a compromise or relies on an interface with limited guarantees, we make the risk, required testing and exit strategy explicit before implementation.
Frequently asked questions
Clear answers before we define the scope.
01Can you connect Nextcloud to our ERP or CRM?
Yes, where the systems expose dependable interfaces or allow a controlled connector. We first define authoritative data, identifiers, permissions, frequency, error handling and reconciliation, then select appropriate APIs, events or batch processes.
02Do you build apps that run directly inside Nextcloud?
Yes. We can build apps with interfaces, rules and integrations that follow the Nextcloud architecture. Scope, distribution, licensing, supported versions and maintenance responsibility are agreed with the customer.
03What happens to custom apps during an upgrade?
We maintain a compatibility matrix and test apps, migrations and integrations in a separate environment. If a new release introduces incompatible changes, we plan the adaptation before it reaches production.
04Do customers retain access to their data and code?
We define ownership, licensing, repositories, documentation, credentials and export contractually. We design an exit path so that data and operations do not depend on knowledge that cannot be transferred.
