Overview

Overview

LibreSign brings electronic PDF signing to the Nextcloud ecosystem, allowing users to apply digital signatures without leaving their file storage environment. It integrates with GLPI to sign tickets and offers admin‑configured approval workflows, making it suitable for internal document control and audit trails.

Capabilities & Deployment

The app supports standard PDF signatures, exposes a RESTful API for programmatic signing, and can be installed via the Nextcloud app store. Once deployed on a Nextcloud server, it leverages existing authentication and storage, eliminating the need for separate signing platforms. Administrators can define workflow rules to automatically approve or reject files, while developers can extend functionality through the documented API.

Who Benefits

Teams already using Nextcloud for collaboration, IT service desks using GLPI, and organizations that need lightweight, self‑hosted e‑signature capabilities will find LibreSign a practical addition to their workflow.

Highlights

Pros

  • Seamless integration with existing Nextcloud deployments
  • Open‑source code under AGPL‑3.0 for transparency and extensibility
  • Workflow engine enables automated document approval
  • API access allows headless and third‑party integrations

Considerations

  • Limited to PDF files; other formats are not supported
  • Requires a running Nextcloud instance, adding infrastructure overhead
  • AGPL licensing may affect commercial redistribution

Fit guide

Great for

  • Organizations already using Nextcloud for file collaboration
  • IT service teams that need to sign GLGL tickets for audit purposes
  • Businesses seeking a self‑hosted, scriptable PDF signing solution
  • Developers wanting to embed signing into custom workflows via API

Not ideal when

  • Use cases requiring legally qualified electronic signatures
  • Environments without Nextcloud or similar self‑hosted platforms
  • Projects that need to sign non‑PDF document types
  • Companies that cannot accommodate AGPL licensing constraints

How teams use it

Contract signing within Nextcloud

Legal teams can apply digital signatures to PDF contracts directly from the shared folder, preserving version history.

Automated purchase‑order approval

Admins define a workflow that signs and moves approved purchase orders, reducing manual hand‑off.

GLPI ticket audit trail

Support staff sign tickets after resolution, creating a verifiable record for compliance audits.

Headless signing via API

External systems trigger PDF signing programmatically, enabling integration with CI/CD pipelines or custom portals.
