What Caluma is
Caluma is a collaborative form and workflow builder for digitizing everyday business processes. Business users can configure complex forms, including applications and certifications, without technical knowledge. Fine-grained permissions support processes involving different users and roles, while declarative workflows handle processing and decision-making. Caluma is available for web use, through an API, or as self-hosted software. Its GraphQL API can query and change form and workflow entities, and GraphQL and OpenID Connect support integration with modern web applications. The product is customizable, and its client can use shareable components. Developers can use their preferred tools without an administrative interface. The code is released under GPL-3.0-or-later, and the Open-source Caluma plan costs nothing. Documentation recommends running it as a dedicated service and lists Docker and Docker Compose for the quickstart. The site directs people seeking technical help to contact a Caluma Supporter.
