Indigo ELN vs Sapio ELN

Indigo ELN is a free electronic lab notebook for creating, storing, retrieving, and sharing chemistry records. It organizes work into projects, notebooks, experiments, and components, while allowing experiment templates and added components without changing the core code. Ketcher provides chemical structure editing, and Indigo handles reaction rendering and chemical property calculations. Searches can use entity attributes, or product structures and reaction schemes with BingoDB integration. APIs connect customer services, databases, and electronic signature services. Role-based authorities and access control lists govern projects, notebooks, and experiments. Pages can be printed to PDF, and SDF files can be imported or exported. The system runs on the web and can be self-hosted; the maker says a Docker image is available, with documented local Docker and AWS deployment. The core product is free under GNU GPL version 3 and provided without warranty. EPAM offers paid customization, integration, support, and maintenance. The demo environment is unavailable while work continues toward a public version 3.0 environment.
