Indigo ELN review
A chemistry-focused ELN with structured experiments, chemical search, APIs, and exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Indigo ELN is a web-based, open-source electronic lab notebook for scientists conducting chemistry research. It organizes projects, notebooks, experiment templates, experiments, chemical structures, reaction information, compound records, and batch records. User, role, authority, and access-control management support controlled sharing, while component-based experiment structures allow teams to shape templates around their work. Its strongest fit is for chemistry-focused labs that want an open-source foundation they can manage and customize.
The Core Indigo ELN plan is presented as a free, open-source core product under GPLv3. It includes projects, notebooks, experiment templates, experiments, search, PDF printing, SDF import/export, and APIs for external services and databases. The published plan structure keeps the product focused rather than dividing capabilities across multiple paid tiers. Indigo ELN 2.0 is described as free, and the vendor’s news page reports Indigo ELN 2.1 released on February 20, 2025.
Chemistry functionality is the main differentiator. Integrated Ketcher supports chemical structure editing, while entity, product-structure, and reaction-scheme search help organize scientific information. Compound and batch records add structure to registration workflows, and APIs can connect customer services, databases, external compound registration, structure-search, and electronic-signature services. Teams should also account for self-managed deployment and the project’s stated transformation, which may bring code and documentation inconsistencies. Indigo ELN suits organizations prepared to manage and adapt an open-source chemistry system; teams seeking a turnkey, broadly packaged ELN may prefer another option.
Indigo ELN pros and cons
- Where it wins
- Open-source core with projects, notebooks, and experiment templates
- Chemical structure editing, reaction search, and compound records
- APIs plus PDF and SDF export for connected workflows
- Where it doesn't
- Self-managed deployment requires organizational setup and customization
- Web-only access may not fit teams needing native applications
- The project is undergoing transformation with possible code inconsistencies
