Indigo ELN

Indigo ELN is a chemistry-oriented electronic lab notebook for teams that need structured experiment records alongside molecular editing and reaction tools. It is best suited to organizations able to deploy and administer web software themselves. Its strongest case is a capable, free chemistry record system, while teams wanting an immediately accessible hosted evaluation should look elsewhere.

Overview

Indigo ELN structures work through projects, notebooks, experiments, and components, giving research groups a consistent hierarchy for storing and sharing chemistry information. Experiment templates and additional components can be created without altering the core code, so recurring procedures can be adapted to a group’s workflow without maintaining a fork.

The application is web based and can be deployed from a Docker image. Documentation covers local Docker installation and AWS deployment, which suits teams with infrastructure staff or an external deployment partner. The demo environment is currently unavailable while work continues toward a publicly accessible version 3.0 environment, so prospective users cannot rely on an online trial before planning deployment.

Key features

Chemistry tools and discovery

Ketcher provides chemical structure editing, while Indigo renders reactions and calculates chemical properties. These are meaningful advantages for chemistry-focused notebooks, where structures and reactions need to sit alongside experimental records rather than remain in separate tools. Search works across entity attributes; adding BingoDB enables searches by product structure or reaction scheme, a more specialized capability for teams working with substantial chemistry collections.

Records, permissions, and exchange

Role-based authorities and access control lists can be applied to projects, notebooks, and experiments. That gives administrators a way to separate access between research areas and individual records. Users can print project, notebook, and experiment pages to PDF and import or export SDF files, covering practical reporting and chemical-data exchange needs.

Integration and signatures

API access supports connections to customer services, databases, and electronic-signature services. Electronic signatures are supported, making the platform more viable for workflows that require signed records, although implementation work may be needed to connect the surrounding systems.

Pricing

The free core removes subscription cost and makes Indigo ELN practical for teams prepared to operate the software themselves. It does not establish a hosted service, seat allowance, storage quota, trial period, or renewal schedule. EPAM separately offers customization, integration, support, and maintenance priced to individual requirements; those services are relevant when a team lacks the capacity to implement or maintain its own deployment. The GPLv3 distribution also comes without warranty, an important consideration for organizations that require contractual assurance.

Platforms

Indigo ELN is available as a web application with API and self-hosted deployment options. Docker-based installation and AWS deployment documentation make self-managed operation the practical path. It is not presented as a native desktop or mobile application.

Who it's for

Choose Indigo ELN if your laboratory needs chemistry-aware records, structure and reaction handling, configurable templates, controlled project access, and chemical-data export without a license fee. It is particularly suitable for research groups that can run Docker or AWS infrastructure, connect APIs, and manage their own operational support.

It is a weaker fit for teams that need a ready-made hosted workspace, an immediately testable demo, or warranty-backed commercial terms. Those requirements add deployment and procurement concerns that the free core does not resolve.

Pros and cons

Pros

• Free core under GPLv3: teams can adopt the central ELN without a software charge.
• Purpose-built chemistry tooling: Ketcher and Indigo combine structure editing, reaction rendering, and property calculations in the record workflow.
• Flexible record design: templates and components can be added without changing core code.
• Useful controls and interchange: project-level permissions, electronic signatures, PDF output, and SDF import/export support governed workflows.
• Integration surface: APIs and BingoDB integration extend connections and chemistry search.

Cons

• No current demo environment: teams cannot evaluate the application through a public instance while the version 3.0 environment is being prepared.
• Deployment responsibility: the web product’s documented Docker and AWS paths still require infrastructure and administration.
• No warranty: GPLv3 distribution is explicitly provided without warranty.
• Professional services are bespoke: customization, integration, support, and maintenance require individually priced arrangements.

Alternatives

Electronic Lab Notebook Software is the broader category guide for comparing notebook products.

Pick LabArchives instead if you want Android, iOS, desktop, and web coverage, a free tier with two owned notebooks and 1GB per user, plus a free trial.

LabCollector ELN is a better alternative when a lifetime free startup package with three users, 1,000 data records, and one recipe/SOP matches your scale.

Choose eLabFTW instead for self-hosted AGPLv3 software with no features behind a paywall, provided you can supply server hosting and administration.

SciNote suits a single user wanting a dedicated free workspace, while premium plans use quote-based pricing.

RSpace is an option for teams considering self-installation through its open-source plan, with migration limits around Global IDs, digital signatures, and full audit history.

Benchling Notebook is worth considering for academic researchers seeking a free Notebook and Molecular Biology plan, or businesses needing a customized industry solution.

LabID provides another free, open-source, self-hosted route.

Phoenix ELN is a no-cost option when a Windows-only application is sufficient.

Verdict

Indigo ELN is a strong choice for chemistry research groups that want a free, extensible ELN with integrated structure, reaction, search, permissions, APIs, and SDF/PDF exchange. Look elsewhere if your priority is a hosted product you can try immediately, or if your organization needs warranty-backed support rather than self-managed deployment and optional bespoke services.
