The best ELN software replaces paper lab notebooks with a searchable, shareable digital record of experiments, protocols and results, with timestamps and signatures that stand up to audit. Academic labs often start with free open source notebooks, while biotech and pharma teams need notebooks tied to LIMS, inventory and regulated workflows. Ten options follow in no particular order.
A paper lab notebook is a wonderful thing until you need to find something in it. Which experiment used that batch? Who changed the protocol, and when? Was it written up on the day, or a week later?
An electronic lab notebook answers those questions in seconds. The ten tools below are listed alphabetically and in no particular order, and every description comes from the vendor's own website, read this week. If your lab is in manufacturing or pharma, my piece on making pharmaceutical manufacturing safer is a useful read alongside it.
Electronic lab notebooks at a glance
I checked the free plan column on each tool's own website, as of Oct 2026. Yes means the site names a free plan, a free version, a free account or an open source release. Trial only means a time-limited trial. Not stated means the pages I read named neither, even where there's a button inviting you to try it, so check the vendor's page before you sign up.

Ten ELN options to consider
Benchling
Best for: Biotech R&D teams who want a notebook that turns unstructured notes into analysis-ready data connected across the R&D lifecycle.
CDD Vault
Best for: Drug discovery teams who want registration, assay data and an ELN add-on in one scientific data management system, with a free trial.
eLabFTW
Best for: Academic and research labs who want a free, open source notebook to install themselves, with signed and timestamped entries.
LabArchives
Best for: Universities, startups and government labs who want a modern ELN, with a separate edition for education and teaching.
Labfolder
Best for: Labs who want an intuitive, compliant notebook that tracks every change, now part of SciSure along with Labregister.
Labguru
Best for: Biotech, pharma and foodtech labs who want an ELN alongside LIMS, inventory and equipment management.
RSpace
Best for: Research institutions who want an open source, collaborative notebook with sample management and links to research data infrastructure.
Sapio ELN
Best for: Scientists who want an AI-native notebook that flexes to each experiment and connects to a no-code LIMS.
SciNote
Best for: Biopharma, diagnostics and academic labs who want protocol management, team collaboration and 21 CFR Part 11 compliance features.
Scispot
Best for: Regulated labs and CROs who want ELN, LIMS and data tools on one connected platform for a more automated lab.
Which ELN suits which lab
- Free, self-hosted notebooks: eLabFTW or RSpace.
- Universities and teaching labs: LabArchives.
- Biotech R&D data: Benchling.
- Drug discovery data: CDD Vault.
- Regulated work and Part 11 features: SciNote or Labfolder.
- Notebook plus LIMS and inventory: Labguru, Sapio ELN or Scispot.
What FDA's Part 11 guidance means for an ELN
The US Food and Drug Administration's guidance on Part 11, which covers electronic records and electronic signatures, says that while it re-examines part 11 it doesn't intend to take enforcement action on the validation, audit trail, record retention and record copying requirements as explained in that guidance. It also says records must still be maintained or submitted in line with the underlying predicate rules.
So the rules that require a record in the first place still apply. If your lab does regulated work, pick an ELN that keeps trustworthy, retrievable records and signatures, and ask your quality team which features you need switched on.

I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Open source, academic or enterprise?
Open source notebooks are free to install and run yourself. They suit academic groups with IT support, and they keep your data under your own control.
Academic and general ELNs are hosted for you, easy to roll out across a department and often come with teaching editions.
Enterprise R&D platforms connect the notebook to sample registries, inventory, LIMS and analysis. They're heavier, but they turn lab notes into structured data your whole organisation can use.
Lab records feed into wider quality work, and this list of quality management software weighs up systems that run it.
Questions to ask before you choose
- Can entries be signed and timestamped?
- Does it keep a full history of every change?
- Will it connect to your instruments and LIMS?
- Can you export everything in an open format?
- Does it support the protocols and templates you use?
- Where is the data hosted?
Labs that monitor processes will find statistical process control tools useful for control charts and alerts.
Signs your lab needs an ELN
- Finding an old result takes hours. Make notes searchable.
- Protocols drift between people. Use shared templates.
- Handwriting causes errors. Record digitally.
- Audits mean digging through boxes. Keep signed digital records.
Do you make lab or research software? Tool makers can ask to be considered for a featured place on this list.
My plain advice on ELN software
Run a pilot with one group for a month, using the notebook for every experiment, not just the easy ones. You'll learn more from the first messy week than from any demo, and you'll know whether people will keep using it.
Before you commit, check you can get all your data out again in a usable format. If documents are part of the picture, my list of document management software covers storing the files around your experiments.
Frequently asked questions
What is ELN software?
ELN stands for electronic lab notebook. It's software that replaces paper notebooks with a digital record of experiments, protocols and results that's searchable, shareable and timestamped.
Is there a free electronic lab notebook?
Yes. Some notebooks are free and open source, so you can install and run them yourself. Check the free plan column above for the ones I found.
What's the difference between an ELN and a LIMS?
An ELN records experiments and observations. A LIMS manages samples, tests and lab workflows. Many platforms now offer both.
Does an ELN need to meet 21 CFR Part 11?
If your work falls under FDA predicate rules, your records must still be kept as those rules require. Several ELNs offer Part 11 compliance features for regulated labs.
Can I move from paper notebooks to an ELN gradually?
Yes. Many labs start with new projects in the ELN and scan or reference older paper notebooks as needed.
Who owns the data in a hosted ELN?
Check the vendor's terms. Most say your organisation owns its data, but export options vary, so test them before you commit.
