Why Neptune is the Best Alternative to Sacred + Omniboard

Super easy setup and zero maintenance

Is it easy to set up and maintain Sacred backend and visualization dashboard for your entire team?

With Neptune you get all your experiment data saved and backed-up on hosted server or on-prem installation. You can manage user permissions and share experiments in the beautiful UI with no additional overhead. Powerful, simple, and available for you and your team in minutes.

Fast UI

Is your Sacred + Omniboard UI loading slowly when you have thousands of runs?

Neptune was built to scale and can support millions of experiment runs both in the back-end and front-end.

Dashboard Views

Can you save different experiment dashboard views in Sacred + Omniboard?

When you have multiple users working on many ideas the things you want to look at change… and so should your experiment dashboard.
Neptune lets you customize, change, and save experiment dashboard views depending on your needs.

Notebook Autosnapshots

Does Sacred + Omniboard snapshot your Jupyter notebooks automatically?

Neptune notebook integration automatically snapshots your .iipynb whenever you run a cell with neptune.create_experiment() in it. Whether you remember to submit your experiment or not everything will be safely versioned and ready to be explored.

Analyze Experiment Dashboard in Jupyter Notebook

Does Sacred + Omniboard let you fetch your experiment dashboard directly to a pandas DataFrame?

With Neptune you can fetch whatever information you or your teammates tracked and explore it however you like. We have some nice exploratory features, like HiPlot integration to help you with that.

metrics= ['eval_accuracy', 'eval_loss',...],
params = ['activation', 'batch_size',...])

Notebook Versioning and Diffing

Does Sacred + Omniboard let you track your exploratory analysis?

Neptune goes beyond the tracking of machine learning experiments and allows you to version your exploratory data analysis or results exploration as well!
Once it is saved in Neptune you can name, share, download or see diffs of your notebook checkpoints.

Sacred integration

Can you use Sacred Interface with Neptune back-end and UI?

That’s right. Neptune integrates with Sacred to give you the best of both worlds.
You can use Sacred interface for experiment tracking, log your experiment data directly to Neptune and enjoy the awesome UI that Neptune gives you. No need to set up MongoDB to store your data or fire up Omniboard dashboard on a dedicated server to explore it. Just append `NeptuneObserver` to your experiment and you are good to go.

No credit card required. Takes 5 minutes to get started.
