📣 BIG NEWS: Neptune is joining OpenAI! → Read the message from our CEO 📣

To all researchers using TensorBoard:

Say hello to more sophisticated experiment tracking

You have great visualization options for your research projects.
But Tensorboard’s other features are limited.
Add Neptune and gain the ability to:

  • Collaborate smoothly (no screenshots required)
  • Track experiments at scale (without the screen lags)
  • Compare results with ease (bye-bye cluttered UI)

Trusted by researchers at enterprises & universities training models at scale

icon Advanced experiment tracking features

More metadata. More precision. More possibilities.

You love Tensorboard’s charts and graphs. You’d also love more features to accurately track and compare your model training.
Get the best of both worlds by using Neptune as well.

Including:

And much more…

icon Painless collaboration

Stop sharing work with so many screenshots Start creating custom reports in a click

“What sets Neptune apart for us is the ease of sharing logs. The ability to send a Neptune link in Slack and let my coworkers see the results for themselves is awesome.”
– Greg Rolwes, CS Undergrad at Saint Louis University

Will scale. Won’t fail.

“We originally used Tensorboard and had scalability issues with many runs. With Neptune, we can go through 1,000 model designs and everything seems to work fine, work well, right out of the box.”
– Brian Geier, Data Scientist at TENET 3

Setup chevron
Infrastructure requirements

Minimal setup—install the Python client and ensure internet access (for managed hosting). Self-hosting requires additional infrastructure; see requirements here.

Basic logging can be done by having just TensorBoard installed. However, most advanced logging also requires TensorFlow to be installed.

Integration with the training process

A few lines of code via the Neptune Python library.

A few lines of code via client library and CLI.
