TensorBoard
vs
neptune-logo

Your experiments have grown to 100s of runs. Your team has grown too.
Sluggish performance at runtime and clumsy workarounds for collaboration
are slowing you down. It’s time you tried Neptune.

Commercial Requirements

Commercial requirements chevron
Standalone component or a part of a broader ML platform?

Open-source platform which offers four separate components for experiment tracking, code packaging, model deployment, and model registry

Open source tool which is a part of the TensorFlow ecosystem

Standalone component

Is the product available on-premises and / or in your private/public cloud?

Tracking is hosted on a local/remote server (on-prem or cloud). Is also available on a managed server as part of the Databricks platform

TensorBoard is hosted locally. No
TensorBoard.dev is available on a managed server as a free service

Is the product delivered as commercial software, open-source software, or a managed cloud service?

Open-source

TensorBoard is open-source, while TensorBoard.dev is available as a free managed cloud service

Managed cloud service

General Capabilities

Setup chevron
What are the infrastructure requirements?

No requirements other than having mlflow installed if using a local tracking server. Check here for infrastructure requirements for using a remote tracking server

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

No special requirements other than having the neptune-client installed and access to the internet if using managed hosting. Check here for infrastructure requirements for on-prem deployment.

How much do you have to change in your training process?

Minimal. Just a few lines of code needed for traking. Read more

Minimal if already using the TensorFlow framework, else significant

Minimal. Just a few lines of code needed for tracking. Read more

Does it integrate with the training process via CLI/YAML/Client library?

TensorBoard is available both as a client library and CLI. TensorBoard .dev is available only as a CLI

Yes, through the neptune-client library

Does it come with a web UI or is it console-based?
