## Choose when

### Choose logfire if…

- logfire is primarily Python; tensorboard is TypeScript.
- License: logfire is MIT, tensorboard is Apache-2.0.
- Tags unique to logfire: agent-observability, ai, ai-observability, evals.
- Use Logfire when your project requires comprehensive observability tailored specifically for large language models (LLM) and agent-based systems.

### Choose tensorboard if…

- tensorboard is primarily TypeScript; logfire is Python.
- License: tensorboard is Apache-2.0, logfire is MIT.
- Pricing: There is no direct cost associated with using TensorBoard through its open-source version under the Apache 2.0 license..
- Tags unique to tensorboard: dashboard, tensorboard, visualization.
- tensorboard ships Docker support for self-hosted deployment.
- Use TensorBoard when you are working with TensorFlow projects to leverage its specialized plugins for detailed graph visualizations and tensor data insights.

## When NOT to use logfire

- Avoid using Logfire if your application does not involve LLMs or agent systems, as its features are finely tuned for these specific technologies.
- Do not use if you prefer tools with broader application across different technology stacks rather than a specialized toolkit focused on Python and related frameworks.

## When NOT to use tensorboard

- Avoid TensorBoard if your machine learning setup does not utilize TensorFlow, as it provides limited functionality without a TensorFlow installation.
- Do not use TensorBoard when your application specifically requires log directory access on Google Cloud Storage, as this feature is absent in environments lacking TensorFlow.
