Getting started

Basalt helps you manage prompts, datasets, experiments, and observability for AI features — with an API and SDKs. Create an account
Basalt Python SDK is documented in v1. If you’re using TypeScript/JavaScript, the v1 SDK is not available yet — use the v0 (archive) docs.

​
The 4 pillars

Prompts

Host and version prompts centrally, fetch them at runtime, and roll out changes safely.

Datasets

Store and retrieve structured examples for evaluation, regression, and experimentation.

Observability

Trace end-to-end AI workflows with start_observe and observe (OpenTelemetry-based).

Experiments

Run and compare variants, attach evaluations, and iterate with confidence.
