The #1 AI engineering platform

Basalt is where teams prototype, evaluate,
and monitor AI features.
THE REALITY TODAY

Building a POC is easy. Production-grade AI is another story.

You have to deal with edge cases.

You’ve tested your agent on a few cases, great! But your users will be more creative. Good AI requires constant iteration.

Iteration is too slow.

Improving your AI product means constantly refining prompts and tools. The problem? They’re buried in your code.

You need to include non-tech teams

Let non-tech teams craft prompts, review and annotate outputs. AI engineering requires a collaborative process.
