What is Hindsight agent memory?

It's a persistent vector store for semantically searching past production errors, powering Deja.dev to suggest fixes from history.

Does Deja.dev integrate with Sentry or Datadog?

Not natively yet—manual store calls for now, but webhooks could make it smoothly.

Is Hindsight agent memory free to use?

Core Hindsight is open-ish, but API keys and scaling cost real dollars via Vectorize/Groq.
