Braintrust - The active observability platform for agents

Braintrust (braintrust.dev) is filed under AI and SaaS in the LinkPreview gallery. Its meta title is 57 characters, right in the 50–60 range that Google tends to show in full. The description runs 162 characters, past 160, so the end will likely be cut off on Google. The Open Graph image is 560 × 294 pixels, the right 1.91:1 ratio but below the recommended 1200 pixels wide.
