Instant Postgres branches so coding agents can test safely
Create a 1:1 copy of any Postgres database in under six seconds and keep that speed even at terabyte scale, so agents never wait on test environments.
Every branch is isolated at the compute and storage level, meaning experiments, migrations, and data cleaning can never reach or damage production.
Clones only consume storage for the changes actually made, instead of duplicating the full dataset for every branch.
Branch compute scales with agent workloads and drops to zero when idle, so you never pay to keep idle test databases running.
Agent observability, evaluation, and continuous improvement for production AI
Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
Excels at experiment tracking and model registry workflows, but is less purpose-built for real-time LLM production observability.
