vsFaultmap vs LangSmith
LangSmith reads the runs. Faultmap reads the goal, personas, data, and tools, and maps the breaks before the first run exists.
Faultmapbefore the buildLangSmithafter the build
When it runs
Before the build, in the design phase
After the build, on live traces
What it needs
Your goal, personas, data, and tools
A running agent and recorded traces
What it produces
A map of where it breaks, plus the first test suite
Eval scores and regression signals on what already ran
The question it answers
Where will this agent break, before I build it?
How is my built agent doing?
We do not replace LangSmith. Faultmap runs one step earlier. Keep using LangSmith after the build.
What LangSmith is
Traces, evaluates, and monitors agents you have already built on top of your runs.
Tracing and evals
Where Faultmap fits with it
- Run Faultmap in design to catch the breaks before you build.
- Build the agent against the test suite Faultmap hands you.
- Use LangSmith after launch for tracing and evals.
Map the breaks before LangSmith ever sees them.
