Arex — automated API testing that captures real user traffic and replays it as test cases. No hand-written test suites to maintain, no costly throwaway test environments. Trusted by teams at Trip.com, Yeahka, United Imaging, Lexin, ZTO, and others.
thelake — an open-source AI evidence lake on DuckDB, a LangSmith / Datadog alternative built for long-term storage of full payloads (prompts, responses, tool I/O, HTTP bodies) as open Parquet — about 200x cheaper than index-heavy observability. OTLP in, DuckDB SQL out. It's the durable evidence foundation underneath Softprobe Agent QA.
