About

Unexpected results happen all the time. With full visibility into the entire chain sequence of calls, you can spot the source of errors and surprises in real time with surgical precision. Software engineering relies on unit testing to build performant, production-ready applications. LangSmith provides that same functionality for LLM applications. Spin up test datasets, run your applications over them, and inspect results without having to leave LangSmith. LangSmith enables mission-critical observability with only a few lines of code. LangSmith is designed to help developers harness the power–and wrangle the complexity–of LLMs. We’re not only building tools. We’re establishing best practices you can rely on. Build and deploy LLM applications with confidence. Application-level usage stats. Feedback collection. Filter traces, cost and performance measurement. Dataset curation, compare chain performance, AI-assisted evaluation, and embrace best practices.

About

Runheed is a hosted error-tracking service for developers who use AI coding agents to build and maintain production applications. Its Node.js/TypeScript and Python SDKs report exceptions that Runheed groups by fingerprint with stack traces, breadcrumbs, request details, environment, release, and optional agent-session context. The remote Model Context Protocol (MCP) server lets compatible agents search error groups, inspect full context and trends, check project health, and resolve errors with a note describing the fix. If a resolved error recurs, it reopens with its previous resolution note. Framework setup is available for Express, Next.js, Fastify, FastAPI, Django, and Flask, while an HTTP endpoint accepts reports from other languages. Email alerts notify users when new error types are detected. The Solo plan starts at $29 per workspace per month and includes a 7-day trial.
