LangSmith — from Free · 4.5★
LLM observability and evaluation platform for tracing, testing, and monitoring AI applications
Add to compare
What is LangSmith?
LangSmith is the LLMOps observability and evaluation platform built by LangChain for teams developing production LLM applications. It provides tracing, debugging, and evaluation for any LLM application — not just LangChain ones. Developers use LangSmith to trace every LLM call and tool ...
Read moreWhat reviewers like about LangSmith
- Framework-agnostic tracing works with any LLM provider (OpenAI, Anthropic, Mistral) and any orchestration framework, not just LangChain.
- Prompt Hub enables version-controlled prompt management with one-click rollback — replacing ad-hoc string management in code.
- Evaluation datasets and automated test runs enable regression testing across prompt versions, catching quality regressions before they reach production.
Where LangSmith falls short
- Built by LangChain, so teams using competing orchestration frameworks may find occasional rough edges in non-LangChain integrations.
- Trace storage costs scale with volume — high-frequency production applications need to budget carefully for trace retention.

Langfuse — from Free · 4.7★
Open-source LLM observability platform for tracing, evaluation, and prompt management
Add to compare
What is Langfuse?
Langfuse is an open-source LLM engineering platform for tracing, evaluation, prompt management, and metrics. It provides detailed traces of LLM application executions — capturing every LLM call, tool use, retrieval step, and agent action — and links traces to user sessions for production ...
Read moreWhat reviewers like about Langfuse
- MIT open-source license with Docker-based self-hosting means teams with data privacy requirements can run full LLM observability without sending traces to a third-party cloud.
- Generous free cloud tier (50k traces/month) covers most early-stage AI applications without any cost.
- Session-level trace grouping links multiple LLM calls into user sessions — enabling product-level analysis of where users encounter AI failures.
Where Langfuse falls short
- Smaller ecosystem and fewer integrations than LangSmith — some niche frameworks require manual instrumentation rather than automatic SDK integration.
- Self-hosting requires Docker knowledge and ongoing maintenance; small teams without DevOps support may prefer the managed cloud.

Helicone — from Free · 4.6★
Open-source LLM proxy with automatic logging, cost tracking, and caching in two minutes
Add to compare
What is Helicone?
Helicone is an open-source LLM observability platform that works as a proxy — developers route their LLM API calls through Helicone's gateway with a single URL change, and it automatically logs every request, tracks cost and latency, enables prompt caching, and provides rate limiting. ...
Read moreWhat reviewers like about Helicone
- Two-minute integration via proxy — change one URL and every LLM call is automatically logged with zero SDK changes or code instrumentation.
- Built-in prompt caching and rate limiting turn a logging tool into an active cost-reduction layer, not just observability.
- Supports every major LLM provider through a single proxy endpoint — no separate integrations per provider.
Where Helicone falls short
- Proxy architecture adds a network hop to every LLM call — latency-sensitive applications (real-time voice agents) may prefer SDK-based instrumentation.
- Less sophisticated evaluation and prompt management features than LangSmith or Langfuse — Helicone is strongest on logging/cost; weaker on systematic evaluation.
