In their own words
Bifrost
Bifrost is an AI gateway and control plane for directing, governing, and securing traffic involving model calls, MCP tools, and agents. It connects to more than 20 AI providers through one OpenAI-compatible API. Routing tools include weighted load balancing, retries, automatic provider failover, and semantic caching. Virtual keys let teams apply permissions, budgets, rate limits, and routing rules by consumer. Bifrost can connect with external MCP servers and present their tools to clients such as Claude Desktop. Its documented SDK integrations include OpenAI, Anthropic, Google GenAI, LiteLLM, and LangChain. Request monitoring, Prometheus metrics, and OpenTelemetry tracing integrations provide observability. The free OSS edition is for developers, small teams, and self-managed deployments; it can run via NPX, Docker, Kubernetes, or Go binary. Enterprise adds SSO, role-based access, audit logs, guardrails, vault integrations, and private VPC deployments. Enterprise pricing is custom, with a 14-day trial on an enterprise license.
LangSmith
LangSmith is a commercial agent-engineering platform for building, evaluating, deploying, monitoring, and improving AI agents. It supports offline evaluations on curated datasets and real-time scoring of production interactions. Evaluation methods include human review, heuristic checks, LLM-as-judge evaluators, pairwise comparisons, and custom Python or TypeScript evaluators. Annotation queues route runs to subject-matter experts for feedback that can calibrate evaluations, improve prompts, or augment datasets. The Playground compares prompt versions or model providers, and LangSmith chat can auto-improve prompts. Observability includes agent and retrieval tracing, token and general cost tracking, trajectory monitoring, online evaluations, and webhook or PagerDuty alerts. Traces can arrive through SDKs or an API from LangGraph, custom Python, or other stacks; SDKs are listed for Python, TypeScript, Go, and Java. Hosting ranges from cloud to hybrid and self-hosted Enterprise options. The Developer plan costs nothing, Plus costs $39 a month, and Enterprise pricing is custom.
