In their own words
Falcon Builder
Falcon Builder is a no-code platform for creating and deploying AI agents as hosted chat, forms, website chat widgets, WhatsApp, or SMS experiences. Users can start from natural-language instructions, adapt templates, or build workflows with drag-and-drop nodes, code, APIs, and databases. AI Wingman can add nodes, adjust configurations, help debug, and explain workflow logic in conversation. The workflow engine provides execution history, error handling, retries, replay, and debugging. Listed connections include Outlook, Twilio, Retell, GoHighLevel, Google Sheets, databases, AWS S3, REST APIs, and webhooks; model providers include OpenAI, Anthropic, Gemini, and Ollama. A Slack review workflow can let a teammate approve or revise a draft before execution continues. The Free plan includes up to five workflows and 250 executions per month. Pro costs $29 a month; Business costs $249 a month. It supports web and API use.
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.
