In their own words
Future AGI AI Evaluation SDK
Future AGI AI Evaluation SDK is an open-source platform for evaluating, simulating, optimizing, monitoring, and protecting AI agents. Its evaluation options include heuristic, code, LLM-as-judge, and agentic methods, with templates and CI/CD support. traceAI instrumentation converts LLM calls, tool use, retrieval, and chain steps into OpenTelemetry spans. Simulation supports text and voice tests using personas and scenarios; the Free plan includes 1M text simulation tokens and 60 voice minutes per month. The integrations page lists 79 integrations and SDK packages for Python, TypeScript, and Java, including OpenAI, Anthropic, Google GenAI, Vertex AI, AWS Bedrock, and Azure OpenAI. The Apache 2.0 platform offers Docker and SDK self-hosting options. Future AGI says Docker Compose self-hosting keeps traces, datasets, evaluations, and model calls within the customer's network. The platform is presented for startups and enterprise teams building and operating AI agents, with API, web, self-hosted, Linux, macOS, and Windows options. Free usage pauses at its cap; pay-as-you-go usage continues and may incur overage charges.
LangWatch
LangWatch is an AI agent engineering platform for teams preparing agents for production. Simulations cover multi-turn conversations, tool use, recovery, and business outcomes before launch. Evaluations can run on datasets, production traffic, or in CI/CD workflows that gate merges. Traces show agent steps alongside cost, tokens, duration, errors, evaluations, and annotations. Integrations include Python and TypeScript SDKs, OpenTelemetry, REST ingestion, model providers, and frameworks such as LangGraph, LangChain, CrewAI, and DSPy. Voice-agent testing supports OpenAI Realtime, Gemini, ElevenLabs, Google Live API, Pipecat, WebSocket bots, and Twilio. Deployment options are managed cloud, self-hosted, and hybrid; self-hosting uses Docker Compose and the customer’s ClickHouse. LangWatch is open source under Apache 2.0. The Developer plan costs nothing and includes 50k events per month, 14-day data access, and two users. Growth costs €29 a month per core seat and includes 200k events. The trust center lists encryption, access controls, privacy features, and enterprise DPAs.
