In their own words
Arklex
Arklex evaluates AI agents with simulated multi-turn conversations, helping teams check how agents respond across scenarios. Its open-source ArkSim framework creates synthetic users with different profiles, goals, and knowledge levels, then assesses responses using built-in measures for helpfulness, coherence, relevance, faithfulness, verbosity, goal completion, and agent behavior failures. Teams can add reusable custom metrics in plain language, review and dispute judge scores, and add human assessments while preserving the original scores. Calibration tracks agreement by metric. Reusable scenarios support comparisons between agent versions and regression checks; ArkSim can also act as a CI quality gate, returning a non-zero result when thresholds are not met. Agents connect through Python classes, Chat Completions HTTP endpoints, or the A2A protocol. The hosted Arklex Platform adds a UI for scenarios, conversations, and scoring. ArkSim is free and open source under Apache-2.0. Its documentation requires Python 3.10 through 3.13 and an API key from OpenAI, Anthropic, or Google; OpenAI is the default provider.
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.
