In their own words
Braintrust
Braintrust is an observability platform for teams running AI agents in production. It lets teams inspect agent traces and tool calls while tracking latency, cost, and quality in real time. Users can evaluate datasets, compare prompts and models, and score outputs with LLMs, code, or human reviewers. Discovery tools surface patterns in production traces to help investigate agent behavior, and the Loop agent can run evaluations, generate test cases, and iterate on prompts autonomously. Braintrust lists native SDKs for Python, TypeScript, Go, Ruby, C#, and more, and its MCP server lets coding agents query logs, run evaluations, and update prompts from an IDE. Security options listed include SSO, RBAC, and hybrid deployment; Braintrust states that it is SOC 2 Type II certified and GDPR and HIPAA compliant. Starter is free, with 1 GB processed data, 10,000 scores, and 14-day retention. Pro costs $249.00 per month; Enterprise pricing is custom.
PromptHelm
PromptHelm is a prompt management platform for engineering teams building LLM features. It supports deploying prompts by environment, keeping version histories, rolling back changes, and testing in a playground. Its multi-provider gateway names OpenAI, Anthropic, Google, and DeepSeek. Teams can track token spending by model and prompt, review usage and cost trends, and set budget alerts. Request monitoring filters by status, model, or prompt and provides request and response details for debugging; analytics cover P50/P95/P99 latency, error rates, and model performance comparisons. SDKs are listed for Node, Python, iOS, Android, Java, and.NET. Plans include a free tier, Pro at $39 a month, and Business at $249 a month; Enterprise pricing is custom and unlisted. New accounts receive an automatic 14-day Pro trial without a credit card. The documentation describes access as invite-only, with private-beta invitations rolling out weekly.
