DeepEval is an Apache-2.0 Python framework for evaluating LLM apps, RAG systems, agents, MCP workflows, and safety behavior with repeatable test cases. It works locally and in CI/CD, then connects to Confident AI for hosted reports, observability, red teaming, and governance when teams need shared evidence instead of ad-hoc prompt reviews and manual QA.
Open-source core (Apache-2.0) with $0 local Pytest evaluations. Confident AI Cloud Free includes 2 seats, 5 test runs/wk, and 5 GB-mo trace data. Starter is $99-$200/mo for automated CI/CD testing ($1/GB-mo trace overage). Pro/Team is $499-$2,000/mo with 75 GB trace data, Git prompt versioning, RBAC, and SOC 2 Type II. Enterprise offers custom pricing for VPC/on-premise deployment, DeepTeam AI Red Teaming, production Guardrails, HIPAA compliance, and 24/7 SLA.Review →
Promptfoo is an OpenAI-owned open-source toolkit for evaluating, red-teaming and securing LLM applications. It supports config-driven prompt/model tests, CI regression gates, red-team scans, guardrails, model security workflows, MCP Proxy, code scanning and evaluations across prompts, agents and RAG pipelines.
promptfoo is open-source and free to run locally under the MIT license for unlimited evaluations and up to 10,000 red-team probes per month. Enterprise SaaS and On-Premise editions feature custom pricing with team collaboration, RBAC, and dedicated security monitoring.Review →
TruLens is an open-source framework for evaluating and tracking LLM experiments with feedback functions, RAG triad metrics (answer relevance, context relevance, groundedness), and Honest/Harmless/Helpful evaluations. Features a unified Metric API for systematic evaluation of RAG pipelines and AI agents. 3,200+ GitHub stars, MIT licensed. Snowflake partnership adds enterprise integration. Supports LangChain, LlamaIndex, and custom LLM applications.
100% free and open source under the MIT license ($0 software license via pip install trulens). Includes local SQLite/PostgreSQL logging and a built-in Streamlit dashboard. Enterprise deployment integrates with Snowflake AI Observability and Snowflake Cortex, incurring only standard Snowflake compute credits and storage fees with no proprietary TruLens licensing charge.Review →
Braintrust is an AI observability and evaluation platform for tracing LLM applications, building datasets, running prompt/model experiments, scoring outputs and turning production feedback into regression tests. It fits teams that need repeatable quality gates for AI releases rather than one-off prompt demos.
Starter plan is free with unlimited users, $10 in credits, 1 GB data ingestion, 10,000 scores, and 14-day retention. Pro plan is $249/month including $249 in credits, 5 GB data ingestion, 50,000 scores, 30-day retention, and RBAC ($3/GB data and $1.50/1k score overages). Enterprise plan offers custom data retention, VPC/on-premise self-hosted options, and dedicated SLAs.Review →
