Platform for evaluating, guarding, and monitoring LLM and agent applications across the deployment lifecycle. Anchored by research-backed evaluator models — Lynx (hallucination detection), GLIDER (LLM judge), and Percival (agent-trace debugger). Offers a self-serve API with free credits, usage-based pricing, and enterprise plans.

Capabilities 3

What it actually does — grouped by capability family.

  • LLM evaluation (primary capability)
  • Guardrails (primary capability)
  • LLM observability (secondary capability)

Pros & cons

  • Research-backed Lynx, GLIDER, and Percival models
  • Covers hallucination, judging, and agent-trace debug
  • Self-serve API with free credits
  • Guardrails + monitoring across the lifecycle
  • Cloud-only; no self-host
  • Usage-based pricing can be opaque at scale
  • Smaller OSS footprint than open eval tools

    Exploding Gradients

    Evaluation toolkit for RAG and LLM applications.

    Open-source (Apache-2.0) Python framework for evaluating retrieval-augmented generation and LLM apps. Provides reference-free metrics — faithfulness, answer relevancy, context precision/recall — plus knowledge-graph-based synthetic test generation. Integrates with LangChain, LlamaIndex, and CI pipelines.

    LLM eval CLI with rubric scoring and golden sets.

    YAML-driven eval harness. Pair a prompt with a goldset, define rubrics, run across multiple models in CI. Strong for catching prompt regressions before they hit production.
