💡 Pro tip: Start with the free tier to test if TruLens fits your workflow before upgrading to a paid plan.
per month
Don't overpay for features you won't use. Here's our recommendation based on your use case:
Most AI tools, including many in the testing & quality category, offer special pricing for students, teachers, and educational institutions. These discounts typically range from 20-50% off regular pricing.
• Students: Verify your student status with a .edu email or Student ID
• Teachers: Faculty and staff often qualify for education pricing
• Institutions: Schools can request volume discounts for classroom use
Most SaaS and AI tools tend to offer their best deals around these windows. While we can't guarantee TruLens runs promotions during all of these, they're worth watching:
The biggest discount window across the SaaS industry — many tools offer their best annual deals here
Holiday promotions and year-end deals are common as companies push to close out Q4
Tools targeting students and educators often run promotions during this window
Signing up for TruLens's email list is the best way to catch promotions as they happen
💡 Pro tip: If you're not in a rush, Black Friday and end-of-year tend to be the safest bets for SaaS discounts across the board.

Open-source AI observability and evaluation platform built on OpenTelemetry for tracing, debugging, and monitoring LLM applications and AI agents in production.
Free tier available
✓ Free plan available
TruLens can evaluate a wide range of LLM-powered applications including AI agents, retrieval-augmented generation (RAG) pipelines, summarization systems, and custom agentic workflows. It is designed to assess critical components of an app's execution flow such as retrieved context quality, tool call accuracy, planning steps, and final output quality. This makes it versatile enough for both simple chatbot evaluations and complex multi-step agent assessments.
TruLens uses feedback functions—automated evaluation routines—to measure metrics like groundedness and context relevance. Groundedness checks whether the LLM's generated response is supported by the retrieved source material, flagging hallucinated or unsupported claims. Context relevance evaluates whether the retrieved documents are actually pertinent to the user's query. These metrics are computed using LLM-based evaluators or custom scoring functions that you can configure to match your quality standards.
TruLens now supports OpenTelemetry (OTel), an open standard for distributed tracing and observability. This means traces generated by TruLens can be exported to any OTel-compatible backend such as Jaeger, Grafana Tempo, or Datadog. For teams that already have observability infrastructure in place, this eliminates the need for a separate monitoring stack and allows LLM application traces to live alongside traditional service traces for unified debugging and performance analysis.
TruLens is designed to be framework-agnostic and integrates with popular LLM frameworks and providers. It works with applications built using LangChain, LlamaIndex, and custom implementations, and can evaluate outputs from various LLM providers including OpenAI, Anthropic, and open-source models. The instrumentation is lightweight and typically requires only a few lines of code to wrap your existing application for evaluation and tracing.
TruLens provides a leaderboard view where you can compare different versions or configurations of your LLM application across multiple evaluation metrics simultaneously. Each app variant is scored on metrics like groundedness, relevance, coherence, and any custom metrics you define. This allows you to objectively identify which combination of prompts, models, retrieval strategies, or hyperparameters produces the best results, replacing manual review with data-driven decision-making at scale.
