Klu
Generative AI app platform — design, deploy, and optimize LLM-enabled applications with collaborative prompt management, experiments, and evals.
Overview
Klu.ai: GenAI Application Platform
Klu is a generative AI application platform that simplifies the design, deployment, and optimization of AI-enabled applications. AI Teams use Klu to collaboratively iterate on prompts, evaluate performance against test datasets, run experiments comparing models and configurations, and monitor production behavior — all in one platform.
Sits in the same space as Braintrust, Langfuse, and Athina with a focus on collaborative team workflows for shipping LLM features.
Key Features
- Collaborative prompt management with versioning
- Experiments — compare prompts, models, and configurations side-by-side
- Evals against datasets with code, LLM, or human scoring
- Production logging and observability
- Model-agnostic — supports OpenAI, Anthropic, Google, open models, custom
Ideal Use Case
Product and engineering teams shipping LLM-powered features who want a unified surface for prompt iteration, evals, and observability rather than stitching together multiple tools. Particularly strong for teams where non-engineers (PMs, designers) participate in prompt iteration.
Why Use Klu
Most LLMOps tools lean either developer-first (Langfuse, OSS-heavy) or eval-first (Braintrust). Klu's wedge is collaborative team workflows — prompts as a shared, versioned artifact PMs and engineers iterate on together.
FAQ
Q: How is Klu different from Braintrust? A: Both target LLM evals + observability. Klu emphasizes collaborative prompt management and team workflows; Braintrust leans more eval-experiment-first.
Q: What models does Klu support? A: OpenAI, Anthropic, Google, Mistral, open-source via Ollama, and any OpenAI-compatible endpoint.
Q: Is there a free tier? A: Yes, with paid plans for higher volume and team features.
tl;dr
Collaborative GenAI app platform. Prompts, evals, experiments, observability — for teams shipping LLM features together.
