Respan AI (formerly Keywords AI) is an engineering platform that gives LLM applications enterprise-grade lifecycle management, observability, and reliability—so you can move from prototype to production without surprises.
Respan AI is the rebranded evolution of Keywords AI. All legacy features remain, plus deeper observability and native AI-agent management.
Full-stack traces record every agent step and tool call. Replay any failed session in a sandbox, inspect the Span tree, and push the fix with confidence.
One gateway connects to 500+ models—OpenAI, Anthropic, Google, open-source, or your own—with smart routing, load-balancing, and BYOK.
Turn on online or offline evals, pick LLM-as-a-judge, custom Python, or human review, and get automatic quality scores for prompts, models, or configs.
Yes—freemium plan with free credits and a sandbox. Enterprise tiers and pricing are available on request.
ISO 27001, SOC 2, GDPR, and HIPAA audited—complete audit trails and data governance included.
80+ out-of-the-box metrics (cost, tokens, latency, drift) plus custom dashboards. Alerts fire through Slack, email, SMS, or webhooks and can auto-curate datasets for you.
Arize AI is a lifecycle observability and evaluation platform for large language models (LLMs) and agents. It helps AI engineering teams monitor, evaluate, and optimize model performance to ensure application reliability and business impact.
Helicone AI is an open-source AI gateway and LLM observability platform that helps developers monitor, optimize, and deploy AI applications powered by large language models, improving reliability and cost efficiency.
