Helicone

What is Helicone?

LLM usage routed, debugged and analysed.

Who is Helicone best for?

Helicone is best for developers running LLM apps in production who need request logs, cost tracking and a gateway.

• Teams shipping LLM features

  Every request, response time and cost is logged, so you can trace sessions and users and find slow or failing calls.

• Apps on several model providers

  The gateway routes calls to OpenAI, Anthropic, Azure, OpenRouter and others, with caching, rate limits and automatic fallbacks.

• Early-stage startups

  The free plan covers 10,000 requests a month, and young startups can apply for half off the first paid year.

• Regulated products

  The Team plan adds SOC-2 and HIPAA compliance, and Enterprise can run on your own servers.

How much does Helicone cost?

Helicone's Hobby plan is free with 10,000 requests a month, and its paid plans cost $79 a month for Pro or $799 a month for Team, plus usage-based fees for extra requests and storage.

Pro and Team include 10,000 requests and 1 GB of storage; after that, requests cost $0.0007 each, falling in tiers to $0.00002 above 2.5 million, and storage costs $3.25 per GB for the first 30 GB, falling to $0.50 per GB above 450 GB. Enterprise is priced on request and adds SAML SSO, on-prem deployment and a custom MSA. Startups under 2 years old with under $5M in funding can get 50% off the first year, students and educators are usually free, and non-profits and open-source companies can ask for discounts or credits.
