FAQ

What do I get with the free plan?
The free Hobby plan includes 10,000 free requests per month, 1 GB storage, 1 seat, and 1 organization. It also provides basic monitoring features like requests, sessions, and user analytics, with 7-day data retention and 10 logs/min ingestion.
How is Helicone's usage-based pricing calculated?
Usage-based pricing applies to requests, tokens, and storage beyond the free allowances. For example, the Pro plan includes 10K free requests per month and charges for additional usage. You can estimate costs using the pricing calculator on the website.
What happens if I exceed my limits?
If you exceed the limits of your current plan, you may be charged based on usage or prompted to upgrade. The free plan has a hard cap at 10,000 requests per month; exceeding it likely requires moving to a paid plan.
Can I switch plans or cancel anytime?
Yes, plans are flexible. You can upgrade or downgrade at any time. All paid plans offer a 7-day free trial, and you can cancel without penalty.
Does Helicone work with my LLM provider?
Yes, Helicone is designed to work with any LLM provider through its gateway and one-line integration. It supports common providers like OpenAI, Anthropic, and others.
Is there a plan for teams or enterprise use?
Yes, the Team plan ($799/month) includes 5 organizations, SOC-2 and HIPAA compliance, dedicated Slack channel, and higher limits. Enterprise plans offer custom MSAs, SAML SSO, on-prem deployment, and dedicated support.
Do you offer discounts for startups, students, or open source projects?
Yes, Helicone offers a 50% discount for the first year for startups under 2 years old and under $5M in funding. Non-profits receive discounts based on organization size. Open-source companies get a $100 credit, and students get free access.
