Helicone

Helicone is an LLMOps platform designed to provide routing, debugging, and analytics tools for applications built on large language models. The software takes the form of a cloud platform that enables developers to monitor requests, manage prompts, set rate limits, and analyze usage data. It is aimed at teams and companies building applications on large language models who need to route traffic, debug issues, and monitor performance.

• Route, debug, and analyze applications built on large language models
• Monitor requests and usage data with dashboards and user analytics
• Manage prompts, test with datasets, and use a playground
• Set rate limits, automatic fallbacks, and alerts
• Utilize Helicone Query Language for querying data
• Support for caching responses and gateway features
• Data export capabilities and webhooks

Pros

• Strong infrastructure for monitoring and routing large language model requests across multiple providers
• Extensive feature set for growing and scaling teams, including prompt testing, custom properties, and alerts
• Flexible integration options that fit into various development workflows with minimal setup
• Comprehensive tier options ranging from a free hobby tier to custom enterprise deployments

Cons

• Hobby plan is limited to 10,000 free requests per month, 1 GB of storage, and 1 seat
• Data retention limits apply based on the chosen tier, starting at 7 days for the free plan
• Higher tiers require usage-based pricing on top of the monthly subscription fee
• Enterprise deployment and custom MSA require direct contact with sales

Helicone fits developers, growing teams, and scaling companies building applications on large language models who need centralized monitoring, routing, and prompt management. It is a poor fit for projects that do not use large language models or teams looking for an entirely on-premise solution without opting for the custom Enterprise tier.

Helicone offers a freemium model with a free tier and paid plans above it. The Hobby plan is free and includes 10,000 free requests, 1 GB of storage, 1 seat, and 1 organization. The Pro plan costs $79 per month for growing teams, offering unlimited seats, alerts and reports, and the Helicone Query Language, subject to usage-based pricing. The Team plan costs $799 per month for scaling companies, offering 5 organizations, SOC-2 and HIPAA compliance, and a dedicated Slack channel, subject to usage-based pricing. The Enterprise plan is custom-built and requires contacting sales for pricing, featuring custom MSAs, SAML SSO, and on-prem deployment. Discounts are available for startups, non-profits, open-source companies, and students.

Helicone differentiates itself from alternative monitoring and observability platforms by focusing heavily on provider flexibility, gateway features, and a 1-line integration designed for scaling teams. Compared to alternatives like LangSmith, Braintrust, Arize AI, and Langfuse, Helicone emphasizes prompt and gateway features alongside usage tracking.
