LiteLLM - Pros & Cons
Pros
- ✓Provides a unified API proxy for 100+ LLM providers, reducing the need to maintain separate provider integrations in application code.
- ✓Uses an OpenAI-compatible interface, which can make it easier for teams already using OpenAI-style APIs to add or switch providers.
- ✓Includes production-oriented routing capabilities such as load balancing and automatic failovers.
- ✓Supports spend tracking and budget controls, which are important for managing unpredictable LLM usage costs.
- ✓Open-source positioning gives technical teams more transparency and deployment flexibility than a purely closed hosted gateway.
- ✓Fits centralized AI infrastructure use cases where multiple applications or teams need consistent provider access and governance.
Cons
- ✗Adding an AI gateway introduces another infrastructure component that must be deployed, configured, monitored, and kept reliable.
- ✗Teams using only one LLM provider may not benefit enough from routing, failover, and multi-provider abstraction to justify the extra layer.
- ✗Enterprise pricing is custom rather than transparent in the supplied metadata, so larger teams need a sales process to understand total cost.
- ✗The scraped website content provided here is hard-trimmed and does not include detailed public plan limits, SLA terms, or enterprise feature boundaries.
- ✗LiteLLM focuses on gateway and proxy infrastructure; teams looking primarily for prompt collaboration, evaluation workflows, or analytics dashboards may need complementary tools.
Helicone - Pros & Cons
Pros
- ✓5-minute proxy integration captures full traces, cost, and latency across 20+ providers
- ✓Real AI gateway features (caching, retries, fallback, key vault) replace a custom proxy
- ✓MIT-licensed and self-hostable on Postgres + ClickHouse — passes regulated procurement
Cons
- ✗Proxy mode adds a network hop unless self-hosted in your own region
- ✗Prompt experiment UX is less mature than dedicated eval platforms like Braintrust
- ✗Self-hosting requires running ClickHouse, which is an extra ops surface
