💡 Our Take
Choose AI Gateway if you need full governance — permissions, rate limits, guardrails, and MCP control — integrated into a data platform. Choose Helicone if your primary need is lightweight LLM observability and cost tracking with a fast open-source option and a generous free tier, and you do not require deep access control or MCP governance.
AI Gateway - Pros & Cons
Pros
- ✓Native integration with Unity Catalog means permissions, audit logs, and lineage work identically to the rest of your Databricks data assets without extra IAM plumbing
- ✓OpenAI-compatible client interface allows existing application code to point at AI Gateway endpoints with minimal refactoring
- ✓Governs three distinct asset types (LLM endpoints, MCP servers, coding agents) in a single pane of glass — rare across the 870+ tools in our directory
- ✓No charges during Beta (confirmed on docs as of April 15, 2026), letting teams pilot full governance workflows before committing to enterprise pricing
- ✓Supports major coding agents including Cursor, Claude Code, Gemini CLI, and Codex CLI, covering the dominant agent tools developers use in 2026
- ✓Inference tables land as Delta tables in Unity Catalog, making audit and monitoring queries trivially accessible via SQL or notebooks
Cons
- ✗Only available inside the Databricks platform — teams not already on Databricks cannot adopt AI Gateway as a standalone product
- ✗Currently in Beta, meaning feature set, APIs, and limits may shift before GA and enterprise SLAs may not apply
- ✗Two parallel versions exist (new AI Gateway in left nav vs. previous AI Gateway for serving endpoints), which creates documentation and migration ambiguity
- ✗Custom MCP server hosting requires packaging as a Databricks App, adding a layer of platform-specific deployment knowledge
- ✗Pricing is opaque enterprise-contract based with no public tier breakdown, making TCO comparisons against standalone gateways difficult
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
