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
Portkey - Pros & Cons
Pros
- ✓Provider-agnostic routing with declarative configs that an SRE can change without app deploys
- ✓Strong governance primitives (virtual keys, budgets, RBAC) that internal gateways usually skip
- ✓Built-in guardrails and observability remove the need for a separate vendor for each
- ✓Self-hosted and BYOC options make it viable for regulated and air-gapped deployments
Cons
- ✗Pricing page is JS-rendered and dollar amounts must be confirmed manually on site
- ✗Adds a network hop and latency overhead — small but non-zero next to direct provider calls
- ✗Overkill for single-provider single-app teams who do not need governance
- ✗Some advanced features (Agents, BYOC) require Enterprise contracts
