ResultantAI Gateway is designed to prevent bill shock and reduce costs. At $49/month with 5M tokens included and $3/M overage, it provides budget caps, spending alerts, and smart routing to cost-effective models (Gemini Flash $0.15/M, Haiku $0.80/M). Primary use case: agencies and builders who need predictable pricing and per-client tracking.
Helicone is designed for monitoring and debugging. It logs every request/response, tracks latency, provides detailed analytics, and helps you understand user behavior. Primary use case: product teams debugging LLM features and optimizing prompt performance.

Includes 5 million tokens (the units AI models use to measure usage). If you go over, it's $3 per million extra. Smart routing automatically picks cheaper AI models for simple tasks, so your budget goes further. Budget caps mean your bill is always predictable.
Pro plan is $50-70/month depending on request volume. Does NOT include tokens -- you pay OpenAI/Anthropic separately. Helicone charges for the observability platform, not the tokens.
Gateway: $49/month with 5M tokens included, $3/M overage
Helicone: ~$60/month + you pay OpenAI/Anthropic separately (unlimited billing)
Gateway wins on price at every level: lower base cost ($49 vs ~$60), plus tokens are included. Helicone doesn't include budget caps -- if your app goes viral overnight, you're on the hook for the provider's full bill. Gateway provides budget protection and automatic cost savings through smart routing.
✓ Your #1 priority is preventing bill shock
✓ You need hard spending caps and budget alerts
✓ You want predictable, all-inclusive pricing ($49/mo with 5M tokens)
✓ You're an agency needing per-client billing
✓ You want intelligent routing to reduce costs
✓ Your #1 priority is observability and debugging
✓ You need detailed request/response logs
✓ You want latency analytics (P50/P95/P99)
✓ You need user session tracking
✓ You have separate budget management already
Yes! Many teams use Gateway for routing + cost control, then forward logs to Helicone for observability. Route requests through Gateway (gets you failover, budget caps, intelligent routing), and use Helicone's SDK to log request metadata. This gives you the best of both worlds: cost protection + detailed analytics.
Total cost: $49 (Gateway) + $60 (Helicone) = $109/month for comprehensive cost + observability coverage. Worth it for teams running production LLM features at scale.
