ResultantAI Gateway vs Portkey: Which is Better?

Bottom line: ResultantAI Gateway wins at every volume level. At $49/mo with 5M tokens included and just $3/M overage, the Gateway is cheaper than Portkey's $49 platform fee + separate provider costs at every usage tier. Choose Portkey only if you need advanced observability features like prompt versioning and A/B testing.

Pricing Comparison

ResultantAI Gateway Pricing

The Gateway charges $49/month with 5 million tokens included. If you go over, it's a flat $3 per million extra tokens. No complicated input vs. output rates. Smart routing automatically picks cheaper AI models when possible, stretching your budget further. And budget caps mean you'll never wake up to a surprise bill.

Portkey Pricing

Portkey charges $49/month for the platform, but you still pay OpenAI, Anthropic, or Google separately for every AI request. Those provider bills add up fast — typically $2.50+ per million tokens on top of the $49. There's no automatic cost optimization, so you pay full price for every request, even simple ones.

Real-World Cost Comparison

Monthly Usage Gateway Cost Portkey Cost Winner
1M tokens $49 $49 + $2.50 = $51.50 Gateway
3M tokens $49 $49 + $7.50 = $56.50 Gateway
5M tokens $49 $49 + $12.50 = $61.50 Gateway
10M tokens $49 + $15 = $64 $49 + $25 = $74 Gateway
20M tokens $49 + $45 = $94 $49 + $50 = $99 Gateway

Verdict: The Gateway wins at every volume level. Same $49 base price as Portkey, but with 5M tokens included and $3/M overage vs paying providers separately. The math never favors Portkey on price alone.

Can You Use Both?

No -- both sit between your app and AI providers, so you can only use one at a time. You must choose one. However, you could use the Gateway for production traffic and Portkey for development/testing if needed.
