LiteLLM is free, open-source software you run on your own infrastructure. You have full control, can customize everything, and pay $0 for the software itself. However, you pay for hosting, DevOps time, monitoring, and maintenance. Best for: teams with existing DevOps who want complete control.
ResultantAI Gateway is a managed service. No servers to maintain, no deployments, no monitoring setup. You get a URL and API key, and it just works. $49/month includes 5M tokens, infrastructure, monitoring, and support. Overage is a simple $3/M tokens. Best for: teams who want to ship fast without DevOps overhead.
While LiteLLM is free software, running it in production has real costs:
Infrastructure: $50-200/month (AWS/GCP compute + load balancer + database)
DevOps setup: 20-40 hours initial setup ($2,000-4,000 one-time at $100/hr)
Ongoing maintenance: 5-10 hours/month ($500-1,000/month)
Monitoring tools: $50-100/month (Datadog, Sentry, etc.)
Security updates: Ongoing time commitment
Total first year: $3,000 setup + $600-1,300/month = $10,200-18,600
Platform: $49/month (includes 5M tokens)
Overage: $3/M tokens (simple, no input/output split)
Setup time: 5 minutes
Maintenance: Zero
Monitoring: Built-in
Total first year: $588 (at 5M tokens/month or less)

✓ You have a DevOps team with spare capacity
✓ You need full control over code and infrastructure
✓ You have specific data residency requirements (e.g., EU-only)
✓ You want to customize routing logic extensively
✓ You already have monitoring/logging infrastructure
✓ You're processing 50M+ tokens/month (economies of scale)
✓ You don't have DevOps resources or time
✓ You want to ship fast without infrastructure work
✓ You process 1-20M tokens/month (sweet spot for $49/mo + $3/M overage)
✓ You want predictable, all-inclusive pricing
✓ You prefer zero maintenance and guaranteed uptime
✓ You're a solo founder, small team, or agency
At what point does self-hosting LiteLLM become cheaper than Gateway?
Year 1: Gateway is cheaper ($588 vs $10,200+) due to setup costs
Year 2+: If ongoing DevOps costs drop to ~$200/month, LiteLLM = $2,400/year
vs Gateway = $588/year. Gateway still wins unless you're at massive scale AND have spare DevOps capacity.
Conclusion: At $49/month with 5M tokens included, Gateway's managed service is more cost-effective than self-hosting LiteLLM for virtually every team. You'd need 50M+ tokens/month and an existing DevOps team to justify the self-hosted approach.
