HiWay2LLM vs LiteLLM

LiteLLM and HiWay2LLM both sit between your app and the LLM providers, both speak the OpenAI API, and both claim to unify access to dozens of models behind one interface. If you stop reading there, they sound interchangeable. They are not.

LiteLLM is an open-source Python library and proxy server maintained by BerriAI. You install it, you run it, you operate it. It's the most battle-tested OSS LLM router in existence, with a community-driven catalog of 100+ providers and a healthy GitHub. It also ships as a managed SaaS called LiteLLM Cloud. HiWay2LLM is a managed BYOK router with a different routing philosophy (complexity-based, not fallback-based), EU-hosted by default, and a flat monthly fee.

The real question isn't "which one is better." It's "do you want to run a service, or pay someone to run it for you — and if you pay, which routing model do you actually want."

Quick decision

• Have an infra team with capacity and want zero external dependency? Self-host LiteLLM. It's free, OSS, and you own every moving part. This is the right answer for a lot of teams.
• Want the routing layer but not the ops? HiWay is the managed option with smart routing, EU hosting, DPA on request, and a flat fee.
• Currently on LiteLLM Cloud? You're already paying for managed. The differences then are: HiWay routes by request complexity (LiteLLM by provider fallback), HiWay is EU-hosted (LiteLLM Cloud is US-based), and HiWay's pricing is flat, not metered.
• Need a weird provider or self-hosted model (vLLM, Ollama, TGI, Bedrock, Vertex with custom endpoints)? LiteLLM's provider catalog is unmatched — 100+ integrations. HiWay covers ~60+ models from the mainstream providers.
• In the EU or selling to EU customers? HiWay is operated from France and hosted on OVH. Self-hosted LiteLLM gives you full residency control; LiteLLM Cloud is US.

Pricing

LiteLLM the OSS proxy costs you zero in software. It costs you whatever running a production-grade service costs: a VM or container to host the proxy, a Redis or Postgres for the routing/key store, monitoring, on-call rotation, security patches, and the engineering time to configure and maintain it. For a small team that's a few hundred euros a month in infra and a few days of setup, then a handful of hours of maintenance per quarter. For a larger org running it HA across regions, significantly more.

LiteLLM Cloud is their managed tier. Based on their public pricing as of 2026-04-22, it's a paid SaaS with per-request metering and volume tiers. Check their site for current numbers — they've moved over time.

HiWay is flat, with BYOK on top: inference is billed directly by the provider on your card at wholesale rates, 0% markup from HiWay. The routing layer is priced per plan:

The honest framing: if you self-host LiteLLM, the "price" you pay is operational load — a VM, a DB, monitoring, and the engineer-hours to maintain it all. If that load starts to cost you more than a few hours a month, managed is usually cheaper once you count everything. And on HiWay specifically, smart routing (auto-downgrade simple requests to cheaper models — 40-85% savings on a typical mix) overtakes the $15/mo Build subscription within hours of real use, at any scale.

Feature-by-feature

When to pick which

Migration

If you're running LiteLLM as a proxy today, your app is already pointed at an OpenAI-compatible base URL. Switching to HiWay is a URL and key swap. The request shape is identical.

from openai import OpenAI

# LiteLLM proxy running locally or on your infra
client = OpenAI(
  base_url="http://localhost:4000",
  api_key="sk-1234",  # your LiteLLM virtual key
)

response = client.chat.completions.create(
  model="claude-3-5-sonnet",
  messages=[{"role": "user", "content": "Hello"}],
)

from openai import OpenAI

client = OpenAI(
  base_url="https://app.hiway2llm.com/v1",
  api_key="hw_live_...",
)

response = client.chat.completions.create(
  model="auto",  # let the router pick
  messages=[{"role": "user", "content": "Hello"}],
)

One-time setup: drop your provider keys into Settings → Providers in the HiWay dashboard. If you want to keep pinning a specific model instead of letting the router pick, pass the model name (claude-3-5-sonnet, gpt-4o, etc.) instead of "auto".

Self-hosting vs managed — what you actually sign up for

The defining choice between LiteLLM and HiWay is not about features. It's about what you want to operate.

Self-hosting LiteLLM means you own the proxy. You deploy it (Docker, Kubernetes, a VM). You put a Redis and/or Postgres behind it for virtual-key management and spend tracking. You monitor it (Prometheus, Grafana, or whatever stack you use). You upgrade it on each release. You debug it when a provider changes their API. You make sure it's HA if your production cares about availability. This is not particularly hard work — LiteLLM's docs are solid and the community is helpful — but it is work, and someone on your team owns the pager.

HiWay is managed. We run the proxy, we monitor it, we ship updates, we handle the provider-API churn, we keep the EU region up. You get a dashboard, an API key, and a support channel. The trade-off: you depend on us. If HiWay goes down, your proxy goes down until we fix it. (Our SLO is 99.9% and our status page is public, but it's not zero risk.)

LiteLLM Cloud sits in the middle: managed, but with LiteLLM's routing philosophy and US hosting. If you're considering LiteLLM Cloud, the comparison with HiWay is narrower — it's really about routing approach and data residency, not self-host vs managed.

Neither answer is universally correct. A team of three shipping an MVP doesn't need to run a proxy. A 200-engineer org with a platform team that already runs 40 microservices probably doesn't want another SaaS dependency. Pick based on your actual constraints.

Data & compliance

Self-hosted LiteLLM puts you in complete control of the data path. The prompts never leave your infrastructure; the logs live where you put them; residency is whatever your VPC is. This is the strongest compliance story possible — but you own it end-to-end. If you log prompts to CloudWatch and someone leaks the bucket, that's on you.

LiteLLM Cloud is operated by BerriAI from the US. Check their current DPA and sub-processor list directly if you're in a regulated industry.

HiWay is operated by Mytm-Group from France, hosted on OVH servers in the EU. Zero prompt logging by default — prompts transit in-memory, nothing is persisted. DPA on request, published sub-processor list, GDPR-aligned data handling. For EU-regulated industries (health, finance, legal) the EU-native path is usually the shortest road through the compliance review.

FAQ

Bottom line

LiteLLM is an excellent piece of open-source software — if you want zero vendor dependency and have the team to run it, it's probably the best OSS router on the market. HiWay is the managed alternative for teams who want the routing intelligence and EU hosting without operating a proxy themselves. There's no winner in the abstract; there's a right answer for your constraints.

If you're currently spending engineer-hours running LiteLLM and that's starting to feel like drag, or if you're on LiteLLM Cloud and EU hosting matters, try HiWay's free tier and see how it feels. No credit card, 2,500 requests/month, keep your keys.
