Helicone vs OpenRouter
Both are alternatives to Portkey. Here's how they stack up — verified facts, no spin.
Also searched as OpenRouter vs Helicone — same comparison, one verdict.
Helicone
Apache-2.0 gateway in Rust, with observability built in rather than bolted on.
Helicone is an open-source AI gateway written in Rust, with logging, caching and cost tracking built into the routing layer rather than added alongside it — which is the practical difference from LiteLLM, where observability is thin and usually paired with something else. It is Apache-2.0 throughout, self-hostable, and also offered as a hosted service with a free tier. For teams who want one component instead of two, it is the tidier answer.
OpenRouter
One key, hundreds of models, nothing to run — the honest hosted pick.
OpenRouter is a hosted router: a single API key and one OpenAI-compatible endpoint in front of hundreds of models across providers, with automatic fallback and a unified bill. There is nothing to deploy and no subscription — you pay per token with a small margin on top of provider rates. If what you actually wanted was to stop juggling five provider accounts, this solves it in an afternoon and is frequently the right answer even for teams who could self-host.
Side by side
| Helicone | OpenRouter | |
|---|---|---|
| Sovereignty Score | 88 | 32 |
| Open source | Yes | No |
| Self-hostable | Yes | No |
| Local-first | Yes | No |
| License | Apache-2.0 | Proprietary (hosted service) |
| Pricing | Free and self-hostable under Apache-2.0. The hosted service has a free tier of roughly 10,000 requests per month, with paid plans starting around $79/month. | No subscription — pay-as-you-go per token at provider rates plus a small margin. Some free models are available. |
Helicone edges it on the Sovereignty Score, but the right pick depends on the trade-offs below.
Helicone
Strengths
- +Apache-2.0 with no enterprise-directory carve-out
- +Routing and observability in one component — less to assemble
- +Written in Rust; low latency overhead for a proxy
- +Hosted option with a real free tier if you would rather not run it
Trade-offs
- −Smaller project and community than LiteLLM (about 6k stars)
- −Fewer providers supported than LiteLLM's 100+
- −The hosted tier means prompts transit a third party — the thing self-hosting avoided
- −Less mature budget and virtual-key tooling than LiteLLM
OpenRouter
Strengths
- +Zero operations: one key, one endpoint, hundreds of models
- +No monthly fee — you pay only for tokens used
- +Unified billing across providers, with automatic fallback
- +The fastest way to test many models without opening accounts everywhere
Trade-offs
- −Hosted and proprietary: every prompt transits OpenRouter
- −A margin on token spend rather than provider cost
- −No self-hosting path at all
- −Score of 32 reflects a closed hosted service — a transparency lens, not a judgement on quality
