How Solidway differs from Bifrost and LiteLLM
All three are LLM gateways, but they answer a different question: what should the gateway do to a request on its way through? Everything below is what we could verify against each project itself.
When Solidway is the wrong choice
We would rather you pick the right tool. Solidway is not the answer if any of these apply.
- You want to call Claude through the OpenAI SDK, or any model through another vendor’s SDK. Solidway does not translate between dialects; Bifrost and LiteLLM do.
- You need ready-made adapters across a long list of providers. LiteLLM covers more providers than we do.
- You want to change gateway behaviour in Python, in the same language as the rest of your stack. LiteLLM fits that better.
Design trade-offs
| Dimension | Solidway | Bifrost | LiteLLM |
|---|---|---|---|
| What the gateway does to a request | Forwards it unchanged | Converts to a unified schema, then to the provider format | Converts to a unified schema, then to the provider format |
| Implementation language | Rust | Go | Python |
| Calling vendor A with vendor B’s SDK | Not supported, by design | Supported | Supported |
| Adding a provider | Configuration change | Adapter code | Adapter code |
| Failover | Built in | Built in | Built in |
| Load balancing | Built in | Built in; adaptive balancing is a commercial-edition feature | Built in, with several published strategies |
| Circuit breaking | Built in | A commercial-edition feature | Deployment cooldown and retry budgets |
| Deployment shape | One static binary | One static binary or a container | A Python service or a container |
Where a capability is offered only in a commercial edition, the table says so rather than marking it absent.
Three different constraints
Solidway
Keeps the provider’s own contract intact. The gateway is responsible for routing and health, and for nothing else on the payload. New model parameters work without a gateway release, and nothing in the path can alter what the provider sees.
Bifrost
Puts a unified schema in the middle so that one SDK can reach many providers, and wraps governance, budgets and a plugin system around it. Circuit breaking and adaptive balancing belong to its commercial edition.
LiteLLM
Prioritises breadth: a long provider list, many API surfaces, and a set of published routing strategies. The gateway is written in Python, so it can be extended in place.
