# Apertis vs OpenRouter: choose the operating model, not a logo list

Compare a governed Apertis workspace with OpenRouter's multi-provider routing marketplace by control surface, evidence trail, and the next action to take.

Canonical: https://apertis.ai/compare/openrouter

## Decision intent

You want one compatible API across many models and need to decide whether marketplace-style routing or a governed workspace better matches the workload.

## Decision table

| Question | Apertis | OpenRouter |
| --- | --- | --- |
| Control boundary | **Virtual keys, model policy, quota, and Activity records share one workspace context.** | Budgets, routing controls, and management keys are documented platform features. |
| Upstream keys | **Apertis holds the upstream provider credentials; your team issues bounded workspace tokens, each with its own quota.** | One OpenRouter key authenticates the request and OpenRouter reaches the providers; their pricing page also lists bring-your-own-key allowances. |
| Routing decision | **Channel selection follows declared policy — user group, model availability, and channel priority.** | Their quickstart states fallbacks are handled automatically and the most cost-effective option is picked per request. |
| Verify before migration | **Run one workload and match the response to its Activity record.** | Review the current pricing, routing, and provider documentation for the chosen model. |
| Spend and limits | Quota is enforced per token, and every call lands in the workspace Activity record. | **Their pricing page lists budgets and spend controls, activity logs with export, and rate limits that differ by plan.** |
| Primary job | Operate model access, keys, policy, and usage in one governed workspace. | Reach and route across a broad provider marketplace through one API. |
| Model decision | Live model pages connect model facts to a backend-validated first request. | Model pages expose current provider and pricing options for selection. |

Bold follows the full comparison’s strongest-fit verdict. An unmarked row makes no additional ranking between these two platforms.

## Fit, not winner

### Choose Apertis when

Choose Apertis when the decision depends on bounded keys, explicit model policy, workspace usage records, and a managed path from model evaluation to first call.

### Choose OpenRouter when

Choose OpenRouter when its current provider marketplace, model routing, and published platform controls are the direct fit. Confirm current fees, limits, and provider behavior on OpenRouter before committing.

## Migration path

1. **Inventory the client contract** — Capture the base URL, model IDs, streaming behavior, supported parameters, retries, and any routing preferences currently in use.
2. **Map models using live records** — Open the current model pages on both services. Do not translate IDs or provider behavior from memory.
3. **Move one non-critical workload** — Change the compatible endpoint and key for a bounded workload, then compare the response and usage record.
4. **Retire old keys only after evidence** — Keep rollback credentials controlled until the new path has passed functional, cost, and observability checks.
