Workweave released Router, a tool that performs smart model routing inside Claude, Codex, and Cursor. The project appeared on Hacker News where the thread reached 54 points and 37 comments.
The GitHub repository is available at https://github.com/workweave/router.
What It Is
Router sits between the user prompt and the connected models. It evaluates the request and forwards it to the model judged most suitable among the available options in Claude, Codex, or Cursor.
No separate API layer is required. The routing logic runs directly in the supported editors and chat interfaces.
How to Try It
Install the package from the repository and configure the supported clients. Users point Claude, Codex, or Cursor at the local Router endpoint instead of the direct model URLs.
The setup uses standard configuration files already present in those tools. No additional servers or cloud accounts are needed beyond the original model credentials.
Pros and Cons
- Works inside existing Claude, Codex, and Cursor sessions without switching apps.
- Reduces manual model selection for each prompt.
Runs locally with the user's existing API keys.
Limited to the three named interfaces at launch.
Routing decisions depend on the heuristics shipped in the current release.
Community feedback on Hacker News noted the need for more transparent routing logs.
Alternatives and Comparisons
Other routing approaches require external proxies or separate orchestration layers. Router differs by embedding directly in the three listed clients.
| Feature | Workweave Router | External proxy tools | Manual switching |
|---|---|---|---|
| Integration | Native in Claude/Cursor | Separate process | None |
| Setup steps | Config file edit | New service install | None |
| Model visibility | Direct | Proxied | Direct |
Who Should Use This
Developers who already work primarily in Claude, Codex, or Cursor and want automatic model selection will see the clearest benefit. Teams that prefer full control over every model call or require detailed routing audit logs should continue with manual selection or external proxies.
Bottom Line / Verdict
Router fills a narrow but practical gap by moving model routing inside the three most common interfaces rather than adding another layer outside them. Early Hacker News discussion shows interest in seeing how the heuristics perform on varied workloads.
The project remains an early-stage Show HN release. Its value will depend on how accurately the routing logic matches user expectations across different prompt types.
