Weave Router 2.0
A subscription-aware AI coding assistant router that routes coding requests across different vendors' subscription boundaries, automatically dispatching requests to the most cost-effective model with remaining quota. It employs a task-complexity classifier and a cost-aware switching mechanism to optimize the balance between cost and output quality.

Weave Router 2.0 topped Product Hunt, receiving 127 upvotes and ranking first.
Weave Router 2.0 is a Subscription Aware coding assistant router that automatically dispatches coding requests to the most cost-effective model capable of completing the task.
Weave Router 2.0 can break down subscription barriers between different vendors, enabling calls to Claude models within Codex and GPT models within Claude Code, routing to services with remaining quota based on existing paid plans.
The vendor officially claims that Weave Router 2.0 performs on par with GPT-6 Astra on the Terminal-Bench 4.0 and SWE-Atlas benchmarks, at half the cost and twice the speed.
The performance figures for Weave Router 2.0 come solely from vendor-side promotional claims and have not yet been corroborated by independent third-party evaluations.
Weave Router 2.0's routing decisions are driven by two mechanisms: a task complexity classifier and cache-aware switching.
The cache-aware switching mechanism executes a model switch only when the savings from switching exceed the cost of rebuilding the context, avoiding frequent switches made solely to save money.
Switching models causes context cache invalidation, requiring the re-injection of state such as codebase structure, task objectives, and completed steps via prompts, consuming additional tokens and potentially introducing errors.
Weave Router 2.0 is an open-source tool listed under Product Hunt's Open Source, Developer Tools, and Artificial Intelligence categories, built by Adam Cohen, Andrew Churchill, Brennan Lupyrypa, Drew Bailey, Steven, and others.
Forwarding requests between models from different vendors involves data flow and privacy compliance issues, which teams should evaluate thoroughly before adoption.
