The verification layer is outranking the application layer on Product Hunt.

August 15's board leads with Inferock Bench at 154 upvotes, a local open-source proxy that sits between your app and OpenAI, Anthropic, Gemini or OpenRouter-shaped calls and emits a per-call billing-integrity receipt. It catches streams cut mid-sentence that were still billed, empty replies with billed tokens, token counts that don't match visible output, retries that may have doubled a charge, and missed cache discounts. Runs through npx inferock-bench with your provider key never leaving the machine. Product Hunt Application-layer agents sit lower: Zetik at #2 with 106, Attyn at #4 with 94, SalesCloser.ai at #7 with 91. Add CodeRabbit's raise three days earlier and the pattern is legible. The durable product in an agent stack is the receipt, the review, or the gate.
