Tabslip is a local gateway that records receipts for an app’s AI API requests, including the model reported by the provider, costs, and timing.

Landing page captured for the 2026-10-25 issue.

For: Developers routing app requests through AI providers
Worth noticing: Each receipt uses a locally created Ed25519 key; the provider-comparison examples are explicitly simulated.

Field notes

The documented flow starts a gateway at 127.0.0.1:4545 and changes an SDK’s base URL while retaining its provider and API key; examples cover OpenAI, Anthropic, OpenRouter, and Ollama. Tabslip says receipts are signed with a locally generated Ed25519 key and separate provider-reported values from measurements or estimates, with offline verification documented. The comparison examples are simulated, and the site warns that real test calls may cost money.
