You should look into Kilo Pass by Kilo Code (https://kilo.ai/features/kilo-pass). It's basically a fixed subscription and your credits roll over each month, and you get free extra credits too which are used up first before paid credits. It's similar to paying for Cursor except the credits roll over which is why I'm contemplating moving to it, because I don't want to be locked into any one LLM provider the way Claude Code or Codex make you become.
I was wondering how KiloCode Kilo Pass pricing compared to OpenRouter's top-up pricing, and did some digging and discovered the main difference is that OpenRouter provides a standard API key (sk-or-...) that works in any application (LangChain, curl, your own Python apps), while Kilo Pass credits are tied to the Kilo Gateway, which is designed to power the KiloCode Extension (VS Code/JetBrains) and CLI. KiloCode does not appear to allow you generate a "Kilo API Key" to use in your external Python scripts or third-party apps. But the monthly bonus credits are sweet.
Yes, it's for development not deployment.
