Voidleap Code is a desktop agentic IDE from Voidleap that runs on your own machine, with every agent, skill, hook, and security rule left editable. You can change model in the middle of a thread, planning on one, implementing on another, and reviewing on a third without starting over, then read back the tokens, cost, latency, and cache hit rate for each. Opper ships inside the app as a provider rather than a base URL override, so you add your key once in settings and pick Opper models per turn.
