GoKawiilDeveloper releases Prospero, a lightweight C++ coding harness for local LLMs
A developer known for the nullprogram.com blog has released Prospero, an open-source coding harness built in C++ with a Dear ImGui interface, designed to connect AI models to developer tools for agentic coding tasks. The tool claims to use roughly two orders of magnitude less memory than existing harnesses, which the author says are typically built on resource-heavy web stacks. Prospero does not bundle any model provider, requiring users to supply their own backend such as llama.cpp, OpenRouter, or the Anthropic or OpenAI APIs.
