What is UpstreamKit?

UpstreamKit is a Python-powered Windows GUI application that proxies OpenAI and Anthropic API calls through a local HTTP server. Enter your upstream base URL, API key, and model in the interface—it overrides client keys/models, converts request formats bidirectionally, and exposes a local endpoint like http://127.0.0.1:8787 for apps to hit. It tracks token usage (with cache hit/miss breakdowns), logs requests verbosely, and runs in the system tray for background operation, solving custom upstream routing without scripting your own server.

Why is it gaining traction?

The intuitive Windows GUI beats CLI proxies or raw scripts—test connections with one click, preview logs live, and monitor session/total tokens precisely for cost control. Tray support and auto-config saving make it frictionless for repeated use, while user ID sanitization and stream handling add polish. Devs dig the no-fuss OpenAI-Anthropic bridging for mixed-toolkit workflows.

Who should use this?

Windows devs running AI in GitHub Actions, runners, or scripts needing local API relays alongside tools like Windows GitHub CLI or SSH keys. AI desktop users (e.g., Claudecode) overriding models/upstreams via GUI, or teams automating API tests with token stats in Windows GUI programming setups.

Verdict

Worth a spin for Windows API proxying niches—functional GUI, solid logging, and token tracking shine despite 11 stars and 0.9% credibility score hinting at early maturity. Fork and add tests/docs to scale it.
