Sparrowgate

What it does

Sparrowgate is a lightweight, open-source proxy router that protects you from unexpected cloud and AI billing shocks. It checks incoming requests and routes them across different AI providers based on cost and availability. As usage nears its limit, it automatically applies a cap — so your bill never crosses the line. Built for developers and startups who want to keep their server/API costs under control, without getting locked into a single provider.

A simple Python API router that checks requests and sends them to 2 different AI APIs. It automatically picks the best one to save your money and stop heavy billing leaks on your servers. - Mianabubaker/Sparrowgate

A reverse proxy gateway that sits in front of your LLM API calls, caches repeated prompts in a local SQLite DB, and routes short/simple queries to cheaper models. I built this because I kept seeing the same problem in my own projects: redundant API hits and tiny throwaway queries eating up budget for no reason. SparrowGate just sits between your app and the LLM provider, checks if it's seen the prompt before, and if not, decides whether it actually needs a big model or if a cheap one will do. No dashboard-heavy enterprise setup, no config hell — just a proxy you can drop in and forget about. pip install -r requirements.txt 2. Run Dashboard (UI Mode) python app.py 3. Run Proxy Endpoint (API…from github.com

  PipeGate – A Lightweight, Self-Hosted Proxy to Expose Local Servers2024 · github.com · ▲33

  Hi Hacker News, I’d like to introduce PipeGate, a lightweight, self-hosted proxy built with FastAPI. I created PipeGate as a fun little exercise to understand how tunneling services work under the hood. PipeGate allows you to expose your local servers to the internet, giving you full control over your setup.

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
