About

Promptoll

Read full description

Promptoll is the AI gateway for developers who use more than one model. Connect once and reach every major LLM โ€” GPT-5.5, Claude, Gemini, DeepSeek and more โ€” through a single OpenAI-compatible API. No new SDKs, no rewrites: point your existing OpenAI client at Promptoll and switch models with a single line. WHY PROMPTOLL โ€ข One API, every model. Drop-in OpenAI compatibility means your existing code just works. โ€ข One key for everything. Generate an API key and call any model โ€” no separate accounts, no scattered billing. โ€ข Pay as you go. Top up a balance and pay only for what you use. No subscriptions, no minimums. โ€ข Full cost transparency. Every request is logged with model, token count, latency and exact spend. โ€ข Smart routing. Optionally let the gateway auto-route to the cheapest equivalent model and cut your bill. IN THE APP โ€ข Dashboard โ€” your balance, request volume, token usage and spend at a glance. โ€ข Chat โ€” talk to any model from your phone and switch instantly with the model picker. โ€ข API Keys โ€” create, name and revoke keys in seconds. โ€ข Logs โ€” inspect every request with a full model, latency and cost breakdown. โ€ข Settings โ€” manage your account, language and routing preferences. BUILT FOR DEVELOPERS Promptoll speaks the OpenAI Chat Completions format, so it works out of the box with the OpenAI SDK, the Vercel AI SDK, LangChain and any OpenAI-compatible client. Use the same base URL and key across web, mobile and server. Start free, add credit when you need it, and keep every token accounted for.

About

Murmur BLE Shell

Features
Read full description

murmur turns your phone into a remote control for a Raspberry Pi โ€” no Wi-Fi, no network setup, no port forwarding. Just Bluetooth Low Energy (BLE), directly between your phone and the Pi. HOW IT WORKS Install the open-source murmur daemon on any Raspberry Pi running Linux, pair your phone with it over Bluetooth, and you get: โ€ข Shell mode โ€” a real interactive terminal on the Pi, right from your phone. โ€ข Agent mode โ€” describe what you want in plain English ("what's eating my disk space?", "set up a static IP") and an AI agent plans and runs the shell commands for you, showing every command and its output as it goes. BRING YOUR OWN API KEY Agent mode is powered by your own Anthropic Claude, OpenAI, or Google Gemini API key โ€” entered once in Settings, stored only in your phone's secure keychain. murmur has no backend server and no account system. The only network calls it makes are the LLM requests you trigger yourself, using your own key. WORKS OFFLINE ON THE PI SIDE The Raspberry Pi never needs an internet connection. It just needs Bluetooth and the murmur daemon running. Good for headless boxes, home labs, and devices you'd rather not put on a network at all. PRIVACY BY DESIGN Everything murmur stores โ€” the Bluetooth pairing key, your API key, an optional per-device sudo password, and saved agent conversations โ€” stays on your phone in the OS-level secure store. One tap in Settings wipes it all. OPEN SOURCE Both the daemon and the app are open source: github.com/nekonihq/murmur
