Open WebUI
Self-hosted chat interface for local and remote language models, adding document retrieval, model switching, per-user workspaces, tool calling and an extensible pipeline layer.
Flowise
Visual builder for language-model applications, wiring retrieval, memory, tools and model nodes on a canvas and exposing the finished flow as an API endpoint or embeddable chat widget.
LiteLLM
Gateway fronting more than 100 model providers behind a single OpenAI-compatible API, adding routing rules, fallback chains, retries, per-key spend limits and request logging.
Whisper
Speech recognition service wrapping OpenAI's Whisper models, transcribing and translating audio across many languages with timestamps, served over an HTTP endpoint.
Piper
Fast neural text-to-speech engine that runs entirely on CPU, producing natural speech from small ONNX voice models at real-time speed on hardware as modest as a single-board computer.
Redis
In-memory data store used as a cache, message broker and ephemeral database, offering strings, hashes, lists, sets, sorted sets and streams, with optional persistence to disk.
Caddy
Web server and reverse proxy that obtains and renews TLS certificates automatically, supports HTTP/3, and is configured either by a short text file or entirely over an API.
