Why we included this project

Sparrow is a self-hosted document processing platform: you submit a document over REST and get back schema-validated JSON, with nothing sent to a third-party cloud. It pairs OCR preprocessing with vision and text LLMs, and the pipeline is pluggable, so you can choose a vision-based parser, an instruction-calling model, or orchestrated agents depending on the task. Backends span MLX, vLLM, Ollama, and Hugging Face, and the instruction and agent APIs go beyond extraction to handle validation, decision-making, and multi-step workflows. A web UI and dashboard cover monitoring. If your team routinely turns invoices, receipts, bank statements, forms, or tables into structured records, this is a practical way to do it on your own hardware.
