View guide →Unstract — LLM-driven extraction of unstructured data, built for API deployments and ETL pipeline workflows.
unstract is an open-source rag & knowledge project by Zipstack (Zipstack/unstract on GitHub). It has 7,277 GitHub stars and 718 forks, is released under the AGPL-3.0 license, and was last updated on GitHub on 8 October 2026.
Pick a representative document type and write down the exact fields and JSON shape your downstream system needs.
Clone Zipstack/unstract from GitHub (or use the install path in the run steps below) and skim its README for the parts relevant to your goal.
Clone the repo and start the platform with its Docker Compose setup, keeping the generated encryption key safe — losing it makes existing adapter credentials inaccessible.
Log in locally, build one extraction for your sample document, test it on a few files, then deploy it as an API endpoint.
Extracts structured JSON from unstructured documents using LLMs, aimed at document-AI and IDP workloads.
Extractions are designed to be deployed as APIs, not just run interactively in a notebook.
Fits extraction into ETL pipeline workflows for recurring document processing.
A platform UI for designing and iterating on extraction prompts and schemas.
Run locally with Docker Compose, pull a specific version tag, upgrade in place, or build images locally.
Exposes MCP server capability so agent tooling can call extraction as a tool.

git clone https://github.com/Zipstack/unstract.git
cd unstractClone the repository and follow the README quickstart to start the platform with Docker.
git clone https://github.com/Zipstack/unstract.git
cd unstract # then start with Docker Compose per the README quickstartVisit the local frontend, log in with the README's default local credentials, and build your first extraction.
# Open http://frontend.unstract.localhost — default local login is in the README; change it after first useZipstack, through the Zipstack/unstract repository, with the product site at unstract.com.
Yes — the project is open source under the AGPL-3.0 license as recorded for this listing. See the license terms for any conditions on redistribution.
Extraction calls LLMs, so you configure your own LLM provider credentials as adapters; Unstract itself is open source under AGPL-3.0, and losing the platform encryption key locks existing adapter credentials.
Template IDP breaks when layouts change and needs per-format rules. Unstract uses LLM extraction defined by prompts and schemas, deployable as APIs and pipelines — more flexible across document variety, with model cost per document instead of template maintenance.
Clone the repository (or use the documented installer), follow the install and configure steps on this page, and run the smallest real task first — log in locally, build one extraction for your sample document, test it on a few files, then deploy it as an API endpoint.
