ARBR vs Unstructured: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of ARBR and Unstructured — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
ARBR
Gyde & Domkundwar Foundation
Open-source, MIT-licensed AI gateway and control plane that routes, governs and observes every LLM request behind one OpenAI-compatible endpoint.
Key features
- OpenAI-Compatible Routing: A single drop-in endpoint over every major provider, with rules, difficulty-aware selection, cost guardrails and automatic fallback choosing the model per request.
- In-Path Governance: Budgets, rate limits, output guardrails, prompt-injection checks and kill switches enforce policy before inference rather than auditing it afterwards.
- Structured Observability: Cost, latency, tokens and routing decisions are emitted as structured events attributed by application, team, model and user, viewable in local dashboards or exported to OpenTelemetry backends such as Datadog, Grafana and Prometheus.
- LLM-Judge Evaluation: A sample of live traffic is scored for quality so requests can be routed to the cheapest model that provably clears the bar, rather than optimising on price alone.
- Safe Model Deployment: Canary and shadow new models against real traffic with regression gates that block promotion until evaluations pass, plus instant rollback.
- Broad Provider Coverage: One layer over Anthropic, OpenAI, Google Gemini, Amazon Bedrock, Azure OpenAI, Vertex AI, Groq, DeepSeek, Moonshot, xAI and Mistral, plus LiteLLM and NVIDIA NIM, with pricing and benchmark data for over 3,000 models.
- Drop-In SDK Compatibility: Change only the base URL and existing OpenAI SDKs, agent frameworks and chat UIs keep working, gaining streaming chat completions, embeddings, a realtime voice proxy and JavaScript and Python SDKs.
- Self-Hosted and MIT Licensed: The full control plane runs inside your own infrastructure under an MIT licence, with a hosted option available for teams that do not want to operate it.
Best for
- LLM Cost Reduction: Route summarisation and extraction traffic to cheap small models while reserving frontier models for analysis, cutting spend without hand-editing every call site.
- AI Spend Attribution: Give finance and engineering a per-application, per-team and per-user breakdown of token spend so AI budgets can be owned by the groups that generate them.
- Enterprise AI Governance: Enforce departmental budgets, rate limits and kill switches in the request path so a runaway agent cannot exhaust a quarter's inference budget.
- Provider Risk Mitigation: Keep applications provider-neutral behind one endpoint with automatic fallback, so a single vendor outage or price change does not require a code change.
- Model Migration Testing: Shadow or canary a newly released model against production traffic and let regression gates decide whether it is promoted.
- Prompt-Injection Defence: Apply output guardrails and prompt-injection checks centrally for every application instead of reimplementing them per service.
Unstructured
Unstructured
Open-source ETL platform that converts complex documents into structured data for LLMs and GenAI workflows.
Key features
- Multi-format Ingestion: Supports a broad set of input types (PDF, HTML, DOCX, PPTX, XLSX, EPUB, images, emails, CSV/TSV, compressed archives) to ingest documents from varied sources and normalize them for downstream processing.
- Modular Bricks and SDKs: Provides reusable, open-source building blocks (bricks) and language SDKs to assemble custom preprocessing pipelines for parsing, cleaning, and transforming document content.
- Pipeline Orchestration & Enrichments: Routes data through dynamic transformation pipelines that perform partitioning, enrichment, metadata extraction, and content normalization to produce structured outputs tailored for LLMs.
- Layout Parsing & Chipper Model: Includes layout and document structure analysis (layout parsing) to extract tables, figures, headings, and positional context from complex page layouts for accurate content segmentation.
- Chunking & Embedding Preparation: Implements intelligent chunking and embedding generation workflows to create LLM-friendly segments and vectors, improving retrieval, RAG, and semantic search performance.
- Hosted API & Local Libraries: Offers a hosted Unstructured API (API keys required) for cloud-based processing alongside open-source local libraries for on-prem or custom deployments, enabling flexible integration models.
- Enterprise Platform Capabilities: Provides production-grade Platform features—continuous ingestion, monitoring, partitioning strategies, and scalability—targeted at enterprise workflows and compliance needs.
- File-type Analytics & Metrics: Collects analytics on processed document types and transformation success to help operators measure ingestion quality and pipeline performance.
- Convert documents to structured data (supports PDFs, HTML, Word, images, tables, graphs)
- Modular components ("bricks") for building custom preprocessing pipelines
- Dynamic transformation and enrichment pipelines for routing and improving data quality
- Partitioning and chunking to prepare content for LLM consumption
- Embedding support and integration points for vectorization
- Layout parsing and inference models (separate inference repository)
- Python SDK and libraries (unstructured, unstructured-api, unstructured-inference)
- Containerized deployment options (Dockerfile present in repo) and Makefile-driven install
- Apache-2.0 open-source licensing for core libraries
- Enterprise Platform for production-grade workflows, continuous automated processing and scaling
Best for
- Preparing LLM Training & RAG Corpora: Clean, partition, and chunk large collections of PDFs, manuals, and reports into semantically coherent passages and embeddings for retrieval-augmented generation and model fine-tuning.
- Automated Document Ingestion for Knowledge Bases: Continuously ingest and transform new documents (contracts, policies, manuals) into structured records for searchable knowledge bases and Q&A assistants.
- Table and Figure Extraction for Data Pipelines: Parse complex tables, figures, and embedded images from financial reports or scientific papers to convert them into structured datasets for analytics or downstream models.
- Compliance and Contract Analysis: Extract clauses, metadata, and named entities from legal and regulatory documents to populate contract management systems and support compliance workflows.
- Invoice/Receipt Processing: Normalize and extract line-items, totals, dates, and vendor information from invoices and receipts to automate AP workflows and accounting ingestion.
- Migration of Legacy Documents: Convert large legacy document collections (scanned PDFs, archived emails, disparate formats) into structured, searchable formats to modernize enterprise data stores.
- Prototype to Production Pipelines: Use open-source bricks to prototype document parsing locally, then scale to the Unstructured Platform for continuous, monitored production processing with enterprise controls.
- Preprocessing document corpora to create high-quality input for retrieval-augmented generation (RAG) pipelines
- Extracting tables, figures, and structured fields from PDFs and scanned documents
- Continuous ingestion and enrichment of enterprise documents for knowledge bases
- Generating embeddings and chunked passages for semantic search over documents
- Receipt, invoice, and financial filings parsing (example pipelines and archived repos exist)
- Building document Q&A or chatbot applications using cleaned, structured document content
