Self-hosted

Can be run on hardware you own or rent, with no vendor in the data path.

Private cloud

On-premise (enterprise plan)

On-premise deployment is offered, typically only on an enterprise agreement.

• self_hostedPrivate company knowledge base (self-hosted RAG)Open WebUI as the employee interface, vLLM serving a Qwen2.5-14B-Instruct model on a single 24 GB GPU, PostgreSQL with pgvector for chats and embeddings, and OIDC single sign-on — all in Docker on one server in your office or colocation rack. Ollama replaces vLLM for teams under about 20 users; a 48 GB GPU lets you run a 32B model for better answers.
• private_cloudPrivate-cloud RAG in a single regionA GPU instance in one region running vLLM and Open WebUI, a managed PostgreSQL with pgvector for chats and embeddings, object storage for the original files, and your existing identity provider for sign-in. Same software as the on-premise recipe; different trust boundary.
• self_hostedContract review and clause extractionDocling converts the contract to structured text with layout preserved; a 32B open-weight model on vLLM fills a JSON schema of clause fields under constrained decoding; results land in PostgreSQL with pgvector for search and precedent lookup; a reviewer approves in the UI.
• self_hostedPrivate ChatGPT on your own serverOllama serving an open-weight model on one GPU, Open WebUI in front of it for accounts, chats and admin controls, both in Docker on a single machine. Deliberately the smallest thing that works: no vector database, no connectors, no cluster.

Tools that serve at least one of the same use cases. Open-source alternatives, with the repository facts behind them, have their own page.

Issue-spotting for this tool under each published jurisdiction, built from the same rules an answer uses. A page with nothing researched says so rather than filling the gap.

• europeOpen WebUI in European UnionRegulation (EU) 2016/679 (GDPR). Directly applicable in every Member State and unamended as of the review date. An AI deployment engages Articles 5 and 6 on principles and lawful basis, 9 on special categories, 13 and 14 on information, 22 on decisions based solely on automated processing, 28 on processors, 32 on security, 35 on impact assessments and Chapter V on transfers out of the EEA. Member States retain room to legislate on employment, which is where Germany’s BDSG § 26 comes in.
• europeOpen WebUI in United KingdomUK GDPR, as retained and amended, together with the Data Protection Act 2018. The core duties are unchanged in shape — lawful basis, transparency, purpose limitation, security, processor contracts, international transfers — but the automated decision-making regime now sits in Articles 22A to 22D rather than Article 22. Article 22A defines a decision as based solely on automated processing where there is no meaningful human involvement, and a significant decision as one producing a legal or similarly significant effect. Whether human involvement is meaningful must be considered in light of the extent to which the decision is reached by profiling.
• north-asiaOpen WebUI in China (mainland)Personal Information Protection Law (PIPL), in force since 1 November 2021. Requires a lawful basis, notice, and separate consent for defined activities including providing personal information to a third party, publicising it, processing sensitive personal information and sending it abroad. Sensitive personal information needs a specific purpose, sufficient necessity and strict protective measures. A personal information protection impact assessment is required before high-risk processing, including any outbound transfer. Article 38 sets the outbound routes. Entrusted processing must be governed by a contract that fixes purpose, period, method and protective measures.
• north-asiaOpen WebUI in Hong KongPersonal Data (Privacy) Ordinance (Cap. 486). The Ordinance applies to any person who controls the collection, holding, processing or use of personal data, and works through six Data Protection Principles in Schedule 1 covering collection, accuracy and retention, use, security, openness and access. Data processors are not directly regulated: the data user stays responsible and must impose the requirements on its processors by contract or other means. Contravening a Data Protection Principle is not itself an offence, but the Commissioner may issue an enforcement notice and contravening that notice is.
• north-asiaOpen WebUI in JapanAct on the Protection of Personal Information (個人情報の保護に関する法律, Act No. 57 of 2003). Requires the purpose of use to be specified and adhered to, restricts acquisition and third-party provision, sets security control measures, and imposes duties when personal data is entrusted to a contractor — which is what using a model provider usually is. Transfers to a third party in a foreign country are subject to their own regime, with an information duty to the individual. The e-Gov entry currently shows unenforced provisions pending, so check which version applies before relying on an article number.
• north-asiaOpen WebUI in South KoreaPersonal Information Protection Act (개인정보 보호법). The version in force is Act No. 20897, effective 2 October 2025. It sets consent and alternative bases, purpose limitation, retention limits, security duties, breach notification and cross-border rules, and since March 2023 has carried Article 37-2, the right of a data subject to object to or refuse a decision made by a completely automated system — expressly including systems applying artificial intelligence — where that decision significantly affects their rights or duties. An amendment promulgated on 10 March 2026 takes effect on 11 September 2026.
• north-asiaOpen WebUI in TaiwanPersonal Data Protection Act (個人資料保護法). Applies to public and non-public agencies, with separate collection and use rules for each. Notice at collection, purpose limitation, and a set of statutory bases are the core; special categories including medical records, genetic data, sexual life, health examination and criminal records are subject to a narrower regime. Article 21 lets the competent authority restrict international transfer in defined circumstances — under the text in force, that is the central sector regulator, and restrictions are issued sector by sector rather than as a general adequacy list.
