AI assistants and search decision
BromeAI
A technically capable developer can reproduce the core multi-model chat, model-switching, and file-chat features using existing open-source projects and provider APIs; the vendor's bundled single-subscription access and EU hosting/privacy guarantees are the main conveniences you give up.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All BromeAI alternatives, with the arithmetic →
What a replacement has to do
- User chats in a web client that proxies requests to multiple model provider APIs, preserves conversation context, and shows model-switch / comparison results.
What it still won’t have
- Unified single-subscription access to many proprietary models (the product bundles model access)
- Workflow engine and automation features (workflow engine listed on Pro plan)
- Priority support (listed on Pro plan)
- EU data hosting guarantee (Data Hosted in EU)
- Built-in image & video generation credits and integrations
What remains hard
- Compliance and regulation
GDPR Compliant Full compliance with the General Data Protection Regulation. Your rights are protected by the strictest privacy standards.
- Compliance and regulation
Data Hosted in EU All user data is stored within the European Union using Hetzner, a trusted European cloud provider.
- Brand trust

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a self-hosted multi-model chat proxy and web client using Next.js (React) for the frontend, Node.js/Express for the API gateway, Postgres for user and conversation storage, Redis for realtime presence/queues, and provider adapter modules for OpenAI, Anthropic, and Google. Core features in scope: single-user auth (email+password), chat UI with model selector and context-preserving model switch, provider adapters with per-request routing and basic rate-limiting, file upload + PDF text extraction and simple retrieval (embeddings optional), and subscription check stub (Stripe sandbox). Out of scope: bundled commercial reseller access to paid models, native mobile apps, enterprise multi-tenant billing. Include error handling, input validation, retries for provider failures, CI tests for adapters and chat flow, and deployment scripts (Docker + basic Hetzner-compatible instructions).

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
