AI assistants and search decision
OpenAssistantGPT
Because the project is open-source and the core features (crawler, RAG, OpenAI Assistant proxy, embeddable widget) are implementable by one developer in about a week, a technical user can self-host or build a narrow equivalent; however the vendor's hosted SaaS-level polish, enterprise features, and managed operations are nontrivial to reproduce.

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 OpenAssistantGPT alternatives, with the arithmetic →
What a replacement has to do
- Accept a website URL, crawl and extract content, embed and index text, proxy chat messages to OpenAI Assistants (with tool calls), render a chat widget on a website, handle file uploads for RAG.
What it still won’t have
- Hosted multi-tenant SaaS operations, uptime SLA and scaling
- Enterprise features such as SAML/SSO and SLA guarantees
- Polished UI, whitelabeling and analytics as provided by the vendor
- Company-provided support, onboarding and managed backups
What remains hard
- Product polish and ongoing maintenance

Runnable build prompt
Build a self-hostable OpenAssistantGPT-compatible chatbot platform using Node.js + TypeScript (Next.js for UI), Postgres + PGVector for vector storage, and a small Express/Next API server to proxy to OpenAI Assistants. Core features in scope: 1) website crawler and HTML extractor, 2) embeddings ingestion and similarity search, 3) backend chat proxy that composes RAG responses and supports simple tool calls, 4) embeddable chat widget and dashboard for threads, 5) file upload parsing (CSV, images) and ingestion. Out of scope: multi-tenant enterprise features (SAML/SSO), billing UI, advanced analytics, and autoscaling. Include error handling, logging, CI tests for crawler, ingestion, and chat flows, and a Docker Compose setup plus a one-page README with deployment steps and env var examples.

- Price verified on pricing page+3
- Evidence score99
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.
