The Free plan costs nothing, and access is listed for the web and self-hosted deployments. Its homepage says the source code is available on GitHub for reading, review, or contribution. The repository describes a Next.js application using Mixtral through Together AI, LangChain.js, and Chroma Cloud. Chroma Cloud supplies hybrid dense and sparse vector search with Qwen and SPLADE embeddings. Bytescale stores PDFs, Clerk handles authentication, and Vercel hosts the application and Postgres database; Neon is an alternative database for self-deployment. The template can be deployed to Vercel or another host after configuring service credentials. Scanned PDFs are not supported.
