Hi! We're Arc53, a UK-based team building open-source AI infrastructure used by 17,000+ developers worldwide.

We maintain:

  • DocsGPT — private AI platform for agents, assistants, and enterprise search. Agent Builder, deep research, document analysis, multi-model support.
  • fast-ebook — fast Rust-based EPUB library for Python.
  • llm-price-compass — GPU benchmarks and per-token cost comparisons across cloud providers.
  • doc2md — convert PDFs and images into clean markdown.
  • ...and more across the AI tooling stack.

Where your sponsorship goes

Your support funds the maintainer team, ongoing work on our open-source projects, and ecosystem tools the community depends on — keeping everything free, open, and actively developed.

Why sponsor us

Sponsoring Arc53 unlocks tangible benefits depending on tier: priority support on issues, deployment and integration help, roadmap influence, recognition in our README and on docsgpt.cloud, and direct access to the maintainers. Companies relying on DocsGPT in production: the higher tiers are built for you.

1 sponsor has funded arc53’s work.

@arc53

Our first milestone toward sustainable funding. 10 monthly sponsors lets us commit more maintainer time to keeping DocsGPT and our open-source tools moving forward.
