OnCell open-sources one-file research, support agents

Hot take: this is less about breakthrough agent behavior and more about packaging the “hard parts” of agent infra into a clean demo that other builders can actually copy.

• –The research repo is positioned as a Perplexity-like experience: web search, structured synthesis, source cards, follow-up context, and searchable research history.
• –The support repo is a straightforward RAG app with citations, per-customer memory, and an admin upload flow, which makes it easier to ship a usable doc bot than to wire up a full stack from scratch.
• –The big differentiator is the OnCell abstraction: isolated runtime, storage, DB, and search per user/session, which removes a lot of plumbing that usually bloats small agent demos.
• –The “one file backend” claim is compelling for adoption, but the long-term question is whether the abstraction stays simple once teams need more custom tools, permissions, or observability.
