cloudflare-os
Cloudflare
Open-source agent workspace on Cloudflare Workers for chatting with agents, building sandboxed apps and enforcing guardrails.
Key features
- Agent Chat UI: Ask agents to complete tasks with built-in knowledge about how your company operates.
- Gadgets: Agents build small personal apps from scratch in a sandbox that can be safely shared with others.
- Gatekeepers Security Framework: Guardrails for agents and apps so non-technical users can experiment safely.
- Built-in Blueprints: Includes templates such as a slides blueprint for generating decks from a prompt.
- Integrations: Optional GitHub and Google integrations let agents work on repos and documents.
- Local and Cloud Deployment: Run the full stack locally on wrangler and workerd or deploy to your own Cloudflare account.
Best for
- An employee asks an agent to make slides for an upcoming customer meeting.
- A team asks for a collaborative whiteboard app built from scratch as a gadget.
- A product manager generates an issue dashboard for a GitHub repo.
- A user asks an agent to fix typos in an attached Google Doc.
- A company forks the project to build its own governed AI workspace.
- A security team enforces guardrails so non-technical staff can safely build apps.
Feynman
Companion
Open-source AI research agent that reads papers, ranks literature, drafts research and plans experiments from the terminal or a local workbench.
Key features
- Cited Research Briefs: Asking a research question returns a synthesized brief where each claim is tied to the paper or web source it came from, rather than an unsourced summary.
- PaperRank Scoring: Ranks papers on a topic with transparent evidence for citations, methodology, reproducibility and provenance so reading order is a decision you can inspect.
- Paper Access Resolver: Resolves a single DOI, arXiv ID, OpenAlex ID, PMID, PMCID or title against OpenAlex, arXiv/alphaXiv, DOI and Europe PMC, with optional full-text fetching.
- Local Science Workbench: `feynman serve` opens a standalone app with projects, sessions, chat, notebooks, compute, artifact previews and provenance in one place.
- Claim Auditing and Replication: Compares a paper's stated claims against what its code actually does, and generates replication plans with compute targets and gated experiment steps.
- Local and Hosted Models: Works with hosted providers via OAuth or API key and with local runtimes including LM Studio, Ollama, vLLM and a LiteLLM proxy.
- Skills-Only Install: The research skill library can be installed on its own into Claude, Codex or OpenCode projects without the terminal app or bundled runtime.
- Science Artifacts: Reports, data files, spreadsheets, notebooks, LaTeX, chemistry sketches and genomes are browsable together with versions, lineage and execution logs.
Best for
- Deciding What to Read: Ranking a fresh literature pile on a topic by reproducibility and methodology instead of citation count alone.
- Writing a Literature Review: Producing a review that separates where the field agrees from where questions remain open, with citations attached.
- Verifying a Paper's Claims: Auditing whether the results a paper reports are supported by the code and data it released.
- Planning a Replication: Turning a published finding into a concrete replication plan with a compute target and staged experiment steps.
- Running Deep Research Passes: Launching a multi-agent deep dive on a topic that synthesizes findings and verifies them before reporting.
- Keeping Research Local: Running the whole pipeline against a local model so unpublished work and private data never leave the machine.
- Adding Research Skills to a Coding Agent: Installing the skills bundle into an existing Claude or Codex project to get research workflows without a second app.
