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.
Fuser
Fuser
A creative workspace that unifies models and media on one canvas to design, iterate, and ship content.
Key features
- Unified Multimodal Canvas: A single workspace that lets users place, arrange, and combine outputs from different models and media types (image, audio, text) on one canvas to create composite assets and storyboards.
- Model Integration: Support for plugging in multiple generative models so creators can experiment with different model outputs side-by-side and switch model sources without leaving the workspace.
- Asset Management: Organize, version, and track creative assets and model outputs within projects to streamline iteration and avoid losing prior experiments.
- Collaborative Editing: Enable multiple users to work on the same canvas, share annotations and feedback, and iterate in real time to accelerate review and handoff.
- Export & Delivery: Export final assets in common formats and prepare deliverables for downstream tools or publishing platforms, reducing export friction.
- Experimentation Workflow Tools: Built-in controls for recording model parameters, comparing variant outputs, and reverting to previous iterations to support reproducible creative experiments.
- Fusion code generation that compiles multiple PyTorch ops into fused CUDA kernels
- Python bindings and integration with PyTorch
- Prebuilt nightly pip wheels for supported Python versions (examples: 3.10, 3.12)
- CMake-based build system and native C++ sources (csrc, runtime)
- Benchmark suite and examples for performance evaluation
- Tests and continuous integration (workflows present in repo)
- Supports build variants tied to stable vs nightly PyTorch to ensure ABI compatibility
- Includes CUTLASS integration and GPU-optimized kernels
Best for
- Multimodal Concepting: Combine images, audio clips, and text generations on one canvas to explore cross-medium creative concepts for campaigns or stories.
- Model Comparison & Selection: Test multiple generative models on the same input and compare outputs side-by-side to select the best result for production.
- Collaborative Content Production: Teams collaborate on visuals, scripts, and audio in a shared workspace to speed up review cycles and unify creative direction.
- Rapid Prototyping: Quickly assemble and iterate on mockups, storyboards, and asset collections to validate ideas before full production.
- Marketing Asset Creation: Produce and assemble campaign assets (banners, short videos, social posts) by mixing model-generated content with manual edits in one environment.
- Creative Experiment Tracking: Record parameter settings and variant histories for reproducible experiments and to inform future model-driven design decisions.
- Accelerating PyTorch models by fusing operator graphs into fewer, higher-throughput GPU kernels
- Research and development of compiler optimizations for deep learning
- Benchmarking and comparing fused vs unfused kernel performance
- Building custom operator fusion strategies for specialized workloads
- Integrating fused kernels into model deployment pipelines to reduce latency
