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.
Kombai
Kombai (kombai-io)
An AI agent for frontend development that builds, refactors, tests, and improves frontend apps with deep browser and repo access.
Key features
- Specialized Frontend Skillset: Understands modern frontend frameworks and patterns (React, TypeScript, component libraries, CSS frameworks) and generates idiomatic, production-ready UI code.
- Deep Browser Access: Inspects and interacts with live pages and DOM, enabling tasks like UI fixes, end-to-end adjustments, and direct browser-driven testing and validation.
- Repository-Level Editing & Multi-Threaded Workflows: Operates across a code repository, runs multi-threaded tasks (threads) to build and refactor features, and can create commits/branches with changes.
- Automated Refactoring & Code Improvement: Performs targeted refactors (component extraction, style migrations, accessibility fixes) and iteratively improves code quality across codebases.
- Test Generation & QA Automation: Produces and runs frontend tests, helps identify regressions, and generates artifacts to validate behavior after changes.
- CMS & Data Integration Support: Wires frontend code to content sources (examples include DatoCMS) and fetches dynamic content to produce integrated, data-driven pages.
- Production-Ready Output & Tooling Support: Emits build-ready code and project scaffolding compatible with common toolchains (Vite, bundlers, UI libraries) to shorten time-to-deploy.
- Generate production-ready React + Tailwind code from screenshots and design files
- Deep browser access for inspecting, interacting with, and modifying web pages
- Automated refactoring and code improvements for frontend projects
- Automated testing and validation of frontend changes
- Visual template/HTML editor and layout editing to produce functional HTML/CSS outputs
- VS Code extension for in-editor assistance and live editing workflows
- Integration capability with headless CMSs (examples show DatoCMS usage)
- Support for modern frontend stacks and libraries (React, TypeScript, Vite, Antd)
- Multi-thread orchestration to run multi-step build/refactor flows
Best for
- Building a complete production frontend from specs or designs: generate React/TypeScript pages, wire them to a CMS, and produce deployable code.
- Adding features to existing repositories: implement new pages or settings (e.g., roles & permissions) and commit changes directly into the project repo.
- Large-scale refactoring: modernize UI codebases by extracting components, migrating styles, and improving maintainability across many files.
- Creating visual website editors or template builders: generate editable templates and output functional HTML/CSS/JS for template-driven products.
- Prototyping and converting designs into code: turn screenshots or design specs into responsive, production-ready frontend code to accelerate iteration.
- Automating frontend testing and QA: generate unit/integration tests, run validations in-browser, and detect regressions after automated changes.
- Convert screenshots or design files into production-ready React + Tailwind code
- Build responsive websites with dynamic content from headless CMSs
- Add features to existing frontend repositories (e.g., roles & permissions pages)
- Refactor and improve UI codebases and component libraries
- Visually edit templates and export functional HTML/CSS for deployments
- Accelerate frontend development workflows inside editors like VS Code
