Flowstep: Your AI Design Assistant
Flowstep
Generates production-ready UI from text prompts with chat-driven iteration, Figma export, code export, and IDE integration via MCP.
Key features
- Production-ready UI Generation: Converts plain-text prompts into structured, production-quality user interfaces ready for further refinement or export.
- Chat-driven Iteration: Provides a conversational interface to iteratively tweak layouts, components, and visual details without leaving the tool.
- Figma Export: Copies or syncs generated UI directly to Figma as editable layers and components for designer workflows.
- Code Export: Exports implementation-ready frontend code from designs to accelerate developer handoff and reduce manual translation.
- IDE Integration via MCP: Connects to developers' IDEs through MCP to pull designs and code directly into development environments, streamlining integration.
- Generate production-ready UI from natural language text prompts
- Chat-based iterative refinement of generated UI
- Copy or sync designs to Figma
- Export frontend code from generated designs
- Connect IDEs via MCP for direct developer integration
- Support for rapid prototyping and design-to-development handoff
Best for
- Rapid MVP UI Creation: Produce initial, production-ready interfaces from product requirements to accelerate minimum viable product development.
- Designer–Developer Handoff: Export polished designs to Figma and generate code to minimize manual translation and speed up implementation.
- Iterative Design Exploration: Use the chat interface to quickly explore multiple layout and style variations with instant updates.
- Frontend Acceleration for Teams: Generate reusable components and export code to reduce repetitive UI implementation work across projects.
- Embedding into Dev Workflows: Connect via MCP to bring generated UI and code directly into a developer's IDE for faster integration and testing.
- Rapidly create UI mockups and prototypes from product requirements or user stories
- Accelerate design-to-code handoffs by exporting production-ready frontend code
- Enable designers to push iterations quickly into Figma for collaboration
- Allow developers to connect their IDE and import UI artifacts into the codebase via MCP
- Prototype new product flows and validate user interfaces with stakeholders

Pi Web
agegr
Local web UI for the Pi coding agent — browse sessions, switch worktrees, manage models, and chat beside your project files in a browser.
Key features
- Session Browser: Reads local Pi session files and organizes prior conversations by project for quick resume.
- Fork and Continue: Continue from any earlier message or fork a session into a separate route to try alternatives safely.
- Git Worktree Switcher: Switch between Git worktrees from the sidebar to work on multiple branches in parallel.
- File Preview: Side-by-side chat and project file browser that previews source, docs, images, audio, and PDFs.
- Model and Skill Manager: Configure models, API keys, run model tests, and toggle skills from the web UI instead of CLI flags.
- Local-Only Runtime: Runs on http://127.0.0.1 by default so session data and code never leave the developer's machine.
Best for
- Resume Prior Work: Reopen a conversation from last week by project instead of scrolling terminal history.
- Safe Experimentation: Fork a session to try a risky refactor without losing the original conversation state.
- Parallel Branch Work: Switch Git worktrees mid-session to jump between feature branches in one workspace.
- Model Comparison: Rerun the same task against different configured models to compare output quality.
- In-Browser Code Review: Preview generated diffs and project files beside the chat without leaving the browser.
