Roadmap: Node Banana Multi-Provider Support
Overview
Transform Node Banana from a Gemini-only image generator into a multi-provider platform supporting Replicate and fal.ai. The journey builds provider infrastructure first, then adds dynamic model discovery, refactors the generate node for flexibility, creates a searchable model browser, adds local image serving for URL-based providers, and finishes with video support and polish.

✅ v1.0 Multi-Provider Support (Phases 1-6) - SHIPPED 2026-01-11
Phase 1: Provider Infrastructure
Goal: Users can configure Replicate and fal.ai API keys in settings, with keys securely stored Depends on: Nothing (first phase) Research: Unlikely (internal UI patterns, Zustand state management) Plans: 2 plans
Plans:
- 01-01: Provider settings UI in ProjectSetupModal
- 01-02: Provider abstraction layer and types
Phase 2: Model Discovery
Goal: App can fetch and cache available models from enabled providers at runtime Depends on: Phase 1 Research: Likely (external APIs) Research topics: Replicate model listing API endpoints, fal.ai model discovery endpoints, response schemas and pagination Plans: 3 plans
Plans:
- 02-01: Replicate model fetching API route
- 02-02: fal.ai model fetching API route
- 02-03: Model caching and unified model interface
Phase 3: Generate Node Refactor
Goal: NanoBanana node becomes GenerateImage node supporting any provider's image models Depends on: Phase 2 Research: Unlikely (internal refactoring using existing patterns) Design decision: Separate nodes for image vs video generation (GenerateVideo added in Phase 6) Plans: 3 plans
Plans:
- 03-01: Rename NanoBanana to GenerateImage, add model selector (image models only)
- 03-02: Provider-specific execution in generate API route
- 03-03: Backward compatibility for existing workflows
Phase 4: Model Search Dialog
Goal: Users can browse models via floating action bar icons and searchable dialog Depends on: Phase 3 Research: Unlikely (internal UI using React patterns) Plans: 2 plans
Plans:
- 04-01: Floating action bar with provider icons
- 04-02: Model search dialog with filtering and selection
Phase 5: Image URL Server
Goal: Local API endpoint serves workflow images as URLs for providers requiring URL inputs Depends on: Phase 3 Research: Unlikely (Next.js API routes, existing patterns) Plans: 2 plans
Plans:
- 05-01: Image serving endpoint and URL generation
- 05-02: Integration with generate node for URL-based providers
Phase 6: Video & Polish
Goal: GenerateVideo node for video generation, video playback, custom parameters, edge cases Depends on: Phase 5 Research: Likely (video handling) Research topics: HTML5 video element for base64/blob URLs, provider response formats for video content Design decision: GenerateVideo as separate node type (not combined with GenerateImage) Plans: 4 plans
Plans:
- 06-01: GenerateVideo node with video-capable model selector
- 06-02: Video playback in output node
- 06-03: Custom model parameters from provider schemas
- 06-04: Edge case handling and final polish
🚧 v1.1 Improvements (In Progress)
Milestone Goal: Fix connection issues, improve error visibility, add video history, auto-size nodes, and polish UI
Phase 7: Video Connections
Goal: Fix video handle connections to only allow valid targets (generateVideo, output) Depends on: Phase 6 Research: Unlikely (internal connection validation patterns) Plans: TBD
Plans:
- 07-01: TBD (run /gsd:plan-phase 7 to break down)
Phase 8: Error Display
Goal: Better error visibility with overlay display, not hidden by previous output Depends on: Phase 7 Research: Unlikely (internal UI patterns) Plans: TBD
Plans:
- 08-01: TBD (run /gsd:plan-phase 8 to break down)
Phase 9: Video History
Goal: Add history carousel for generated videos matching image history pattern Depends on: Phase 8 Research: Unlikely (existing image history pattern) Plans: TBD
Plans:
- 09-01: TBD (run /gsd:plan-phase 9 to break down)
Phase 10: Node Autosizing
Goal: Auto-size nodes to output dimensions and aspect ratio Depends on: Phase 9 Research: Unlikely (React Flow node sizing) Plans: TBD
Plans:
- 10-01: TBD (run /gsd:plan-phase 10 to break down)
Phase 11: UI Polish
Goal: Flora UI alignment, header UI improvements, project settings, provider logos on nodes Depends on: Phase 10 Research: Unlikely (internal UI work) Plans: TBD
Plans:
- 11-01: TBD (run /gsd:plan-phase 11 to break down)
Phase 12: Model Improvements
Goal: Verify Replicate image models work, extend model cache TTL Depends on: Phase 11 Research: Likely (Replicate API behavior verification) Research topics: Replicate image model endpoints, cache invalidation strategies Plans: TBD
Plans:
- 12-01: TBD (run /gsd:plan-phase 12 to break down)
