The verdict: can you vibe code Pebblely?
You can build a solid personal clone of Pebblely in a couple of weeks, but keeping inference API costs manageable while matching complex product shadows will test your prompt engineering.
Replicating the frontend dashboard, image upload flow, and authentication is straightforward with a modern full-stack framework. The real engineering hurdle lies in chaining background removal with an inpainting diffusion model (like Flux via fal.ai) while instructing the model to synthesize realistic contact shadows, surface reflections, and lighting that match the product. Generic text-to-image models tend to make objects look 'floating' unless you carefully compose depth maps and prompt structure. For personal use, paying $9–$39/mo makes financial sense if you generate dozens of photos, but building it yourself is an excellent exercise in AI image pipeline orchestration.
Estimated effort: 2-3 weeks part-time

The hard parts of vibe coding Pebblely
- Precise edge masking on complex objects (transparent glass, fine jewelry chains, wispy edges) without clipping the subject
- Synthesizing physically accurate ambient occlusion, shadows, and reflections that match the generated lighting angle
- Asynchronous queue architecture to handle multi-image batch generation without connection timeouts
- Balancing inference API costs and speed to maintain margins at low subscription tiers

Build guide
01Project Scaffolding & Database Setup
Initialize the Next.js project with Tailwind CSS, configure Turso database connection via libSQL, and set up better-auth for user authentication.
Scramble a new Next.js project configured with TypeScript, Tailwind CSS, and App Router. Set up better-auth with email/password authentication connected to a Turso (libSQL) database. Create a clean dashboard layout with a sidebar navigation for 'New Generation', 'Gallery', and 'Settings'. Ensure all environment variables are properly structured in a .env.example file. Implement a responsive navbar and protect dashboard routes against unauthenticated requests.02Image Upload & Background Removal Pipeline
Build an image dropzone for product photos and integrate a background removal utility or API to isolate the subject.
Create a drag-and-drop image upload component on the dashboard home page supporting PNG and JPEG files up to 10MB. When an image is uploaded, send it to a Next.js Server Action that passes the image buffer to a background removal service or segmentation model (such as rembg or fal.ai segmentation endpoint) to strip the background. Store the resulting transparent PNG in Cloudflare R2 or local storage, and save the asset record to the Turso database with user association. Display a side-by-side preview of the original upload and the isolated subject with a checkered background.03AI Background Generation & Inpainting Interface
Develop the canvas and prompt generation interface where users select themes or type custom prompts to place the product into AI scenes.
Build a generation view where users can select from a grid of preset background themes (e.g., 'Studio white riser', 'Rippling water', 'Wooden table') or enter a custom text prompt. Include controls for product scale, rotation, and horizontal/vertical positioning on the canvas. When the user clicks 'Generate', call a backend API route that interfaces with the fal.ai Flux inpainting API, passing the isolated subject mask and the background prompt. Ensure the generation request handles loading states with a progress spinner and saves generated output records to the database.04Shadow, Reflection, and Aspect Ratio Adjustment
Implement post-processing controls for adjusting shadows, reflections, and output aspect ratios for different social media channels.
Add a customization toolbar to the generation results page allowing users to tweak shadow intensity, shadow blur, and floor reflection opacity. Include an aspect ratio selector (1:1 for Instagram, 9:16 for Stories, 4:5 for feeds) that crops or pads the final composite image cleanly. Ensure all adjustments update a real-time HTML5 canvas preview before exporting the final high-resolution PNG asset.05Gallery, History, and Bulk Download
Build the user asset gallery to review past generations, download images individually or in bulk, and manage project history.
Create a gallery page that fetches and displays all previously generated product photos belonging to the authenticated user from the Turso database in a responsive grid. Implement modal view for inspecting individual images with options to download the high-res asset, delete the record, or re-open the generation parameters in the editor. Add a multi-select checkbox feature to allow bulk downloading selected images as a ZIP archive.

Vibe code Pebblely: FAQ
- Can you vibe code Pebblely yourself?
- Solid side project — 72/100 vibecodeable. You can build a solid personal clone of Pebblely in a couple of weeks, but keeping inference API costs manageable while matching complex product shadows will test your prompt engineering.
- How long does it take to vibe code Pebblely?
- 2-3 weeks part-time — roughly 15-20 hours of hands-on time with an AI coding agent.
- How do you build your own Pebblely?
- Scoped to personal use: Next.js (React) on the front, Next.js Server Actions / API Routes behind it, Turso (SQLite at the edge) for data. Follow the 5-step build guide on this page — each step has a paste-ready prompt for an AI coding agent.
- How do you code your own Pebblely without being an expert?
- Use an AI coding tool (Claude Code or Cursor) and work in small steps: scaffold, data model, core screens, then deploy. Realistic effort: 2-3 weeks part-time. The prompts on this page are written so the AI does the heavy lifting.
- How much does it cost to vibe code Pebblely instead of paying?
- About ~$22 one-time to start and ~$5/mo to run, versus $39/mo (Pro plan) for Pebblely. Break-even: 1 month vs Pro plan.
- What stack should you use to vibe code Pebblely?
