SMM Turbo: Hybrid AI Instagram Carousel Editor
SMM Turbo is a free, browser-based graphic editor for creating Instagram carousels that uses a DOM-based architecture built with Svelte 5. The project includes a Hybrid AI Co‑Pilot that combines in‑browser WASM neural networks for background removal and cloud LLMs for text/strategy generation: Groq’s Llama 3.1 (8B) for fast micro-tasks and Google’s Gemma 4 31B via the Google Generative Language API for deep “SMM Strategist” reasoning. To avoid short serverless timeouts the developer moved the Gemma calls to an Edge Function runtime (runtime: 'edge') using native fetch, extending the execution window to ~30 seconds. The editor integrates Supabase for storage/auth, Pixabay for stock images, and exports slides via html-to-image/JSZip. Live demo and source code are published (demo: https://smm.shcho-i-yak.pp.ua, repo: https://github.com/bodikinf/smm-turbo-open).
Demonstrates a practical hybrid on-device/cloud AI workflow for creative automation (in-browser WASM inference + cloud LLMs) and an edge-function workaround for long-running LLM calls; useful example for MarTech/creative tooling but limited commercial scale.

Key Takeaways & Evidence Grounding
- SMM Turbo is a free, browser-based graphic editor for creating Instagram carousels built with Svelte 5 and a DOM-based rendering approach.
- Hybrid AI Co‑Pilot routes micro-tasks to Groq’s Llama 3.1 (llama-3.1-8b-instant) and heavy reasoning tasks to Google Gemma 4 31B via the Google Generative Language API.
- In-browser background removal is implemented using the @imgly/background-removal library loaded as WebAssembly (WASM) to run locally in the browser.
- The Gemma 4 31B calls were moved to an Edge Function runtime (runtime: 'edge') using native fetch to extend execution timeout to ~30 seconds and avoid Netlify’s 10s limit.
- The project integrates Supabase for backend (Postgres + Auth + Storage) and Pixabay for free stock images; source code is on GitHub and a live demo is available.

FreeImgKit: Browser Image Toolkit with WebAssembly
FreeImgKit is a free, browser-based image toolkit launched by developer Amanuel Kidu that performs all processing client-side to avoid uploads and preserve privacy. The suite includes six tools — compressor, resizer, cropper, format converter, social media resizer, and an AI background remover that runs a segmentation model via WebAssembly in the browser. The project is built with Next.js 14 (App Router) and TypeScript, uses the Canvas API for core image processing, relies on @imgly/background-removal (WASM) for segmentation, and is deployed on Vercel with Cloudflare as CDN. Launched five weeks before publication, the site had 13 pages indexed by Google, ~845 impressions in its first month and 69 unique visitors in the first 28 days. The author documents SEO architecture and lessons learned about indexing and FAQ schema.
How to Ship Dynamic Open Graph Images
A technical primer describing practical ways to generate dynamic Open Graph (OG) images for link preview cards. The article outlines three approaches: rendering HTML with a headless browser (Puppeteer/Playwright) for maximum fidelity; using satori/@vercel/og to convert JSX/HTML to SVG without a browser (fast and serverless-friendly); and a hosted URL option (Cardsmith) that delivers images via query parameters using a satori + resvg engine. It also lists trade-offs for each approach, provides code snippets, and gives meta-tag recommendations (og:image size and twitter:card) for reliable social previews. The post is written by an AI agent building Cardsmith and was published on 2026-07-12.
Zero‑Auth Stable Diffusion Playground in 200 Lines
A developer built a single‑file (~200 lines) React TypeScript single‑page app that generates images via Pollinations.ai’s zero‑auth image gateway, requiring no API keys or backend. The app calls a simple URL (e.g., https://image.pollinations.ai/prompt/...?model=flux) that returns an image from Pollinations’ CDN. Pollinations exposes multiple models (flux, flux‑anime, sdxl, sd3, dalle3) and supports query parameters like model, seed, width/height, and enhance (which runs prompts through a small LLM to expand them). The playground stores generation metadata in localStorage, supports favorite/seed‑locking/download, and is deployed as a static SPA on Vercel. The author notes licensing limits (personal use vs. commercial restrictions for some models) and outlines extensions (inpainting/mask, image‑to‑image, batch generation, or self‑hosting Pollinations).
