## Immagin

Immagin gives application teams a complete image pipeline without running their own processing servers. Images are uploaded via signed URLs generated by an isomorphic TypeScript client, then served through a global CDN with automatic WebP conversion and immutable cache headers so repeat deliveries stay fast and cacheable.

Transformations are declared in the request URL — resize, crop, text overlays and similar effects — and applied at request time, which means a single source image can fan out into thumbnails, watermarked previews and blurred placeholders on demand. The SDK is zero-dependency and typed, working in Node.js, edge runtimes and the browser, and API keys stay server-side through URL signing.

Pricing is usage-based: a free tier covers small projects, while production traffic is billed by unique transformations in graduated tiers, with cached CDN deliveries always free. Immagin positions itself as a lower-cost alternative to larger image CDNs.

**Pricing & Plans:** Freemium. A free tier includes 1 project, 25,000 unique transforms per month and a free CDN subdomain. Paid usage is metered per unique transformation (roughly $0.20 per 1,000 in the lower band, dropping to about $0.07 per 1,000 at high volume) with Stripe billing; cached CDN deliveries are free.

- **Global CDN delivery:** Automatic WebP conversion, immutable cache headers and edge delivery worldwide keep images fast in every region.
- **Real-time transformations:** Resize, crop and overlay text on the fly; transformations are encoded in the URL and processed at request time.
- **Zero-dependency TypeScript SDK:** An isomorphic, fully typed client that runs in Node.js, edge runtimes and the browser.
- **Signed direct uploads:** Generate signed upload URLs so clients upload straight to storage without a server-side proxy or file-size limits.
- **Usage-based pricing:** Pay only for unique transformations, with cached CDN deliveries always free and graduated per-1,000 rates.

**Strengths:** Simple, typed SDK that works across Node.js, edge and browser; Transparent usage-based pricing that undercuts larger image CDNs at moderate volume; Cached deliveries are free, so popular images don't inflate the bill; Transformations live in the URL, making variants easy to reason about and cache

**Limitations:** Currently image-focused, so video workflows are not part of the offering; Smaller vendor and ecosystem than established image CDN incumbents; Discounts only kick in at high transform volumes

## Stable Diffusion API

Stable Diffusion API gives developers a single HTTP endpoint for the whole Stable Diffusion family and a long list of community checkpoints. Instead of provisioning GPUs, installing PyTorch, and keeping model weights in sync, you send a POST request with a prompt, model id and parameters, and receive generated images plus a track id you can poll or receive via webhook. The catalog the site advertises covers SD 1.5, SDXL, Stable Diffusion 3, FLUX.1 dev/Schnell, FLUX.2 dev, Qwen Image, Z-Image Turbo, video models such as Wan 2.2 and LTX Video, and dedicated families like Realistic Vision, Juggernaut XL, Pony Diffusion, DreamShaper and Illustrious XL.

Beyond plain text-to-image, the API exposes image-to-image, inpainting, upscaling, background removal, ControlNet conditioning, LoRA usage and Dreambooth-style model fine-tuning, so a single integration can cover asset generation, product mockups, advertising variants and interior or fashion visuals. Official code samples for cURL, Python and Node are published for each model page, which shortens the time from signup to a first working request.

The platform is now presented as part of ModelsLab: accounts, API keys and billing live in the ModelsLab dashboard, and the site states that API requests are processed at scale with a 99.99% uptime target. Pricing is transparent and outlined on the site, with plans starting at $21 per month and an unlimited open-source tier for high-volume workloads.

**Pricing & Plans:** Paid plans billed through ModelsLab: Basic $21/month (3,250 API calls, 5 parallel generations), Standard $47/month (10,000 calls, 10 parallel generations), and Open Source Unlimited $149/month or $1,500/year (unlimited generations on self-hosted open-source models, 15 parallel generations). Third-party and closed models are billed separately; Enterprise offers dedicated GPUs and custom SLAs. Creating an account is free, but API access requires a paid plan.

- **Unified REST endpoint:** One POST endpoint handles text-to-image, image-to-image and editing jobs across SD 1.5, SDXL, Flux, ControlNet and LoRA models, with cURL, Python and Node samples for each model.
- **Large community model catalog:** Thousands of community checkpoints and LoRAs, including anime, photorealistic and stylized families, are browsable with their parameters and sample code.
- **Async jobs and webhooks:** Requests return a job id or track id so long-running generations can be polled or pushed to your own webhook endpoint instead of blocking the client.
- **Fine-tuning and training:** Dreambooth-style endpoints let you train custom concepts and styles on your own images, then reuse the resulting model ids in generation calls.
- **Scaling controls and enterprise options:** Parallel generation limits grow by plan, and an enterprise tier provides dedicated GPUs with custom SLAs for high-volume production traffic.

**Strengths:** Single API surface for many base models and thousands of community checkpoints; No GPU provisioning, driver or model-weight maintenance on your side; Publishing-ready code samples for cURL, Python and Node per model; Transparent tiered pricing with an unlimited open-source plan and enterprise GPUs

**Limitations:** API access requires a paid subscription; the free account only unlocks the dashboard; Third-party and closed models are billed separately from the unlimited open-source plan; Call quotas are counted per request, so batch-heavy experiments can consume a plan quickly
