SudoMock is visual infrastructure for e-commerce. A REST API that transforms PSD templates into rendered product mockups in under one second.

The Problem Product visualization hasn't kept pace with e-commerce growth. Manual Photoshop workflows don't scale. Enterprise rendering APIs are expensive. Every product listing needs dozens of images, but the tooling assumes you're making one at a time.

The Solution SudoMock processes Photoshop files server-side at infrastructure-level efficiency. Upload a PSD template with Smart Object layers once, then generate unlimited variations via API calls.

Key Features - Sub-second rendering with CDN-hosted output URLs - $0.002 per render with predictable credit-based pricing - Unlimited Smart Objects per template, no file size limits - Output formats: PNG, JPEG, WebP up to 8000px resolution - Native integrations with n8n, Zapier, and Make - Free visual playground for testing

Who It's For - Print-on-demand sellers (Etsy, Amazon, Shopify) - E-commerce platforms needing dynamic product visualization - Marketing teams automating campaign assets - Developers building product customization tools

Technical Approach Purpose-built PSD processing engine optimized for throughput and cost efficiency. No third-party rendering dependencies. 99.9% uptime, 2M+ renders served.

Pricing Free tier: 500 API credits + unlimited dashboard usage Paid plans start at $19/month with no surprise overages.

Questions & Answers

As answered by people managing SudoMock and StackrApp.

What makes your product unique?

SudoMock's answer

SudoMock runs on a purpose-built PSD processing engine written from scratch in Python โ€” no third-party rendering dependencies, no licensed libraries, no Adobe SDK. This architectural decision eliminates licensing costs and gives us full control over the rendering pipeline. Most competitors wrap existing commercial engines and inherit those costs. We engineered ours specifically for throughput and cost efficiency. The result: sub-second response times at $0.002 per render, with 99.9% uptime and over 2 million renders served.

Why should a person choose your product over its competitors?

SudoMock's answer

Three reasons: Price, Speed, and Simplicity.

Price: At $0.002 per render with no hidden fees, SudoMock is significantly more cost-efficient than alternatives charging $0.05-$0.15 per render.

Speed: Our API responds in under 1 second for most templates. No queue delays, no waiting for workers to spin up.

Simplicity: Upload your PSD once, call the API with your design assets, get a CDN-hosted URL back. We also offer a free visual playground to test before you code, and native integrations with n8n, Zapier, and Make for no-code automation workflows.

How would you describe the primary audience of your product?

SudoMock's answer

Print-on-demand sellers and e-commerce platforms that need product mockups at scale. Our typical users are Etsy, Amazon, and Shopify sellers generating hundreds or thousands of product images daily. We also serve SaaS platforms building product customization features, marketing teams automating campaign assets, and agencies managing multiple client catalogs. Anyone who needs reliable, high-volume mockup generation with predictable pricing is our target audience.

What's the story behind your product?

SudoMock's answer

SudoMock emerged from a gap in the market. Print-on-demand and e-commerce platforms need to generate thousands of product mockups daily, but existing solutions present a scaling problem: enterprise APIs charge $0.05-$0.15 per render โ€” costs that become prohibitive at tens of thousands of images monthly. Meanwhile, budget alternatives sacrifice speed and reliability.

The founding team observed this pattern across the industry โ€” teams either overpaying for enterprise tools or building fragile in-house solutions. The answer was a purpose-built PSD processing engine: no Adobe dependencies, no licensed rendering libraries, just infrastructure optimized for throughput and cost efficiency.

SudoMock packages that engine as a standalone API service. It now serves over 2 million renders for teams who need infrastructure-grade reliability without enterprise pricing โ€” filling the gap between expensive enterprise tools and unreliable budget options.
